Our take on the Denon AVR-1804by Crutchfield's Barry Montgomery
When it comes to incredible home theater realism, Denon's AVR-1804 really delivers! 90 high-current watts x 6 channels of ultra-clean power envelops you in an engrossing, 360º soundfield. Built-in 32-bit decoding for Dolby® Digital EX and DTS-ES® let you enjoy precise 6.1-channel sound from any Dolby Digital or DTS soundtrack. You can also transform any stereo or Dolby Surround source into convincing 6.1 audio using DTS Neo:6 modes. Cinema EQ optimizes movie soundtracks for home theater-sized rooms.
Thanks to dual-room/dual-source output, you can enjoy 6.1-channel sound in your main listening room while a housemate listens to a different audio source in another. You can use the preamp-level second-room outputs along with a receiver, amplifier, or shelf system for stereo sound in your second room. Or you can assign the receiver's "surround back" channel to power your second-room speakers in mono, and still enjoy 5.1-channel surround sound in your main listening room.
The handy remote not only controls this receiver, but also TVs, DVD players, and VCRs from almost any manufacturer. An on-screen display puts the receiver's control menus on your TV screen for easy navigation. You get plenty of ins and outs for building a great system, too, including HDTV-compatible component video switching for 2 sources, 5 digital audio inputs, and 5 S-video inputs. Composite-to-S-video conversion simplifies hookup to your TV. And the front panel sports S-video and optical digital inputs for easy hookup of camcorders, game systems, and other portable devices.Details:

Features and Specs
Digital Signal Processor: The AVR-1804 features a 32-bit "Melody 32" DSP processor from Analog Devices. This high-quality DSP chip gives the receiver the ability to accurately decode and reproduce the superior quality of DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS Neo:6, Dolby Digital EX and Dolby Pro Logic II.
24-bit, 96kHz D/A Converters: The AVR-1804 uses highly accurate 24-bit, 96kHz D/A converters on all six channels to handle digital to analog conversion, giving you superior sound quality.
Surround Modes: This receiver incorporates a wide variety of surround modes to bring you maximum enjoyment from your audio and video software. The surround modes include:
- Dolby Digital
- Dolby Digital EX
- Dolby Pro Logic II (Movie and Music)
- DTS-ES Discrete 6.1
- DTS-ES Matrix 6.1
- DTS Neo:6 (Cinema and Music)
- Rock Arena
- Jazz Club
- Video Game
- Mono Movie
- 5CH/6CH Stereo
5.1 Multichannel Input: The AVR-1804 is equipped with a 5.1-channel input to accommodate outboard decoders. It has a wide bandwidth of up to 100kHz to accommodate high-resolution audio sources such as DVD-Audio and SACD.
Personal Memory Plus: The Personal Memory Plus function automatically memorizes the surround mode, channel volume, surround parameters, and other settings for each of the separate input sources.
Cinema Equalizer: The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Pro Logic II, Dolby Digital, and DTS surround modes.
Dynamic Range Compression: Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). This only works when playing program sources recorded in Dolby Digital. You can select one of the four settings: "Off", "Low", "Mid" (middle), or "Hi" (high).
Dual Source/Dual Zone Capability: The AVR-1804 allows you to enjoy one program source in a second room while another source is playing in the main room. The Zone 2 output is a stereo pre-amp output, which can send a signal to an amplifier or a set of powered speakers located in another room. The Zone 2 pre-amp output is variable, allowing you to separately adjust the volume with the receiver's remote. In addition, this receiver has a Power Amp Assign function (controlled by a switch on the rear panel), which allows you to assign the amplifier for the Surround Back channel to either the main room or Zone 2. There are two speaker outputs on this channel allowing you to power a pair of speakers in the main room (as Surround Back speakers) or in Zone 2.
Note: The two speakers connected to the Surround Back/Zone 2 terminals will be in mono, not stereo.
Subwoofer Crossover: The cutoff frequency of the subwoofer preamp output is selectable between 80, 100, 120, or 150Hz.
Last Function Memory: This unit is equipped with a last function memory, which stores the input and output setting conditions as they were immediately before the power was switched off.
Back-Up Memory: The unit is also equipped with a back-up memory. This function provides approximately one week of memory storage when the main unit's power switch is off and with the power cord disconnected.
Multibrand Remote: In addition to controlling the AVR-1804 and other Denon A/V components, the supplied remote is pre-programmed to control many brands of A/V components, including DVD players, Video Disc players, VCRs, TVs, cable boxes, DBS (satellite) receivers, CD players, CD recorders, MiniDisc recorders, and tape decks.
Room-to-Room Control: The receiver has a minijack input and output for Room-to-Room Remote Control. These jacks allow you to control other remote-controllable components with an optional Denon IR remote control extender system (RC-16, 17 or 18).
Surround Back/Zone 2 Speaker Outputs: This receiver is equipped with 6 discrete amplifiers, including one for the Surround Back/Zone 2 output. There are two speaker terminals (marked "I" and "II") sharing the Surround Back/Zone 2 amplifier. This allows you to connect 2 speakers in the main zone for the Surround Back channel, or power two speakers in Zone 2. If two speakers are connected, they will be in mono and should have a minimum impedance of 12-16 ohms.
Note: The Power Amp Assign switch on the back of the receiver has to be switched to either "Surround Back" or "Zone 2", depending upon the zone being used.
Speaker Connectors: The AVR-1804 is equipped with binding post connectors for the Left Front A, Right Front A, Center, Left Surround, Right Surround, and Surround Back/Zone 2 speakers. They are not 5-way binding posts because a plastic collar prevents their use with spade lugs and they are positioned too far apart to be used with dual banana plugs. The Front B speakers have spring clip outputs.
Front Panel Inputs: The receiver has a set of A/V inputs on the front panel behind a removable cover. It includes stereo audio RCA jacks, composite and S-Video jacks, and an optical digital jack.
