7-Channel Equal Power
7-Channel Equal Power is a feature used in various Denon amplifiers to connect 7 speakers independently so that separate power amps connected via pre-outs are not required. It allows you to connect the second 'surround back' speaker to complement the surround back speaker for 6.1, straight off the main amplifier without adding a power amplifier to support 7.1 surround formats. Amplifiers with 7-Channel Equal Power have built-in separate internal amplifiers to power each channel independently, thus allowing you to enjoy the same high power output capability per channel, giving a balanced and truly high-impact surround-sound environment.

7-Channel Stereo
Denon's 7-Channel Stereo mode enables top quality normal two channel stereo output from the surround speakers to provide a unique 7 channel stereo option. This mode can be fully utilized from any high quality stereo source via CD, tape, FM-radio or video recorder for dynamic 7-channel output. The 7-channel stereo is available if you have a surround back right speaker connected as well as the surround back left speaker used in 6.1, otherwise you can still experience multi-channel stereo output using a 5-channel-stereo or 6-channel-stereo configuration.

8-Channel Input
These input jacks are for inputting multi-channel audio signals in high definition MUSE 3-1 format, multi-channel audio signals from an MPEG multi-channel decoder, SACD and DVD-Audio. The 8 channels are the Front left, Front right, Center, Surround left, Surround right, Surround Back Left, Surround Back Right and the Subwoofer. These connections are made by using 8 standard phono (RCA's) cables. The inputs are on the amplifier and by selecting 'Ext in' you can receive analog audio signals via a source such as a DVD player. Denon DVD players can be connected via the 6 phono cables to a Denon amplifier's 6-CH or 8-CH EXT inputs to allow for SACD or DVD-Audio transfer. This can also be used as an alternative to IEEE1394-output (Digital Audio) FireWire connection or the DENON LINK connection.

Advanced AL24 Processing
The acclaimed Advanced AL24 DSP processing improves the fidelity of high resolution stereo PCM sources such as CD and DVD (up to 192kHz sampling frequencies). Through sophisticated DSP processing algorithms, it improves low level detail and enhances fidelity by up-sampling and adaptive filtering techniques. Advanced AL24 also provides increased dynamic range and spatial information, bringing out all the nuances with optimum clarity and natural fidelity.

Audyssey MultEQ XT
The Audyssey MultEQ XT provides advanced room correction and calibration technology. During the Auto Set-Up mode, MultEQ XT automatically determines how many loudspeakers are connected, whether they are connected in phase and whether they are satellites or subwoofers. After processing, it then analyzes and calibrates speaker level, size, and distance. MultEQ XT detects the proper crossover point and determines correct frequency response for up to eight listener positions simultaneously. Denon's implementation of MultEQ XT uses multiple Texas Instruments' Aureus DSP processors with high-end digital-to-analog converters. Both the Room EQ and Auto Set-Up features can be disabled if required. For additional information, visit the Denon Tech Showcase.

Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, dts, or other formats emphasizes high-frequency range due to a theater`s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range can be too strong. Denon amplifiers feature a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to.

Directional Correlation De-interlacing (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 up-converters can introduce to diagonal edges.
