Thank you for purchasing the Bel Canto Design eVo2i. Your eVo2i is designed to main-

tain very high value, setting the benchmark for design, quality and sonic performance

while maintaining our heritage of musicality and realism.

eVo2i

Two-Channel Integrated Audio Amplifier

™

The power supply on the eVo2i is preset

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 integrated amplifier, like any electri-

cal component, can be dangerous and

cause injury unless correct handling pro-

cedures are observed and used. Before

powering this preamplifier it is neces-

sary to read and follow proper setup

and procedures.

Unpacking

Power Connection

eVo2i box contents include the following:

1 (one) - eVo2i Integrated Amplifier

1 (one) - eVo2i User’s Guide

1 (one) - Power cord

1 (one) - Remote Control

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 packaging becomes lost or dam-

aged, please contact your dealer, dis-

tributor or Bel Canto before attempting

to transport your unit.

Because the eVo2i runs cool it can be

placed in many system locations without

compromise. We do not recommend

placing weights or other objects directly

on the eVo2i. This may mar or scratch

the chassis finish. Do not use harsh

chemicals when cleaning the outside of

your eVo2i.

Single Ended RCA and Balanced XLR

connectors are available. XLR jacks

allow balanced hookup using the stan-

dard pin configuration:

Pin 1 Ground

Pin 2 Input +

Pin 3 Input -

• The elegant simplicity of the signal path

and gain stage allows the eVo2i to pre-

serve audio signal quality. Audio Grade

decoupling capacitors and resistors, star

grounding and careful signal routing insure

that low-level signals are preserved.

• Input processing provides one balanced

XLR connection, three RCA jack connec-

tions and Tape In. Tape Output is an RCA

output with an active audio-grade buffer to

isolate the internal signal bus from the tape

output. Line out RCA connection offers flexi-

bility of use with a sub woofer, external

amplifier for bi-amping or outboard signal

processor.

• The volume control is a precision analog

stepped attenuator controlled by a micro-

controller. This device provides extremely

low noise and distortion coupled with high

accuracy. The sonic quality is superior to

the best potentiometers and insures no

wear.

• High efficiency Digital Power Processing

eVo power amplifier.

• Efficiency >90% insures cool operation.

• THD and IMD <0.05%

• Damping Factor >100

• High thermal stability in all stages

• Fully regulated, low noise supplies for all

analog stages

• Soft clipping with uncompromised low

level distortion performance

• Ultra-low power dissipation for ‘green’

amplification

• Protection circuitry outside signal path

• Programmable features allow you to dis-

able (except TAPE), name and set volume

for listening and soft mute levels for ALL

inputs individually

• The eVo2i powers on in Soft Mute Mode.

Soft Mute Mode is a fully adjustable setting

that also can be selected as a muting

option during regular listening.

Placement and Initial Setup

Design Features

IMPORTANT: Make all connections before powering your unit.

The eVo2i’s sonic performance will start

to stabilize after 100 hours of continu-

ous power up.

Volume Up:

Increases the output level in 0.5 Decibel

(dB) steps from 0.0 to 100.0.

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.

The eVo2i starts up in Soft Mute. This

level is 20dB below the displayed vol-

ume 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

Inputs 1 to 4

Standard line level inputs. Input 1 is bal-

anced and may be used with unbal-

anced sources using an RCA to XLR

adapter.

Line Out is a buffered preamplifier out-

put which tracks the volume setting on

the front panel. This can be used to

drive the line level input on a subwoofer,

for example.

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.

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 -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.

Setup Menu Options

Loudspeaker Connection

Connect loudspeakers to the outputs of the

eVo amplifier using the 5-way binding posts

located the rear of the amplifier. The red or

black center plug in the output post can be

removed for use with banana type connec-

tors (all non CE countries). Do not connect

speaker terminals to a ground connection.

The Anti-Phase operation of the outputs

would result in one of the red (positive) out-

puts being connected to ground and cause

the amplifier to go into protection mode and

shut itself off.

Make certain that no connection from the

output terminals is made to a chassis or

earth ground.

B) 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 eVo2i.

Press ENTER to save your configuration

and exit this menu mode.

C) 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.
