4 – Parts of the DM-24—Top surface TASCAM DM-24 Reference Manual 31 PSTORE key This key stores the current set- tings to the currently-selected library entry. Parameter control section This section is used to control the different parame- ters and to navigate through the different options available on the DM-24 QLCD display This backlit display shows the parameters and values that can be adjusted, as well as popup status and error messages. RSoft keys These four keys are used to select options and sub-screens shown at the bottom of the display (“Soft keys” on page 15). SPODs These encoders are used to set values highlighted on the screen with the cursor (“PODs” on page 13). TDisplay contrast Use this control to set the most convenient viewing angle for the display. UCursor keys These keys are used to move the on-screen cursor to highlight the parameters to be edited with the PODs or the data dial. VNumber and predefined function keys These keys are used to access the setting screens where global parameters may be set up and for changing between sub-screens. The SHIFT key is also used to provide a secondary function for most of these keys, bringing up screens which probably will not be used so frequently. In some location modes, these keys are used to enter numeric values directly: WSHIFT key and indicator This is a “smart” key. Press and release it briefly to light the indicator. Press and release it briefly again to turn off the indicator. Press and hold the key for more than about half a sec- ond to light the indicator for only as long as the key is held down (when the key is released, the indicator goes out). When the indicator is lit, the predefined function keys will then perform their secondary shifted func- tion (as marked on the lower label above the key). XLOCATE keys and indicators These keys are used to set the way in which location of the currently-selected machine transport is controlled. If any of these indicators is lit, the predefined func- tion keys act as number keys (as explained in “Loca- tion memories” on page 85). YAUTOMATION UNDO key This key is used with the automation system to undo changes made to automated mixes. ZJOG/DATA dial This dial is used for setting on-screen parameter values, etc. When the DM-24 is controlling the transport of a remote device, it may be used to perform a jog function.

4 – Parts of the DM-24—Top surface 32 TASCAM DM-24 Reference Manual aENTER key Use this key to confirm entries and to answer “yes” to questions (the cursor keys are usually used to cancel or answer “no”). Monitoring section This section is used to control what is heard from the control room and the studio monitoring systems. Since many of the choices here are “soft” choices (that is, determined by the software), the full expla- nation of these keys and indicators is provided in a separate section (“Monitoring” on page 73). bMeters These meters show the level of the currently-monitored signal. cSOLO control and indicator When the indicator is lit, soloing is enabled and a channel has been selected for soloing. The level of the soloed sig- nal is controlled by this knob. dPHONES control This control regulates the level of the signal sent to the phones outputs. eMonitor selection keys These keys are used to select the signal sent to the control room monitor outputs (and the phones outputs). The STEREO key routes the stereo output signal to the monitor outputs. The SEL 1, SEL 2 and SEL 3 keys route the signals selected in the monitor screen to the monitor outputs. fTalkback microphone This integral microphone can be used for studio talkback or slate output. gDIM key and indicator This “smart” key works in the same way as the STUDIO key above. When on, the control room outputs are attenuated (the amount is set using the monitor screen). hMONO This outputs the selected signal in mono to the control room monitors and phones. iSTUDIO key and indicator This “smart” key latches on when pushed and released within a second, and is switched off by pushing it again in the same way. If pushed and held down for more than a second it is non-latching, that is, it turns off when released. When on, the control room outputs are attenuated, and the talkback microphone signal is routed to the studio outputs. jCR volume control This control adjusts the level of the signal selected with the selection keys and sent to the control room outputs and PHONES outputs. kTO SLATE key and indicator This “smart” key works in the same way as the STUDIO key above. When on, the control room outputs are attenuated and the talkback microphone signal is routed to the eight output busses, the stereo buss and the six aux busses. lT/B volume control This control adjusts the level of the signal from the talkback microphone, fed to the selected outputs (slate or studio). m,./!@ # $%^ &
