Our take on the Sony STR-DE975

Sony

Receivers: Your ticket to sensational sound

Your receiver powers your speakers and lets you connect and select your entertainment sources. But a great receiver does a lot more — it ignites your emotions. From the passion of a favorite musical artist, to the crossfire of a super-charged movie soundtrack, to the intensity and immersion of a fast-paced video game, your receiver is the key to experiencing and enjoying it in full.

Sony loaded their impressive STR-DE975 with all the digital processing you need for state-of-the-art surround sound, plus helpful home theater conveniences galore. Dual 32-bit processors handle all your decoding options. You get 27 soundfields in all — including Dolby® Digital, DTS®, Dolby® Pro Logic™, and Sony's exclusive Digital Cinema Sound™ modes. And you'll love Virtual Matrix 6.1 mode, which creates a pair of "phantom" rear speakers for a 360° wraparound soundstage.

This versatile receiver lets you play one audio source in your main room (CD, surround sound, etc.) while a housemate listens to a different stereo source in another room! (Just connect a shelf system, receiver, amp, or powered speakers in the second room.) The advanced remote control is pre-programmed to operate other brands of A/V gear, plus it can "learn" specific commands from your other remotes. An on-screen display lets you use your TV to keep track of the options you've selected (requires direct video input on TV).

The STR-DE975 gives you plenty of digital and analog inputs for building an impressive, expansive system — including a handy A/V input on the front panel. You even get a 5.1-channel input for SACD and other cutting-edge audio formats. The STR-DE975's amplifier section delivers 110 watts x 5 channels to render your home theater and music sources with clarity, realism, and impact. Get ready for some serious entertainment!

Features

Dual 32-Bit Processors: This receiver incorporates two Digital Signal Processors. Dolby Digital, DTS and Dolby Pro Logic decoding are handled by a dedicated 32-bit DSP engine of superior performance. The Digital Cinema Sound modes and advanced parameter adjustments use a separate 32-bit DSP. This design gives you greater resolution for sound that is realistic and detailed.

Virtual Matrix 6.1: The receiver performs matrix decoding to create a phantom/virtual rear center speaker; this simulates 6.1 channel operation without having an additional speaker in the system. This receiver is not equipped with a surround back speaker output, however, if you are not using a center speaker, you can use the center channel speaker as the surround back speaker.

Video Surround Modes:

  • Normal Surround: Normal Surround includes the following modes:
    • Dolby Digital/Dolby Pro Logic: Dolby Digital sources are played with as many channels as recorded; 2-channel stereo sources are decoded with Dolby Pro Logic
    • DTS
  • Cinema Studio Ex. A: reproduces the sound characteristics of Sony Pictures Entertainment's classic editing studio; uses the 3D sound imaging of the Virtual Multi Dimension mode to create 5 sets of virtual surround speakers from one pair of actual surround speakers
  • Cinema Studio Ex. B: reproduces the sound characteristics of Sony Pictures Entertainment's mixing studio; uses the 3D sound imaging of the Virtual Multi Dimension mode to create 5 sets of virtual surround speakers from one pair of actual surround speakers
  • Cinema Studio Ex. C: reproduces the sound characteristics of Sony Pictures Entertainment's BGM recording studio; uses the 3D sound imaging of the Virtual Multi Dimension mode to create 5 sets of virtual surround speakers from one pair of actual surround speakers
  • Semi Cinema Studio Ex. A: reproduces the sound characteristics of Sony Pictures Entertainment's classic editing studio; uses the 3D sound imaging of the Virtual Semi Multi Dimension mode to create 5 sets of virtual surround speakers surrounding the listener using only the front left and front right speakers
  • Semi Cinema Studio Ex. B: reproduces the sound characteristics of Sony Pictures Entertainment's mixing studio; uses the 3D sound imaging of the Virtual Semi Multi Dimension mode to create 5 sets of virtual surround speakers surrounding the listener using only the front left and front right speakers
  • Semi Cinema Studio Ex. C: reproduces the sound characteristics of Sony Pictures Entertainment's BGM recording studio; uses the 3D sound imaging of the Virtual Semi Multi Dimension mode to create 5 sets of virtual surround speakers surrounding the listener using only the front left and front right speakers
  • Night Theater: allows you to retain a theater-like environment while listening at low volume levels
  • Mono Movie: creates a theater-like environment from movies with monaural soundtracks
  • Stereo Movie: creates a theater-like environment from movies recorded with stereo soundtracks
  • Virtual Multi Dimension: uses 3D sound imaging to create an array of virtual rear speakers positioned higher than the listener from a single pair of actual rear speakers. This mode creates 5 sets of virtual speakers surrounding you at approximately a 30-degree angle of elevation
  • Virtual Multi Rear: uses 3D sound imaging to create 3 sets of virtual rear speakers from one set of actual surround speakers
  • V.Semi-M. Dimension: uses 3D sound imaging to create virtual rear speakers from the sound of the front speakers without using actual rear speakers. It creates 5 sets of speakers surrounding the listener at a 30-degree angle of elevation.
  • Virtual Enhanced A: uses 3D sound imaging to create 3 sets of virtual rear speakers from the sound of the front speakers
  • Virtual Enhanced B: uses 3D sound imaging to create 1 set of virtual rear speakers from the sound of the front speakers

