PASS THROUGH MODE:
PASS THROUGH mode sets the pre-amp gain to 1 (unity
gain) and locks out the volume & balance controls for
any single analog audio source. For example, if the Front
Left and Front Right outputs of a home theater surround
sound processer were connected to the TV input of the
BP16, and then PASS THROUGH was engaged then wher-
ever TV input is selected the volume and balance con-
trols would be locked at unity gain. If other inputs were
subsequently selected, volume and balance controls
return to normal operation for those other input sources.
Only the TV inputs would be locked at unity gain. PASS
THROUGH mode, therefore, can only be assigned to one
input at a time, but that input can be any one of the analog
audio inputs. The power amplifier stage is not affected
by PASS THROUGH mode. PASS THROUGH mode can
only be set (or reset) by sending the 3 digit code “245” to
the BP16 either from the handheld IR remote control or
via the RS-232 serial data input. See “Sending Codes to
the BP16 via the IR Handheld Remote Control” & “Wired
RS-232 Remote Control”. To reassign PASS THROUGH
mode to a different input source simply select the desired
input and re-send the “245” code to the BP16. To turn
the deactivate PASS THROUGH mode, select the cur-
rent Pass Through input and then send the “245” code to
the BP16. The “245” toggles PASS THROUGH mode on
and off.
DIGITAL-to-ANALOG CONVERTER OPTION:
The BP16-DA comes equipped with stereo Digital-
to-Analog converter (D/A or DAC) module. This
module is also retrofittable to standard BP16 units.
A unique feature of the BP16-DA is its ability to
utilize up to four independent digital sources (two
SPDIF and two TOSLINK). These four digital inputs
can be accessed by selecting D1, D2, D3 and D4
sources with the DAC feature enabled (by pressing
the dIGITAL4Select button on the left end of the
front panel).
Activate the DAC feature by pressing the
dIGITAL4Select (AUX 2) button on the left side
of the front panel (or A/D on the remote). The LED
below the dIGITAL4Select button will turn Green.
Pressing any of the following four buttons will cause
their LEDs to light green, as well, to indicate a PCM
digital source is present and connected properly.
• SPDIF 1 is accessed by selecting D1 on the
front panel or the remote.
• SPDIF 2 is accessed by selecting D2 on the
front panel or the remote.
• Optical 1 is accessed by selecting D3 on the
front panel or the remote.
• Optical 2 is accessed by selecting D4 on the
front panel or the remote.
The source LED’s will turn GREEN when a PCM
digital bit stream is present. If there is no bit stream
available or an incorrect bit stream (non-PCM) the
LED will turn RED.
You may re-select Analog by simply depressing the
dIGITAL4Select (AUX 2) button once more and
the LED will extinguish.
All of the above functions are available from the
hand held remote control as well .
MOVING-MAGNET PHONO STAGE OPTION:
The BP16-P contains a moving magnet phono stage.
The Phono Stage is modular and can be added to the
standard BP16 model later if required by your Bryston
dealer.
Bryston’s MM Phono section features state-of-the-
art accuracy in equalization, extremely low noise and
distortion, and provides headroom margins sufficient
to prevent overload from any known phono source. To
access the Phono section simply plug your left/right
turntable interconnect leads into the left/right AUX-
1/PHONO inputs on the rear panel of the BP16 and
press the AUX-1/PHONO button on the front panel. The
AUX-1/PHONO LED will turn green. If your turntable
provides a separate ground lead, system noise may
be minimized by connecting it to the ground lug in the
center of the rear panel.
