Important Information
1. Connecting Cables are 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 MA6500
Integrated 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 16 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 50 feet (38.1m) or less,
use 14 Gauge (AWG) wire size or larger.
If your loudspeaker cables are 100 feet (76.2m) or less,
use 10 Gauge (AWG) wire size or larger.
5. In the event that the MA6500 Integrated Amplifier over
heats, due to improper ventilation and/or extremely high
ambient temperature, the built in protection circuits will
activate. The MA6500 Front Panel Power Guard LED’s will
both continuously indicate On and the audio output signal
will be muted. When the temperature of the MA6500 has
returned to a safe condition, sound will return and the Power
Guard Indicators will return to normal operation.
