Sound fields, effects, and speakers

Couch Amp sound page with sound fields, effects, and speaker trims

The sound page covers the receiver’s audio processing end to end:

Sound field

All eight sound fields as one-tap chips — 2ch Stereo, Direct, A.F.D., Multi Stereo, A.F.D. Movie, Dolby, DTS:X, and Audio Enhancer. When Pure Direct is on, the grid dims and shows BYPASSED, just like the signal path.

Effects

Pure Direct — bypasses processing entirely
DSD Native — native DSD passthrough
360 Spatial Sound Mapping — when your speaker layout supports it

Speakers

Calibration — switch the DCAC correction type: Full Flat, Engineer, Front Reference, or Off
Front Speakers — the amp-level speaker output selector (Speaker A / Off; A/B models show all their options)
Level trims — every configured speaker, ±10 dB in half-dB steps, with live preview while you drag

The EQ tab adds bass and treble shelves per speaker group with the same slider style.
