Precision Audio Products microphone preamplifier is a small unit, measuring about 41 2 by 51 2 by 2 . Facing the operator are two potentiometer knobs, controlling volume for channels one and two, a gain switch (low, mid and high), a bass cut switch (flat and roll off), and a power switch, which has a provision for 48v phantom power (very convenient). Each pot is large (green for channel 1; red for channel 2) and easy to turn; each channel has an LED that flashes red when the pot needs to be turned down. There is a low battery warning light, which comes on when the batteries reach 6.5v On the left side of the unit are two XLR balanced microphone inputs; on the right side, there are two XLR line outputs. The unit is powered by two 9v batteries, housed in a compartment on the bottom.
