According to the AVR 51 documentation, proper configuration is key to achieving a "better" audio experience.

Ventilation is Critical: Place the unit on a firm, level surface with ample space above and below. The manual warns against placing it on carpets or in enclosed cabinets without airflow, as high-current amplifiers generate significant heat.

Speaker Calibration: Use the Test Tone button on the remote or front panel to balance output levels. Ensuring all five channels reach your listening position at the same volume is the fastest way to improve surround-sound immersion. Troubleshooting and Maintenance

If you encounter issues like the unit not powering on or sound distortion, the AVR 51 Service Manual offers deeper diagnostic paths.

Resetting the Unit: If the digital processor (DSP) glitches, a common fix for Harman Kardon receivers involves a factory reset, typically performed by holding specific front-panel buttons (like "Surround Mode" and "Tuning") while powering on.

Digital Input Selection: Ensure the correct digital input (Optical or Coaxial) is assigned to your source. If the channel indicators on the display flash, it means the digital signal has been interrupted. Harman/Kardon AVR-51 - Classic Audio
