How to Run AccuEQ Room Calibration on the Onkyo TX-NR6100

To run AccuEQ Room Calibration on the Onkyo TX-NR6100, plug the supplied setup microphone into the SETUP MIC jack on the front panel and set it at your main listening seat. Then start the Initial Setup wizard and follow the prompts until the test tones finish. Select “Save” at the end.

On a new receiver, AccuEQ is part of the wizard that runs the first time you turn it on. To run it again later, open the Setup menu and go to 7. Miscellaneous > Initial Setup. AccuEQ doesn’t have its own item in the Setup menu. The measurement takes 3 to 12 minutes, and the test tones are loud. Make sure the room is quiet and your subwoofer is switched on first.

What AccuEQ actually does

AccuEQ plays test tones through each speaker and listens with the microphone. From those measurements, the receiver sets:

• Level: how loud each speaker plays, so no single speaker overpowers the others.
• Distance: how far each speaker is from your seat, so sound from every speaker reaches you at the same time.
• Crossover: which bass frequencies go to the subwoofer instead of smaller speakers.
• Equalizer: tone adjustments that correct for the way your room colors the sound.

It only measures the speakers the receiver has been told about. So the speaker setup has to be right before you calibrate.

Get ready (5 minutes)

1. Check your speaker wires. Twist each wire end tightly so no loose strands stick out of the terminals. Onkyo says that if the receiver suddenly shuts off during calibration, stray strands touching the rear panel or each other are the likely cause.
2. Turn on the subwoofer. Set its volume knob to a little more than halfway, as Onkyo recommends.
3. Quiet the room. Turn off fans, air conditioning, and dishwashers if you can. Close windows facing a busy street.
4. Warn the household. Each speaker plays its tone at high volume. Keep pets and sleeping kids in mind.
5. Find the microphone. It’s the speaker setup mic that came in the box. It plugs into the SETUP MIC jack on the front panel.

Where to put the microphone

Put the mic where your head usually is, at your main seat. That’s the spot AccuEQ tunes the system for.

• A small camera tripod works well. Onkyo’s manual includes an illustration for mounting the mic on one.
• Our tips: set it at about the height of your ears when you’re sitting down, and don’t hold it in your hand or bury it in a soft cushion.
• Stay out of the straight line between the mic and the speakers while it measures.

How to run AccuEQ Room Calibration

Step 1: Get to the AccuEQ screen

1. Turn on the TV and switch it to the receiver’s input.
2. If this is a brand-new or freshly reset receiver, the Initial Setup wizard appears by itself. Otherwise, press the Setup button on the remote (or SETUP on the front panel), select 7. Miscellaneous > Initial Setup, and press ENTER.
3. Work through the wizard’s earlier steps. In Speaker Setup, check that Speaker Channels, subwoofer, height speaker type, and Speaker Impedance match what’s actually connected, then press ENTER.
4. Listen as a test tone plays from each speaker. If every speaker sounds, select Next and press ENTER. If one is silent or in the wrong place, choose Back to Speaker Setup and fix the setting or the wiring.
5. Continue past the Multi Zone Sound Check and ARC Setup steps. The next step is AccuEQ Room Calibration.

Step 2: Measure

1. Place the microphone at your listening position and plug it into the SETUP MIC jack on the receiver.
2. The subwoofer plays a test tone. Once you hear it, press ENTER.
3. Press ENTER to start. Each speaker plays test tones, and the receiver detects which speakers are connected and measures the background noise in the room. Stay quiet.
4. The receiver shows which speakers it found. If the list is correct, select Next and press ENTER. The tones play again, and this time the receiver works out the best levels, crossover points, and other settings. If you don’t press anything for 10 seconds, the second round starts on its own.
5. When the measurement finishes, the results appear on screen. Use the cursor buttons to look through them.
6. Select Save and press ENTER. Your calibration is now stored.
7. Unplug the microphone from the SETUP MIC jack.

