Using the Front Panel Controls
In Mclntosh loudspeakers the characteristics of
the speaker enclosure and the characteristics of the
loudspeaker mechanisms have been combined to
produce nearly perfect transient response. The de-
sign for excellent transient response has to com-
promise the system low frequency response. The
most effective means of recovering a flat low fre-
quency characteristic is the use of an electrically
equalized speaker input signal. The Mclntosh En-
vironmental Equalizer does this job. Conventionally
designed loudspeakers should not be used with the
MQ 101 since it will overdrive them, distorting the
sound and decreasing their useful life expectancy.
Mclntosh loudspeakers should not be used with other
equalizers since they are designed for other applica-
tions and will not produce the low intermodulation
characteristic and the proper frequency balance
which is so important to Mclntosh sound.
When a Mclntosh Environmental Equalizer is prop-
erly connected in the stereo system all program ma-
terial at all outputs except the tape output will be
equalized.
TAPE MONITOR
The TAPE MONITOR is used only when the MQ 101
has been connected to the tape monitor facilities of
the source equipment. The control is used in exactly
the same fashion as the tape monitor control on the
source equipment.
LOW FREQUENCY
A five position concentric switch selects from five
different low frequency equalization curves, inde-
pendently, in each channel. The outer knob adjusts
the right channel response. The center knob adjusts
the left channel response. Use low frequency equali-
zation to compensate for the placement of the loud-
speaker in your room. Position 1 modifies low fre-
quency response least and position 5 has the great-
est effect on low frequencies.
MID FREQUENCY
A five position switch selects from five different
mid frequency equalization curves for both channels.
Use mid frequency equalization to compensate for the
effects of room acoustics and furnishings on the mid
frequencies. Positions one and two select curves that
decrease the amount of mid range loudness and
positions four and five select curves that increase the
amount of mid-range loudness. Position 3 is electri-
cally flat.
HIGH FREQUENCY
A five position switch selects from five different
high frequency equalization curves for both chan-
nels. Positions one and two select curves that de-
crease the high frequency loudness and positions
four and five select curves that increase the high
frequency loudness. Position 3 is electrically flat.
PANLOC
Mclntosh developed PANLOC mounting brings pro-
fessional installation technique to stereo. When the
MQ 101 has been installed on PANLOC brackets,
pressing the PANLOC buttons locks the equalizer
firmly in. Depressing the buttons (as with a ballpoint
pen) releases the instrument. The equalizer can then
be slid forward for easy removal.
