| Features And Benefits: |
 | 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. |
