marked MONO INPUT. This jack is located
below the right control knob marked GAIN.
The input sensitivity in this position is 0.5
volt. The GAIN control should be adjusted to
match the input voltage sensitivity of the
MC275 to the output voltage of the program
source.
For maximum flexibility set the GAIN con-
trol as follows: turn the volume control on
the program source equipment (i.e. tape
recorder, tuner, preamplifier, etc.) to the
12 o'clock (half rotation) position. Turn the
GAIN control on the MC275 until the loud-
ness of the sound from the speaker is just a
little louder than you normally like to listen.
The volume control on the program source
equipment now has the most convenient
amount of loudness change in either direc-
tion from the 12 o'clock position.
