ZAPCO ST-5X 5-CHANNEL CLASS A/B AMPLIFIER

The ST-5X is the All-In-One Studio amp.

Like the other ST-X amps the ST-5X is Class A/B even on the 5chnd, so you get tight solid bass.

The ST-5X has an input mode switch so you can use six channels of input, or only four, or even just two channels and get all 5 channels of output. So if you only have a stereo head unit you can still drive front and rear speakers plus a subwoofer.

Altogether, a lot of punch in not a lot of space.
