1、BP1 6 For models BP16, BP16-DA it will then turn off within a few seconds. The POWER LED will stay lit green indicating normal operation. CONNECTIONS: WIRED (SERIAL DATA) REMOTE CONTROL: There is one RS-232, one AUX IR input and two 12 volt trigger output connections as well. The RS-232 is bi-direct

CHASSIS GROUND: A chassis ground thumb screw terminal is provided on the rear panel. 12 VOLT TRIGGER CONNECTOR: These 12Vdc control outputs allow the BP16 to exe

LINE LEVEL ANALOG AUDIO INPUTS : The Bryston BP16 Preamplifier comes equipped with 8 pairs of gold plated analog RCA input connectors: TV, CD, AUX-1/PHONO, AUX-2/SPDIF, VIDEO, TUNER, RECORD IN and POWER A

4、MP IN. All have and input impedance of 50K ohms POWER AMP IN is normally connected, internally, to PRE AMP OUT via the CONNECTED/SEPARATE slide switch located on the rear panel. When this switch is in the SEPARATE position, however, any line level audio input can be used at the POWER AMP INPUT jacks

5、 to drive the amplifier. In BP16-DA models the AUX2 (D1/D2) input jacks accept only SPDIF PCM bit streams. They do NOT accept analog audio input signals. In BP16-P models, which are equipped with a moving-magnet phono equalization module, the inputs labeled AUX1/PHONO accept moving mag- net phono ca

6、rtridge inputs. These inputs are NOT line level inputs in the BP16-P and cannot be used as such. LINE LEVEL ANALOG AUDIO OUTPUTS : The Bryston BP16 Preamplifier comes equipped with 3 pairs of gold plated analog RCA jacks for outputs: 2 pairs of PREAMP OUT jacks and 1 pair of RECORD OUT jacks. PREAMP

7、 OUT is normally connected, internally, via the CONNECTED/SEPARATE switch, to POWER AMP IN RECORD OUT output is not affected by volume, balance or mute controls. DIGITAL AUDIO INPUTS: In the BP16-DA model, which contains a stereo D/A converter module, there are 4 digital audio inputs available. Two

8、TOSLINK optical inputs are selected by pressing the D3 (TOSLINK-1) or D4 (TOSLINK-2) buttons on the front panel (when in digital mode) or on the handheld remote. Two SPDIF coaxial inputs can be connected to the BP16-DA using the RCA input jacks labeled D1 and D2. To select these inputs first place t

9、he unit in digital mode by pressing the DIGITAL4Select button on the front panel (or the A/D button on the handheld remote) and then press the D1 or D2 button on the front panel or on the remote). When the green LED above the font panel DIGITAL4SELECT switch button in ON concur- rently with either t

10、he D1 (cd), D2 (tuner), D3 (tv) or D4 (vIdeO) LEDs, then digital mode is engaged.

Similarly, when re-e

11、ntering 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 P

12、reamplifier. 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

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 c

14、ircuit. 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 (-).

POWER: GREEN indicates normal operation RED indicates Standby Blinking RED/GREEN a fault or thermal overload problem in the unit.

In BP16 restore defaults PASS THROUGH MODE: PASS THROUGH mode sets the pre-amp gain to 1 (unity gain) and locks out the volume & bal

17、ance 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 wou

18、ld 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 ca

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 th

20、e 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 sen

21、d 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

22、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

23、 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 c

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 remot

25、e. The source LEDs 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 t

26、he 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. Brystons MM Phono section f

27、eatures 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 inpu

28、ts 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. BP16 SPECIFICATIONS: Frequen
