4 TASCAM IF-AE8HR TASCAM IF-AE8HR 1 Introduction The TASCAM IF-AE8HR provides a convenient way of exchanging digital audio data between TDIF-1- equipped devices, such as DTRS recorders, and AES/ EBU devices. A single TDIF-1 connector carries eight channels of digital input and output. Four XLR-type connectors accept four two-channel input signals, and another four XLR-type connectors output four two-channel input signals. The word synchronization is selectable, using a front panel switch, from any of the four XLR-type inputs, from the TDIF-1 source, or from an external inde- pendent word clock source. The IF-AE8HR allows high-resolution (up to 24 bits) audio data to be transferred between units. No set- tings are necessary to set word length. In addition, four channels of high-frequency audio data at 88.2 kHz or 96 kHz may be selected from the front panel and transferred using the IF-AE8HR. Separate word clock outputs are provided for either high-frequency or normal-frequency data clocks. When a high-frequency data rate (88.2 or 96) is selected, the IF-AE8HR provides a choice of how the data is physically transmitted: either using a single high-speed connection ( HI SPEED) or two parallel “normal” speed connections ( DUAL). The audio data format output from the XLR-type outputs may be selected from the front panel as either AES (professional— PRO) or as IEC-60958 TYPE II (SPDIF— CONSUMER). Consumer and professional formats received at the XLR-type inputs are automatically distinguished by the unit. 1.1 Mounting, etc. The IF-AE8HR is a 1U unit, designed to fit into a standard 19-inch rack. Included in the package are; The unit itself This manual A rack-mounting kit A 2 m (6 ft.) power cord Four rubber feet If any of these items are missing, contact your TAS- CAM distributor. Install the unit in the 19” rack as shown below: 2 Front panel 1Power switch and indicator Push the POWER switch once to turn on power, and again to turn it off. The POWER indicator lights when power is supplied to the IF-AE8HR. Note that settings made are not memorized. When- ever the power is turned on, the CLOCK source is set to WORD 3, the SAMPLING FREQUENCY is set to 44.1k 4and the CHANNEL STATUS is set to PRO 5. 2LOCK indicator When a valid clock signal is received at the selected clock source, this indicator will light. If this indicator starts to flash, the IF-AE8HR is not locked to the external clock (as specified by 3). This 13245
TASCAM IF-AE8HR TASCAM IF-AE8HR 5 occurs if there is no clock signal or the signal is ±6% outside the nominal frequency. In these cases, once a valid clock signal is received again, the indicator will light steadily. 3CLOCK switch and indicators This switch allows you to cycle between the six pos- sible clock sources for the IF-AE8HR: the WORD SYNC – IN 9 connector, the DIGITAL I/O (TDIF-1) 8 connector, or any of the four two-channel AES/ EBU connectors ( DIGITAL I/O (AES/EBU) INPUTS (1/2, 3/4, 5/6, 7/8) 7), as shown by the indicators to the right of the switch. NOTE There should usually never be more than one word clock signal in a digital audio system. If there is more than one word clock, at worst, damage may occur to speakers, amplifiers, etc. as a result of high-frequency noise gener- ated by word clock incompatibilities, etc.. 4SAMPLING FREQUENCY switch and indicators This switch allows you to select the sampling fre- quency at which the IF-AE8HR outputs data, either to the XLR-type connectors, or to the TDIF-1 con- nector: 44.1k, 48k, 88.2k or 96k. There are also two other settings that may be selected with this switch: DUAL and HI SPEED, which only become options when one of the high-frequency options ( 96k or 88.2k) has been selected. Repeated presses of this switch will cycle between the follow- ing settings: = LED off ❍ = LED on DUAL mode and HI SPEED mode (AES format) Usual mode (FS=44.1 or 48) In this mode, one XLR-type connector carries