4 MONO CHANNELS SECTION

1 MIC

Neutrik electronically XLR connector

input socket. For connecting low level

signal sources, such as microphones or

other low impedance devices.

2) LINE

B a l a n c e d o r u n b a l a n c e d 1 / 4

(6.35mm)diameter stereo jack input

socket.For connection of high level sound

sources, such as keyboards, electric guitars,

electronic musical instruments or audio

playback units. Mono connectors can also

be used for automatic signal unbalancing.

When connecting a record rurnable , use

only an external R.I.A.A pre-amplifier.

3) INS

Stereo jack connector (

connecting the input and output of a

remote device -noisegate, compresor,

equalizers - in series with the channel. The

command is only avaitable in mono

channels.

4) PAD (-20dB)

When push this switch ,attenuates.the

input signal -20dB.

5) GAIN

Adjusts pre-amplifiction of signals from

the MIC (1)and LINE (2) inputs, ensuring

optimal performance of channel circuits.

For well-balanced Gain adjustment,

position the volum fader (14) at

approximately 3/4 of the control travel,

then adjust Gain until the PEAKLED (10)

lights up only at signal peaks.

6) HIGH-MID-LOW

The sound tone controls are positioned

after the GAIN control (5); the boosting of

these controls can cause channel

overloading , in which case the PEAK

LED will illuminate (10); turn the GAIN

control knob (5) in an anticlockwise

direction until PEAK LED(10)goes out.

HIGH:

controls the high range of signals

( 15dB).

When the knob is centrally

positioned (zero point), sound tone

remains unchanged. Turn the knob

anticlockwise to gradually reduce high

frequencies (vocals with less hiss,

reduction of background noise, cymbals

less cutting,etc.); Turn the knob clockwise

to boost high frequencies (sounds are

highlighted, vocals are more intelligible,

signal harmonics are emphasised).

MID

:controls the mid-range of signals(

12dB). When the knob is centrally positioned

(zero point), sound tone remais unchanged.

Turn the knob anticlockwise to gradually

reduce mid frequencies (reduction of mid part

of sound, tones at extremes of high and low

ranges are emphasised, typical of dance music

tones); tum the knob clockwise to boost mid

frepyencies (sound body is highlighted,

greater overall sound power and more nasal

tone).

LOW

: controls the low range of signals (

15dB). When the knob is centrally positioned

(zero point), sound tone remains unchanted.

Turn the knob anticlockwise to Graduatly

reduce low frequencies (boom is neutralised,

excessively low sounds are removed); turn the

knob clockwise to boost low sounds are

removed); tum the knob clockwise to boost

low freuencies (more fullbodied sound,

highlighting of main signal frequencies,

prcussive sound more pronounced).

7) AUX1-AUX2

Use this control to the level of singal from

extemal soure and the main sigral control is

re-controled by MAS-TER or SUB section.

6.3mm) for

8) EFF1.EFF2

Use this control when you want to get effect

sound by adjustment of input signal, when

you don`t use extemal soure digital will be

working which in stallde inside.

9) PAN

Knob for adjusting signal stereo position, for

constant variation to the stereo image. Turn

the knob to the left (L) or right (R ) to vary the

proportion two signals; turn the knob to far

left

or far right to eliminate the opposite

signal. To connect stereo soures, use two

mono channels; position one PAN to the left

(L), the other to the right (R).

10) PEAK.OdB.-10dB

Red LEDthat lights up when the signal level at

the tone control output is rear clipping

point.yillow LED is odb,green LED is -20dB.

11) PFL

Used for headphone monitoring of each

channel, regardless of the main mix. The

PFL(Pre-Fader Listen) function allows the

user to listen to the level before fader control;

subsequent adjustment of the fader control (14)

will not modify the level. The control is useful

during channel gain adjustment.

12) SUB1-2

Push the switch, can use sub1-2fader.

13)MAIN L-R

If you want to use master L-R fader, push this

switch.

14) FADER

ALPS 60mm slide control, with dust guard

.The fader adjusts channel signal level to be

sent to the Master MAIN controls L- R (41)

.Set the slider to 0dB for maximum signal

level; slide downwards to lower and

eventuaily eliminate (

results, set the slide control to 3/4 of travel

upwards, then adjust the GAIN control (5) to

desired level.
