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

High out-

put source,

such as an

keyboard

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.

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

5

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

(high) control should also be moved up a little to achieve

the proper sound profile of the bass drum.

VARIOUS MUSICAL INSTRUMENTS

components

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.
