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.

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
