1080p-compatible HDMI switching and component video conversion
If you've got an HDTV with only one HDMI input, you'll appreciate this receiver's 1080p-compatible HDMI switching. Hook up your HD satellite receiver and a high-def disc player via HDMI and switch between them, while maintaining pristine picture and sound quality for both. Component video conversion allows you to route all of your analog video sources to your TV using only one component video connection. This simplifies hookup, streamlines switching, and maintains the best picture for every analog video source in your system.

Easy, accurate speaker setup
Denon also included Audyssey MultEQ®, a sophisticated auto-calibration system that helps you get the most accurate home theater sound possible. Just plug in the included microphone and place it in up to six different seats in your home theater room. The '1908 analyzes the sound from each listening position, then automatically adjusts level, equalization, and delay settings for each of your speakers. You get precise surround sound across a wide listening area.

Simple operation and multi-room versatility
You get a multibrand remote with glow-in-the-dark keys, for convenient control of every component in your system. The '1908's icon-based on-screen display puts receiver menus on your TV screen to simplify system setup and navigation. And dual-room/dual-source capability lets you enjoy home theater in your main room while a housemate listens to music in another room — this receiver can even power stereo speakers in your second room.

works super with PS3's - DTS-MA or True HD!!!!!

dgjr from temple,TX on 4/16/2008

Crutchfield Customer Review (What's this?)

This units rocks the house! I got a few weeks ago. When I found out about PS3's - DTS-MA I was rethinking buying this until I got some info on how it works. The Denon 1908 shows "MULTI CH IN" on the display and gives no indication that I can see of doing DTS-MA. its just like True HD. PS3 is set to output LPCM. If i hit the select button on my PS3 it shows DTS-MA or True HD,but on the display of the Denon 1908 shows "MULTI CH IN". This is because the PS3 is doing the decoding. That's fine with me as long as it's doing it. DirecTV HD box and PS3 hooked up to the 1908 via HDMI and then to the TV and it switches between the two nicely. Audyssey (Auto Setup)sets your speakers and tailors them according to you room. This unit is a safe buy 2 me.

Two-channel Music Modes: There are two 2-channel playback modes exclusively for music:

Pure Direct: Plays back music with an extremely high level of sound quality. All the video-related circuits are turned off so that music signals are reproduced with high quality. When an analog mode is selected, the digital processing circuits are also turned off to achieve the highest purity.
Audio signals bypass the tone control circuits, and are transmitted directly, resulting in good quality sound.
Allows you to adjust the tone to achieve the desired sound.

Personal Memory Plus: The receiver has a personal memorization function that automatically memorizes the surround modes and input modes selected for the different input sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled. The surround parameters, tone control settings, and playback level balance for the different output channels are memorized for each surround mode.

Surround Parameters: You can adjust the following surround mode parameters:

CINEMA EQ (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 (including PL II and PL IIx), Dolby Digital, DTS Surround, DTS Neo:6, and Wide Screen modes.
D.COMP (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 or DTS. You can select one of the four settings: "OFF", "LOW", "MID" (middle), or "HI" (high).
This setting adjusts the low-frequency effects level (LFE). You can adjust the LFE from -10 to 0 dB.
Center Image:
This function assigns a center channel signal to the front left and right channels for wider sound. You can adjust the center image range from 0.0 to 0.3 to 1.0.

Center Width: This function assigns a center channel signal to the front left and right channels for wider sound. You can select from 0 to 3 to 7.
Delay Time:
This feature adjusts the delay time to control the sound stage size. You can select either 0 to 30ms to 300ms.
Effect Level:
This function adjusts the effect signal level from 1 to 10 to 15.
Room Size:
This feature determines the size of your acoustic environment. You can select from Small, Medium small, Medium, Medium large, or Large.
This feature auto-selects the surround mode by the connected source's content.
SB CH Out (for multi-channel sources):
This setting selects the playback mode for the surround back channels of the receiver. You can choose from Non Matrix, Matrix, PLIIx Cinema, PLIIx Music, ES Matrix, ES Discrete or Off.
SB CH Out (for 2-channel sources):
You can select either On or Off for the surround back channels when listening to a 2-channel source.

Tone Settings: You can independently adjust the system's overall Bass and Treble settings from -6 to +6 dB.

Subwoofer Level: The receiver's subwoofer level can be adjusted from 0, 5, 10 or 15 dB.

Night Mode: This mode is optimized for late night listening. You can select from the following Night Modes - Low, Middle, High or Off.

Restorer: This function restores compressed audio signal to how they were before compression and corrects the sense of volume of the bass to obtain richer playback sound. You can select from one of the following modes - Mode 1, Mode 2, Mode 3 or Off.

Auto Setup: The receiver is equipped with an Auto Setup and Room Equalization function, to achieve the most ideal sound field for your room. The AVR-1908 Audyssey MultiEQ function is designed to optimize the sound quality at each listening position in the room. The included DM-A405 microphone is used to measure test tones at each listening position. This measured data is then analyzed using a program to improve acoustic characteristics in the listening area. For best results at least 6 positions should be measured, including a main position. The main position is given more weight in the calculations. The Audyssey function adjusts the following measurements automatically: Speaker Configuration, Distance, Channel Level, Crossover Frequency, and Room EQ.

Room EQ:The Room EQ function offers the following adjustments:

Audyssey: Adjusts the frequency response of all speakers to correct the effects of room acoustics.
Audyssey Byp. L/R:
Optimizes frequency response of speakers except front speakers to match room acoustics.|
Audyssey Flat:
frequency response of all speakers are flat.
Manual EQ:
This feature adjusts the tonal quality for each speaker using the receiver's built-in graphic equalizer. You can select -20 to +6 dB for the following frequencies for each speaker - 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2khz, 4kHz, 8kHz, and 16kHz.
Turns equalizer off.

Manual Speaker Setup: The receiver also allows you to adjust the following speaker parameters manually.
