NOTES:
1. The following Connecting Cable is available from the
McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo mini
phone plugs on each end.
2. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the MC352
Amplifier.
3. There is a built-in turn on delay which will mute the speaker
outputs for approximately two seconds when the amplifier is
turned on.
4. It is very important that loudspeaker cables of adequate size
be used in your music system, to ensure that there will be no
power loss or heating. Cable size is specified in Gauge
numbers or AWG, (American Wire Gauge). The smaller the
Gauge number, the larger the wire size:
If your loudspeaker cables are 25 feet (7.62m) or less,
use at least 16 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 50 feet (38.1m) or less,
use at least 14 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 100 feet (76.2m) or less,
use at least 12 Gauge (AWG) wire size or larger.
5. Pin configuration for the XLR Balanced Input connectors on
the MC352: PIN 1: Shield or ground.
PIN 2: + input.
PIN 3: - input.
6. In the event that MC352 Power Amplifier over heats, due to
improper ventilation and/or extremely high ambient
temperature, the built in protection circuits will activate. The
MC352 Front Panel Power Guard LED’s will both
continuously indicate On and the audio input signal will be
muted. When the temperature of the MC352 has returned to
a safe condition, sound will return and the Power Guard
Indictors will return to normal operation.
