JBL Synthesis System Configuration 32 Customization After you have calibrated and customized the SDP-3, there are two additional steps recommended to safeguard the settings. First, docu- ment your adjustments using the worksheet at the end of this manual. Second, consider locking the settings so that they cannot be inadvert- ently changed. The last item in the Setup menu allows you to lock the SDP-3 settings, as well as to change the name displayed during power up. Locking Settings Locking the settings allows full operation of the unit but prohibits the ability to change effect parameters or setup values. Specifically, with the settings locked, the unit will allow any Parameter or Setup menu to be displayed, but attempting to select any item for adjustment will display the message: SETTINGS ARE LOCKED. In order to prevent accidental changes, select the SETTINGS param- eter and use ▲ to select LOCKED. A higher level of security can be achieved by simultaneously pressing Record/Zone 2 on the remote, then pressing FX ▲ (with SETTINGS selected). Repeat to release lock. Assign Custom Name When the SDP-3 is first turned on, it displays a copyright notice with the current software version. You can choose to have it display CUSTOM- IZED FOR DEMONSTRATION with the word DEMONSTRATION scrolled in from right to left, or you can replace the word DEMONSTRA- TION with a custom name of as many as 20 characters. To assign a new name, use ▲ and ▼ to highlight CUSTOM NAME. Press SELECT and press s to turn this function ON, then press DONE. You will return to the Lock Settings menu with ASSIGN CUSTOM NAME highlighted. Pressing SELECT will display the current name with a cursor indicating which character position can be modified. Use ▲ and ▼ to select a new character. Use SELECT to move the cursor to a new position. Press DONE to save the new name. LOCK SETTINGS MENU SETTINGS CUSTOM NAME ASSIGN CUSTOM NAMEUNLOCKED OFF

Using SDP-3 Effects
When EFFECT ADJUST is selected from the Main menu, the on-screen
display shows a list of parameters specific to the current effect, as well
as the current value of each parameter. (The front panel display shows
one parameter at a time). Use the ▲ and ▼ buttons to move through the
displayed list. Press SELECT to activate a two-line display which allows
you to use ▲ and ▼ to alter the selected parameter’s value. Press DONE
to confirm the change and move on to the next menu item. Each SDP-
3 Effect and its parameter menu is described in the following sections.
Customizing Effects
Although the list of available parameters will vary with different effects,
the last item in each menu is always CUSTOM. Selecting CUSTOM
calls up a sub-menu which allows you to name your custom effects, to
compare your version with the original preset, or to restore the preset
versions of the Effect name and parameter values.
When first shipped, the SDP-3 has a set of default values assigned to
each Effect. These values have been determined to be suitable for initial
listening. As every installation has its own unique characteristics, and
listeners have distinctly different preferences, you may want to tailor the
Effects to suit your own requirements. To allow easy customization, any
parameter changes you make take effect instantly, and automatically
become part of the Effect. You can even change the name that appears
on-screen. Once you have made the changes you want, the Effect will
remain as you have set it unless you alter it again, or deliberately restore
the factory preset parameter values.
Selecting CUSTOM from any Effect Adjust menu will give you access
to the controls listed to the side and described below. Use ▲ and ▼ to
highlight any menu item, then press SELECT to open the submenu.
Comparing a modified Effect to the factory preset version
LISTEN CUSTOM/PRESET lets you compare your edited version of an
Effect with the original version as set at the factory. When this control is
selected, ▲ and ▼ allow you to alternate between the "preset" and your
modified version ("custom"). The display will confirm whether you are
LISTENING TO CUSTOM or PRESET.
Note that this function is available, even if you have not made any
changes to an Effect. Until you make parameter changes to create a
custom version of a preset, the LISTEN TO CUSTOM option will contain
an exact duplicate of the preset Effect.
Exiting this menu restores the CUSTOM version.

