Description

The Isis M75P power amplifiers feature the same technology as in the M75D range, yet they offer a pure signal path from the inputs to the power stages for unaltered delivery of audio signals. They are the ideal choice for driving multi-way active speaker systems or multi-channel home cinema setups. When configured as a single channel mono amplifier, the Isis M75P will deliver up to 800W into a 4 ohm load. Stable into 2 ohms in stereo mode.

The Isis M75 range of amplifiers are state-of-the-art audio amplifiers feature our proprietary Excalibur output circuit, which couples extreme output capability with perfect control. The DX9 bias control method and managed power supply ensure outstanding performance with greatly improved thermal efficiency, thus maximizing component life.
The M75 range includes the M75D integrated amplifier and M75P power amplifier. Both models can be configured as stereo or as single channel amplifiers in bridged mode when higher power output is required. Stable into 2 ohms in stereo mode. Analog Domain M75 amplifiers are built to the highest standards and are backed by a 5-year manufacturer’s warranty.

Bridge mode

Bridge mode transforms the Isis M75P into a high power, balanced, single channel amplifier. The same signal drives both power stages, yet work in inverse phase relative to each other to provide more power and reduced distortion. Distortion reduction occurs through cancellation of the even-order harmonics due to the symmetry of the topology. You will need a second amplifier for a stereo setup.