4 – Parts of the DM-24—Top surface TASCAM DM-24 Reference Manual 33 Module faders and selection, etc. The module faders are arranged in layers (see “Fader layers” on page 18). Accordingly, the 16 module fad- ers are used to control all 32 inputs, the six aux sends and the output buss sends as shown on the pre- printed labels above and below each channel strip. Note that a wipe-off surface is provided (below the REC keys) for you to write in soft pencil the func- tions of the channels (equipment connected to the DM-24, etc.). mREC key These keys, with integral indicator, are used to set and show the recording status of tracks of devices controlled by the DM-24. nSEL keys These keys, with integral indica- tors, are used to select the modules for editing opera- tions, as well as for stereo linking and other editing functions. The indicators light to show which module has been selected. oMUTE keys These keys, with integral indica- tors, show the muting status of the modules. When used with the solo modes, they give instant indication of what module(s) are selected for soloing. pOL/STATUS indicators These indicators may be selected using software to show either over- load to the input channels or the current status of the channel when automation operations are being car- ried out. See “OL/STATUS LED TYPE” on page 20 for details of these settings. qModule faders These 100 mm motorized faders are labeled from ∞ (full cut) to +10 (dB). The 0 position may be set to be equivalent to the appro- priate full-scale value using software. rALL SAFE key This key, with integral indi- cator, is used to “safe” any tracks of recording devices controlled by the DM-24. sSOLO key This key, with integral indicator, is used to enable the soloing function as selected in “SOLO” on page 22. tSTEREO fader This fader does not change function as the layers are changed, but controls the level of the stereo outputs. It is labeled from ∞ (full cut) to 0 (full scale). uLAYER STATUS keys These keys (with integral indicators), as explained in “Fader layers” on page 18, change the function of the modules to pro- vide access to the different fader layers. Transport and automation control This controls in this section provide remote control facilities for recording devices, etc. attached to the DM-24. vREPEAT key This key, with integral indica- tor, is used to control repeat playback. wALL INPUT key Provides input monitoring for all tracks on the selected unit(s). xAU TO MO N k ey Provides automated switching between input and off-tape monitoring. yAUTO PUNCH IN/OUT keys Typically used with the DTRS family of recorders. zTransport keys and indicators The exact function of these keys ( REW, F FWD, STOP, PLAY and RECORD) and indicators depends on the device currently selected for external control. * ( ) Q WE T R Y UI O P AS
4 – Parts of the DM-24—Rear panel 34 TASCAM DM-24 Reference Manual SAutomation control keys and indicators These keys (REHEARSE, WRITE, TRIM and REVERT) are used to control the automa- tion functions. These keys have other functions, as selected by the 2ND F key (F). NOTE Although some of these keys have similar names to other keys on the DM-24, note that their functions are restricted to automation operations. Rear panel The rear panel of the DM-24 houses the digital audio and control connections. NOTE Only use TASCAM-supplied and TASCAM-approved cables when making digital audio and control connec- tions to the DM-24. Though the cables and connectors may resemble computer cables, they serve different purposes, and meet a different set of specifications. The use of cables other than TASCAM cables will at best cause the equipment to work erratically, and at worst cause damage to the equipment. If the use of cables other than TASCAM cables causes or results in damage, the warranty is voided. 1TO METER This 25-pin ‘D’-sub connector is used to connect the DM-24 and the optional MU-24/ DM meter unit. 2ADAT [IN, OUT] Use these “lightpipe” con- nectors to connect ADAT-compatible units to the DM-24 with a Toslink-type optical cable. Each of these connectors carries eight digital audio input or outputs channels.The input may be used as a clock source, and routed to any of the three groups of eight input channels (1 through 8, 9 through 16, 17 through 24). 3WORD SYNC [OUT/THRU, IN] and switch These BNC connectors are used for word sync. The switch controls the behavior of the connec- tors (75Ω input impedance and switching between OUT and THRU functions) as described here: A THRU setting means that the connector echoes the word sync signal received at the IN. An OUT setting means that the DM-24 originates a word sync signal (and is therefore to be the word sync master for the system). 1 23 4 56 7 8 9 ABCDE Position75Ω IN termination?OUT/THRU Left No Thru CenterNo Out RightYe s O u t