JBL Synthesis System Configuration 34 Restoring the original parameter values of an Effect The RESTORE PARAMETERS function allows you to restore the currently selected Effect to its factory preset state. When you select this function, you will be prompted to reconsider erasing your changes. If you don’t want to erase your versions, press DONE to exit the menu. Pressing SELECT in response to the displayed query will restore all of the factory preset values to the Effect. Naming your custom Effect EDIT EFFECT NAME allows you to assign a new name, of as many as 13 characters, to your Effect. With EDIT EFFECT NAME highlighted, press SELECT to display the current name with a cursor indicating which character position can be modified. SELECT moves the cursor to a new position. ▲ and ▼ scroll through the available character set. Press DONE to save the new name. Restoring the original Effect name RESTORE EFFECT NAME allows you to restore the original factory name of an Effect, without changing any of your modified parameter settings. When you select this function, the message PRESS SELECT TO RESTORE EFFECT NAME allows you to reconsider erasing your custom name. — If you don’t want to erase your version, press DONE to exit the menu. Pressing SELECT in response to the displayed query will restore the factory preset name. Listening to only the SDP-3 Effect Selecting EFFECT ONLY allows you to listen to only the effects added by the SDP-3 to the currently loaded program. With this function selected, use ▲ and ▼ to turn this function on or off. Front/Back Fader This control allows you to adjust the front/rear balance for the current effect. This control can also be accessed on the remote by pressing and holding the Shift button and using ▲ to move the balance point forward, and ▼ to move it backward. This menu item assigns the status for the remote trigger voltage that appears on pin 5 of the DIN jack on the SDP-3 rear panel. +5VDC is provided for controlling ancillary equipment or functions. This signal can be enabled or disabled for the selected effect. +12VDC is available via an internal jumper. Contact JBL Synthesis Customer Service to perform this change. When the SDP-3 is used with a JBL Synthesis 2.1/5.1 (Stereo/Multi- Channel) system, enabling the remote trigger switches the left and right front speakers into the 5.1 (horn) configuration. Disabling the trigger puts the speakers into 2.1 (tweeter/midrange) configuration.

SDP-3 Digital Surround Processor/Controller System Configuration 35 The PCM Effects are compatible with two-channel input signals (analog or digital). Panorama Panorama extracts the natural ambience from recorded music and moves it outward from the speakers, producing greater width and depth of image and a feeling of enhanced spaciousness. This mode adds no additional sound but expands the existing stereo image. Panorama also works with Dolby Stereo movies, bringing the surround track outward into the room. The location of the front speakers and the listening position are crucial to Panorama’s effectiveness and for best results your system and the SDP-3 together should be set up and calibrated according to the procedure in Chapter 2. The strength of the Panorama effect drops off as you move away from the prime listening position, especially to the sides. Video systems with the main loudspeakers spaced closely on either side of a TV screen will produce a usable effect over a somewhat wider area than set-ups with a large included angle between the speakers.

PCM Effects and Parameters 3
JBL SynthesisPCM Effects and Parameters 36 Football The Football Effect uses a reverberation algorithm, which differs from ambience in that it does not simulate the reflections of specific halls, but emphasizes rich, smooth reverberant decay in small and medium spaces. It works well for simulating a space with a long reverberation time relative to its size, and for simulating the sound of a live sporting event.

In addition, Logic 7 uses intelligent steering to extract wide bandwidth stereo surround channels. If both side and rear speaker pairs are available, signals may be steered between the left side and left rear, or between the right side and right rear. It is also possible for a signal to be steered fully to the rear speakers, with the side surround speakers 6dB lower than the rears to provide subjective rear imaging. Logic 7 contains the re-equalizer feature of the THX Cinema effect, as well as the JBL Synthesis proprietary vocal enhancement feature. The combination of stereo surround information during music and decorrelated effects, with discrete steering to the sides and rears, gives Logic 7 unrivaled performance on matrix encoded films.

