Some poor speaker designs have input impedances that dip to 1 or 2 ohms at various frequencies. The MC7150 has the output current reserve to drive them.
MC7150 Product Preview/Page 2 THERMAL PROTECTION Thermal sensors that turn off the AC power if improper loading or ventilation causes the amplifier to over heat. TURN ON DELAY The MC7150 has a circuit that delays amplifier operation for about two seconds after turn on. This prevents pops or thumps generated in other equipment from causing annoying noises or damaging your speakers.
MC7150 Product Preview/Page 3 production for which the loudspeakers have been designed. If undersize wire is used, resistance is added to the amplifier/loudspeaker combination which adversely affects the performance. Added resistance causes reduction of damping characteristics, modification of frequency response and reduction in power output. Use lamp cord or wire with similar type of insulation to connect the speakers to the amplifier.
MC7150 Product Preview/Page 4 milliwatts up to 150 watts, the rated power output of the MC7150; the additional indication to the right of the 150 watts mark, is 600 watts. While the MC7150 cannot reach this power level continuously it is possible for short interval peaks to considerably exceed the 150 watts continuous rating. HOLD In the HOLD position, the meter needle locks to the highest power peak in a sequence of peaks.
