The highly efficient technology of the EX Amplifier is always in a ready state for high performance operation. The EX Amplifier is designed to drive any loudspeaker with ultra low-noise, high power amplification. The internal gain switches allow you to further optimize the EX Amplifier to your system.

The high efficiency of Class D eliminates thermal modulation, making the EX amplifier resistant to output stage bias wander and sonic ghosting. The output power devices are operating as efficient switches, in that few output devices are needed to deliver considerable audio power. The EX Amplifier is designed with ultra-short signal paths and uses the absolute minimum number of output devices to deliver over 700 watts of audio power without loss of dynamics, remaining true to the audio source.