two channels of data. Since the IF-AE8 is provided with four such XLR-type connectors for input and four for output, the data for eight channels can be transferred in total. DUAL mode (Fs=88.2k or 96k) Data is transferred in over two channels in the DUAL mode. In high-frequency sampling modes (88.2k and 96k), there is twice the amount of data compared to the usual modes (44k and 48k). In DUAL mode, one XLR-type connector carries the data for one channel, allowing four channels in total to be transferred. In this mode, channel 1 is carried by connector 1-2, channel 2 by connector 3-4, channel 3 by connector 5-6, and channel 4 by connector 7-8. HI SPEED mode (Fs=88.2k or 96k) In the HI SPEED mode, data is transferred at double speed. As mentioned above, in high-frequency sam- pling modes (88.2k and 96k), there is twice the amount of data compared to the usual modes (44.1k and 48k). Here, the transfer speed is doubled, so that one connector can carry two channels’ data. In theory, this would allow eight channels to be trans- ferred at high speed, but for the reason below, only four channels may be transferred using the IF- AE8HR. NOTENOTE In TDIF version 2 format, only the DUAL mode is sup- ported. If HI SPEED is selected, only DIGITAL I/O (AES/EBU) connectors 1-2 and 5-6 are used. Therefore, INPUT and OUTPUT terminals 3-4 and 7-8 cannot be used in this mode. Error modes These LEDs are also used as error indicators, to show an error condition with regard to the input signals. The selected frequency indicator will flash to show an error under the following circumstances. When appropriate steps are taken to correct the problem, as shown below, the indicator will stop flashing and will light steadily. The sampling frequency of the signal at the AES/ EBU inputs and the TDIF-1 connector differ. Cor- rect the sampling frequency settings of the attached units. The TDIF-1 connection is not made properly. Make sure that it is connected correctly. The signals at the four AES/EBU inputs have dif- ferent sampling frequencies. Make sure that all sig- nals received at these connectors are at the same sampling frequency. Incorrect data is being received at one of the AES/ EBU inputs. Make sure that all data sources are correctly set up. 44.1k 48k 88.2k 96k DUALHI SPEEDMeaning ❍44.1 kHz ❍48 kHz ❍❍88.2 kHz DUAL ❍❍96 kHz DUAL ❍❍88.2 kHz HI SPEED ❍❍96 kHz HI SPEED
TASCAM IF-AE8HR 6 TASCAM IF-AE8HR NOTE If WORD is selected as the clock source, and a high- frequency sampling frequency has been selected (88.2k or 96k), but the incoming word sync clock is normal speed, note that this is not shown as an error by flashing indicators. 5CHANNEL STATUS switch and indicators The format of the digital audio output from the AES/ EBU output connectors 6 may be either profes- sional AES format ( PRO) or CONSUMER IEC-60958 TYPE II format. The electrical characteristics of the output connectors remain the same, regardless of the data format selected. As mentioned below, the input format is automatically selected, and no setting is necessary to determine the input data type. NOTE Since the consumer standard does not provide for high-frequency (88.2 kHz or 96 kHz) data rates, any attempt to select CONSUMER and either of the high- frequency rates (88.2k or 96k) will not work. This is shown by the PRO indicator flashing for about two seconds, and then returning to a steadily-lit state. 3Rear panel 6DIGITAL I/O (AES/EBU) OUTPUTS (1/2, 3/4, 5/6, 7/8) These balanced XLR-type connectors output digital audio data in AES/EBU professional or in consumer format, depending on the selection made with the CHANNEL STATUS switch 5. The sampling frequency of the output data depends on the setting of the SAMPLING FREQUENCY switch 4, and the currently-selected clock source 3. 