Description
The Black EX Dual Mono Amplifier is designed in a custom plated high-grade aluminium chassis that contains independent power supplies and amplifiers unique to Black EX for true dual mono performance. The EX Amplifier is rated at 350W/700W per channel producing incredible high-power accuracy and musicality to your loudspeaker.
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 optimise 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.
High Dynamic Range – Low Noise and Distortion: The single stage architecture of our linear switching power stage has remarkable audio band noise characteristics. With over 130dB dynamic range potential and vanishingly low IMD and THD distortion is completely transparent, hear-through performance is delivered.
