GT Audio GT-80/x4AB 4x80w Class AB 12v 4/3/2 Channel Bridgeable Stereo 12v Power Amplifier

World RRP: £101.95


Product code: GT-80/x4AB

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 traditional Class AB product, offering outstanding sound quality in return for conventional form factor. Features of note are a very useful crossover section that has the ability to cross over the HPF all the way up to 3k which is very helpful for running 3 way style speaker kits, and an input section happy to deal with a 6.5V line input. The amplifier is happy to operate in bridged configuration as either a 2 channel or tri-mode setup but, as ever, care must always be taken to observe minimum impedance requirements in system design for reliable and high performance.
