Setting the Optical Audio Input Assignment
i. Enter the main menu by pressing on one of the menu
buttons on the SP1 front panel. Move the cursor to "OS".
Hit 'Select' - You are now in the 'Other Settings'
(Optical/THX) Menu.
ii. Move the cursor to the Optical Input (OPT1 or OPT2) you
want to change the input assignment for. Hit 'Select'.
iii. Now you can assign the optical input to any one of the 6
inputs selectors. Doing this will override the digital coax
connector on that input. Hit 'Select' when finished.
NOTE: On the pro model, 'AES' will show up in the 'Other Settings'
Menu (instead of OPT1 and OPT2), to setup the AES/EBU input
assignment.
6. Tape/Recording Outputs
The SP1 provides two analog outputs for the TAPE and VCR
sources. The front panel selected input signal is always routed
to these tape outputs, except when TAPE or VCR is selected.
In those cases the appropriate output is automatically muted
to prevent feedback.
7. Remote 12V Trigger Outputs
Two trigger outputs are provided.The output labeled
"ON/OFF" provides a 12V voltage level whenever the unit is
fully powered up. When the unit goes into standby, the level
is 0 Volts.
The output labeled "AUX" is programmable from the LCD
menu as described below.This means that the terminal
supplies the 12-Volt signal only when you switch to certain,
specified inputs.
The Centre (Common or Ground) terminal is always used
with the "ON/OFF" or "AUX" terminals to complete the circuit
loop. The 12-Volt connector will accept
wire ends, inserted into the square holes provided, and the
adjacent screws carefully tightened to hold them in place.
These can be used to control any Bryston Power amplifier
and many other components such as motorized screens and
drapes. Be sure to determine what type of trigger signal the
selected components requires and what function will be
enabled by the trigger signal's voltage.
