PRODUCT DESCRIPTION – The Shenandoah
®
Compak 300 series of acoustic amps delivers warm, rich tone
and phenomenal output in surprisingly compact, lightweight cabinets. Each model produces 175 watts as a combo
and 300 watts with an 8 ohm extension cabinet. The amplier is congured as a 2 channel – 3 input platform and
each channel is equipped with a ¼” unbalanced line input. Channel 2 offers an XLR balanced microphone input
(with phantom power) as well. The 2 inputs on Channel 2 are summed (mixed) together at a 1:1 ratio, so they can
be used simultaneously. Each channel then passes through independent 3 band equalizers with a sweepable
midrange frequency. Equalization centers were carefully selected for use with acoustic instruments. Each channel
also contains individual send controls to the on-board 24-bit 15 program digital effects circuit. The back panel
contains 3 direct outputs with ground lift switch, an effects loop, auxiliary input, headphone jack, effects cancel jack,
and 2-1/4” speaker jacks.
