Table of Contents
1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected to
the MC205 Power Amplifier.
2. The Main AC Power going to the MC205 and any other
McIntosh Component(s) should not be applied until all
the system components are connected together. Failure
to do so could result in malfunctioning of some or all of
the system’s normal operations. When the MC205 and
other McIntosh Components are in their Standby Power
Off Mode, some of the circuitry inside each compo-
nent is active and communication is occurring between
them.
3. In the event the MC205 overheats, due to improper
ventilation and/or high ambient temperature, the protec-
tion circuits will activate. The Front Panel Power Guard
LEDs will continuously indicate ON and the audio will
be muted. When the MC205 has returned to a safe oper-
ating temperature, normal operation will resume.
