Preset Level
If preset is enabled, the JSD-100 will adjust the main fader level to the preset level set here. If the preset is not
enabled, the JSD-100 will adjust the main fader to the level last used on this format. With a preset, levels can be
adjusted during normal operation using the front panel fader, but will return to the preset level when the format is
selected again. Without the preset, the level will return to the level that particular format was last adjusted to.
NOTE that presets can only be changed through the GUI. This feature prevents unauthorized people from changing
the presets. You may want to not enable presets to allow local personnel to adjust playback levels. When a preset
is not enabled, the main fader level will return to the last level used on that format.
Input Delay
A separate input delay setting is available for each format to enable precise synchronization of the audio with the
projected image.
Rear Surround Source
The audio source for the rear surround speakers can be configured independently for each format. These setting
provide a source of audio for the rear surround speakers when playing 7.1DS audio as well as when playing sources
that do not have discrete channels to drive these speakers. (See Section 4.4 for details on soundfield
configurations). These sources are further described in the table below.
Rear Surround Source Description
Ls/Rs The rear surround speakers are driven by the surround speakers. Lrs is driven by Ls. Rrs
is driven by Rs. This setting results in an L-shaped surround where the left surround
continues down the left wall to the left side of the rear wall of the auditorium. This
often the choice for 5.1 content.
EX Both rear surround speakers are driven with 0.5 (Ls+Rs). This is similar to a derived
center speaker.
AES 7/8 or
Analog 7/8 The rear surround speakers are driven by discrete channels 7 and 8 from the digital 16
channel or analog 8 channel source. Channel 7 drives Lrs. Channel 8 drives Rrs.
AES 11/12 The rear surround speakers are driven by AES channels 11 and 12 from the 16 channel
digital input. Note that tis only available if the optional DI-80 board is installed in the
JSD-100. AES 11 drives Lrs. AES 12 drives Rrs.
EQ Set
The JSD-100 allows different formats to use different equalization curves. Four EQ sets are
available. Each EQ set holds all the settings available on the Equalizer tab. These controls
include the graphic equalizer settings and channel output level, but do not include the LFE
parametric equalizer or controls in the crossover. The EQ set portion of this tab shows the
currently selected EQ set and has four buttons to select other EQ sets. The name in the
currently selected field can be changed by the user to give a meaningful name to the EQ set.
These names are saved in the JSD-100 and will be shown the next time the GUI connects to the
JSD-100. The currently selected equalizer set is always visible on the status bar at the bottom
of the GUI window
Decode Options
Two channel sources can be decoded out to several channels. These options are available on digital and analog
two channel formats, such as COAX1, COAX2, TOSLINK, NON/SYNC, and AUX.
Dolby Digital® (AC-3) alternative content can only be played if a DI-84 board is present and Active Matrix is
selected. Attempting to play AC-3 material without the DI-84 board will mute the audio.
