The D3220 dual-channel preamplifier circuit is a dual preamplifier consisting of two amplifiers and two ALC transistors (can be used as a variable monitor). The internal single-ended push-pull output stage can directly drive the meter and ALC circuit. The ALC between the channels is better balanced.
