About the Sony STR-DE685
Experience all the thrills that 5.1-channel digital home theater has to offer! Sony's STR-DE685 boasts super-precise 32-bit processing to deliver gloriously three-dimensional sound from Dolby® Digital and DTS® soundtracks. You also get Dolby Pro Logic II, which lets you transform Dolby Surround and stereo sources into 5.1-channel sound, and Sony's exclusive Digital Cinema Sound DSP modes, which let you enhance any type of surround soundtrack with the ambience of your choice.
You get plenty of ins and outs to build a great system, including component video switching for 2 sources, 4 digital inputs, a 5.1-channel analog input for an SACD or DVD-Audio player, and more! 100 watts x 5 channels of clean Sony power ensures dynamic multichannel sound. Two sets of main speaker outputs let you hook up stereo speakers in a second room (but you can only play one set at a time). The multibrand remote gives you easy control of your entire A/V system.

Features & specs
- Normal Surround: Normal
Surround includes the following modes:
- Dolby Digital Surround
- Dolby Pro Logic II: Pro Logic II is a new Dolby Laboratories technology that produces surround sound from any stereo source, including CDs, VHS tapes, TV shows, digital audio files like MP3 and AAC, cassette tapes, and FM radio broadcasts. Like Dolby Digital, Dolby Pro Logic II has stereo surround output, giving you a more realistic surround sound experience. Unlike Dolby Digital, Dolby Pro Logic II allows you to enjoy a "5.1-like" presentation using any analog stereo source. There are two Pro Logic II modes, which have been designed to ensure optimal playback of movie soundtracks and music-only sources; you may select Pro Logic II Movie or Pro Logic II Music to match the type of audio being decoded.
- Digital Cinema Sound: This is
a collaboration between Sony Electronics and Sony Pictures where the actual
measurements of the sound acoustics in these studios are taken. This information
is programmed into this receiver so as to simulate the actual theatre in your
home environment. The three DCS fields that you can choose from are:
- Cinema Studio Ex. A: reproduces the sound characteristics of Sony's "Cary Grant Theater" cinema production studio
- Cinema Studio Ex. B: reproduces the sound characteristics of Sony's "Kim Novak Theater" cinema production studio
- Cinema Studio Ex. C: reproduces the sound characteristics of Sony's scoring stage
- Hall: reproduces the acoustics of a rectangular concert hall
- Jazz Club: reproduces the acoustics of a jazz club
- Concert (Live Concert): reproduces the acoustics of a 300-seat live concert
- Game: obtains maximum audio impact from video game software
Note: With each soundfield, you have the ability to adjust the bass, treble, surround effect levels, balance, independent speaker levels, LFE Mix, and Dynamic Range Compression. When adjustments are made, they are automatically stored for that soundfield until you make further adjustments. To retrieve factory settings for the soundfield, just turn the receiver off, and then hold down the power buttin until "SF CLR" appears on the display.
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 coaxial and Toslink digital input jack is compatible with digital signals having a sampling frequency of 96kHz.
Note: Both the coax and Toslink inputs are compatible with 96kHz, 48kHz, 44.1kHz, and 32kHz sampling frequencies
- Front Speakers: you may select "LARGE" or "SMALL"
- Center Speaker: you may select "NO", " LARGE" or " SMALL"
- Surround Speaker: you may select "NO", " LARGE" or " SMALL"
- Subwoofer: you may select "YES" or "NO"
- Left and Right Distance: 3 to 40 feet (1 foot steps)
- Center Distance: whatever the distance set for L and R down to 5 ft less (1 ft steps)
- Surround Left and Right Distance: the distance set for L and R down to 15 ft less (1 ft steps)
- Rear speaker place: when using rear speakers, this setting is used for proper operation of the sound fields that create virtual rear speakers; you may select "SIDE", "MID" or "BEHIND"
- Rear speaker height: you may select the height as either "LOW" or "HIGH"
- C. Mode: your choice of AV1 or AV2
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, depending on the soundfield, up to 15 steps
- Front Balance: the balance can be adjusted +/-8 steps
- Center Level: the level may be adjusted in 1dB steps from -10dB to +6dB
- Surround Left Level: the level may be adjusted in 1dB steps from -10dB to +10dB
- Surround Right 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 +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 can select OFF, 0.1-0.9, in 1 dB steps, STD, and MAX. Enables or disables dynamic compression for less variation in volume
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 3 levels of display brightness, plus you may turn the display off (control from the front of the unit only).
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.
Backup Memory: Once a sound field is customized, the changes are stored in memory indefinitely, unless the receiver is disconnected from power for about 2 weeks. If the receiver is disconnected from power for about 1 week, all of the tuner presets will be cleared from the receiver's memory.Remote Control
