[. . . ] LISTENING TO A STEREO TAPE RECORDER Turn the INPUT SELECTOR to TAPE. Set the MODE pushbutton to STEREO or MONO, depending on the program on the tape. Adjust the VOLUME control to desired volume. TO RECORD ON A STEREO TAPE RECORDER All program sources are available at the TAPE OUTPUT jacks. The program material is unaffected by all front panel controls except the INPUT SELECTOR, and the use of the SELECT button on AM and FM. To monitor while recording, the tape recorder must have separate record and playback or monitor heads. The TAPE pushbutton permits monitoring the tape recordings while in the process of recording. When the TAPE pushbutton is at the IN position it will play the sound from the tape as it passes the playback head, a moment after it is recorded. The recording process continues as usual. When the TAPE pushbutton is at the OUT position the program being recorded is heard. LISTENING TO AM Turn the INPUT SELECTOR to AM. Rotate the tuning knob to the station of your choice. Adjust the volume to a comfortable level. Separation of a weak station from a strong adjacent station can be improved with the SELECT button at the IN position. LISTENING TO FM OR FM STEREO Turn the INPUT SELECTOR to FM. Rotate the tuning knob to the station of your choice. Separation of a weak station from a strong adjacent station can be improved with the SELECT button at the IN position. When the STEREO indicator is lighted, the station is broadcasting a 19, 000 Hz pilot signal for stereo and the MX 113 will automatically switch to stereo. If a station is not transmitting the 19, 000 Hz pilot signal for stereo, the STEREO indicator will remain off and the tuner will automatically switch to mono. The MX 113 uses a new Mclntosh developed automatic mono-stereo switching circuit. The circuit action is electronic and prevents switching clicks or transients. The ultrasonic muting circiut suppresses all noise between FM stations. It also suppresses all weaker stations not strong enough to override the background noise. [. . . ] This circuit provides equal amplitude signals but of opposite phase for the phase switch. The filter networks can be switched in or out. The highfrequency filter network reduces treble response above 5, 000 Hz. The low-frequency filter reduces bass response below 50 Hz. [. . . ]
