GAIN CONTROLS
These controls adjust the input level of the channel
to match the output level of a microphone or instru-
ment connected to input jack of channel 1 or 2.
Control from -10dB to -50dB is possible. Adjust
the output level of the microphone or instrument as
outlined in its instruction booklet.
Low output source,
such as a microphone
CLIP INDICATOR
These LED indicators are provided on channels 1 and 2.
If a CLIP LED lights, the input level to that channel is
too high and is causing clipping distortion. The situation
must be remedied by reducing the setting of the corres-
ponding GAIN control, or by reducing the output level
of the source.
INPUT FADERS
These controls adjust the volume of the signal input, and
send it to the equalizer. Each control is used for set-
ting the sound level of its channel when mixing it with
the signals of other channels. Position "7" on the scale
is considered ideal for the lowest noise and distortion
characteristics.
Input signal
Be sure to set the control to "0" for channels not being
used.
EQUALIZER CONTROLS
These controls are used to adjust the tonal character-
istics of the input signal, or the channel output during
playback of previously recorded material. The LO (low)
controls adjust the frequencies centering around 100Hz,
while the HI (high) controls adjust the frequencies center-
ing around 10KHz, with a 10dB boost or cut range for
both controls. Use of these equalizer controls will help

you to get the type of sound you desire, and allow you
to bring the sound "forward", "clean up" unclear sounds,
and "push down" sounds at annoying frequencies.
In order to properly use these equalizers, it's important
to understand the frequency response characteristics
of various musical instruments. This is particularly true
when trying to "change" the sound of a certain in-
strument, because you should know that instrument's
harmonic sound components as well. For example, the
normal frequency range of a bass drum is between 50Hz
and 150Hz. To bring out this sound so you can feel it
better, the LO (low) control (which centers on the 100Hz
frequency band) can be moved up a little. But the har-
monic sound components are around I0KHz, so the HI

SOUND CHARACTERISTICS OF THE EQUALIZER AND

If accurate and comprehensive sound equalization is
required, connect a graphic equalizer or a parameteric
equalizer between the sound source and the input jack.
When recording material that you intend to "ping-pong"
(see "Ping-ponging" on page 25) later, give the input
somewhat of a high boost with the Hi control to help
preserve the high frequency response when the track is
re-recorded. This technique is known as "pre-emphasis,"
and is commonly used in professional recording.
