Connecting a Cyrus Surround Sound decoder to the DAC XP
In a Cyrus multi-channel surround sound system the surround decoder may be connected through the DAC XP to share the same front channel power amplifiers.

In this case, connect a stereo phono interconnect from the front channel outputs of the surround decoder to the Input 7 sockets 1# of the DAC XP. For this system to function correctly both the DAC XP and the Cyrus surround decoder must be included in an MC-Bus connection loop and the ‘Cyrus AV’ input name must be set for Input 7 (see ‘MC-Bus’ section and ‘Input names’ in the ‘Setup menu’ section).

When set up in this way, the DAC XP will automatically check for the presence of the decoder when the ‘Cyrus AV’ input is selected, then lock the DAC XP volume setting to an appropriate level