4 – Parts of the DM-24—Rear panel TASCAM DM-24 Reference Manual 35 4TDIF [1, 2 3] These 25-pin ‘D’-sub connec- tors are used for the connection of suitably-equipped digital audio devices. At the base rates of 44.1k and 48k, each connector carries eight channels of input and eight of output. These numbers are halved when dual-frequency sam- pling frequencies (88.2k and 96k) are used. These may be routed to any of the three groups of eight channels capable of accepting return signals (1 through 8, 9 through 16, 17 through 24). TDIF 1 only may be selected as the clock source for the system. 5MIDI IN, OUT and THRU These three 5- pin DIN connectors correspond to the MIDI standard ( MIDI IN receives MIDI data, MIDI OUT outputs MIDI data originated by the DM-24, and MIDI THRU echoes data received at MIDI IN). The MIDI is used for MIDI Timecode, Program Change and Control Change messages, as well as for MIDI System Exclusive bulk data dumps, etc. The details of these are all given in the section on MIDI (“MIDI” on page 95). 6EXT SW This 1/4” jack is used to connect a footswitch (for example, the TASCAM RC-30P), which is selectable through software to provide a variety of functions. 7TIME CODE This unbalanced RCA connec- tor accepts SMPTE/EBU analog timecode. 8DTRS REMOTE CONTROL This 15-pin ‘D’-sub connector connects to the first unit in a chain of DTRS recorders, allowing the DM-24 to remotely control the recorders. 9SLOT [1 and 2] These expansion slots allow the fitting of optional cards, such as a cascade card, AES/EBU interfaces, additional “lightpipe” inter- faces, or additional AD-DA conversion interfaces.Consult your TASCAM dealer for availability of such cards, and the documentation supplied with the cards for details of how to fit and use them. APOWER SWITCH and IN Use this push- on/push-off switch to switch the power to the DM- 24. Use only the provided power cord to connect the DM-24 to the AC supply, ensuring that the voltage of the supply matches the voltage requirements as given on the rear panel of the DM-24. If you are in any doubt, consult a qualified electrician. NOTE The equipment draws nominal non-operating power from the AC outlet with its POWER switch in the OFF position. BDIGITAL OUTPUT 1 and 2 Each of these outputs has two connectors: an XLR-type and an RCA connector. The format of the output is deter- mined by software. The function of these connectors (master stereo out- put, stereo aux send, etc.) is also determined by soft- ware settings. CDIGITAL INPUT 1 and 2 Each of these inputs has two connectors: an XLR-type and an RCA connector. Only one connector at a time can be used for the input (selected by software). The routing of these connectors is also determined by software settings. DGPI This 9-pin ‘D’-sub connector is a General Purpose Interface, used for remote control of devices attached to the DM-24. ERS-422 This 9-pin ‘D’-sub connector is a remote control interface, to the RS-422 standard, allowing remote control of devices attached to the DM-24.
36 TASCAM DM-24 Reference Manual 5 – Setting up the I/O Because the DM-24 is a “soft” digital mixing con- sole, there are few of the hard-wired assignments that you find on an analog console. In addition, the DM-24 includes an internal patchbay, which allows routing and splitting of signals within the console, providing a high degree of flexibility, and easy re-configuration when the requirements within a project change. These routing and configuration settings can be stored in snapshot settings, allowing easy switching between the commonly-used routing patterns (for example, tracking, overdubbing and mixdown).The library facilities also allow the retention of I/O patches, etc. between snapshots, so that the I/O set- tings are not always overwritten by the recalled snap- shot. See “Protecting snapshot settings” on page 102 for full details. NOTE This section deals only with the assignments in normal sampling frequency modes (either 44.1 k or 48 k). If the DM-24 is to be used in high sampling-frequency mode, the screens and the options are a little different. See “High sampling frequency” on page 112 for details. Signal sources The DM-24 defines channel signal sources as inputs and returns, as explained here. In the I/O assignment screens, each channel from 1 through 24 has two different sources—input and return—available (channels 25 to 32 have only one source—input—available): In this illustration, the mic/line inputs are selected as the inputs (upper box) for channels 17 through 24. The ADAT connector audio is selected as the return source (lower box) for these channels. Sixteen mic/line analog inputs are avail- able on the DM-24. These are referred to on-screen as M/L. They may be assigned to the console channels num- bered 1 through 32. These are inputs. Three TDIF connectors (1 through 3) carry eight channels of I/O digital audio each (in base fre- quency mode—in dual-frequency mode, this situa- tion is different). These TDIF inputs may also be assigned to console channels numbered 1 through 24. These are returns. ADAT connector The single “lightpipe” ADAT input connector carries eight channels of digital audio input. The eight audio channels received through this con- nector may be assigned to any of the console chan- nels numbered 1 through 24. These are returns. DIGITAL IN 1 & 2 Each of these logical inputs has two physical connectors: an XLR, typically used for AES/EBU connections, and an RCA jack, typically used for SPDIF connections. One of these can be selected for each logical input, and routed to any of the console channels numbered 1 through 32. These are inputs. Card slots Optional cards may be installed in the two card slots for expansion of the digital and analog I/O. These are treated as returns, and may be routed to the channels 1 through 24. Assignable returns These four balanced analog inputs may be assigned as channel inputs (for exam- ple, when they are used with external effect proces- sors). These are inputs and are assignable to channels 1 through 32. Internal effectors The DM-24 has two internal digital effectors, with stereo returns. These returns are inputs and are assignable to chan- nels 1 through 32. inputs returns
