Auto Set-Up/Room EQ Adjust

The Auto Set-Up/Room EQ Adjust feature eases setup hassles by confirming speaker phase, assessing the sizes of all of your speakers, measuring speaker-to-listener distances, and balancing speaker levels. With the Denon DMS-305 calibration-grade microphone (included with select Denon receivers) placed in your favorite listening seat, this feature uses a test tone generator  and proprietary programming to precisely balance speaker levels and fine-tune the delay and EQ settings for each speaker. The result is optimized system performance for your specific home theater room.

HDMI (High Definition Multimedia Interface)
This is a digital interface standard for next generation television developed based on the DVI (Digital Visual Interface) used for computer displays and optimized for use in non-professional equipment. With it, non-compressed digital video and multi-channel audio signals can be transferred with a single connector, eliminating the need to use separate cables for picture and sound and making it possible to make connectors smaller. HDMI is compatible with HDCP (High-bandwidth Digital Contents Protection), a technology for protecting copyrights that encrypts digital video signals.

DVD-Audio (DVD-A)
DVD-A is the audio version of a DVD. It uses an extended version of PCM technology and provides high frequency response to 96 kHz (slightly less than SACD) and a 144 dB dynamic range (greater than SACD). Conventional DVD players will not play the high definition data contained on a DVD-A disc.

Super Audio CD (SACD)
SACD is a next generation music format that provides more natural, ultra-high quality reproduction of both stereo and multi-channel music. SACD specifications allow a hybrid disc with high-density DSD information on one layer and CD-quality information on another layer, allowing you to play hybrid discs in both an SACD player and a conventional CD player. SACD format is based on DSD (Direct Stream Digital) technology which uses a 1-bit data stream with a sampling frequency 64 times higher than a CD. SACD offers high frequency response to 100 kHz and a dynamic range of 120 dB throughout the audible range. Conventional CDs are limited to a high frequency limit of 22.05 kHz (1/5 that of the SACD) with a maximum dynamic range of 96 dB.

Directional Correlation Deinterlacing (DCDi)
DCDi is a specialized video processing developed by Faroudja that involves advanced algorithms to remove the jagged edges that appear when standard interlaced video is viewed on progressive scan displays. DCDi converts standard interlaced signals into progressive scan signals in order to eliminate the stair casing effect that conventional upconverters can introduce to diagonal edges.
