please contact your dealer, distributor or  
Bel Canto Design.  
IMPORTANT: Save all packing  
materials as the packing is spe-

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.  
Pin 1 Ground  
Pin 2 Input +  
Pin 3 Input -  
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  
eVo power amplifier.
