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.
Power Connection
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.
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.
Warning!
Do not connect power to this
preamplifier yet!

Placement and Initial Setup
Because the eVo2i runs cool it can be
Single Ended RCA and Balanced XLR
connectors are available. XLR jacks
allow balanced hookup using the stan-
dard pin configuration:
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.

IMPORTANT: Make all connections before powering your unit.
Design Features
• The elegant simplicity of the signal path
• Efficiency >90% insures cool operation.
• THD and IMD <0.05%
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.
• Damping Factor >100
• High thermal stability in all stages
• Fully regulated, low noise supplies for all
analog stages
• 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.
• 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 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.
• 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.
• High efficiency Digital Power Processing