Audio Surround Modes:

  • Digital Concert Hall A: reproduces the sonic characteristics of the Concertgebouw in Amsterdam, which is famous for its large sound stage due to its reflectivity
  • Digital Concert Hall B: reproduces the sonic characteristics of the Musikverein in Vienna, which is famous for its hall resonance and unique reverberations
  • Church: reproduces the acoustics of a stone church
  • Opera House: reproduces the acoustics of an opera house
  • Jazz Club: reproduces the acoustics of a jazz club
  • Disco/Club: reproduces the acoustics of a dance club
  • Live House: reproduces the acoustics of a 300-seat live house
  • Arena: reproduces the acoustics of a 1000-seat concert hall
  • Stadium: reproduces the feeling of a large open-air stadium
  • Game: obtains maximum audio impact from video game software

Headphone Audio Modes: When headphones are connected, you can select the following sound fields:

  • 2CH: outputs the sound in stereo. Standard 2-channel sources completely bypass the sound field processing. Multi-channel surround formats are downmixed to 2-channels.
  • Direct: outputs the analog signals without digital processing
  • Theater: allows you to experience a theater-like environment

Auto Format Decoding: Automatically detects the type of audio signal being input (Dolby Digital, DTS, Dolby Pro Logic, 2-channel) and performs the proper decoding without adding any effects.

96kHz Sampling Frequency Compatibility: The DVD/LD coaxial and DVD/LD optical digital input jacks are compatible with 96kHz, 48kHz, 44.1kHz and 32kHz sampling frequencies.

Note: The TV/SAT and MD/DAT Toslink optical digital input jacks are not compatible with digital signals having a sampling frequency of 96kHz; sound may be intermittent if a digital signal with a sampling frequency of 96kHz is input to the TV/SAT and MD/DAT optical digital inputs.

Bass Management:

  • Front Speakers: you may select "LARGE" or "SMALL". When the front speakers are set to "SMALL", the center, surround back and surround speakers are automatically set to "SMALL".
  • Center Speaker: you may select "NO", "LARGE", or "SMALL". If the front speakers are set to "SMALL", the center speaker cannot be set to "LARGE".
  • Surround Speakers: you may select "NO", "LARGE" or "SMALL". If the front speakers are set to "SMALL", the surround speakers cannot be set to "LARGE".
  • Surround Back Speaker: you may select "NO", "LARGE", or "SMALL". This parameter can be set when the center speaker is set to "NO" and the surround speakers are set to "LARGE" or "SMALL". This allows you to use the center channel speaker as the surround back speaker.
  • Subwoofer: you may select "YES" or "NO"
  • Subwoofer Phase Polarity: you may select "NORMAL" or "REVERSE"
  • Surround Speaker Position: when using rear speakers, this setting is used for proper operation of the sound fields that create virtual rear speakers; you may select "SIDE", "MIDDLE" or "BEHIND"
  • Surround Speaker Height: you may select "LOW" or "HIGH"
  • Front Speaker Crossover: When the front speakers are set to "SMALL", you can adjust the front speaker bass crossover frequency from 40Hz to 200Hz in 10Hz increments
  • Center Speaker Crossover: When the center speaker is set to "SMALL", you can adjust the center speaker bass crossover frequency from 40Hz to 200Hz in 10Hz increments
  • Surround Speaker Crossover: When the surround speakers are set to "SMALL", you can adjust the surround speaker bass crossover frequency from 40Hz to 200Hz in 10Hz increments
  • Surround Back Speaker Crossover: When the surround back speaker is set to "SMALL", you can adjust the surround back speaker bass crossover frequency from 40Hz to 200Hz in 10Hz increments
  • LFE High-Cut Filter: allows you to adjust the LFE high-cut frequency from 40Hz to 200Hz in 10Hz increments
  • Test Tone: the test tone feature allows you to independently adjust the volume level of each channel

