The new line of Gs Audio Compact Sound Quality series amplifiers are the evolution of the previous Sound Quality series.
These latest generation class D amplifiers, thanks to new integrated circuits, are able to offer excellent timbre and sound clarity, furthermore new IGBT power transistors with low thermal dissipation have allowed the chassis to be reduced in weight and size, offering dimensions similar to amplifiers "Brazilian" but superior control over the speaker.

Thanks precisely to the sound qualities, a size smaller than the previous GS Sound Quality series, we have called this series SQ Compact (Sound quality compact).

All 3 models currently available, the 4-channel model 190.4, the single-channel 550.1 and the two-channel model 280.2 have RCA and high level inputs which allow them to be perfectly adapted even to an audio system with a standard car radio.
The audio adjustments are arranged frontally rather than laterally for easier access in the case of installation in places with poor lighting and visibility.

As can be seen from the internal photos, these amplifiers have nothing to do with modern Brazilian digital ones, the round toroidals instead of square ones and large capacitors as well as vertically placed control boards help to reduce background noise and disturbances to a minimum, Input and output polyester capacitors filter any hum from the power supply and to complete the power supply terminal blocks are sized to accommodate a cable of up to 35mm2!
