Because the eVo2i runs cool it can beplaced in many system locations withoutcompromise. We do not recommendplacing weights or other objects directlyon the eVo2i. This may mar or scratchthe chassis finish. Do not use harshchemicals when cleaning the outside ofyour eVo2i.

Single Ended RCA and Balanced XLRconnectors are available. XLR jacksallow balanced hookup using the stan-dard pin configuration:

Pin 1 GroundPin 2 Input +Pin 3 Input -

• The elegant simplicity of the signal pathand gain stage allows the eVo2i to pre-serve audio signal quality. Audio Gradedecoupling capacitors and resistors, stargrounding and careful signal routing insurethat low-level signals are preserved.

• Input processing provides one balancedXLR connection, three RCA jack connec-tions and Tape In. Tape Output is an RCAoutput with an active audio-grade buffer toisolate the internal signal bus from the tapeoutput. Line out RCA connection offers flexi-bility of use with a sub woofer, externalamplifier for bi-amping or outboard signalprocessor.

• The volume control is a precision analogstepped attenuator controlled by a micro-controller. This device provides extremelylow noise and distortion coupled with highaccuracy. The sonic quality is superior tothe best potentiometers and insures nowear.

• High efficiency Digital Power ProcessingeVo 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 allanalog stages

• Soft clipping with uncompromised lowlevel 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 volumefor listening and soft mute levels for ALLinputs individually

• The eVo2i powers on in Soft Mute Mode.Soft Mute Mode is a fully adjustable settingthat also can be selected as a mutingoption during regular listening.
