Sony has loaded the impressive STR-DE985 with everything you need for state-of-the-art 6.1-channel surround sound, plus helpful home theater conveniences galore. Dual 32-bit processors handle Dolby® Digital EX and other 6.1 decoding, DTS®, Dolby Pro Logic™ II, and Sony's exclusive Digital Cinema Sound modes. You also get dual-room/dual source output, so you can enjoy home theater thrills in your main room while a housemate listens to a different stereo source in another room! (Receiver or powered speakers required in the second room.)

The STR-DE985 also gives you plenty of digital and analog inputs for building an impressive system — including front-panel A/V (with S-video) and optical digital inputs for easy hookup of portable equipment. Analog direct modes let you bypass all digital circuity for the cleanest possible sound from analog sources — or from digital sources like DVD-Audio or SACD that you've hooked up via the dual multichannel analog inputs (one 5.1-channel, one 6.1-channel).

The amplifier section delivers 100 watts x 6 channels to render your home theater and music sources with clarity, realism, and impact. You'll also enjoy easy, flexible system control from your couch, thanks to an on-screen display and learning/multibrand remote with macros. Get ready for some serious entertainment! Available in black or silver.

Features

Dual 32-Bit Processors: This receiver incorporates two Digital Signal Processors. Dolby Digital EX, DTS, Dolby Pro Logic II Virtual Matrix 6.1 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.

6.1-Channel Decoding: This unit is equipped to decode 6.1-channel Dolby Digital Surround EX signals. In addition to the standard 5.1 channels, some movies now encode a sixth channel, the surround back. The surround back channel improves the realism of sounds panned across the rear soundstage.

Virtual Matrix 6.1: If you are not using a surround back speaker, 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.

Video Surround Modes:

  • Normal Surround: Normal Surround includes the following modes:
    • Dolby Digital
    • Dolby Digital Surround EX: the Surround EX System allows you to play movies that employ a matrix system to produce 6.1 channels from a 5.1-channel film soundtrack
    • Dolby Pro Logic II: gives you a 5.1-channel effect when playing any 2-channel source. There is a Movie mode that creates a sound space suitable for movies, a Music mode that does the same for music, and a Pro Logic emulation feature that reproduces sound effects in the way that conventional Pro Logic does.
    • DTS
  • Cinema Studio Ex. A: reproduces the sound characteristics of the Sony Pictures Entertainment "Cary Grant Theater" cinema production 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. This is a standard mode, great for watching almost any type of movie.
  • Cinema Studio Ex. B: reproduces the sound characteristics of the Sony Pictures Entertainment "Kim Novak Theater" cinema production 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. This mode is ideal for watching science-fiction or action movies with lots of sound effects.
  • Cinema Studio Ex. C: reproduces the sound characteristics of the Sony Pictures Entertainment scoring stage; 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. This mode is ideal for watching musicals or classic films where music is featured in the soundtrack.
  • 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

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 Concert: reproduces the acoustics of a 300-seat live concert
  • 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 and performs the proper decoding without adding any effects.

Analog Direct: The Analog Direct mode allows you to bypass the internal processors for pure, clean sound.

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 you have connected a speaker to the surround back output.
  • 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" off or on
  • Front Balance: the balance can be adjusted +/-8 steps
  • Center Level: the level may be adjusted in 1dB steps from -10dB to +10dB
  • Surround Level: the level may be adjusted in 1dB steps from -10dB to +10dB
  • Surround Back Level: the level may be adjusted in 1dB steps from -10dB to +10dB
  • Sub Woofer Level: the level may be adjusted in 1dB steps from -10dB to +10dB
  • 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 +10dB, in 1 dB steps

2nd Audio Output: This unit is equipped with stereo RCA jacks to send a fixed level 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 1 or 2 input, you will get no output from the 2nd audio jacks. Additionally, you cannot select Phono as the second audio source.

Component Video Switching: In addition to composite and S-video switching, this unit can switch between two component video sources. There are 2 component video inputs and 1 component video monitor output; each input and output has RCA jacks labeled "Y", "PB/B-Y" and "PR/R-Y". This feature allows you to connect, and switch between, high resolution video sources equipped with component video outputs.

Dual Multichannel Inputs: Although this unit features built-in Dolby Digital, Dolby Digital EX, Dolby Pro Logic II and DTS processing, it also has a 5.1 multichannel input and a 6.1 multichannel input for use with external multichannel decoders.

Station and Source Naming: Each preset station and program source may be given an index name of up to 8 characters.

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).
