DSP presets

The digital surround processor provides an extremely comprehensive range of digital signal processing options for decoding both analogue and digital audio signals and processing them for multi-channel reproduction. These are referred to as DSP presets, and 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

Several alternative multi-channel digital formats are currently available which encode up to eight different channels onto a digital signal. Four alternatives are currently in use: Dolby Digital, DTS, MPEG Surround, and MLP. However, the 568 has been designed so that it can be upgraded by downloading a software update, to cater for new formats as they are introduced.

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 an 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.
