Digital audio connections

Note A digital audio connection will be made into the D1 input if you use the M5- and S5-leads supplied as directed in the section starting on page 46.

Digital audio has to be conveyed to both DSP5000s in the installation.

This can be done directly from your source to each DSP5000 if

∙the source has multiple outputs, or

∙you are using a splitter device

Normally each digital audio source is connected only to the master; the signal from the selected source is then passed from the D OUT socket of the master, via the S5-lead, to the D1 socket of the slave.

Digital connections are made to the master DSP5000:

∙directly from the digital outputs of up to two sources such as CD, DAT, DCC, MD, or the Meridian 604 digital FM tuner

∙from the digital output of an analogue-to-digital converter such as the Meridian 607. A converter like this can be used to process the signals from all your analogue sources (for example, the output of a conventional preamplifier)

∙from the digital output of a digital processor or digital control unit such as the Meridian 562 or 601

∙from the digital output of a Multimedia computing device

Digital connections should be made using high-quality 75Ω screened cable. For advice on the right type of cable to use, we suggest you consult your dealer and the manual supplied with the source equipment.

Meridian has a range of suitable digital interconnects available as accessories. We advise you not to use cables intended for analogue connection, since usually these have neither the necessary degree of shielding nor the 75Ω impedance which is required. Cable intended for UHF applications (for example, antenna down-lead) is also unsuitable, since it does not shield adequately in the 1–30MHz region.

Warning We strongly recommend the use of well-screened precision coaxial cable. Certain ‘audiophile’ cables are not screened. Screened cable will minimise RF interaction with your system. Unscreened cables for digital connections may cause illegal levels of RF interference.

The DSP5000 has two coaxial digital inputs, D1 and D2. The M5- and S5- leads provided, which will be sufficient for the great majority of installations, connect to the D1 input and the D OUT output.

You will need to provide custom cables if

∙you wish to use D1 and D2, or

∙you are wiring a Multiroom installation, or

∙you require cable lengths different from those provided
