    Channel Capability and System Flexibility

    MM-7055: 5 amplified channels. MM-8077: 7 amplified channels. The MM-8077 handles more channels. If you might add height or wide speakers later, plan pre-wiring for the larger layout now — false-ceiling work is the expensive part to redo.

    Installation Considerations

    What changes on site between the two.

    • Rack depth and ventilation — larger chassis and power amplifiers need more airflow, especially in summer.
    • Speaker pre-wiring for the largest layout either model might run, before false-ceiling finishes.
    • Subwoofer count and positions, measured at every seat.
    • Calibration is done for every installation; the room correction system differs, the process does not.

    Upgrade Considerations

    The MM-8077 handles more channels. If you might add height or wide speakers later, plan pre-wiring for the larger layout now — false-ceiling work is the expensive part to redo.
