Product InformationFor optimum Dolby Digital and DTS reproduction, the AVR-1804 features high quality, wideband audio amplification, providing 90 watts power output for each of the six main channels. A large capacity power supply includes a high current power transformer along with discrete power output devices on all six amplifier channels for highest dynamic range and superb reproduction clarity.The AVR-1804 is equipped with a total of 6 power amps including one for the Surround Back speaker to give you more clearly defined sound localization at the rear for 6.1-channel surround sources such as DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, Dolby Digital EX, and DTS-ES NEO: 6. The AVR-1804 also provides you with 2 speaker terminals for the Surround Back channels, allowing for the ultimate home theater experience in amazing 7.1-channel Surround.The AVR-1804 includes the Personal Memory Plus function that automatically remembers the surround mode you last used for each program source, so that you do not need to select the mode again for that program. The AVR-1804 lets you make system settings via displays on your TV screen from the comfort of your chair. As with all of DENON's high-grade A/V receiver, the AVR-1804 lets you adjust delay times and other parameters so that you can customize the performance of the AVR-1804 to suit your own home theater and enhance operating ease. The adjustments are easy to make via a dialog format on the fluorescent display on the front panel. These customized features are then stored, for each source input and surround mode, in Personal Memory Plus so constant readjustments are not required.