Sound Field Customizing: Depending on the Mode selected, you can adjust the following parameters:

  • Effect Level: the "presence" of the surround effect may be adjusted in 21 steps (0 - 20)
  • Wall Type (wall material simulation): 17 steps from hard to soft
  • Reverberation Time: may be adjusted in 17 steps
  • Front Reverberation: when using Digital Concert Hall A or B, you can select "WET" to increase front reverberations, or "DRY" to decrease front reverberations
  • Screen Depth: this feature allows you to adjust the sound so it appears to be coming from inside your TV screen; you may turn this feature off, or it may be set to "MID" or "DEEP"
  • Virtual Speakers: allows you to turn the virtual speakers created by "Cinema Studio EX A, B, C" and "Semi Cinema Studio EX A, B, C" off or on
  • Front Balance: the balance can be adjusted +/-8 steps
  • Surround Balance: the balance can be adjusted +/-8 steps
  • Center Level: the level may be adjusted in 1dB steps from -10dB to +6dB
  • Surround Level: the level may be adjusted in 1dB steps from -10dB to +6dB
  • Surround Back Level: the level may be adjusted in 1dB steps from -10dB to +6dB
  • Sub Woofer Level: the level may be adjusted in 1dB steps from -10dB to +6dB
  • LFE Mix: lowers the level of the LFE channel output. You may select "OFF" (mute), or the level may be set from -20 to 0dB in 1dB steps. Note that this effects only the LFE channel, not the bass sent to the sub through bass redirection circuitry.
  • Dynamic Range Compressor: you may select standard compression, maximum compression or a compression level from 0.1 to 0.9, in 0.1 steps; the dynamic range compressor feature may be turned off. When active, the dynamic range compressor feature compresses the audio output so there is less variation in volume from Dolby Digital sources; this feature does not work with DTS sources
  • EQ: you may select one of 23 treble frequencies (ranging from 1kHz to 10kHz), one of 37 mid frequencies (ranging from 198Hz to 10kHz), and one of 21 bass frequencies (ranging from 99Hz to 1kHz) for each channel. You can adjust the level of those frequencies from -10dB to +6dB, in 1 dB steps

2nd Audio Output: This unit is equipped with stereo RCA jacks to send a stereo audio signal to a receiver or amplifier in another room. The same source or different sources may be played in the main room and the 2nd room. Only signals from components connected to the analog input jacks are passed through the 2nd audio output jacks. Note: If "2nd Room" is set to "Source" and you select the Multi CH input, you will get no output from the 2nd audio jacks. Additionally, you cannot select Phono as the second audio source.

Multi Channel Input: Although this unit features built-in Dolby Digital and DTS processing, it also has a 5.1 multi-channel input for use with external multi-channel decoders, including potential future units such as multi-channel SACD players and DVD Audio players. 

Station and Source Naming: Each preset station and program source may be given an index name of up to 8 characters. For example, two VCRs can be displayed as 8MM and VHS.

Sleep Timer: The unit may be set to automatically turn off after 2 hours, 1 hour and 30 minutes, 1 hour, or 30 minutes.

Dimmer: There are 4 levels of display brightness, plus you may turn the display off (control from the front of the unit only).
