SSP 7.1 Front Panel Features
Configuration port — The SSP 7.1 can be configured using Extron Simple Instruction
Set (SIS ) commands through this 2.5 mm Tip Ring Sleeve (TRS) mini jack plug (or
™ ™
through the 3-pole captive screw connector on the rear panel). For more information
about SIS commands, see page
NOTE: Both the rear panel RS-232 port and the front panel configuration port can
be used at the same time. Neither has precedence. The SSP 7.1 responds to
commands in the order received.
Input source format indicator — The bank of four LEDs lights to identify the format
of the audio input.
о Dolby Digital ( D): Dolby Digital 2/0, Dolby Digital 2/0 Surround, Dolby Digital 5.1,
or Dolby Digital Surround EX.
о
DTS: DTS 2-Channel, DTS Digital Surround, DTS 96/24, DTS-ES Matrix 6.1,
DTS 96/24 ES Matrix 6.1, or DTS-ES Discrete 6.1.
о
PCM: 2-channel uncompressed digital source format.
NOTES: A digital signal that does not have a supported sampling rate or is
compressed PCM is considered an unrecognized signal and is muted.
When a DVD player is paused during playback, the SSP 7.1 may or may
not continue to receive source format information from the DVD player.
Some players continue to send the same source format information in
a loop, allowing the SSP 7.1 to retain the previous settings. Other DVD
players completely disconnect the signal from the SSP 7.1 (unlocked
state), so that the active input blinks as if there is no connection present.
The remainder of DVD players change the source output to PCM without
an actual signal being sent (digital silence). During digital silence, the
PCM LED lights but the 2-CH source LED does not.
о
2-Channel (2-CH):
• Any source coming through analog input #5.
•
If a PCM digital signal is present on any of the digital inputs, both the PCM and
the 2-CH LEDs light.
•
If a Dolby Digital 2/0 or Dolby Digital 2/0 Surround source is present, both the
D and the 2-CH LEDs light.
•
If a DTS 2-Channel source format is present, both the DTS and 2-CH LEDs light.
