audio system. The MC2301 is equipped with a circuit that provides remote Power Control from a McIntosh A/V Con- trol Center. When the A/V Control Center is switched On, a (5-12V) signal operates the power relay in the MC2301. The MC2301 also has a remote Power Control Out Jack. The Power Control signal from this jack is delayed by a fraction of a second so that the turn on power surge of
