Input Name
The name that is shown on the display and logged when a particular format is selected can be set by the user. Type
a meaningful name for the format in the Input Name field.
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.
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.
CH 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 these inputs are 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 equalizations curves. Four EQ sets are available. Each set
allows full equalization of all the audio channels. Choose which equalization set to use for this format.
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.
