The TX-DS595’s surround sound enables you to enjoy the presence of a movie theater or concert hall in your room.
The configuration of the speakers are very important for the surround sound. Refer to “Connecting speakers” on page 15.
Before using a listening mode, make sure the Speaker Setup parameters have been set (refer to page 19) . Once the parameters have been set, it is not necessary to set them again. Refer to page 25 for information regarding how to select the listening mode.
Listening modes
Stereo
This mode has all input sounds output from the left and right front speakers.
Direct
This mode delivers pure sound with minimum sound quality adjustment and filtration. The sound recorded for the right and left front channels is output to the right and left front speakers only and not output to the subwoofer.
Surround modes
With this mode, decoding is performed automatically to match the input signal. This original mode adds no sound processing to the input signal.
•Dolby D (Dolby Digital)
Digital data with AC-3 compression and a maximum of 5.1- channel* surround sound. This source signal comes from DVDs
and LDs that have the 
mark and therefore recorded for 5.1- channel output. This source also comes from digital satellite broadcasts that support Dolby Digital.
•DTS
DTS (Digital Theater System) is compressed digital data with a maximum 5.1-channel* surround output that allows for an extremely high-quality sound. This source signal requires a
DVD player that supports DTS output and comes from compact discs, DVDs, and LDs that have the 
mark.
Notes on DTS:
•If you play a CD or LD that supports DTS when the “ANALOG” setting is selected on the TX-DS595, the DTS encoded signal will not be decoded and noise will be output. This noise could damage the amplifier and speakers. Therefore, be sure to selected “AUTO” and use the digital input jacks (OPTICAL or COAXIAL) to connect the DTS source.
•The DTS indicator on the TX-DS595 lights while a DTS source is played. When playback finishes and the DTS signal transmission stops, the TX-DS595 remains in DTS mode and the DTS indicator remains lit. This prevents noise when you operate the pause or skip button on the player. Therefore, if the source is immediately switched from DTS to PCM, the PCM signal may not be played. In this case, stop the playback of the source on the player for about three seconds and then resume playback.
•If you press the pause or skip button on the player while playing a DTS source, on rare occasions a short noise may be heard. This is not a malfunction.
•You may not be able to play some DTS source signals from certain CD players and LD players even if you connect the player to the TX-DS595 digitally. This is because the digital signal has been processed (such as the output level, sampling frequency, or frequency response) and the TX-DS595 cannot recognize the signal as DTS data. Therefore you may hear noise when you play a DTS source while processing the signal.
•The outputs for the VIDEO 1 OUT and TAPE OUT output analog audio signals. Do not record from CDs or LDs that support DTS using these outputs. If you do, the DTS-encoded signal will be recorded as noise.
*The 5.1-channel digital surround format has a variety of versions including Dolby Digital and DTS. The 5.1- channel digital surround format enables you to individually record and play five full-range (20 Hz to 20 kHz) channels (left and right front, center, and two surround channels) plus an LFE channel (Low Frequency Effect) for the low-range effect sound. It will create a realistic sound that can be heard in the theaters and concert halls.
•DOLBY PRO LOGIC II Surround
This mode is a new generation 5-channel surround system that provides performance between the 4-channel (left front, right front, center, and monaural surround) Pro Logic Surround and the 5.1-channel Dolby Digital Surround. This mode can be set to the Movie mode designed for playing movies and the Music mode designed for listening to music. In the Movie mode, the surround channels, which used to provide monaural output over only a narrow frequency range, now provide complete stereo output over the full frequency range. The result is movie viewing with a realistic feel of movement. The Music mode uses the surround channels to provide a natural sound space that cannot be provided with normal stereo output.
This mode can be used with VHS and DVD videos with the
mark and certain television programs. The Music mode can be used with music compact discs and other stereo sources.
You can press the SURR button on the remote controller to switch between MOVIE and MUSIC. The initial setting is MOVIE. This setting can be made for each input source.
If no surround speakers are connected, then the surround sound is divided and output from the front left and right channels (3 stereo).
Re-EQ function
You can use the Cinema Re-Equalization function when playing back sources in the Dolby Digital and Dolby Pro Logic II Movie modes (see page 9).
LATE NIGHT
When using Dolby Digital, you can use the LATE NIGHT function (see page 32).
Orchestra
This mode is appropriate for classical and opera music. The center channel is cut and the surround channels are emphasized to widen the stereo image. It will simulate the natural reverberation that is created in large halls.
TV Logic
This mode gives realistic acoustics to TV programs that are aired from TV studios. It enhances the entire surround sound and clarity of the conversation.
Unplugged
This mode is suitable for acoustical instrumental sounds, vocals, and jazz music. By emphasizing the front stereo image, it will simulate the acoustics that you would experience in front of the stage.
Studio-Mix
This mode is for rock and popular music. The lively sounds are enhanced for a powerful acoustic image that simulates the feeling of being in a club or rock concert.
All Ch Stereo
This mode is designed for playing background music. The front, surround, and surround back channels create a stereo image that encompasses the entire area.
