INPUTS
 -The Shenandoah™ Stereo 60LT is equipped with two types of input jacks. The ¼” input is unbalanced and 
“line/instrument level” with a useable sensitivity from 50 mV to 1.6 volt. The input impedance is 220 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. If an instrument offers an unbalanced output it should be connected to the unbalanced input of 
the Shenandoah amp. Additionally, the precision input scaling preamp contains a 45 Hz, 12 dB/octave high pass filter 
(more effective and less intrusive than the more common 6 dB filters) and an “RFI” filter (radio frequency interference) 
to eliminate unwanted noise. The XLR input jack is balanced and “microphone level”, with a useable sensitivity from –
60 dBv to -30 dBv. It is not a line level input. 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 or other 
instruments), a balanced pad network will be necessary to use the balanced input. For instance, a Rapco “Pad Blox”,-
20 or -30 pad or similar product could be used. 
 
COMBINING XLR & ¼” INPUTS
 -A unique feature of the Shenandoah™ Stereo 60LT is the ability to mix the XLR 
balanced and ¼” unbalanced inputs on channel 1. In many situations, this effectively makes the amplifier function as a 
3 channel amplifier. The most effective way to use this feature is to set the volume on the channel using the XLR 
microphone input and then adjust the level control on the instrument itself (assuming that it has one) to blend levels 
between the 2 inputs.   
 
ON-BOARD STUDIO QUALITY STEREO DIGITAL EFFECTS
 -The Shenandoah™ Stereo 60LT contains a 24-bit, 
16 program stereo digital effects processor. We chose to use an industry leader in digital effects processing for 
realistic, high quality effects algorithms. Level differences are normal when switching between different effects; just 
adjust the channel send and master level controls accordingly. The effects level control on each channel adjusts the 
send level to the digital effects processor. The digital effects level in the master section controls the effects return level 
from the processor. Turning up the channel effects send will yield lusher effects response. Running the channel effects 
send lower and the master level higher will yield softer effects response.
