Welcome
Thank you for your purchase of a Bryston
Active Loudspeaker System! Our class leading
loudspeakers and ultra high performance DSP
crossover platform combine with your choice
of Bryston amplification to form a unique high
performance playback system through which you
can hear details you never thought possible. We
welcome your feedback and hope you enjoy your
new Bryston Active Loudspeakers for many years to
come.
Description
Fully active loudspeakers dispense with passive
crossovers that are built into conventional
loudspeakers in favor of crossovers inserted before
amplification is applied. The benefits are many
including increased flexibility with filter shapes,
the ability to make fine-grained adjustments
which result in improved on and off axis response
(these are often competing objectives in passive
loudspeakers), direct coupling of the loudspeaker
to the driver which avoids losses inherent in passive
crossovers and more. Bryston Active Loudspeakers
combine decades of research into acoustics,
electronics, amplification as well as state of the
art components to recreate your recordings with
stunning realism. The BAX-1 Active DSP Crossover is
a core component of this system.
The BAX-1 is a state of the art DSP crossover that
has been specially programmed at the factory
for compatibility with your specific model of
Bryston Active Loudspeakers. It is comprised of
two channels of analog to digital conversion which
convert incoming full range analog audio from your
preamplifier to an equivalent digital audio signal
sampled at 96kHz and decimated to 24 bits. This
signal passes to a high powered DSP core which
performs the 3-way crossover function for each
channel and any user selected filters desired for
altering the bass response of the loudspeakers
in the room. Three bands of audio per channel
are then passed to 6 digital to analog converters
4
followed by fully discrete balanced analog outputs
which in turn feed 3 amplifier channels per
loudspeaker. The BAX-1 only accepts balanced input
and provides balanced output. No single ended
audio connections are available. If you require
single ended connections, XLR to RCA adapters can
be used.
The system can be user controlled through a simple
and intuitive web-application for setup. Network
connection is required for those who desire to
tailor the bass response of the loudspeaker to the
room and for firmware updates but is not otherwise
necessary.

Shipping Box and Packing Material
Please keep the original shipping box and all
packing material. This will ensure the BAX-1 is
protected in future transport. In the unlikely event
you have a problem and must return it for service,
you must use the proper packing material. Ship
the BAX-1 only in the original packing material
as the unit is not insurable by carriers otherwise.
Replacement packing materials consisting of a
shipping carton with plastic foam inserts is available
from Bryston for a small fee.
Installation
Ventilation
The BAX-1 is a cool-running line level component.
It generates far less heat than amplifiers and many
other components. It can be safely placed inside
furniture or an equipment rack. However, it should
