2. Verify Results: Check that the receiver has correctly identified speaker sizes and distances.
3. Manual Fine-Tuning: After auto-setup, you may manually adjust channel levels and the subwoofer level to personal preference.
4. Bass Module Placement: If bass sounds uneven, try moving the bass module to a different corner or along a different wall.

WARNING! During calibration, ensure the room is as quiet as possible. Do not touch the microphone during the process.