7DIGITAL I/O (AES/EBU) INPUTS (1/2, 3/4, 5/6, 7/8) These balanced XLR-type connectors accept digital audio data in AES/EBU professional or in consumer format. The data type is automatically selected and no setting is necessary. Note that there are four independent detection cir- cuits, meaning that a mix of consumer and profes- sional format signals may be input at these four inputs. However, all the signals must be at the same sampling frequency. Also note that if a signal with emphasis is received at any input, the resulting output signals will all contain emphasis. The signal received at any of these connectors can be selected as the clock source for the IF-AE8HR using the CLOCK switch 38DIGITAL I/O (TDIF-1) Use this connector to connect a suitably-equipped TDIF-1 digital audio unit (e.g. a DTRS recorder or a TASCAM digital mixing console). The signals received at this connector can be selected as the word clock source using the CLOCK switch 3. NOTE Note that you should always use genuine TASCAM cables, or cables which have been approved for use with TDIF-1 interfaces by TASCAM. Although these cables appear similar to certain types of computer cables and use similar connectors, the cables themselves are very different, and the different electrical characteristics of the cables can cause damage to the equipment connected with the wrong cables. If the use of cables other than TASCAM cables causes or results in damage, the warranty is voided. 9WORD SYNC – IN The BNC connector accepts a word clock signal from an external source. It can be selected as the word clock source for the IF-AE8HR using the CLOCK switch 3. If a high-frequency sampling frequency ( 96k or 88.2k) has been selected, it is possible to use either the appropriate high-frequency word clock, or the corresponding standard-frequency word clock. 789ABCD 6
TASCAM IF-AE8HR TASCAM IF-AE8HR 7 AWORD SYNC – THRU (AUTO TERM) This BNC connector echoes the word clock which is input at the WORD SYNC – IN connector 9. If no connection is made to this connector, it is auto- matically terminated. BWORD SYNC – OUT (STD Fs) This BNC connector outputs a standard-frequency word clock: either 44.1 kHz when 44.1k or 88.2k is selected, or 48 kHz when 48k or 96k is selected. CWORD SYNC – OUT (HI Fs) This BNC connector outputs a high-frequency word clock: either 88.2 kHz when 44.1k or 88.2k is selected, or 96 kHz when 48k or 96k is selected. NOTE These clocks output from B and C may or may not be the same as the clock received at WORD SYNC – IN 9 and retransmitted through WORD SYNC – THRU (AUTO TERM) A. However, they are always the word clock selected using the CLOCK switch 3. D~ IN (power in) Use the supplied power cable to connect the IF- AE8HR to the power supply. Always ensure that your power supply matches the requirements marked on the rear panel of the unit. If you are in any doubt, consult a qualified electrician. 4Block Diagram 5 Specifications DIGITAL I/O (AES/EBU) INPUTS connector type XLR3-31-type, balanced, 110 Ω input format Auto-detect PRO AES3-1992 Amendement 3-1999 (AES) and CONSUMER IEC-60958 TYPE II formats DIGITAL I/O (AES/EBU) OUTPUTS connector type XLR3-32-type, balanced , 110 Ω output format Switchable between PRO AES3-1992 Amendement 3-1999 (AES) and CONSUMER (IEC-60958 TYPE II) for mats DIGITAL I/O (TDIF-1) connector D-sub 25-pin female unbalanced format Follows the TDIF-1 version 2 specification Word clock source AES/EBU, TDIF-1, or WORD SYNC IN Valid input and output Fs rates 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz (all ±6%) Word length Up to 24 bits WORD SYNC IN Connector BNC CPU TDIF DIO AES/EBU DIO ROM INPUTS DIGITAL I/O ( AES/EBU ) LINE DRIVER LINERECEIVER LOCK CLOCK SOURCE WORD IN TDIF-1 AES(1-2,3-4,5-6,7-8) SAMPLING FREQUENCY 44.1k 48k 88.2k 96k DUAL HI SPEED CHANNEL STATUS PRO CONSUMERKeys and indicators WORD INTHRU OUT PLL x 512 512Fs512Fs (RECEIVER) OUT 4 4 Fs/2 Fs/2 Fs/TDIF Fs/AES INPUT SELECTOR 4 44 4 D ATA x 1 x 2 OUTPUTS DIGITAL I/O ( TDIF-1 ) 1-2 3-4 5-6 7-8 (STD FS) (HI FS) PLL 1-2 3-4 5-6 7-8
