INPUT SELECTOR 

AUX: Any program source requiring flat amplification 

is connected to the AUX jacks on the back panel. 

TAPE: The output of a tape recorder with its own 

electronics is connected to the TAPE jacks on the 

back panel. 

FM: For listening to the FM section of the MX 114. 

PHONO 1: The output of a record player or turntable 

is connected to the PHONO 1 jacks on the back 

panel. 

PHONO 2: The output of another record player or 

turntable is connected to the PHONO 2 jacks on 

the back panel. 

TREBLE: Modifies the high frequency program ma-

terial to suit your taste. The right channel is the 

large knob, the left channel is the small knob. 

BASS:

 Modifies the low frequency program material 

to suit your taste. The right channel is the large 

knob, the left channel is the small knob. 

BALANCE:

 Adjusts for equal loudness in each chan-

nel when the program source has unequal channel-

to-channel volume. 

VOLUME ON/OFF:

 Turns the MX 114 "ON" and ad-

justs loudness of the sound. 

PUSHBUTTONS: 

MODE SELECTOR: Push IN for MONO; OUT for 

STEREO. 

HF: Push IN: Reduces high frequencies to sup-

press unwanted record noise, etc.; OUT: Flat 

response. 

LF: Push IN: Reduces low frequencies to suppress 

unwanted rumble; OUT: Flat response. 

TAPE: Push IN: Monitor the recorded program 

from the tape. Push OUT: Hear the program that 

is being recorded. 

MUTING: in the IN position the muting is turned on. 

Weak stations that may not override noise and 

interference are suppressed by the muting to the 

OUT position, the muting is turned off. This allows 

conventional FM tuning with the noise and inter-

ference present. Use this position to tune weak 

or noisy stations. 

LOUDNESS: Push IN: Adjusts bass as volume is re-

duced to compensate for average hearing losses 

at low volume.