5 – Setting up the I/O—Output signals TASCAM DM-24 Reference Manual 37 Output signals The following are the signals output from the DM-24 (excluding the monitoring signals): Eight output busses These busses are typically routed to the built-in multi-track outputs (TDIF and ADAT) or to the optional slot cards. Six aux busses These six aux busses may be routed to the assignable sends, as well as to the inter- nal effect units. Stereo master outputs These stereo outputs are typically used as the sum of the mixed output busses (except in surround mode). Direct outputs The signals from the channels can be output directly, not passing through busses, etc. to the connectors (TDIF, ADAT, slot) below. Physical outputs This excludes the monitoring outputs (control room, studio, etc.). TDIF-1 connectors These connectors are used as outputs as well as inputs, carrying eight channels each in normal-frequency mode. In dual-frequency mode situation this is different. ADAT OUT connector This lightpipe connector can be used as outputs from busses or as direct out- put. It carries eight channels in normal-frequency mode. Slot cards These may act as outputs, depending on the cards installed. Assignable sends These sends may be used as either analog insert sends or as aux sends. Digital outputs (x 2) Can be assigned to output the stereo buss, adjacent pairs of busses, adjacent pairs aux busses or the control room source. STEREO OUTPUTS (L, R) Used as the analog outputs for the stereo master buss. Patching between input and return The DM-24 allows you to switch between the assigned inputs and returns for channels 1 through 24 without having to connect or disconnect cables. The sources for channels 25 through 32 are not selectable in this way. These switches are accessed from the I/O screens. 1With the SHIFT indicator lit, press the I/O key. 2Press either the first or second soft key to bring up the channel assignment screens. The on-screen channels have two columns, the sources, and the destinations, with a “patch cable” connecting them. The source column has two alternative sources for each channel: the input (top) and the return (bottom) sources. Move the cursor to the “patch cable” and turn the dial. 3Press ENTER to confirm the change. NOTE This switching can also be done in the fourth MODULE screen (“Channel source (CH SOURCE)” on page 58). Mic/line input 1 is routed to input channel 1 The cursor is moved to high- light the “patch cable” The dial has been turned to “repatch” TDIF1 channel 1 to channel 1 The ENTER key has been pressed to confirm the re- patching process.
5 – Setting up the I/O—Assigning inputs to channels 38 TASCAM DM-24 Reference Manual Assigning inputs to channels The I/O screens control the input/output assignments, as explained here: 1With the SHIFT indicator lit, press the I/O key. There are four tabs at the bottom of the screen. The two leftmost tabs, accessed through the first two soft keys, control the inputs to the first sixteen ( CH1-16 IN) and sec- ond sixteen ( CH17-32 IN) channels, respec- tively. 2Press either of the two soft keys described above. These screens control the selection of the return block, the input source, and the choice between input and return for each channel, as well as the input source for the DIGITAL IN signals. Each of the channels from 1 through 24 can be used either as an input or a return, as described above. In the screen above, the mic/line inputs are assigned to the first sixteen channels, which would be an appropriate setting for the recording phase of a project. In the screen below, however, tape returns from TDIF groups 1 and 2 are assigned to these channels (for mixdown). Channels 25 through 32 can be used for input only. Input sources Any mic/line input can be assigned to any channel (1 through 32). The same mic/line input can be assigned to more than one channel, if required. 1In either of the two channel I/O screens, move the cursor to the source column of the group of channels. 2Use the § and ¶ keys to move up and down the column. NOTE Note that the returns (as explained below) are pre- mapped and cannot be changed here. The cursor never highlights them. 3Use the dial to select from the available options as listed here ( x represents a dis- played number in this table): NOTE Since input sources can be shared (routed to more than one input at once), simultaneous recordings can be made of the same take. For example, you can try recording the same vocal take with different compres- sion or EQ settings.

