GENERAL DESCRIPTION 

The MX 114 combines in one unit an ex-

tremely low-distortion preamplifier with a 

highly sensitive FM multiplex tuner. The 

INPUT SELECTOR gives you a choice of 

five different program sources. 

The Mclntosh MX 114 is a beautifully 

engineered tuner/control center for the 

finest stereo sound systems. 

The MX 114 is completely solid state, with 

the exception of the tuning indicator. The 

solid state devices used in the MX 114 

are products of the latest technology of 

solid state physics. 

The extreme care in manufacturing, in 

layout design and in quality control prom-

ises the usual Mclntosh extra values of 

reliability, performance, and long life. 

Other values added to this tuner are: 

careful control of circuit constants dur-

ing testing, very high sensitivity and ex-

cellent spurious response rejection. 
Every desirable feature of a tuner and 

preamplifier is included in this design. 

FM interstation noise suppression (mut-

ing), tuning indicator, FM multiplex indi-

cator, individual channel bass and treble 

controls and electronic phase switch 

have all been engineered into the MX 114. 

The Mclntosh designed PANLOC system 

is the first professional installation tech-

nique to be used on stereo instruments. 

The PANLOC system gives you ease of 

installation, operation and maintenance. 
By releasing the PANLOC buttons on the 

front panel, you can slide the MX 114 out 

of its mounting until the second latch en-

gages. The top mounted controls for 

interstation noise suppression (muting), 

phase switching and front panel lighting 

are now available.
