■Dolby Digital, Dolby Pro Logic II and Dolby Digital EX Decoder
■6 Channel Stereo Mode
DENON's popular 6 Channel Stereo mode transforms your favorite 2-channel
sources such as CD, tape, stereo radio and stereo video sources into exciting surround
sound, free of delay effects and unnatural artifacts, from all six speakers. This 6
Channel Stereo mode was originally developed by DENON to enhance music lovers'
enjoyment of home theater ambience.
■Virtual Surround Mode
Surround yourself with sensational 3D soundfield envelopment using just one pair of
speakers. The AVR-1804's Virtual Surround mode provides a dramatic psychoacoustic
surround sound effect, using two speakers with all sources.
■DENON DSP Surround Modes Add Listening Excitement
Put yourself in the middle of your favorite concert hall and music environments with
DENON's DSP acoustic environment simulation modes. These DSP modes add
spacious surround sound enhancements to your favorite music and video sources.
■Adjustable Cross-Over Switching
The AVR-1804 supports subwoofer cross-over switching with a choice of 4 cross-over
frequencies: 80, 100, 120 and 150. This lets you more accurately match the
performance characteristics of the subwoofer to the main speaker system.
■Support for Multi-Zone Configurations
The AVR-1804 provides a Multi Zone Output function and a Select function that let
you output different surces to multiple zones. Sources can be selected for output to
an additional zone, in addition to the main room.
■Multi Zone Power Amplifier Assign
The AVR-1804’s Power Amplifier Assign function lets you assign the Surround Back
(SB) amplifier channel when the system is not configured for 6.1 to instead drive the
Multi-room Zone 2 speaker (mono), with 90 Watts per channel output power, while
still providing 5 discrete amplifier channels to drive all speakers in a 5.1 configured
home theater room.
