panel jacks make connections without having to get 

at the rear panel. When using the front panel jacks, 
the rear panel TAPE 2 facilities are disconnected 

automatically. A metal shielded 1/4 inch stereo 
phono plug is used for best shielding. Connections 

follow the industry standards and are tip: left signal, 

ring: right signal, and, sleeve: common ground. 

HEADPHONES 

The front panel HEADPHONE jack has been 

designed to feed low impedance dynamic head-

phones. Electrostatic headphones generally require 

higher power than dynamic headphones and are 

connected to the output terminals on the power 
amplifier. 

Plug headphones into the front panel HEAD-

PHONE jack. Adjust the front panel VOLUME control 

for comfortable headphone listening. Additional top 
panel HEADPHONE LEVEL controls also adjust the 

loudness of the program when using headphones. 

See the section below for top panel controls. 

An amplifier in the C 29 provides the power that 

feeds both the HEADPHONE jacks on the front 
panel and the LINE OUTPUT jacks on the rear panel. 

Top Panel Controls 

To gain access to the top panel controls depress 

the PANLOC buttons and pull the preamplifier out to 
the adjust position. The controls are now easily 
operated. 

HEADPHONE & LINE OUTPUT 

A control has been provided in each channel to ad-

just the loudness of the program when using head-

phones. The controls adjust the output in each chan-

nel to the HEADPHONE jack only and do not affect 

the program loudness from the loudspeakers. To ad-

just for comfortable headphone listening first adjust 

the VOLUME control to normal room loudness. 

Then, while wearing the headphones, adjust the 

HEADPHONE LEVEL controls to the desired loud-

ness level. 

MAIN OUTPUT LEVEL 

A control has been provided in each channel that 

adjusts the output of the preamplifier. Use these 
controls to compensate for minor differences in 

room effects, loudspeaker efficiency or amplifier 

gain. 

PANLOC 

Mcintosh developed PANLOC mounting brings 

professional installation technique to stereo. 

Depressing the PANLOC button will release the in-

strument. It can then be pulled toward you to the 
"adjustment" position. In this position the top panel 
controls can be adjusted. 

Best stereo performance is achieved when the 

stereo system is properly balanced. For proper 

balance each channel must be equal in loudness. 

Use the top panel level controls to balance system 

loudness. 

This procedure reserves the BALANCE control to 

adjust for any unbalance in the source material, the 

record, etc. 

Before attempting to balance the system make 

certain the front panel controls are set properly. 

Set the MODE SELECTOR to MONO and the 

BALANCE control at the center or 12 o'clock posi-

tion. Turn the tone controls to the center or 12 

o'clock position. The HF - LF pushbuttons should be 

in the OUT position. 

With the tuner turned on, turn up the VOLUME 

control on the front panel until a comfortable room 

loudness is reached. Adjust the top panel MAIN 

OUTPUT LEVEL controls until the loudness from 
each loudspeaker is equal.
