Features

32-Bit Processor: This receiver employs dual 32-bit processors, providing precise surround decoding for Dolby Digital, Dolby Digital EX, DTS, DTS-ES, DTS Neo:6, Dolby Pro Logic, Dolby Pro Logic II, and Dolby Pro Logic IIx, plus Sony's Digital Cinema Sound modes.

Surround Back Decoding: This function lets you select the decoding mode for the surround back signals of the multi-channel input stream. When you select "SB Auto" and the input stream contains 6.1-channel information, the appropriate decoder is applied to decode the surround back signal (Dolby Digital EX, DTS-ES Matrix, or DTS-ES Discrete decoder). When you select "SB On", Dolby Digital EX is applied when the output channel is 6.1 and Dolby Digital EX or Dolby Pro Logic IIx is applied when the output channel is 7.1. When "Off" is selected, no surround back decoding is performed.

Digital Cinema Sound (DCS): Digital Cinema Sound is the concept name of the surround technology for home theater developed by Sony. DCS uses the DSP (Digital Signal Processor) technology to reproduce the sound characteristics of an actual cinema cutting studio in Hollywood. When played at home, DCS will create a powerful theater effect that mimics the artistic combination of sound and action as envisioned by the movie director. The DCS soundfields used in this receiver include:

• Digital Cinema Sound EX A: Reproduces the sound characteristics of the Sony Pictures Entertainment "Cary Grant Theater" cinema production studio. This mode is great for watching most any type of movies.
• Digital Cinema Sound EX B: Reproduces the sound characteristics of the Sony Pictures Entertainment "Kim Novak Theater" cinema production studio. This mode is ideal for watching science fiction or action movies with lots of sound effects.
• Digital Cinema Sound EX C: Reproduces the sound characteristics of the Sony Pictures Entertainment scoring stage. This mode is ideal for watching musicals or films where orchestra music is featured in the soundtrack.
• Headphone Theater: Allows you to experience a theater-like environment while listening through a pair of headphones.

Dolby Pro Logic IIx: Dolby Pro Logic IIx furthers the matrix decoding of Dolby Pro Logic II to decode audio signals recorded on two channels into up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel sources to be played in up to 7.1 channels. The mode can be selected according to the source. There are 3 Dolby Pro Logic IIx modes: Music, Cinema and Game. (The Game mode is for 2-channel sources only.)

Surround Modes: This receiver incorporates a wide variety of surround modes to bring you maximum enjoyment from your audio and video software. The surround modes include:

• Dolby Digital

Headphone Sound Fields: When headphones are connected, you can select the following sound fields:

• HP 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.
• HP Direct: outputs the analog signals without processing by the equalizer, sound field processor
• HP Multi 1/2: outputs the analog signals input to the Multi Channel Input 1 or 2 jacks
• HP Theater (Digital Cinema Sound): allows you to experience a theater-like environment

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

• Front Balance: Left +1 to +16, Center Balance, Right +1 to +16 (33 steps)
• Center Level: -10dB to +10dB in 1dB increments
• Surround Left Level: -10dB to +10dB in 1dB increments
• Surround Right Level: -10dB to +10dB in 1dB increments
• Surround Back Level: -10dB to +10dB in 1dB increments (if only 1 surround back speaker is connected)
• Surround Back Left Level: -10dB to +10dB in 1dB increments (if 2 surround back speakers are connected)
• Surround Back Right Level: -10dB to +10dB in 1dB increments (if 2 surround back speakers are connected)
• Subwoofer Level: -10dB to +10dB in 1dB increments
• Dynamic Range Compressor: allows you to compress the dynamic range of the sound track. You may select standard or maximum compression, or off.
  • Note: This feature only works with Dolby Digital sources.

Auto Format Direct: The Auto Format Direct (A.F.D.) mode allows you to select the decoding mode you want for your audio sound. When you select A.F.D. Auto, the receiver automatically detects the type of audio signal being input (Dolby Digital, DTS, or standard 2-channel stereo) and performs the proper decoding if necessary. You can also select Pro Logic, Pro Logic II Movie, Pro Logic II Music, Pro Logic II Game, Pro Logic IIx Movie, Pro Logic IIx Music, Pro Logic IIx Game, Neo:6 Cinema, or Neo:6 Music to apply the appropriate decoding for movies or normal stereo sources such as CDs.

Analog Direct: Analog direct mode bypasses all digital signal processing for maximum audio purity from any analog source.

Equalizer: You can adjust the tonal quality (bass and treble level) of the front speakers from -10dB to +10dB in 0.5dB steps.

Dual Room/Dual Source Operation: The receiver has a set of fixed-level 2nd zone stereo RCA line outputs, allowing you send analog audio signals to another zone. For the 2nd zone audio source, you can select one of the following sources: MD/Tape, SA-CD/CD, Tuner, or "Source" (the currently selected source in the main zone). Since the 2nd zone line output level is fixed, the 2nd zone audio signal must be fed to a separate amplifier or self-powered speakers equipped with a volume control.

Multi-Channel Inputs: Although this unit features built-in Dolby Digital, Dolby Digital EX, Dolby Pro Logic II, Dolby Pro Logic IIx, and DTS processing, it also has two multi-channel inputs: a 5-1-channel input and a 7.1-channel input for use with external multi-channel decoders.

Video Conversion: The STR-DE997 offers the following video conversion: composite to S-video, composite to component, and S-video to component.

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: You can adjust the brightness of the display in 3 steps.

Remote Control

Learning/Multibrand Remote: The supplied remote is pre-coded to control Sony A/V equipment and most brands of CD players, DAT decks, MD recorders, tape decks, LD players, video CD players, VCRs, DVD players, TVs, DSS receivers, and cable boxes. In addition, this remote can learn up to 80 infrared commands from remotes of other components. A single-line LCD at the top of the remote shows the source currently being controlled. The LCD has an amber backlight that stays illuminated for 3 seconds after a new source is selected.

Macro Play: Up to 2 macros, each with a maximum of 10 steps, can be stored in the remote, allowing you to perform a series of operations at the push of a button.

Inputs and Outputs Notes

Assignable Digital Inputs: The 4 optical digital and 2 coaxial digital inputs are assigned to specific sources (DVD, SA-CD/CD, TV/SAT, VIDEO 3, MD/TAPE). If desired, you can re-assign any of them to the Video 1 or Video 2 inputs.

Front Panel Inputs: The STR-DE997 features a set of front panel inputs with left and right RCA audio jacks, an RCA composite video jack, and an optical digital input.

Speaker Outputs: There are binding post connectors for the Front A left and right, Front B left and right, Center, Surround left and right, and Surround Back speaker outputs. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs. The front A and B speaker pairs are wired in parallel.

SACD Output: No sound is output from the receiver when you play a Super Audio CD on an SACD player connected to the Optical digital input labeled "SA-CD/CD In." You must connect an SACD player via the analog input labeled "SA-CD/CD In" or one of the multi-channel analog inputs.

Control A1 II: The Control A1 II Control System was designed to simplify the operation of audio systems composed of separate Sony components. Control A1 II connections provide a path for the transmission of control signals, which enable automatic operation and control features usually associated with integrated systems. This receiver has a single Control A1 II mini-jack output.

Control S: This receiver has one Control S mini-jack output and one mini-jack input for use with compatible Sony components.

HD Component Video Pass-Through: This unit features 2 component video inputs and a component video monitor output. These jacks feature an 80MHz bandwidth, making them capable of passing high-definition video signals.
