Buying hardware
Choosing a new receiver?
Each guide lists current compatible models from entry level to flagship: Dirac Live, Audyssey, RoomPerfect, Anthem ARC, YPAO, Trueplay.
Denon and Marantz: Audyssey or Dirac?
Most current Denon and Marantz models ship with Audyssey and can be upgraded to Dirac Live by buying a licence. Dirac’s own site lists which models support which Dirac licences. You’ll need a separate USB mic for Dirac, because the Audyssey mic in the box doesn’t work with it. See Step 1: Choose and Buy Your Licence.
Still not sure?
- Look for a measurement mic in the box. Its brand or label usually names the system.
- Look in the receiver’s setup menu for an automatic speaker setup or calibration option.
- Check the model’s page on the manufacturer’s website for the room correction name.
Brand lists come from each manufacturer or Dirac’s compatibility pages, checked September 2026. Model support changes, so check your exact model.

Audyssey versions
Audyssey comes in three versions: MultEQ, MultEQ XT and MultEQ XT32. XT32 has much finer filters and adds separate EQ for two subwoofers. Denon and Marantz’s current ranges span all three.
YPAO versions
Every Yamaha receiver measures and equalises speakers. YPAO-R.S.C. adds reflection-aware EQ, and higher AVENTAGE models add multi-point measurement at up to 8 positions, angle and height measurement, and 64-bit EQ.
Other systems you might see
- Pioneer MCACC: measures up to 9 positions and sets levels, crossovers, distances and EQ.
- Onkyo AccuEQ: found on many Onkyo receivers. It sets levels, crossovers and distances and corrects the room’s effect on the sound.
- Sony D.C.A.C. IX: on Sony’s AV receivers, measures speaker height and position with a supplied mic.
- Samsung SpaceFit Sound and LG AI room calibration: automatic tuning on some soundbars and TVs, using built-in or remote-control mics.
LG’s AI Sound Pro isn’t room correction. It adjusts sound for the type of content you’re watching.
