PRODUCT DESCRIPTION
150/200 watt acoustic instrument amplifier. 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 24-bit 15 program digital effects circuit. The channel signals are
then summed together, mixed with the digital effects return and passed on to the internal power amplifier. The back
panel contains 3 direct balanced outputs with ground lift switch, 3 unbalanced line outputs, an effects loop, effects
cancel jack, and two-1/4" speaker jacks.

    FRONT PANEL INPUTS – The Shenandoah™ Acoustic 150LT is equipped with 2 types of input jacks. The ¼” input is unbalanced and “line level” with a usable sensitivity from 100 mV to 1.6 volt. The input impedance is 270k ohms. The ¼” input will also accept most active balanced line sources.

    ACTIVE EQUALIZATION – The Shenandoah™ 150LT offers a 3 band (with sweepable mid) active equalizer for each channel. These equalizers, similar to those found on professional sound consoles, are very useful tools when used correctly. LOW FREQUENCY EQ - The corner frequency of the low frequency section is 125 Hz, shelving curve. This fre- quency is particularly handy when dealing with low frequency feedback from a big dreadnaught guitar.
  • Page 4 EFFECTS LOOP —A serial effects loop is provided so an out-board effects processor can be used with or in place of the on-board Digital Effects unit. The return level from an external processor into the ¼” effects return jack should be adjusted using the controls of the external processor. The on-board effects can be turned off by using the effects cancel jack, turning down the effects levels or using the program labeled “bypass”.
