A new preset Audyssey memory mode allows owners to store two Audyssey configurations and switch between them on the fly, too.
Last but not least, Denon has trickled down its ‘Pre-Amplifier’ mode from its 2019 flagship
AVC-X8500H to the new AVC-X3700H, AVC-X4700H and AVC-X6700H. Pre-Amplifier mode provides more tolerance in clipping levels by disconnecting internal amplifiers when the receiver is used as an AV processor and all speakers are powered by external amplifiers.
