CONTROLS, FEATURES, AND A FEW HELPFUL
HINTS
Before
connecting
and
turning
on
your
MM30,
study the descriptions of its controls and features
given in this section
in order to become familiar
with their basic operation.
It may also be a good
idea to refer to the block diagram at the back of this
FRONT PANEL
manual
to get
an
idea of how
the controls
and
features
fit
in with
the
internal
signal
routing
scheme. The descriptions in this section also include
a number of hints on how, when and why to make
use of the controls.
@
INPUT SELECTOR
This selector has three positions: TAPE, LINE and
MIC.
The
input selector
is set according
to the
source which is required to be fed to the respective
input channel. When a line-level source (600 ohms
to 10 k-ohms, —10 dB nominal) such as an electron-
ic keyboard,
effects
unit
or
a Producer
Series
component
such
as the MR10
Drum
Machine
or
МАТО Headphone Amplifier is connected to one of
the MM30's
INPUT jacks, the input selector should
be set to LINE. If the input source is a microphone,
then the selector should be set to MIC. When per-
forming
a
mixdown
(or "remix'')
from
a four-
channel multitrack tape deck or monitoring from a
stereo cassette deck the input selectors of the appro-
priate channels should be set to TAPE. In this case
the outputs
from
the deck are connected
to the
MM30 TAPE IN jacks.
@
TONE CONTROL
This control gives you basic tonal control over the
source
fed to each channel. Technically speaking,
the tone control is a 10 kHz shelving type with a
+12 dB boost/cut range. When TONE
is set to its
center
position
the overall
frequency
response of
the respective input channel is essentially flat. That
is, the frequency contour of the
input signal is not
altered
in any
way.
Rotating
TONE
clockwise
boosts the high frequency range, thereby creating a
brighter
sound.
Rotating
TONE
counterclockwise
de-emphasizes
the
high
frequency
range, thereby
creating a rounder, more mellow tone. Use the tone
control for overall response tailoring as needed.
