DESCRIPTION The McIntosh Model Mc-30 is a 30 watt high fidelity power amplifier designed for home entertainment systems and professional applications. The Model Mc-30 is similar to the earlier McIntosh Model A-116 30 watt amplifiers and includes all of the rigid electrical specifications and features found in these earlier units plus: less than 0.3% harmonic distortion at any power output up to 30 watts and at any frequency in the audio spectrum, 20 to 20,000 cps; less than 0.
the octal "Pre-Amp input" receptacle. In this case connect the input lead to pin #5 and the ground lead to pin # 1. When using this connection the source must not have a DC 6utput component. Output Connections The Mc-30 has output impedances of 4, 8 and 16 ohms available at either the screw terminal connector or the output socket. In addition, a 600 ohm output (balanced to ground) is available at the output socket. See schematic diagram for socket connections.
Power Output 30 watts continuous Input Level Input # 1 (pin jack and screw terminals and pin 5 of pre amp socket) .5 volts to 30 volts, with gain control Input #2 (pin 2 of pre amp socket) 2.5 volts, (For use with McIntosh preamplifier equipment). Frequency Range 20 to 30, 000 cycles + . 1 db at 30 watts output 15 to 50,000 cycles + .5 db at 30 watts output 10 to 100,000 cycles ~ 1 db at 15 watts output Harmonic Distortion Less than 1/3% at 30 watts output or less, 20 to 20,000 cycles.

DESCRIPTION The McIntosh Model MC-30 is a 30 watt high fidelity power amplifier designed for home entertainment systems and professional applications.
If desired, the signal source may be wired to an octal plug for insertion in the octal "Pre-Amp input" receptacle. In this case connect the input lead to pin #5 and the ground lead to pin # 1. When using this connection the source must not have a DC output component. Output Connections The MC-30 has output impedances of 4, 8 and 16 ohms available at either the screw terminal connector or the output socket. In addition, a 600 ohm output (balanced to ground) is available at the output socket.
GUARANTEE We guarantee the performance of this equipment and the mechanical and electrical workmanship to be free of serious defects for a period of 90 days. This guarantee does not extend to components damaged by improper use nor does it extend to transportation to and from the factory. SERVICE INFORMATION All Mcintosh equipment IS designed for long trouble free operation. All components are of highest quality and are conservatively operated.