The effect is similar to Pro Logic, but includes the features of re-equaliza- tion, timbre matching and decorrelation. The surround channels are monaural, but can be decorrelated. This effect can be reset to use the Logic 7 stereo surrounds with the Stereophonic setting of Surround Mode, although full separation between the sides and the rear speak- ers is not available.
JBL SynthesisPCM Effects and Parameters 40 PCM Effect Parameters 5 SPEAKER ENHANCE simulates 7 speaker playback through a 5 speaker system, providing a heightened sense of spaciousness and envelopment without extra speakers. This enhancement is most notice- able if the surround speakers are positionned directly to the side of the listening position, or if the listening position is located against the rear wall. Note that, although this provides very convincing improvement to a 5 speaker system, it is not a substitute for a properly set up and calibrated 7 speaker system. The difference is most noticeable when the listener is seated to one side or the other of the calibration position. ACADEMY FILTER is provided to recreate the proper tonal balance of older monaural films that were recorded with much narrower and duller frequency response than current films. AUTO AZIMUTH is short for auto azimuth error correction/automatic input balance. Auto Azimuth should be set to ON for films, and OFF for music. When ON, special patented algorithms continually monitor the input signal and adjust both the relative level and time offset of the two channels to keep the dialog properly centered and special effects properly localized. This automatic feature is the reason the unit does not need an input balance control for Dolby Surround decoding. BASS CONTENT allows you to modify the bass content for Mono, Stereo or Binaural recordings. The BINAURAL setting turns the rear level parameter off and activates special low-frequency compensation. This feature is offered specifically for true binaural recordings made with a dummy head. BASS ENHANCE derives stereo bass to provide low frequencies that are noticeably less localizable and more spacious in the playback room. Note that results will vary depending on room acoustics and the low frequency capacity of the surround speakers. Parameter Initial Value Range MAIN LEVEL 10 0-16 ACADEMY FILTER OFF ON, OFF ROLLOFF 3.3kHz 453Hz – 20.0kHz SUBWOOFER LVL +0dB -10dB to +10dB EFFECT LEVEL +00dB -30 to +05dB CUSTOM/TRIGGER ENABLE ENABLE, DISABLE Mono Enhance Mono Enhance takes a monaural soundtrack and sends music and sound effects to the sides and rear through a room simulator mode while keeping the dialog in the center.
SDP-3 Digital Surround Processor/ControllerPCM Effects and Parameters 41 BASS RT (low frequency reverberation time) depends on MID RT and is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for a more natural effect in smaller spaces. CENTER LEVEL adjusts the output level from the center speaker. EFFECT LEVEL adjusts the loudness of the side and rear speakers. When there are no side speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers. In Panorama, this control changes the apparent width of the front soundstage. 0 = ordinary stereo, 62 provides the widest image. FRONT STEERING provides three basic settings which have been developed specifically to optimize center channel signal strength for film and music. The FILM setting has excellent frontal image stability through the whole room during dialog and vocals, while preserving the full width of the front image in the spaces between dialog, and for music without vocals. The front image during vocals is noticeably narrower than with the MUSIC setting, but highly satisfactory nonetheless. The MUSIC setting reproduces sound in all three front speakers when a strongly centered, or mono signal is present. This is an excellent choice for heavily centered pop music such as metal and sounds more natural for broadcast material with a single announcer. OFF sets the center channel level to 4.5dB less than the front left and right speakers, and then leaves the level unchanged as the steering varies. This setting is equivalent to conventional stereo with a slight center fill. HALL SIZE allows you to select room sizes of lengths ranging from 4- 38 meters, depending on the effect selected. INPUT BALANCE allows you to compensate for the occasional source with audible channel imbalance. When selected, screen graphics indicate the relative left/right position. LIVENESS adjusts the amount of recirculation within the effect. Higher values mimic more reflective surfaces in the simulated space and increase the amount of time it takes the sound to decay. At very high values, the decay is audibly less smooth than in the Football and Cathedral Effects, which are more effective at simulating very live spaces.
