Installation

The MC126 can be placed upright on a table or shelf,

standing on its four feet. It also can be custom installed in a

piece of furniture or cabinet of your choice. The four feet

may be removed from the bottom of the MC126 when it is

custom installed as outlined below. The four feet together

with the mounting screws should be retained for possible

future use if the MC126 is removed from the custom instal-

lation and used free

standing. It also can

be custom installed

in a piece of furni-

ture or cabinet of

your choice The re-

quired panel cutout,

ventilation cutout

and unit dimensions

are shown.

Always provide

adequate ventilation

for your MC126.

Cool operation en-

sures the longest

possible operating

life for any elec-

tronic instrument.

Do not install the

MC126 directly

above a heat gener-

ating component

such as a high pow-

ered amplifier. If all

the components are

installed in a single

cabinet, a quiet run-

ning ventilation fan

can be a definite as-

set in maintaining

all the system com-

ponents at the

coolest possible op-

erating temperature.

A custom cabinet

installation should

provide the follow-

ing minimum spac-

ing dimensions for

cool operation. Al-

low at least 6 inches
