Adjusting The Balance Control After The System Has Been Balanced; Adjusting For Special Effects; Listening To Monophonic Fm Program - McIntosh MX 110 Owner's Manual

4. Now switch the INPUT SELECTOR be-
tween FM and PHONO. If the record is louder
than the FM turn the INPUT LEVEL, ADJUST
CONTROL marked PHONO L down (counter-
clockwise). When the loudness of FM and the
record are equal, the left channel level is
correct.
5. Turn the MODE SELECTOR to L+R to R.
6. Again switch the INPUT SELECTOR
between FM and PHONO. If the record is
louder than the FM, turn the INPUT LEVEL
ADJUST CONTROL marked PHONO R down
(counterclockwise). When FM and the record
are equal, the right channel is correct.
Use these same steps to adjust the AUX
input loudness. Remember to compare the
loudness to the FM only. The FM does not
have controls for loudness adjustment.
ADJUSTING BALANCE CONTROL AFTER
THE SYSTEM HAS BEEN BALANCED
When these instructions have been com-
pleted, the overall system is balanced and in
phase; ready to deliver maximum pleasure
and enjoyment.
You may hear differences in balance from
one record to another or from one tape to
another. Some records or tapes may be
recorded with slight differences between
channels. The differences can be corrected
with the BALANCE control on the front panel.
If the difference is heard on every record,
then the cartridge may have a very small
difference in output.

ADJUSTING FOR SPECIAL EFFECTS

HF Cutoff Filter. If you wish to reproduce
old, badly worn records, you can minimize
the surface noise by switching the HF cutoff
filter to the IN position. (See section en-
titled "Front Panel Facilities," page 5.)
LF Rumble Filter. If you are using a turn-
table or changer which has low-frequency
rumble noise, you may reduce it by pushing
the LF rumble filter switch to the IN position.
Bass Controls and Treble Controls. The
tone balance which you hear when listening
to an orchestra is affected by the conductor's
instructions to his musicians, the acoustical
environment m which you are listening, and
your own subjective hearing interpretation.
Considering these conditions, it is easy to see
why tone balance controls play a major role in
correcting for the following factors:
1. Each person's subjective idea of tone
balance.
2. Loudspeaker frequency response char-
acteristics.
3. Loudspeaker placement in the listen-
ing room.
4. The conductor's idea of tone balance
at the time the recording was made.
5. The microphone frequency response
characteristics.
6. The recording process influences.
These factors can be considered as en-
vironmental influences. The BASS controls
and TREBLE controls are designed to provide
a degree of compensation for effects of
environment. Listen to your system with
each control set with the indicators centered
between the panel markings • L and ° R. If
you wish to reduce treble in relation to bass,
turn the TREBLE controls counterclockwise
until the tone balance sounds correct to you.
These controls will modify tone balance with-
out introducing any undesirable effects. Do
not be surprised if you find your preference
in tone changing from time to time.
Loudness. Due to a selective shift in sen-
sitivity of human hearing, music reproduced
at very low volume loses its bass and treble.
The LOUD switch on the MX110 changes
the VOLUME control to a loudness com-
pensated control to correct for this effect.
When you wish to listen to music at a greatly
reduced loudness level and yet hear bass and
treble, set the LOUD switch to the IN position.
Phase. If the stereo sound seems to come
from either side of the room instead of being
distributed between the loudspeakers, adjust
the PHASE control to 180°. This listening
effect is due to reproducing sound that is
out of phase from one channel to the other.
You will find some records differ from others
in this respect and that some tapes differ
from records.
