Perfect Positioning Without the Effort

AccuEQ Room Calibration streamlines the initial setup of your home theater by ensuring your receiver and speakers are properly calibrated to the room they’re in. This technology compensates for differences in speaker size and distance to equalize response so you get exceptional audio playback no matter the space you’re in.

Hear Every Whisper

Emphasize dialogue and vocals with the TX-SR3100’s Vocal Enhancer technology. By adding the Center element to your Front Left and Front Right speakers, it allows you to more clearly pick up on conversations during action scenes with loud explosions or quiet moments in heady dramas—no matter what where the volume is set.

Hear the Musical Nuance

Our Music Optimizer DSP listening mode reconstructs data that can be lost when audio files are compressed (which can happen with WMA, AAC and MP3 formats). This technology brings audio files back to their original lossless quality by creating new signals to restore minor details left out during the compression process.

Virtually Immersive

When playing any Dolby format, engaging Dolby Atmos Height Virtualizer enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers. Sounds that should be coming from up high and far off will sound like they really are.

With Klipsch Optimize Mode, integrate Klipsch Reference and Reference Premiere speakers seamlessly with your Onkyo AV receiver. Simply select the model speakers you’ll be using for each individual channel, and the optimized crossover setting will be automatically applied.
