Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer CHANNEL CALIBRATION Error Fix: Individual Channel Levels Imbalanced

Error code CHANNEL CALIBRATION on the Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer means: Individual Channel Levels Imbalanced. One or more of the 11.1.4 channels is too loud or too quiet relative to others. With 11 speakers across 3 wireless units, level matching is critical. Calibration: (1) use SmartThings app → Soundbar → Speaker Test — plays test tone from each speaker to verify all are operational, (2) adjust individual channel levels in SmartThings: Center, Surround, Height/Top channels can be individually boosted or reduced, (3) subwoofer level adjusted via Woofer +/- on remote, (4) run SpaceFit Sound calibration if available (see SPACEFIT FAIL), (5) manual adjustment: play multi-channel test content (Blu-ray speaker setup disc or Dolby/DTS demo clips) and adjust each channel by ear. Common issue: rear speakers too quiet from distance — increase surround level +3 to +6 dB.