If the detection screen lists a speaker you don’t have, or leaves one out, don’t select Next. Check that speaker’s wires and your Speaker Channels setting, then run the calibration again.

After calibration: check and fine-tune

Look over the results

Open the Setup menu and go to 2. Speaker. Crossover, Distance, and Level Calibration now hold AccuEQ’s numbers. A quick check with a tape measure can catch mistakes. Onkyo notes that some speakers can cause small errors in the measured distances. If a distance is clearly wrong, correct it by hand under 2. Speaker > Distance.

Choose how the room EQ is applied

During playback, press Q on the remote to open the Quick Menu. Select Room EQ, then AccuEQ. You’ll see two choices:

Setting	What it does	Try it when
On (All Ch)	Applies AccuEQ’s room correction to every speaker.	You want the full correction. This is where most people start.
On (ex. L/R)	Applies the correction to every speaker except the front left and right.	You like how your front speakers sound on their own, especially for music.

This setting is saved separately for each input. You could use full correction for movies on your Blu-ray player and leave the fronts uncorrected for a turntable, for example.

The Room EQ section also has Manual Equalizer. It lets you pick Preset 1 to Preset 3, which you build yourself under 2. Speaker > Equalizer Settings. Leave it off unless you have a specific tone change in mind.

If you own THX-certified speakers

THX recommends setting the crossover to 80Hz(THX) for THX-certified speakers. It also suggests adjusting each speaker by hand for your room, rather than relying only on automatic calibration.

Upward-firing (Dolby Enabled) speakers

If your height channels are Dolby Enabled speakers sitting on top of your front or surround speakers, look at 2. Speaker > Dolby Enabled Speaker. There you can enter the distance to the ceiling and turn AccuReflex on or off. Onkyo’s spec sheet describes AccuEQ as working together with AccuReflex.

When to run AccuEQ again

• You moved a speaker, your seat, or large furniture.
• You added or removed speakers, or changed the Speaker Channels setting.
• You replaced the subwoofer or changed its volume knob.
• You did a factory reset. A TX-NR6100 factory reset erases your calibration along with every other setting.

Fixing AccuEQ problems

“Noise Error” appears

Onkyo says this can come from a problem with one of your speakers. Check that each speaker plays normally and its wires are secure. Also make the room as quiet as you can, since the receiver measures background noise too. Then run the calibration again.

The subwoofer level ends up at the lowest setting

If the results show the subwoofer level corrected all the way to its lower limit, the receiver couldn’t finish adjusting it. Onkyo’s fix is to turn down the volume knob on the subwoofer itself before you measure. Start a little above halfway, as recommended. If it hits the lower limit anyway, turn the knob down a bit and run AccuEQ again.

The distances don’t match your tape measure

Some speakers can throw off the distance measurement slightly. Enter the correct distances under 2. Speaker > Distance. You don’t need to rerun the whole calibration.

The receiver turns off in the middle of calibration

That’s the protection circuit reacting to speaker wires touching the rear panel or each other. Put the receiver in standby, re-twist and reconnect the wires so nothing sticks out, and start again.

A speaker isn’t detected

Go back to Speaker Setup and confirm the speaker is included in your Speaker Channels choice. If you use Zone 2 speakers, see our TX-NR6100 Zone 2 setup guide. Some main-room speakers can’t play while Zone 2 is on, so turn Zone 2 off before you calibrate.

Does the TX-NR6100 have Dirac Live?

No, not according to Onkyo’s official information as of September 2026. Onkyo’s Dirac Live page lists TX-RZ models, and Dirac’s own list of Onkyo products adds the TX-NR7100. Neither includes the TX-NR6100. The TX-NR6100 firmware notes don’t mention Dirac either. AccuEQ is this receiver’s built-in room correction, so it’s worth getting it right.

Onkyo’s full wizard steps are in the TX-NR6100 Initial Setup support article. The Quick Menu and troubleshooting details are in the TX-NR6100 instruction manual (PDF).
