The new analog six-channel poweramplifier for sound gourmets
The wonderfully analog, beautifully large amplifi ers still exist, where sound is everything, and compactness and effi ciency are relegated to the bottom of the list. There is a wide choice of four-channel and two-channel amplifi ers on the market. With its six channels, the GZUA is not unique but quite alone with its high-end ambitions. Yet the concept makes perfect sense. The GZUA has four smaller channels and two particularly powerful ones – ideal for a large, sophisticated threeway system.
The GZUA 6SQ is visually indistinguishable from its predecessor, the GZUA 6.200SQ-Plus. An elongated, titanium-colored strand cast housing with a height of only 48 millimeters, the cooling fi ns at the back and the connectors and potentiometers lined up next to each other at the front. On the far right are the solid power connections, then you‘ll find the four-pack of 30-amp fuses. After that, there are speaker connections, controls, and RCA input jacks for the three-channel pairs. Everything is solidly made with excellent, smooth-running controls and sturdy jacks fastened with nuts. There are only high and low pass fi lters to operate. One looks for frills in vain; instead, the crossovers are designed to perfection. That means you can switch them off so that the signal does not have to go through the potentiometer when the fi lters are not needed. The 10x multiplier switches are also helpful, as the frequencies can be adjusted over a wide range without using bad potentiometers with too broad a resistance range.
