Listening to Your Stereo
LISTENING TO A STEREO RECORD
Turn the INPUT SELECTOR to PHONO 1 or PHONO 2,
whichever is connected to the record player you wish
to hear.
Make certain the MODE PUSHBUTTON is in the OUT or
STEREO position.
Adjust the VOLUME control to desired volume.
LISTENING TO A MONOPHONIC RECORD
Turn the INPUT SELECTOR to PHONO 1 or PHONO 2,
whichever is connected to the record player you wish
to hear.
Push the MODE pushbutton IN to MONO.
Adjust the VOLUME control to desired volume.
LISTENING TO A STEREO TAPE RECORDER
Turn the INPUT SELECTOR to TAPE.
Set the MODE pushbutton to STEREO or MONO, depend-
ing 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 re-
corded 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 cir-
cuit. The circuit action is electronic and prevents switching
clicks or transients.
The ultrasonic muting circiut suppresses all noise be-
tween FM stations. It also suppresses all weaker stations
not strong enough to override the background noise. The
muting threshold setting determines the strength of the
signal which can be heard with muting in operation. Casual
adjustment of the muting threshold is not recommended.
While tuning FM you may notice that the tuning meter
will show a station yet no program is heard from the
speakers. The muting circuit in the tuner has rejected the
station because there is objectionable noise with the weak
signal from the station. Push the MUTING pushbutton to
the OUT position and the station will be heard. Most pro-
grams that can be tuned in this manner are of poor quality
due to interfering noise.
The ability to separate a weak station from a strong sta-
tion will be improved by the use of the SELECT push-
button. With the pushbutton at the IN position a Mclntosh
developed circuit compresses the sides of the IF curve
which improves the separation of weak stations from strong
stations on adjacent channels.
