General Information

1. For additional connection information, refer to the

owner's manual(s) for any component(s) connected

to the MC255.

2. The MC255 mutes the speaker output for approxi-

mately two seconds when first turned on.

3. For the best performance and safety it is important

to always match the impedance of the Loudspeaker

to the Power Amplifier connections. Refer to "How

to Connect" pages 7 and 8.

Note: The impedance of a Loudspeaker actually var-

ies as the Loudspeaker reproduces different

frequencies. As a result, the nominal impedance

rating of the Loudspeaker (usually measured at

a midrange frequency) might not always agree

with the impedance of the Loudspeaker at low

frequencies where the greatest amount of power

is required. Contact the Loudspeaker Manufac-

turer for additional information about the actual

impedance of the Loudspeaker before connecting

it to the McIntosh MC255.

In the event the MC255 over heats, due to improper

ventilation and/or high ambient temperature, the

protection circuits will activate. The Front Panel

Power Guard LED will continuously indicate ON

and the audio will be muted. When the MC255 has

returned to a safe operating temperature, normal

operation will resume.

5. When discarding the unit, comply with local rules

or regulations. Batteries should never be

thrown away or incinerated but disposed

of in accordance with the local regulations

concerning battery disposal.

other McIntosh Products please visit the McIntosh
