M•800 SPECIFICATIONS

Maximum Power:

175 watts per channel into 8 ohms

275 watts per channel into 4 ohms

400 watts per channel into 2 ohms

550 watts into 8 ohms bridged

800 watts into 4 ohms bridged

Note: Power ratings are specified at 120VAC line voltages.

The M•800 power amplifier draws large amounts of cur-

rent from the AC line with continuous sine wave testing.

Accurate measurement of power requires a steady and

stable AC supply. This means the line impedance must

be very low to insure that the peak AC line voltage does

not sag to less than 97% of its value.

If driving highly reactive loads, we recommend that the

limiter circuit be engaged.
