MCINTOSH MC2300 AMPLIFIER

MCINTOSH MC2300 AMPLIFIER. This amplifier is completely stable when connected to any loudspeaker system and to any reactive loads. The MC 2300 has special circuits to prevent damage by short circuit or open circuit of the output loads, or by any amount of output impedance mismatch. Full power and full power response at all speaker impedances comes from a McIntosh development, the MCINTOSH TRIFILAR UNITY COUPLED AUTOFORMER. Using a McIntosh developed trifilar winding technique, and careful interleaving of the windings makes the autoformer a near perfect matching device for all loudspeakers, dynamics and electrostatic. Reliability and long trouble free life comes, in part, from McIntosh Sentry Monitoring Circuits. The SENTRY MONITORING CIRCUIT prevents failure of the power transistors due to excessive mis-match of the output. With the amplifier operating normally the SENTRY MONITORING CIRCUIT has no effect on the signals passing through the power amplifiers. If the power dissipation should rise above normal, the SENTRY MONITORING CIRCUIT restricts the drive voltage to the output transistors. The SENTRY MONITORING CIRCUIT acts instantaneously. You are assured of complete circuit reliability. McIntosh is the only amplifier with this degree of protection. Thermal cutouts are mounted on the output transistor heat sinks to provide protection in the event of inadequate ventilation. Peak reading—peak locking meters feature special circuits that respond to the peak values of complex input signals.
