Optional Modules; Moving Magnet Phono; Digital To Analog Converter (Dac); Remote Control - Bryston BP-17 cubed series Owner's Manual

Optional Modules

The BP-17³ may be optionally equipped with a
moving magnet phono input and/or a digital to
analog converter. These may be fitted at the time
of ordering or retrofit at a later time by a certified
technician.

Moving Magnet Phono

The optional MM Phono input occupies INPUT 2, so
input 2 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.

Digital to Analog Converter (DAC)

The DAC is a high quality module that shares INPUT
1. That is, INPUT 1 can still operate as a standard
analog stereo input pair, but it can also operate as
two separate S/PDIF digital coaxial inputs. When
the DAC module is installed, digital inputs 1 and 2
(TOSLINK optical connectors) are also connected
and activated. In total, when the DAC is installed, 4
digital inputs are available for use. To select a DAC
input, press the DIGITAL
front panel or the BR-2 remote control, then press
the button that corresponds with the input you wish
to hear. The DAC can receive PCM digital audio at
44.1kHz, 48kHz, 88.2kHz, or 96kHz sampling rates
and 16 or 24 bit resolution. When a digital input is
activated, the LED above 1 will illuminate green. The
LED above the selected digital input will illuminate
red when the input is selected and green when it
is selected locked to a compatible digital audio
source. Each input will remember whether analog
or digital was last selected.

Remote Control

The BP-17³ can be controlled and monitored
through RS232 and IR.

Serial Protocol

The BP-17³ can receive commands, send
acknowledgment of commands received, and can
be queried for certain statuses.

Using the DB9 female connector at the rear of the
unit, the BP17 can receive commands via a straight-
through cable at 9600 baud, 8 data bits, no parity
and 1 stop bit (9600,8,N,1). Valid commands will
return the ">" character indicating that the unit
is ready to receive a new command. An invalid
command will return the "!" character.
These serial data commands are as follows:
