    Use shielded single conductor cable with RCA type connectors. Connect a cable from the LEFT channel of a preamplifier output to the L (left) INPUT jack on the MC7100. Connect the RIGHT channel preamplifier output to the R (right) INPUT jack on the MC7100.

    The plug blades are polarized; so be certain the plug is fully inserted in the outlet to prevent blade exposure. (The MC7100 has no AC power switch, so it must be switched on and off by a preamplifier or other accessory component.) Make certain that the AC outlet used can supply at least 6 amperes of current.

  • Page 15: Technical Description

    All power transistors have limits for the maximum amount of power they can handle. The MC7100 output transistors and power supply have been designed to allow very high current flow into properly matched load impedances. However, if a short circuit or very low load im- pedance is connected to the MC7100 outputs, destructive current levels could be reached if it was not controlled by the SENTRY MONITOR circuit.
  • Page 16 A unique and patented feature of Mclntosh power amplifiers insures that each channel of the MC7100 will deliver full power, free of clipping distortion. Clipping occurs when an amplifier is overdriven past its output design capabilities. An overdriven amplifier can pro- duce both audible and ultrasonic distortion levels approaching 40%.
