front panel is illuminated then there is no power entering 

the unit or the internal fuse is blown.

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.

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 (

. 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