5 – Setting up the I/O—Assigning inputs to channels TASCAM DM-24 Reference Manual 39 Return modules Return sources are available for channels 1 through 24 (channels 25 through 32 are input only). The return options for each group of eight channels are selected by moving the cursor to the RETURN field at the left of the list of channels, and using the dial to select from the available options. Press ENTER to confirm the setting. NOTE If a slot card has not been fitted, an error message appears. Press ENTER to dismiss the message. Each group of eight channels is assigned to use the same return source block (though it is possible to mix inputs and returns within the same block). It is important to note the following: The returns from TDIF1-1 cannot be assigned and used at the same time as the returns from a card fit- ted in slot 1. The returns from TDIF1-2 cannot be assigned and used at the same time as the returns from a card fit- ted in slot 2. The returns from TDIF1-3 cannot be assigned and used at the same time as the returns from the inter- nal ADAT connector.The first 24 channels may have the following sources assigned to them as returns: As can be seen, it is possible for the same return to be assigned to more than one channel at the same time (of course, it is not possible for one channel to accept the signal from more than one return at the same time). Although the return module for each block can be selected, the channels of the module cannot be changed. For example, if an MTR return is assigned to channels 1–8, track 2 of an MTR cannot be assigned to channel 1. Track 3 can only be assigned to TDIF channel 3 (in the TDIF1, TDIF2, TDIF3 return source blocks), or ADAT channel 3, etc. Note, though that when slot cards are fitted, the num- ber of the channel in the slot card may be offset by 8 or 16, so that channel 9 (or 17) of slot card 2 may be assigned to channel 1, etc. Digital inputs Each digital input has two connectors; an XLR-type connector and an RCA pin jack. One of these is selected for input as described here. These connectors can both be used for either AES/ EBU or SPDIF data, and the data format is automati- cally detected by the DM-24—no settings are neces- sary to choose the data format.See “The FORMAT screen” on page 26 for details of how to set the parameters for sampling frequency conversion, etc. at these inputs. However, although there are two physical connectors for these inputs, the audio data for an input can only be accepted from one of these connectors at any one time.

5 – Setting up the I/O—Channel-to-buss assignments (global) 40 TASCAM DM-24 Reference Manual The inputs are chosen in a similar way to the input/ return selection for channels 1 through 24. The cursor is moved to the “patch cord” linking the inputs to the digital input (either D IN1 or D IN2), and the dial and ENTER key are used to change the “patch” setting. Channel-to-buss assignments (global) These may be made either on a central “global” basis, or individually, channel by channel. NOTE Surround modes are treated in a similar, but different, manner. See “Surround operations” on page 107 for full details of how to make assignments in surround mode. To use the global screen: 1With the SHIFT indicator off, press the ASSIGN key. 2Continue to press the ASSIGN key, or press soft key 3 to display the BUSS screen. 3Use the Ó and Á keys or dial to move the cursor along the row. The § and ¶ keys move between the blocks, and the SEL indi- cator of the currently-highlighted channel lights (if the fader layer containing the chan- nel is selected). Alternatively, use the SEL keys of the chan- nels to move the cursor and highlight the channels on the screen. Channel 1 is high- lighted here. 4Use POD 4 to move the cursor at the right of the screen to select the buss groups ( 1-2, 3-4, 5-6 and 7-8), the stereo output (ST), direct out ( DIR) or AUX 1-2 (see below). 5Press ENTER to assign/de-assign the high- lighted channel to and from the selected group. The appropriate CH ASSIGN key indi- cators light and go out as the selections are made in this way. Alternatively, if the SEL key of the selected channel is lit (that is, the fader layer of the selected channel is active), use the dedicated ASSIGN keys to change the assignments. NOTE Direct output is only possible from channels 1 through 16. Master settings The on-screen buttons ALL CH ON (soft key 1) and ALL CH OFF (soft key 2) are used to assign or de-assign all channels from the assignment highlighted using POD 4. AUX 1-2 The AUX 1-2 setting at the bottom of the POD 4 list does not have a corresponding hardware key or indicator. It is used to switch a link between the stereo output and aux 1-2, or aux 1-2 may be assigned to the stereo outputs. Obviously, only one of these assignments may be made at one time. The first of these assignments (stereo to aux 1-2) is only possible when the AUX 1-2 POD 4 button is high- lighted, and when the cursor is on the ST module (bottom right of screen). The second such assignment (aux 1-2 to stereo) is possible only when the AUX 1-2 POD button is not highlighted, and the cursor highlights the AUX mod- ule (to the left of the ST module—lower right). In either case, press the ENTER key. If the other assignment has been made, a popup message appears RCA XLR
