  • DTS Express: DTS-Express is a low bit-rate encoding technology supporting up to 5.1 channels with fixed data transfer rates.
  • Neural Surround: Neural Surround has been adopted by XM Satellite Radio for digital radio broadcasts of XM HD Surround recordings and live events in surround sound. Neural Surround employs psychoacoustic frequency domain processing which allows delivery of a more detailed sound stage with superior channel separation and localization of audio elements.
  • Dolby Pro Logic IIz Height: Dolby Pro Logic IIz Height is designed to more effectively use existing program material when height channel speaker outputs are present. Dolby Pro Logic IIz Height can be used to upmix a variety of sources from movies and music, but are particularly well-suited to up-mix game content.
  • Dolby Pro Logic IIx: Pro Logic IIx expands any existing stereo- or 5.1-channel audio for a 6.1- or 7.1- channel playback, creating a seamless, natural surround sound-field that immerses you in the entertainment experience. Dolby Pro Logic IIx has 5 modes:
    • Movie: This mode provides 6.1 or 7.1 channel surround sound from Dolby Surround, encodes stereo movie soundtracks.
    • Music: The Pro LogicIIx-Music mode creates a rich and enveloping ambience from stereo sources such as CDs. In this mode, the SR6004 includes three controls to fine tune this sound-field.
      • Panorama: Panorama wraps the sound of the front left and right speakers around you, for an exciting perspective.
      • Dimension: This feature adjusts the sound-field either towards the front or towards the rear of your system. This can be useful to help achieve a more suitable balance from all the speaker with certain recordings.
      • Center Width: The Center Width feature allows you to gradually spread the center channel sound into the front left and right speakers.
    • Game: This mode restores the impact low-frequency surround effects by routing them to the system's subwoofer.
  • Circle Surround II (Cinema/Music/Mono): Circle Surround is designed to enable multi-channel surround sound playback of non-encoded and multi-channel encode material. Backward compatibility provides listeners with up to 6.1 channels of surround performances from an entire collection of music and film, including broadcast, video tape, and stereo recorded music. Depending on source material , you can select Cinema, Music or Mono mode. Circle Surround also offers the following parameter adjustments.
    • TruBass: TruBass produced by your speakers is an octave below the actual physical capabilities of your speakers adding exciting, deep bass effects.
    • SRS Dialog: This feature allows dialogue to easily be discerned from the surround audio effects.
  • Dolby Virtual Speaker: Dolby Virtual Speaker technology use proprietary technology of Dolby Laboratories to create a virtual surround sound-field using only two speakers for the front channels, allowing the user to experience sound as if surround speakers were actually being used.
  • Dolby Headphone: This mode simulates the waveforms of the actual sounds heard from the speakers when listening to the receiver's audio through a connected pair of headphones.
  • HDCD: When listening to HDCD recordings, you hear more dynamic range, a focused 3-D sound stage, and extremely natural vocal and musical timber.
  • Source Direct: In the Source Direct mode, the tone control circuit and bass management configuration are bypassed for full-range frequency response and the purist audio reproduction.
  • Pure Direct: The Pure Direct mode further reduces sources of noise in addition to effect of the Source Direct mode, by blocking output from the video jacks and turning of the unit's display.
  • Stereo: This mode bypasses all surround processing. In stereo program sources, the left and right channels play normally when PCM audio or analog stereo is input. With Dolby Digital and DTS sources, the 5.1 channels are converted to two channels stereo. 96kHz PCM source material can be played back in stereo mode.
  • Multi-Channel Stereo (Music or Movie): This mode is used to create a wider, deeper and more natural soundstage from two channel source material. This is done by feeding the left channel signal to both left front and left surround speakers and the right channel signal to both right front and right surround speaker. Additionally, the center channel reproduces a mix of the right and left channel.

Auto MultEQ Setup: This Audyssey MultEQ technology adapted by this receiver provides the best listening environment for multiple listeners. The Auto MultEQ Setup feature of the SR6004 measures sound characteristics of your speaker system and room where the receiver is used and automatically optimizes settings. To do this, the Auto Setup feature measures a test tone emitted by each channel in a maximum of 6 listening positions, using the supplied microphone. The measurement results are analyzed using an original algorithm and environmental settings are made to improve the sound characteristics of your listening area.

