3 2. The MC301 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 8 thru 11. 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 MC301. 4. In the event the MC301 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 MC301 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. 6.
