1. Power Button
Press this button to toggle the BAX-1 on or into
standby mode.
Unlit BAX-1 is not receiving power. Plug unit into
AC mains power.
Red Plugged into AC Mains but in standby
mode.
Green or BAX-1 is on and operational.
Blue
Blinking Secondary power supply failure. Contact
Red Bryston technical support.
2. Audio Channel Indicators
The left and right channels both feature LEDs
which indicate the incoming audio status of
each channel.
Unlit BAX-1 is not receiving audio to the
indicated channel
Green or BAX-1 is receiving audio at the indicated
Blue channel
Blinking Audio received is too loud to be processed
Orange without distortion. Reduce preamplifier
volume.

3. Channel Input Output
The BAX-1 includes Left and Right channel
input and output. Analog audio is received
through a balanced audio interconnect from a
stereo preamplifier to the left and right channel
inputs respectively. The internal DSP divides
and processes that signal into 3 bands - low,
mid and high to drive the bass, midrange, and
high frequency amplifier channels respectively.

Preamplifiers and amplifiers that do not feature
balanced audio connections can be connected
to the BAX-1 by using commonly available XLR
to RCA adapters.
Each channel also includes a trigger out jack
on a 'mono' 3.5mm jack which can be used
to trigger the power state of compatible
downstream amplifiers. The tip is +12V and
sleeve is GND. When the BAX-1 is powered on
either by actuating the front power button or
through the trigger input, voltage is applied to
the trigger outputs.
4. RS232 Input
The BAX-1 can be controlled via two-way RS232
using a connector terminated by a 3.5mm TRS
'stereo mini plug' . Terminate the plug as follows:
Tip: Transmit
Ring: Receive
Sleeve: Ground
5. USB Control Input
USB is provided for diagnostic information by
Bryston technicians.
6. Status LED
LED lights to indicate the following status:
Red: Standby
Amber: Starting up Blinking Amber: Updating firmware
Blue: Self programing. Do not power off
7. Ethernet Input
Ethernet connectivity is provided for user access
to a web based interface which is useful for
firmware updates and control over the internal
DSP. Discrete commands can also be sent by
custom integration systems. See page 10 for
