INTRODUCTION:
Thank you for choosing a Bryston Preamplier. Bryston welcomes any sugges-
ons you may have, or comments regarding the operaon of your amplier. We
consider you, our customer, to be Bryston’s most important resource, and your
opinion is very much appreciated.
SETUP:
The Bryston BP-19 preamp, with remote-control, should be placed where there is
a direct line-of-sight between the hand-held remote and the remote infra-red
sensor eye located on the le side of the pre-amplier’s front panel. If you pur-
chased the BP-19P or BP-19MC, both of which include a Phono secon, avoid
placing the preamplier directly on top of your power amplier. Power ampliers
usually employ large power supplies and the transformers in the power supplies
can cause interference (hum) with the sensive phono secon inside the pre-
amp.
WHITE OLED DISPLAY:
• Currently selected source.
• Current volume level.
• Brightness level adjust.
• Auto Turn O
FULLY DISCRETE FULLY BALANCED CLASS ‘A’ ANALOG CIRCUITS:
The BP-19 analog preamplier is a byproduct of years of R&D that resulted in the
development of an opmized fully discrete opamp buer amplier capable of
delivering a staggeringly low THD+N measurement at or below 0.0006%. The
analog signal path is a FULLY BALANCED DESIGN from input to output, using an
array of very ghtly matched components and a compact circuit design to
achieve the lowest possible noise and superior common mode rejecon.
Connect the pre-amplier’s le and right outputs from either the RCA or Bal-
anced XLR connectors to the appropriate le and right input jacks on your power
amplier. Balanced cables are an advantage if you are using long runs of cable,
(greater than 10 feet), between your preamplier and power amplier. Connect
your CD player, tuner, tape deck, video recorder, or laser disc, etc. to the specic
le/right preamplier inputs. With phono stage equipped models, (BP-19P & BP-
19MC) connect your phono cables to the phono input jacks. If your turntable
leads have a separate ground wire, it may be connected to the ground post adja-
cent to the phono inputs on the rear panel.

The Bryston BP-19 preamp also features two pairs of balanced XLR input jacks.
Many signal sources, including CD-players and separate D/A converters are now
available with Balanced outputs for minimum noise pickup on the cables.
HEADPHONE OUTPUT:
The main outputs, both balanced and single-ended, will be muted when a phone
plug is inserted into the headphone jack. The front panel indicator LED will not
turn red, however, as is does when the outputs are muted via the MUTE toggle
switch or the hand held remote control. The output is a 1/4” (6.35mm) TRS con-
nector where the Tip=Le, Ring=Right, and Sleeve=Ground. Output impedance is
<5Ω.
ANALOG AUDIO INPUTS:
BP-19 preampliers are equipped with four pairs of RCA input connectors: two
pairs of balanced XLR input connectors. Balanced inputs use 3 pin XLR female
connectors with pin 1 being ground, pin 2 as posive signal, and pin 3 as negave
signal. Input sensivity is 1 volt and input impedance is 15K ohms. Single-ended
(or unbalanced) inputs employ gold plated RCA (Phono) jacks. Line input sensiv-
ity is 500mV and input impedance is 50K ohms. See also PHONO EQUALIZATION
MODULES for Phono input details.
ANALOG AUDIO OUTPUTS:
There are two pairs of RCA main outputs one pair xed and one pair variable.
Two pair of balanced outputs, using 3 pin male XLR jacks. One pair xed one pair
variable.

BALANCED OUTPUTS:
As with the input XLR jacks, pin 1 is ground, pin 2 is posive and pin 3 is negave.
These outputs are capable of driving 12 volts into any load of 1K ohms or greater.
Do not use tradional XLR to RCA adapters that
short pins 1 and 3!
SINGLE ENDED OUTPUTS (RCA):
As with unbalanced inputs, these connectors are gold plated RCA (phono) jacks.
They are capable of driving 12 volts into any load of 1K ohms or greater.
BRYSTON BR-4 REMOTE:
You may control many funcons of the
BP-19 with Bryston’s included Remote
ulizing the Preamp buon. The six ana-
log inputs have six buons on the front
panel and Volume, Mute, and Power are
also available.
The Mute buon mutes the main outputs (both balanced and unbalanced) of the
preamplier.
PHONO EQUALIZATION MODULES (OPTIONAL):
Bryston’s oponal phono equalizer circuitry features highly accurate equaliza-
on, extremely low noise and distoron and provides headroom margins su-
cient to prevent overload from any known phono source. If your turntable pro-
vides a separate ground lead system noise may be minimized by connecng it to
the ground post adjacent to the phono inputs on the rear panel.
Moving Magnet Phono Cartridge Input (MM): This is Bryston’s standard RIAA
phono equalizaon stage. It is found in both the “-P” and “-MC” versions of the
BP-19 preamp. Input impedance is 47K ohms and sensivity is 5mV.
Moving Coil Phono Cartridge Input (MC): Moving coil phono cartridges require
much more gain than the more common moving magnet types. To accommodate
moving coil cartridges Bryston oers the BP-19MC pre-amp which include spe-
cially designed, custom-made step-up transformers in addion to Bryston’s
standard RIAA phono equalizaon stage found in the “-P” versions of the BP-19
pre-amp.
Which phono equalizaon stages are engaged is determined by the front panel
display menu “MC Phono / MM Phono”. Please note that it is important that
your phono cartridge is connected to the correct inputs (INPUT 1) in order to
achieve proper performance. Input impedance is 180 ohms and sensivity is
350uV
VISUAL INDICATORS:
The LED on the front panel of the BP-19 lights GREEN when power is on. RED in
standby. Display is white.

GENERAL SPECIFICATIONS
FRONT PANEL CONTROLS: MUTE/NORMAL BUTTON:
Mutes or releases mute at the main outputs, without changing the volume con-
trol seng, each me pushed.
VOLUME CONTROL: Rotary control varies the output level to the ‘MAIN OUT-
PUTS’. The volume control is a digitally controlled aenuated analog step-ladder
design, ensuring long-lasng quiet linear performance. Resoluon is 1/2dB and
le/right channel accuracy of .1dB.
BALANCE CONTROL:
Adjust the le / right balance of audio output by pressing the corresponding
buons on the front panel. Each buon press will aenuate that channel by
0.5dB and increase the opposite channel by 0.5dB (creang a 1dB dierenal.
When either channel is aenuated, the LED above the aected channel will illu-
minate green. When balance is adjusted fully to one side, the opposite channel
will fully mute and the LED above that channel will illuminate red.
LINEAR POWER SUPPLY:
The BP-19 preamplier ulizes a toroidal power transformer.
CONTROL SECTION:
The BP-19 preamplier
can be controlled by
remotely using RS232
or IP when connected
through the RS232 or
SVC Ethernet ports.
TRIGGER INPUT:
The BP-19 can be remotely turned on or placed into standby when receiving DC
voltage into this port.
TRIGGER OUT:
These outputs can be connected to DC trigger inputs of other equipment to mod-
ulate the power state of connected equipment. For example, you can automa-
cally power on an amplier when the BP-19 is powered on.
