Features

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
  • 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

Set-up:

  • 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
  • Bass/Treble

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

Overview: The supplied remote will control Sony A/V equipment. The source buttons, transport keys, and master volume keys glow in the dark. The factory setting of the function buttons can be changed, except for the TUNER button. The function buttons can be changed to control the following Sony equipment: CD, DAT, MD, Tape Deck A, Tape Deck B, LD player, VCR (VTR settings of 1, 2 or 3), TV, DBS (DIRECTV), DVD, or VCD player.
