You specify whether you are using the digital or analogue output for each channel in the Speaker Set configuration option; see Setting up the speaker outputs, page 28. Note that you should always leave the unused analogue or digital output for each channel unconnected.

The analogue connections should be made using high-quality screened cable, taking care to connect the left and right channels correctly.

The digital connections should be made with high-quality 75Ω screened cable. Suitable cables are available from Meridian. We do not recommend using analogue audio cables, which do not have adequate shielding or the correct impedance, or cables intended for UHF applications, as these do not provide adequate shielding in the 1–30MHz region.

Optical connections should be made using a suitable optical fibre supplied by your dealer.
