The Isis M75P is a precision, solid state linear amplifier, intended for amplifying audio frequency signals. It is the product of over 15 years of circuit refinement, aiming to escalate the quality of audio reproduction to the highest level of fidelity. The proprietary circuit technology combines high performance with high efficiency and high reliability.
The operating mode of the Isis M75P is Class AB+G. Efficiency is greatly enhanced by employing a tiered power supply with proprietary voltage management in the power stages, thus providing high output power while minimizing power waste and consequent heat. Build quality is to the highest standards, ensuring many years of reliable operation.

Product Information:

Stereo mode

To use the Isis M75P in Stereo mode, set the MODE switch to “STEREO”. Connect loudspeakers to the respective binding posts. The positive line of the speaker cable should be connected to the RED binding post of each output. The minimum rated load is 4 ohms. If a lower impedance load is connected, it may trigger the short-circuit protection or cause overheating, resulting in intermittent output or no sound at the output. The red LED above the corresponding output will glow in case of a short circuit or low impedance current limiting, indicating that the respective channel is disabled.

Bridge mode

Bridge mode transforms the Isis M75P into a high power, balanced, single channel amplifier. Both power stages are driven by the same signal, 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.
