Equipped With The Latest Surround Sound Decoders
The AVR-2311CI features high resolution audio decoders, including Dolby TrueHD and DTS-HD Master Audio. It also comes equipped with Dolby’s Pro Logic IIz decoder, which provides superb surround sound from conventional stereo audio sources such as CD. The Pro Logic IIz decoder also features the ability to produce two additional front height effect channels, which provides a dramatically expanded front soundstage.

HD Radio
In addition to conventional AM and FM tuning, the AVR-2311CI also features HD Radio. With HD Radio AM sounds like FM, and FM HD radio sounds like CD.

HDMI 1.4a Includes 3D Blu-ray Compatibility
Featuring 6 HDMI inputs, the AVR-2311CI is also equipped with Denon’s high resolution video processor, which accepts standard definition video sources and upconverts them to HDMI. The latest HDMI 1.4a standard is supported, which provides 3D pass-through (Broadcast and Blu-ray), and also supports Audio Return Channel. The HDMI upconversion allows for a single HDMI cable run to the TV, avoiding the expense and hassle of multiple cable runs.

Easy Setup With Automatic Room Acoustic Correction
Audyssey MultEQ dynamic room acoustic correction system features a microphone (included) to automatically measure the speaker configuration and provide acoustic tailoring for the best surround sound experience, and provides quick and easy setup. Dynamic Volume minimizes jarring volume jumps during commercial breaks, and Dynamic EQ provides a natural tonal balance even at very low volume levels.

Quality Discrete Power Amplifier Section
The equal power amp design features 7 discrete power amp circuits, and each channel is rated at 105 watts (8 ohms, 20 Hz to 20 kHz, .08% THD). For configuration flexibility, Denon’s Power Amp Assign function lets you use 2 of the amp channels for surround back speakers, or front height effects speakers, or they can be assigned for stereo second zone multi-room use.
