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 6.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel sources to be played in up to 6.1 channels. The mode can be selected according to the source. There are 3 Dolby Pro Logic IIx modes; Music, Cinema and Game.

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, Neo:6 Music, or Multi Stereo to apply the appropriate decoding for movies or normal stereo sources such as CDs.

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 (5.1 or 6.1)
• Dolby Digital EX (6.1)
• Dolby Pro Logic
• Dolby Pro Logic II (Movie, Music, and Game)
• Dolby Pro Logic IIx (Movie, Music, and Game)

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

• Headphone 2CH: outputs the sound in stereo, 2-channel sources bypass the sound field processing, multi-channel surround formats are downmixed to 2 channels
• Headphone Direct: outputs analog signals with no sound field or tone processing
• Headphone Multi: outputs the analog signals input to the Multi Channel Input jacks
• Headphone Theater (Digital Cinema Sound): allows you to experience a theater-like environment

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 and the output is 6.1. When "Off" is selected, no surround back decoding is performed.

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

• Front Balance: Left +1 to +8, Center Balance, Right +1 to +8 (17 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
• Subwoofer Level: -10dB to +10dB in 1dB increments
• Dynamic Range Compressor: allows you to compress the dynamic range of the sound track, select standard or maximum compression, or off (only works with Dolby Digital sources)
  

 Digital Decoding: You can choose auto decoding or PCM for the digital audio inputs. Auto will decode the signal in its original form (Dolby Digital, DTS, PCM, etc), PCM decodes the signal to 2-channel.

Speaker Setup: The Speaker Setup menu allows you to set the size, distance from your seating position, and location of the speakers connected to the receiver. The following adjustments are available:

• Subwoofer: Yes, No
• Front Speakers: Large, Small
• Center Speaker: Large, Small, No
• Surround Speakers: Large, Small, No
• Surround Back Speaker: Yes, No
• Front Speaker Distance: 3 to 23 feet in 1 foot steps
• Center Speaker Distance: range is from the front speaker distance setting to 5 feet closer than the front speaker distance setting
• Surround Left Speaker Distance: range is from the front speaker distance setting to 15 feet closer than the front speaker distance setting
• Surround Right Speaker Distance: range is from the front speaker distance setting to 15 feet closer than the front speaker distance setting
• Surround Back Speaker Distance: range is from the front speaker distance setting to 15 feet closer than the front speaker distance setting
• Surround Speaker Position: set based on the location of the surround speakers, side low, side high, behind low, behind high
• Crossover Frequency: set crossover point for speakers set to small, choose 40, 60, 80, 90, 100, 110, 120, 140, or 160 Hz

Auto Calibration: The STR-DG500 is equipped with Digital Cinema Auto Calibration Technology which uses the included microphone to automatically check the speaker connections, adjust the speaker output levels, and calculate the distance from each speaker to the listening position. Note: The auto calibration feature does not measure or adjust the subwoofer level output.

A/V Sync: The audio output can be delayed so that the time gap between the audio output and the visual display is minimized. This is especially helpful when you are using a large LCD or plasma TV or a projection TV. The delay is 68 ms when A/V Sync is turned on.

Bass/Treble: You can adjust the tonal quality (bass and treble level) of the front speakers from -6dB to +6dB in 1dB steps.

Multi-Channel Input: 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 a 5.1-channel input for use with an external multi-channel decoder (SACD, DVD-Audio, etc). When using the multi-channel input the STR-DG500's speaker set up circuitry is bypassed, so all bass management and speaker level adjustment must be made on the connected component.

Tuner: The STR-DG500 has 30 presets each for AM and FM, for a total of 60. In addition to preset and auto tuning, stations can be tuned directly by frequency.

Two Channel Mode: The 2 channel button sets the receiver to power only the front left and right speakers, no surround and no subwoofer. 2 channels sources bypass the sound field processing and multi channel sources are down-mixed to 2 channels.

Analog Direct: The direct feature amplifies the source without any processing, only the volume and front speaker balance adjustments are active.

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 30, 60, 90, or 120 minutes.

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

Remote Control

Audio/Video Remote: The supplied remote is pre-coded to control this Sony receiver and several other Sony components, including VCRs, DVD players, DVD recorders, CD players, MD recorders, cassette decks, hard disc recorders, and satellite receivers.

Inputs and Outputs Notes

Front Panel Inputs: The STR-DG500 features a set of front panel inputs with left and right RCA audio jacks and an RCA composite video jack.

Speaker Outputs: The front A left and right, center, surround left and right, and surround back speaker terminals are binding post connectors. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs, but they will accept bare wire, single banana, and dual banana plugs. The front B left and right connections are spring terminals. The front A and B speaker pairs are wired in parallel.,

Multi Channel Input: Six analog RCA inputs are used for outboard 5.1 channel processors. Note: The signal connected to the multi-channel input is not output to the MD/Tape or Video 1 analog audio outputs.

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 or Coaxial digital input. You must connect an SACD player via the analog SACD input or the multi-channel analog input.

Assignable Component Video Inputs: The receiver has 2 component video inputs which can be assigned to specific sources such as VIDEO 1, SACD, AUX, MD/Tape, etc.

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

Digital Inputs: The 1 coaxial digital and 2 optical digital inputs will support 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz sampling frequencies.

Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.
