PRODUCT DESCRIPTION � The Shenandoah� Stereo 60
input and channel 1 is also equipped with an XLR balanced microphone input (with phantom power). The 2 inputs on channel 1 are summed (mixed) together at a 1:1 ratio. Each channel offers a 3 band equalizer with a sweepable midrange frequency control. Equalization centers were carefully selected for use with acoustic instruments. Each channel also contains individual send controls to the on-board Alesis® 15 program STEREO digital effects circuit. The channel signals are then summed together, mixed with the digital effects return and passed on to the internal dual 30 unbalanced line output, and two 1/4� speaker jacks.
INPUTS � The Shenandoah� Stereo 60 is equipped with 2 types of input jacks. The ¼� input is unbalanced and
accepts instrument level to line level with a useable sensitivity from 100 mV to 1 volt. The input impedance is 300 k ohms. The ¼� input will also accept most active balanced line sources, automatically unbalancing them by recognizing the tip portion of the balanced signal. Additionally, the precision input scaling preamp contains a 50 Hz, 12 dB/octave interference) to eliminate unwanted noise. The XLR input jack is balanced and �microphone level�, with a useable sensitivity from �60dBv to �30 dBv. It contains a precision full range differential microphone preamp with phantom power. For use with higher level sources (such as the balanced line level output from a keyboard), a balanced pad network will be necessary to use the balanced input. Phantom power is 13.6 volts, compatible with virtually all commonly used live sound condenser microphones. Dynamic microphones can be used with no ill effect.
