DSP presets

The digital surround processor provides an extremely comprehensive range of options for decoding both analogue and digital audio signals and processing them for multi-channel reproduction.

The digital surround processor provides several digital signal processing options, called DSP presets, and these are designed to provide the best results with a range of different types of music and film material.

In addition to selecting built-in DSP presets, the digital surround processor allows you to create your own presets based on the standard ones. For example, you may want to add more delay to the rear speakers to create a more spacious sound. You can store your modified preset with a name of your choice, and recall it for use at a later date.

This section gives information about each of the built-in DSP presets, and gives recommendations for the best preset to choose for different types of material.

Multi-channel digital sources

The 565 Digital Surround Processor supports the three alternative multi-channel digital formats currently available, which encode up to 8 different channels onto a digital signal: Dolby Digital (AC-3), DTS, and MPEG Audio. It also supports Meridian’s own MLP format.

Dolby Digital

Dolby Digital, previously called AC-3, is the preferred sound format for DVD video and is widely used on LaserDisc soundtracks. It is also the audio standard for US digital television.

DTS

DTS uses a carefully designed audio compression technique to encode five channels of audio onto a digital signal. The DTS format is used to encode multi-channel film soundtracks on LaserDiscs and DVD video discs.

In addition, a high data-rate version of DTS can be used to compress five channels of CD-quality audio into the same space as two channels of unencoded sound, allowing a DTS music CD to provide over an hour of five-channel music, at a quality indistinguishable from conventional CD.
