Meridian Audio 565 Planning sources, Using an analogue preamplifier, Using a Digital Control Unit

Planning sources

The 565 provides three audio inputs: analogue, digital-cable, and digital-optical. These inputs will allow you to set up a surround system with the following sources, without the need for an additional preamplifier:

❍CD or DVD connected to the digital-cable input.

❍TV connected to the analogue input.

❍LaserDisc, connected to the digital-optical input.

Using an analogue preamplifier

Alternatively, the 565 can be used in conjunction with an analogue preamplifier, such as the 501 or 501V Control Unit, connected to the 565 analogue input. In this case digital sources, such as a LaserDisc or CD, should be connected directly to the appropriate 565 digital inputs. The 501 and 501V Control Units allow up to six analogue sources to be connected to the 565, each with adjustable sensitivity.

Introduction

Using a Digital Control Unit

For greatest flexibility, and optimal performance, the 565 should be used in conjunction with the Meridian 562 or 562V Digital Control Unit. In this case all the source selection and switching is performed by the Digital Control Unit. The 562 and 562V Digital Control Units provide an on-board analogue to digital converter, allowing up to seven analogue sources to be connected to the 565, each with adjustable sensitivity, combined with up to seven digital sources to provide a pure digital feed to the 565.

Using a LaserDisc player

Some early LaserDiscs are recorded with analogue soundtracks, or provide different information on the analogue and digital soundtracks, so to take advantage of these you will need to connect a LaserDisc player to both a digital and an analogue input.

If you have a 7.1 version of the 565 you can take advantage of Dolby Digital LaserDiscs by connecting the LaserDisc player to the 565 via a 519 Demodulator; see To connect to a 519 Demodulator, page 15.
