McIntosh is introducing the MI1250 12-Channel Power Amplifier for whole home audio applications, priced at $4,000, and available later this month or early November. The Class D-powered unit is capable of delivering 50 watts into 8 ohm or 90 watts into 4 ohm loads, care of closed loop digital switching amplifiers paired with “extremely robust” power supplies for “performance levels that are rarely achieved in distributed audio”.

The MI1250 is 2U rack mountable via included (but optional) mounting ears. Sporting efficient Class D amplification, both cooling fan noise and heat are mitigated. Multi-color LED lights on the front panel indicate channel status, while the rear panel provides unbalanced inputs and 2-pole Phoenix-style push-in speaker terminals. Also on the rear panel are volume controls for channel balancing, plus two digital coax or optical inputs along with channel summing circuits for mono distribution.

Other features include a signal overload protection technology for connected speakers, a ‘Sentry Monitor’ short-circuit protection against exceeding operating levels, BUS input and outputs for stereo signal distribution and 12-volt trigger capabilities for activating or turning off other McIntosh components. There is also a timed auto turn-off function if no input signal is detected.

McIntosh says the MI1250 includes characteristic company design cues, such as the black glass front panel housing an illuminated logo, along with a familiar form factor highlighted with silver trim. The MI1250 can be purchased/installed by McIntosh dealers and/or integrators.

Martin, this seems like an odd product. A high end, $4K, 50 WPC distribution amp. I can't believe there's much of a market for such a thing.
