Channel Capability and System Flexibility
9 amplified channels with 11.2-channel processing. 11.2 amplified channels. Both handle the same number of channels, so the decision rests on features, calibration and design rather than speaker count.
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
Both handle the same number of channels, so the decision rests on features, calibration and design rather than speaker count.
