Liner Notes

The Mclntosh MR 75 AM-FM Stereo Tuner is a superb tuner using the latest high technology circuits. This fine tuner will discover more FM stations with good quality than ever before. The Automatic Frequency Lock (AFL) is a patented Mclntosh circuit that activates when you tune to the center frequency of an FM station. When the center ON-STATION vertical LED indicator lights, there will be no drift from accurate tuning, insuring minimum distortion and best performance. When listening to weak or distant FM stations, optimum stereo separation and signal to noise ratio is automatically provided by a third generation phase locked loop stereo decoder.
