MC-12 is powered on, the standby button can be used to
activate and deactivate standby mode. When the MC-12 is
powered off, standby mode is not available.

2. AC Input Connector

Provides power to the MC-12 through the supplied power cord
(3 wire, 10 amp, IEC 320).

3. Digital Audio Input Connectors (S/PDIF & AES/EBU)

Provide digital audio input in all zones. Six S/PDIF coaxial,
six S/PDIF optical (TosLink), and one AES/EBU (XLR) input
connectors are available. These connectors are compatible with
PCM (44.1, 48, 88.2, and 96kHz), Dolby Digital, and dts(-ES)
sources. These connectors are not compatible with MPEG or
MP3 sources.

4. Analog Audio Input Connectors

Provide analog audio input in all zones. Eight stereo analog
audio input connectors labeled 1 to 8 are available. The
connectors labeled 6, 7, and 8 can be configured as a 5.1-
channel connector.
When a 5.1-channel analog audio source is present in the Main
Zone, input signals are sent to the Main Zone audio output
connectors as indicated in the table at the top of the next
column. When a 5.1-channel analog source is present in the
Main Zone and the INPUT SETUP menu ZONE2 IN or RECORD
IN parameter is set to DMIX, only the (L) and (R) input
signals are sent to the Zone 2 or Record Zone audio output
connectors.
