PRODUCT DESCRIPTION

 – The 

Shenandoah™ Acoustic 100

 is confi gured as a 2 channel – 4 input 100 

watt acoustic instrument amplifi er. Each channel is equipped with both a ¼” unbalanced line input and an XLR  
balanced microphone input (with phantom power). The 2 inputs on each channel are summed (mixed) together at a 
1:1 ratio. 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 Alesis® 15 program digital effects circuit. The channel signals are then 
summed together, mixed with the digital effects return and passed on to the internal 100 watt power amplifi er. The 
back panel contains 3 direct balanced outputs with ground lift switch, 3 unbalanced line outputs, an effects loop,  
effects cancel jack, fan on/off switch and 2-1/4” speaker jacks.
