The Isis

The Isis range of dual channel amplifiers from Analog domain represents the current state of the art in linear amplification technology. It is the result of 15+ years experience in high-performance amplifier circuit design, created to deliver exceptional performance at an attractive price point.

The Isis features our recently disclosed proprietary Excalibur circuit. Near-zero distortion, a noise floor well below the human perceptual threshold and the generous power output capability of the Excalibur give the Isis its ability to amplify signals with extreme resolution and control, raising the enjoyment of music to an unprecedented level.

The Isis is available in three configurations: two integrated amplifiers and a matching 2-channel power amplifier, for installations requiring more power in stereo, or for building multi-way systems with frequency splitting, or multi-channel systems:

Isis M75D
– Stereo integrated amplifier, stepped analogue volume attenuator, remote control

Isis M75A – Stereo integrated amplifier, linear analogue volume attenuator, manual control

Isis M75P – Stereo power amplifier
