DTS-ES Discrete 6.1 and Dolby Digital EX with Power Amps for 6 Channels DENON's Basic Design for High-Quality Sound Reproduction• Power Transformer for High Power DrivenThe chassis that supports the large transformer has beendesigned to absorb vibration, and the transformer is housedinside a highly rigid frame to secure it more solidly to the chassis.In addition, a cushioning material has been placed around thecore of the transformer to minimize interference on the signaland enable more faithful reproduction of the original sound.DENON's higher-end models incorporate these low-noise designs,such as the use of short rings.• Twin Drive RectifierDENON's Twin Drive Rectifier design uses two rectifying diodes in parallel to bring out themaximum potential of the large transformer. Since the rectifiers power the large blockcapacitors at low impedance, they are able to supply ample current to reproduce deepbasses as well as sudden bursts of sound from percussion or other musical instruments.• Large Aluminum Extruded HeatsinkDENON uses large heatsink made of extruded aluminum. Theyhave been placed in a design that ensures mostly uniformtemperatures throughout the heatsink so that the outputtransistors for all channels can be driven under uniformconditions. This in turn ensures that all channels respond withequal performance to the demands of the audio signals. Fully Discrete, Equal Power Six Amplifier Channels, 90 Watts EachFront 90 W + 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Center 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Surround 90 W + 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Surround Back 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)For 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 mainchannels. A large capacity power supply includes a high current power transformeralong with discrete power output devices on all six amplifier channels for highest dynamicrange and superb reproduction clarity. Single-Channel Surround Back Power Amp for 6.1 Surround and2 Speaker Terminals for 7.1 SurroundThe AVR-1804 is equipped with a total of 6 power amps including one for the SurroundBack speaker to give you more clearly defined sound localization at the rear for 6.1-chan-nel surround sources such as DTS-ES Discrete 6.1, DTS-ES Matrix6.1, Dolby Digital EX,and DTS-ES NEO:6. The AVR-1804 also provides you with 2 speaker terminals for theSurround Back channels, allowing for the ultimate home theater experience in amazing7.1-channel Surround. 32 bit High Quality DSPA-high -quality 32-bit DSP “MELODY 32” from Analog Devices has been used in the DSPprocessor, placing the AVR-1804 at a higher rank than other models of this class in its abilityto accurately decode and reproduce the superior quality of surround sources. 24 bit, 96 kHz High Resolution D/A Conversion Wide-Range Play Capability for DVD-Audio and SACDThe power amp circuits of the AVR-1804 have been meticulously designed to reproducethe exceptionally high sound quality with wide frequency response from 10 Hz to 100 kHz. Cinema EqualizerThe sound from movie sources recorded in Dolby Digital, DTS or otherformats emphasizes high-frequency range due to a theater’s front speakers beingplaced behind the movie screen. If this sound is reproduced in the home theaterwithout correction, the high-frequency range is too strong. The AVR-1804 features aCinema Equalizer to correct these high-frequency components so that the sound isclearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II,Dolby Digital EX and DTS surround modes) Personal Memory Plus, for Easy OperationThe AVR-1804 includes the Personal Memory Plus function that automaticallyremembers the surround mode you last used for each program source, so that you do notneed to select the mode again for that program. On Screen DisplayThe AVR-1804 lets you make system settings via diaplays on your TV scren from thecomfort of your chair. Acclaimed Customization FeatureAs with all of DENON’s high-grade A/V receiver, the AVR-1804 lets you adjust delaytimes and other parameters so that you can customize the performance of the AVR-1804to suit your own home theater and enhance operating ease. The adjustments are easyto make via a dialog format on the fluorescent display on the front panel. Thesecustomized features are then stored, for each source input and surround mode, inPersonal Memory Plus so constant readjustments are not required. Multi-Function Preset Memory Remote Controller with Glow-keysThe supplied system remote controller features a large selection of remote controlcodes to operate other components in your home theater system, including codes forselected DENON models, along with remote control codes from other manufacturers.The most frequently used buttons are laid out separately for TV, VCR and DVD, formaximum ease-of-use.* Remote control codes cannot be used with the products of othermanufacturers and some DENON products.AVR-1804DTS-ES and Dolby Digital EX A/V ReceiverN E W M O D E L I N F O R M A T I O N
