PUSHBUTTONS 

MODE SELECTOR: STEREO: The left 

channel is heard  f r o m the left  l o u d -

speaker and the right channel is heard 

from the right loudspeaker. 

MONO (L + R): The left and right chan-

nels are added together and are heard 

from both loudspeakers. 

LF FILTER: With the push button pushed 

in the low frequency response is attenu-

ated below 50 Hz. The slope is 6 dB per 

octave. Use of the LF filter reduces un-

wanted low frequency noise such as 

rumble. With the push button released, 

the response of the MX 114 is flat. 

HF FILTER: With the push button pushed 

IN the high frequency response is attenu-

ated above 5 kHz. The slope is 6 dB per 

octave. Use of the HF filter reduces un-

wanted high frequency noise like hiss or 

scratch. With push button released, the 

response of the MX 114 is flat 

TAPE: The TAPE push button is used to 

monitor tape as it is being recorded. With 

the push button IN, the recorded tape is 

heard. Release the button and the pro-

gram being recorded is heard. Instan-

taneous comparison of recorded material 

and the program source is provided by 

the use of the TAPE push button. 

IMPORTANT: When the MX 114 is oper-

ated with the TAPE push button in the 

IN position, signal from any other source 

will not be heard from the loudspeakers. 

When not in use make sure the push but-

ton is in the "OUT" position. 

MUTING: Muting suppresses the back-

ground noise and hiss normally heard 

between stations. With the control in the 

IN position the muting is turned on. Weak 

stations that may not override noise and 

interference are also suppressed by the 

muting. In the OUT position, the muting 

is  f u m e d off. This allows conventional 

FM tuning with the noise and interfer-

ence present. Use this position to tune 

weak or noisy stations. 

LOUD: When the volume is reduced, the 

music will seem to lose much of its bass 

and some of its treble. This effect is due 

to the sensitivity characteristic of human 

hearing. The response of the human ear 

to bass and treble pitch decreases more 

rapidly than its response to notes cen-

tered in the mid-tonal range. The LOUD 

control automatically provides the cor-

rect amount of bass and treble boost re-

quired to compensate for this change in 

response of the human ear at low-loud-

ness levels. The LOUD converts the vol-

ume control to a loudness compensated 

control. Use the LOUD IN to listen at low 

volume and still hear  f u l l - f r e q u e n c y 

range. 

PANLOC 

Mclntosh developed PANLOC mounting 

brings professional installation tech-

nique to stereo. Depressing the PANLOC 

buttons (as with a ball point pen) will 

release the instrument. It can then be slid 

forward to the "adjustment" position. In 

the "adjust" position the top panel con-

trols PHASE, MUTING and DIAL SCALE 

INTENSITY can be adjusted.
