    Light weight - Switch-mode PSU - Solidly built - Protection - Limiter 

    The G9 ASG series of professional power amplifiers are designed to give superb audio performance with all the features, control and sonic performance you might expect from G9. The ASG series amplifiers are all Class H topology and use Bi-polar devices on the output. The switch-mode PSU allows all versions to be 2U in height, while making sure they are both light-weight and capable of delivering stable power down to 2 Ohms.

    The ASG series amplifiers have been designed and built to exacting standards and are a good match for the G9 system products, including the superb “G” series professional plywood enclosures and the DSM 26 Digital Speaker Management system. The ASG professional power amplifier series adds to a high quality and compatible audio system package, a well priced series with no compromise from G9.
