Surround sound modes, Dolby Digital | Cambridge Audio 340Razur

Surround sound modes

The 340R has several music and home-cinema listening modes available. Before we describe how to operate the 340R, below is a brief guide to surround sound formats:

Dolby Digital

Known also as DD (3/2) or DD 5.1, provides (up to) 5.1 output from suitable encoded Dolby Digital material, with 5 main channels (Front Left, Front Right, Centre, Surround Left, Surround Right) and a Low Frequency Effects Channel for the subwoofer, all discretely encoded. Decoding Dolby Digital requires a Dolby Digital encoded DVD disc and a digital connection from the source equipment (Such as a DVD player) to the 340R.

Note: Dolby Digital and DTS formats can sometimes carry less channels than their maximum such as Dolby Digital (2/0) which means a Dolby Digital encoded signal which is actually only carrying a two channel stereo signal (other channels inactive).

DTS

Known also as DTS (3/2) or DTS 5.1, DTS provides (up to) 5.1 output from suitable encoded DTS material, with 5 main channels (Front Left, Front Right, Centre, Surround Left, Surround Right) and a Low Frequency Effects Channel for the subwoofer, all discretely encoded. Decoding DTS requires a suitably encoded DTS disc and a digital connection from the source equipment to the 340R.

Pro Logic II

The replacement for original Pro Logic, Pro Logic II is a technology where 5 channels (Front Left, Front Right, Centre, Surround Left, Surround Right) are encoded into a Stereo mix by an analog matrix process. Dolby Pro Logic II material can be played back by normal Stereo equipment (as Stereo) or decoded into 5 channel surround-sound.

Dolby Pro Logic II is compatible with the earlier 4 channel (Left, Centre, Right and mono Surround) Dolby Pro Logic system (which was the decoding counterpart to Dolby Surround encoding) as used widely on Video tapes, TV broadcasts and earlier films.

Note: Pro Logic does not include a Low Frequency Effects channel for the Subwoofer, but the 340R can create a Subwoofer output (for 5.1) via Bass management. Refer to the ‘Advanced bass management’ section in the ‘Operating instructions’ part of this manual.

Dolby Digital EX

Known also as DD (3/3) or DD 6.1, an enhanced form of Dolby Digital. On top of the normal discretely encoded 5.1 channels DD EX provides an extra 6th channel (Surround Back) matrix encoded into the rear surrounds. As DD EX 6.1 is backwards compatible with DD 5.1 the 340R can play back DD EX material as 5.1. The 6th Surround Back signal is then present in both Left and Right Rear Surrounds forming a phantom rear centre.

DTS-ES 6.1 Matrix, DTS-ES 6.1 Discrete

Enhanced forms of DTS which also encode an extra 6th channel (Surround Back) into the rear surrounds. Both DTS EX Matrix and DTS EX Discrete are backwards compatible with DTS 5.1 so the 340R can play back DTS ES Matrix or Discrete material as 5.1, the 6th Surround Back signal being present in both Left and Right Rear Surrounds as a phantom rear centre.

DSP modes

These modes allow a realistic surround-sound experience from source material that has no encoding at all. The surround sound effect is achieved by Digital Signal Processing of the Analog or Digital stereo source used. Five modes are possible: Movie, Music, Room, Theatre and Hall.