Note: If you prefer, you can manually setup up your speaker configurations. You can select the size and presence of each speaker, the distance of each speaker from your normal listening position, and the level of each speaker in your system.

Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics. Audyssey Dynamic EQ works in tandem with Audyssey MultEQ to provide well-balanced sound for every listener at any volume level.

Audyssey Dynamic EQ Adjust: Audyssey Dynamic EQ is referenced to the standard film mix level of 85dB SPL for -20 dBFS. Due, to the lack of standard outside the film industry, the film reference level may not be appropriate when listening to other material. Audyssey Dynamic EQ Adjust provides three offsets from the film level reference (5dB, 10dB, or 15dB) that can be selected when the mix level of the content is not within the standard.

Audyssey Dynamic Volume: Audyssey Dynamic Volume solves the problem of large variations in volume level between television programs, commercials, and between the soft and loud passages of movies. Audyssey Dynamic EQ is integrated into Dynamic Volume so that as the playback volume is adjusted automatically, the perceived bass response, tonal balance, surround impression, and dialogue clarity remain the same. The amount of compression can be set to an of the following three levels - Light, Medium, or High.

Acoustic EQ: The A/V receiver features 5 Acoustic Equalizer modes to choose from.

  • Audyssey: This mode adjust the frequency characteristics of all speakers so as to create the best listening environment for the sound characteristics of your listening area.
  • Front: This mode matches the characteristic of each speaker to those of the front speakers.
  • Flat: This mode flattens the frequency characteristics of all speakers. It is suited for playback of multi-channel music such as Dolby Digital and DTS.
  • User: This mode independently adjusts the receiver's 9-band graphic equalizer (63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz) for each of the 7 channels.
  • Off: The graphic equalizer is not use.

HT-EQ: The tonal balance of a film soundtrack will be excessively bright and harsh when played back over audio equipment in the home. This is because film soundtracks were designed to be played back in large movie theater environments. Activating the receiver's HT-EQ feature when watching a film made from movie theaters corrects this and restores the correct tonal balance.

Surround Channel Level: The channel level can be independently set for Multi-Channel Stereo, CSII and other modes. You can adjust the Center level, Surround level and Surround Back level from -12 to +12 in 0.5 dB increments. The Subwoofer level can be adjusted from -18 to +12 in 0.5 dB increments.

LFE Level: This function selects the output level of the LFE signal included in the Dolby Digital signal or the DTS signal. You can select from 0 to -10 dB.

Night Mode: Useful at night or when loud noise is undesirable, this mode compresses the dynamic range, making it easier to hear quieter audio content without increasing the overall volume of your system. Night Mode is only effective for Dolby Digital content.

M-DAX: This function makes up for lost audio content in MP3 or AAC sources during playback.

Zone System: The SR6004's Zone System mode allows the same audio source or different audio sources to be heard in other rooms other than where the receiver is installed. The Marantz AV receiver features a Main Audio/Video Zone (Main), a second analog Audio Only Zone (Zone A) and a digital Audio Only Zone (Zone B). The Main Zone contains 7.1-channel playback of your audio/video gear in your main entertainment room. The Audio Only Zone A allows analog audio playback of another audio source connected to the receiver in another room of your home via left/right RCA audio output connections to a separate amplifier. The Audio Only Zone B allows digital audio playback of another digital audio source connected to the receiver in another room of your home via an optical digital output connected to a separate amplifier. The SR6004 AV receiver's Surround Back Speaker outputs can be assigned to Zone A so you can power a set of speakers in another room of your home without the use of a separate amplifier. You must turn off the Surround Back channels of the amplifier when using the receiver's multi-room speaker outputs, which will limit you to 5.1 channels in your main room.

Bi-Amp Connection: A bi-amp connection is possible with speakers that have two sets of inputs by combining the Front A and Surround Back speaker connections. This allows you to drive the treble and bass units with separate channels amps, which enable better sound quality. The surround back channels of the amplifier will need to be turned off to bi-amp your front speakers. This configuration will limit your Home Theater to 5.1- channel.

Digital Inputs/Output: There are 2 coaxial digital inputs and 4 optical digital inputs (one on front). The inputs accept digital audio signals from a compact disc, LD, DVD or other digital source component. There is also 1 optical digital output. The digital output can be connected to MD, recorders, CD recorders, DAT decks, or other similar components.
