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.

Unpacking your PRe2/P

Carefully unpack each piece and check

for shipping damage. If there is any

damage, or if anything is missing,

please contact your dealer, distributor or

Bel Canto Design.

IMPORTANT: Save all packing

materials as the packing is spe-

cially designed to protect the unit during

transportation or shipping. If the packag-

ing becomes lost or damaged, please

contact your dealer, distributor or Bel

Canto before attempting to transport

your unit.

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

Placement and Initial Setup

Design Features

IMPORTANT: Make all connections before powering your unit.

The PRe2/P’s sonic performance will

start to stabilize after 100 hours of con-

tinuous power up.

Volume Up:

Increases the output level in 0.5 Decibel

(dB) steps from 0 to 120.

Volume Down:

Decreases the output level.

Balance Left: (available from the

remote only)

Shifts balance left in 0.5dB steps. It is

also used to scroll left in the setup menu.

Balance Right: (available from the

remote only)

Shifts balance right in 0.5dB steps. It is

also used to scroll right in the setup

menu.

MUTE:

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.

ENTER:

This control button is pressed and held

on the front panel or pressed 7 times on

the remote to enter into the menu setting

functions described below. It is also used

to enter into specific modes within the

menu system.

MAIN:

Cycles through the main inputs. It is also

used to scroll to the left in the setup

menu.

LOOP: (available from the remote only)

This is used to cycle through the inputs.

INPUT:

On the remote the Numbered Buttons (1-

5) allow you to select between the 1st

five active inputs. From the remote, you

can cycle through inputs using the LOOP

button. From the front panel, you can

cycle through inputs by pressing the

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.

TAPE:

On both the remote and the front panel,

the TAPE button will cycle through the

input to be routed to the Tape Out jacks

and a Tape Out Off setting.

It is also used to scroll to the right in the

setup menu.

STANDBY:

When in STANDBY mode the red LED is

engaged, the display is off and the out-

puts are muted. The unit remains

warmed up and ready for use when

taken out of standby.

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

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.

PRe2/P Setup and Options

C) SAVE CONFIG ? Menu

This is used to Save the Setup Changes

made in the menu system.

Be sure to use this to store the changes

when you are satisfied with your setup.

Use the UP/DOWN keys to toggle

between YES or NO and save the menu

settings.

Saving the settings will insure that your

changes are active even if power is

removed from the Pre2/P.

Press ENTER to save your configuration

and exit this menu mode.

D) ERASE CONFIG ? Menu

This is used to Restore the Factory

Default menu settings.

Use the UP/DOWN keys to toggle to

YES or NO.

Press ENTER to erase your configuration

and restore the factory settings.

Warning: This operation resets all of

your custom settings.

PRe2P Phono Stage Setup

A*) PRe2P Phono Configuration

This menu is used for setting up the

Phono Section of the PRe2P. It is the first

active menu only in the PRE2P and is not

used in the PRe2.

1) Mono/Stereo mode is set by pressing

ENTER and using the UP/DOWN button

to select the mode.

2) Resistive Input loading. This may be

adjusted by pressing ENTER and scroll-

ing through the loading options.

3) Capacitive Input loading may be set

the same way.

4) Gain is set between 40 dB at 1KHz

and 60 dB at 1 KHz. We suggest that

you use 60 dB for cartridges with out-

puts rated below 1-2 mV.

Press ENTER to exit each menu mode

and use the SAVE CONFIG ? menu to

save your setup.
