on standby. If neither this LED nor any other LED on the front panel is illuminated then there is no power entering the unit or the internal fuse is blown. See also Remote Trigger section.
8:INPUT SIGNAL LED INDICATORS: There are 8 LEDs to indicated which input has been selected. The LED will light green when a PCM signal is present at the selected input, and red for any other signal present condition, including AC3 multi-channel signals.
9:ANALOG AUDIO OUTPUTS: The BDA-1 is supplied with one pair of gold plated RCA (phono) jacks for unbalanced (single-ended) outputs as well as one pair of fully balanced outputs on XLR male connectors. All connectors are gold plated and all output signals are fully buffered by Bryston’s discrete analog audio amplifier stages.
10:SPDIF OUTPUT: The signal present at the SPDIF output connector is the same signal that is selected as an input source. This signal is unaltered except for USB input sig- nals.
11:REMOTE TRIGGER INPUT: The BDA-1 is supplied with a Trigger input put to facilitate remote hard wired on/off control. A two pin socket mates with the CO110A-11102 bare-wire terminal block connector supplied with your BDA-1 (see illustation below-left). Supplying a DC control voltage between 3 and 12 volts (at greater than or equal to approximately 3mA) will allow you to remotely power your BDA-1 on or off. The the Remote Trigger input takes precedence over the front panel push-button switch. If a valid control voltage is initially applied to the trigger input when the BDA-1 is already powered on it may be necessary to toggle the unit OFF-and-ON once, via the Trigger input, to establish the precedence of the trigger input signal over the front panel power switch.

FIRMWARE UPDATES
BDA-1 firmware updates will periodically be available from Bryston dealers or from Bryston Ltd. directly. These firmware updates will be supplied as an executable file
(program) which, when executed on your PC, will search for available serial ports on your computer and then search for the BDA-1 before uploading and automatically installing the new firmware in your BDA-1.
1)If the BDA-1 is ON, place it in standby by pressing the POWER button either on the front panel or on the remote control. When the LED above the POWER button lights red, the BDA-1 is in standby.
2)Connect a suitable RS232 cable between your PC (sorry, but MAC’s are not supported at this time) and the BDA-1. In most cases (depending on your
