BP16 PREAMPLIFIER

Mode (from Analog Mode). Similarly, when re-entering Analog Mode from Digital Mode the previously selected analog input will be automatically re-selected.

See also the DIGITAL-to-ANALOG CONVERTER OPTION section for more information.

HEADPHONE JACK:

There is a quarter inch headphone output jack available on the front panel of the Bryston BP16 Preamplifier. Inserting the headphone jack mutes Preamp Out automatically. You can adjust the volume setting of the headphones by using the volume con- trol on the front of the BP16 Preamplifier. You may also utilize the remote control unit to adjust head- phone volume. The headphones cannot be muted with the remote control unit or the front panel Mute. Only headphones with impedances of greater than 50 ohms should be used.

AUXILIARY IR INPUT:

This mono 1/8” (3mm) phone jack allows a direct connection to equipment whose remote control sys- tem provides an output from their infra-red LED drive circuit. The signal connected to this jack, which is expected to be a 5 volt logic level, should be ≥2.5Vdc and ≤10Vdc. The tip of the phone jack is positive (+) and the ring is negative (-).

LED STATUS INDICATORS:

CLIPPING: This LED (light emitting diode) will flash RED when the output waveform is clipped thus indicating an overload condition.

MUTE: Lights RED to indicate the outputs are muted..

POWER: GREEN indicates normal operation RED indicates Standby

Blinking RED/GREEN a fault or thermal overload problem in the unit.

ANALOGAux2 / DIGITALSelect:

In BP16-DA models: when this LED is illuminated green concurrently with either D1, D2, D3 or d4 LEDs, it indicates that the digital inputs d1 (SPDIF), d2 (SPDIF), d3 (TOSLINK) or d4 (TOSLINK) have been selected.

In BP16 & BP16-P models: when illumi- nated green this LED indicates that the line level analog audio input AUX-2has been

selected.

AUX1, CD, TUNER, TV/SAT VIDEO & RECORD:

One of these input source LEDs will light green to Indicate the active input. In digital mode these LEDs will light RED if the bit stream is either absent or unacceptable.

BALANCE When the left/right signal balance is being shifted one of these LEDs will light to indi- cate which channel is being attenuated.

Balance can be adjusted in 1dB incre- ments to up to -6dB in either direction. Stepping past -6dB in either direction will mute that channel fully and the LED for that channel will turn red.

When both LEDs are on (red), PASS THROUGH mode is indicated. (See “Pass Through Mode” on page 4)

REMOTE POWER CONTROL ~ 12 VOLT TRIGGER CONNECTOR:

Two trigger outputs are provided. A 12Vdc signal is placed across the T1 and C pins (either “C” pin can be used) of the 12V TRIGGERS connector whenever the unit is fully powered up. When the unit goes into standby this voltage is removed.

A 12Vdc signal will be placed across the other pair of 12V TRIGGER out- put pins (T2 and either “C” pin) whenever a cer- tain user programmed input is selected as the source input (see below for programming instructions). When any other input source is
