Questions and answers
Error ack no sound
The error acknowledgment for no sound on the Marantz SR7000 involves checking several components depending on the input mode:
1. Analog Stereo Mode:
- If the test tone is OK but no sound, check if Analog S-Direct is active.
- If Pre output is not OK, check volume control, power amp, HDAM, QC04, speaker relay, or pre-out relay.
- If test tone is not OK, check audio input (PS04, PS54), P604 circuit, or QK04 (ADC).
2. PCM Stereo (Digital In):
- Check DIR (QR01) and LED status.
- If 96k PCM is not OK, check DAC circuit (P604).
- If test tone is not OK, check DSP (Q601) and its input stage (QR06).
3. AC-3/DTS Decode:
- Check volume control, HDAM, and QC04.
The error indicates a fault in one of these paths and helps isolate the faulty component.
