PRe2 & PRe2P
Two-Channel Analog
Pre-Amplifier
™

The power supply on the PRe2/P is pre-
set for the proper national voltage. The
power cable should have the correct
plug for your local power system. If you
believe this to not be true, please con-
tact your dealer immediately.
Warning!
Do not connect power to this
preamplifier yet!
This preamplifier, like any electrical com-
ponent, can be dangerous and cause
injury unless correct handling proce-
dures are observed and used. Before
powering this preamplifier it is neces-
sary to read and follow proper setup
and procedures.

Because the PRe2/P runs cool it can be
placed in many system locations without
compromise. We do not recommend
placing weights or other objects directly
on the PRe2/P. This may mar or scratch
the chassis finish. Do not use harsh
chemicals when cleaning the outside of
your PRe2/P.
Single Ended RCA and Balanced XLR
connectors are available. XLR jacks
allow balanced hookup using the stan-
dard North American pin configuration:
Pin 1 Ground
Pin 2 Input +
Pin 3 Input -
The Bel Canto PRe2/P represents a pow-
erful statement in high performance
audio control preamplifiers. Its superb
audio performance and transparency ren-
ders it a modern standard in control and
RIAA preamplifier design:
• All analog, low noise, low distortion
architecture for controlling up to seven
2-channel inputs including 1-balanced
input
• Fully balanced XLR outputs for optimum
interface to the power amplifier
• Programmable options for all inputs:
Function (stereo, disable), Name, Main
level, and Soft Mute level
• 4-layer PC board design for superior
signal routing, grounding and power
supply routing
• Latest generation of active audio
buffers, level controls and output drivers
provide superb measured and subjec-
tive audio quality
• Independent digital and analog trans-
formers and multi-stage power supplies
for precise power of sensitive analog cir-
cuitry
• Precision resistors and no capacitors in
the audio signal path
• Ultra low noise second stage regulation
for the analog amplifier sections
• Ultra-low noise active amplification for
RIAA Phono Stage (PRe2P)
• Front panel and remote selectable
Phono stage gain, resistive and capaci-
tive loading and Mono/Stereo opera-
tion (PRe2P)
• Digitally controlled analog
volume control for optimum signal archi-
tecture and no-compromise gain and
balance control

The PRe2/P starts up in Soft Mute. This
level is 40 units (20dB) below the dis-
played volume level. When MUTE is first
pressed it goes to the Soft state, pressing
MUTE again within 3 seconds will fully
MUTE the outputs.

MAIN button. When switching between
inputs, the PRe2/P will quickly ramp
down the volume, switch inputs, then
quickly ramp back up to the pro-
grammed volume setting.

PRe2/P MENU FUNCTIONS
A) INPUTS CONFIGURATION Menu
This menu is used to customize the input
options.
It is used to set:
1) Input Function
2) Input Name
3) Initial Volume level
4) Soft Mute level
1) The first level of this menu is used to set
the INPUT FUNCTION. The options are
Stereo or Disabled.
Change these settings by scrolling left or
right to the desired input and pressing
ENTER to change the setting. Use the
UP/DOWN keys to scroll through the set-
ting options. Disable unused inputs.
Press ENTER to exit this menu mode.
2) The second level of this menu is used
for changing the Name of a given input.
To change an input name press ENTER
and you will see an under-bar indicator
for each of the 8 characters that can be
used for naming the input. Scroll the indi-
cator left or right using the LEFT/RIGHT
keys and use the UP/DOWN keys to
scroll through capital and lower case let-
ter, numbers 0-9 and a SPACE.
You can use the SPACE to separate words
and numbers or to center short names like
CD. Press Enter to exit this menu mode.
3) The third menu level is used to set the
Initial Volume level.
Press ENTER and use the UP/DOWN
keys to set the default level when coming
out of STANDBY. Press ENTER to exit this
menu mode
.
4) The fourth menu level is used to set the
Soft Mute Level.
This is preset to -40 units or -20 dB. This is
generally a good soft mute level.
If you wish to change this for a given
input then press ENTER and use the
UP/DOWN keys to scroll to a different
setting.
Press Enter to exit this menu mode.
B) OFFSETS CONFIGURATION
Menu
This menu is used to set the 0dB gain
setting for the Pre2/P.
This is important for optimizing the gain
control range for systems with different
amplifier gain, input levels and loud-
speaker efficiencies.
For example: if you find that the volume
level is too loud even if the indicated vol-
ume is at or near 0 then you need to
increase the 0dB gain setting from the
default of 100 to 110, 120 or higher.
This will allow you to set the volume
level lower before reaching the 0 limit
on the display.
To change this setting, press ENTER and
use the UP/DOWN controls to set the
desired number.
Press ENTER to exit this menu mode.

adjusted by pressing ENTER and scroll-
ing through the loading options.
3) Capacitive Input loading may be set
