MC-BUS SYSTEM CONNECTION

The MC-Bus system (see drawing on page 4) can provide
unified power control of a complete Cyrus system from
your Cyrus aCA7. MC-Bus connections are wired as a
'loop' with single RCA phono interconnects. The diagram
below shows a typical Cyrus system of Cyrus CD Player,
Cyrus FM7Cyrus aCA7 and Cyrus Power Amplifier with
the MC-Bus loop connected. Connect the first cable
between the MC-Bus output 

c

 of the Cyrus aCA7 and the

MC-Bus input of the next Cyrus component. Continue to
wire each MC-Bus output to the next input, returning to
the Cyrus aCA7 input to complete the loop.

OPERATION WITH MC-BUS CONNECTED

When MC-BUS connections have been made it is possible
to control the power function of the entire system from the
Cyrus aCA7.
For example, if you select 'CD' from either the Cyrus
aCA7
 front panel or the Audio Commander, you will
switch on the Cyrus aCA7, the Cyrus CD player and any
connected Cyrus Power amplifiers.
When the Cyrus aCA7 is set to Standby, all system
components will also switch off.
