Marantz MM7055 - 5-Channel Power Amplifier

The Marantz MM7055 is a five-channel discrete power amplifier built for home theater systems where a separate, high-output amplification stage is preferred over the internal amplifiers of an AV receiver. Delivering 140 watts per channel into 8 ohms across all five channels simultaneously, it is appropriate for demanding speaker loads in mid-to-large screening rooms.

Both balanced and unbalanced inputs are provided for all five channels, selectable via a front-panel switch. Signal-to-noise ratio is rated at 105 dB, and total power consumption is 660 watts. The 5U chassis measures 17-3/8 x 7-3/16 x 15-1/8 inches and weighs 34.6 lb, reflecting the build quality and transformer capacity required for sustained multi-channel output.
