The MCX-CA15 features three different operation modes for user flexibility. Before using the MCX-CA15,
you must set the operation mode to either “A”, “B” or “C” depending on your system configuration.
Be sure to set the operation mode before connecting the MCX-CA15 to a live power source.
■Operation Modes
*For details on the input level sensing function, see page 11.
In “B” and “C” modes, you cannot adjust the volume level from the MCX-CA15. Signals
input through the AUDIO IN jack are not converted before being output. If loud sounds are
output, your speakers may be damaged. Before listening to components for the first time,
lower the volume on the component to minimum.
• In “B” mode, if no signal is detected for five minutes or longer, the MCX-CA15 enters sleep mode.
• In “B” and “C” modes, when a component is connected to the AUDIO IN jack, the input default setting is
“AUDIO IN”. However, when no component is connected, the default setting is “AV IN”.
• Before connecting or disconnecting an external component to/from the AUDIO IN jack, be sure to unplug
the MCX-CA15 from a live power supply.
