Not satisfy with Auto Calibration? Optimize Your Sony STR-DN1080 and other AV Receiver Sound Quality with These Steps

If you’ve been struggling with underwhelming sound quality from your Sony STR-DN1080, you’re not alone. Despite the promise of the "Full Flat" calibration mode, the results often feel lifeless and lack impact. After six years of experimenting, I’ve developed a method to significantly improve sound quality—not just for this model but potentially for other AV receivers as well.

Step 1: Positioning the Calibration Microphone

Start by placing the calibration microphone at the center of your room—not necessarily at your listening position. This placement helps avoid sound reflections from walls and floors that can distort the calibration process. For optimal results, position the microphone at least 1 meter away from both the floor and walls.

Step 2: Perform Auto Calibration

Next, activate the auto-calibration feature by pressing "Start." Allow the receiver to adjust itself based on the microphone’s input. Once the process is complete, save the auto-calibration settings.

Step 3: Fine-Tune with Manual Calibration

Auto calibration provides a solid foundation, but manual adjustments can take your sound to the next level. From your main viewing or listening position, fine-tune the following:

Speaker Distance

Volume Level

Speaker Size

Crossover Frequency

Adjusting Volume Levels

Use a sound level meter app (available on Google Play Store) to measure decibels (dB) and ensure uniform output across all speakers. All speaker has same dB except for height speakers (I use Onkyo Dolby Atmos-enabled speakers), increase the volume by an additional 3dB for better presence.

Optimizing Speaker Size and Crossover Frequency

Even if your center and surround speakers are identified as "large" during auto calibration, consider changing them to "small." This ensures that lower frequencies are routed to the main speakers or subwoofer for better performance.

For the crossover frequency, check your speakers’ specifications. Here are my adjustments:

Center and Surround: 80Hz

Height Speakers: Left at auto-calibration default (110Hz)

Step 4: Test Your Settings

Finally, test your calibration by playing your favorite movie. Pay attention to clarity, depth, and balance to confirm whether the adjustments have enhanced your audio experience.

Why I Developed This Method

My living room has poor acoustics, and the standard auto-calibration settings didn’t work for me. Through trial and error, I discovered that combining auto-calibration with manual adjustments dramatically improved the sound.
