first by compatibility with desired audio formats,
then by order of sound quality. Source component
permitting, multiple digital connections can be
made between the source component and BR-20.

Player
When the BR-20 is receiving valid digital audio, the
LOCK LED will light green on the front panel.
Optional Modules
The BR-20 may be optionally equipped with a
moving magnet phono input and/or an HDMI input
/ output module . These may be fitted at the time of
ordering or retrofit at a later time.
Moving Magnet Phono
The optional MM Phono input occupies RCA 1, so
RCA 1 can no longer be used for line level source
components such as tuners, CD players, etc. This
high quality phono stage is the same circuit found in
our stand alone BP-2 MM.
HDMI
The HDMI module features 4 inputs and 1 output.
Each input is 18 gbps capable and can therefore
pass 4K video and HDR. The HDMI input can also
receive SACD DSD64 audio from a suitably equipped
universal disc player which will be natively decoded
by the DAC portion of the BR-20. The HDMI output
includes hardware support for eARC, but at the time
of this edition, is not yet enabled in software. We
expect to enable this feature in a future firmware
update.

Remote Control
The BR-20 can be controlled and monitored through
IP, RS232 and IR.
Serial Protocol
The BR-20 can receive commands, send
acknowledgment of commands received, and can
be queried for certain statuses.
Using the mini TRS female connector at the rear of
the unit, the BR-20 can receive commands via a null
modem cable at 9600 baud, 8 data bits, no parity
and 1 stop bit (9600,8,N,1). Valid commands will be
echoed back to the console. Invalid commands will
return ??.
Each valid BR-20 serial command must begin with
the three characters #10 and end with the carriage
return (ASCII code 13).
For example #10HELP<cr>
A list of valid commands can be retrieved by issuing
the #10HELP command from the terminal. , in
addition each command can display its own help
describing the list of available options by putting
the ? as the command option at the end of the
command string. For example #10LIST? will list all
available options xx for the #10LISTxx command.
The same commands are available from the Web
User Interface (WebUI) with the slightly different
format: the start character # must be replaced with
%23 and each command must be ended by a dot
(instead of carriage return). For example:
%2310HELP.
IR Control
You may control may functions the BR-20 with a
traditional infrared remote control such as Bryston's
included Remote 20.
Each of the ten buttons in the INPUT area of the
remote can be assigned to your choice of digital
input using the basic web UI or the front panel
menu. The four analog inputs have four buttons on
