GT Audio GT-500/x1D 1x500w Class D Monoblock 12v Power Amplifier

World RRP: £101.95


Product code: GT-500/x1D

GT Audio offers a very high level of performance with a relentless eye to offering the best possible value for money. These GT amplifiers are a modern Class D design that offers the absolute most performance possible to drive your subwoofer for the cost point. An adjustable low pass crossover is built in, alongside the essential subsonic filter to ensure optimal use of power. The GT Class D amplifiers are 1 Ohm capable and produce their maximum power into this load.

Version History

Since 7/8/23 the downloadable data sheet and online data matches the screen printing on the amplifier for LPF and subsonic filter. There are detail but not significant differences between the lab report (and hence the paper data sheet included with the amplifier in the box in relation to these 2 fields.)
