Output signal
The EQ is a device used to change the volume and structure of a sound
signal. This is likely to create distortions harmful to your equipment
distribution. Always make sure that the output of your EQ is clear, without
distortion, and an acceptable level for downstream devices. Indeed, a simple
check of the output volume is not sufficient. A saturated signal, even at an
acceptable level, can damage your equipment or create hearing problems.
4-General Characteristics
Stereo equalizer 2x15 band with inputs/outputs balanced and unbalanced
– 19-inch rack.
The EQ is a professional tool for changing the sound level by frequency
bands and thus change the look of a sound source, by reducing or
increasing parts of the spectrum.

3-Preparation
3.1-Check the contents of the pack
The package must contain the following:
- The EQ
- The user guide
- 1 power cord
3.2-Installation of the device
a. EQ installs on a flat surface or in a rack mount kit provided for this purpose.
b. Make sure the unit is installed in a properly ventilated area and where it will
not be exposed to direct sunlight, or in excessively high temperatures or
high humidity.
5-Front and Rear Panels
5.1-Front
5.2-Rear
1. Power button -
This button to turns the unit on or off.
2. Power indicator -
This LED lights up when the EQ is in working condition.
3. Key IN/OUT -
This button, once pressed, bypasses the EQ section.
4. Faders frequency setting -
These faders allow you to adjust each
frequency with an effective range of +/-12dB. The value of the
frequency is indicated about each fader, and is expressed in Hertz (Hz).
5. Output gain -
This potentiometer controls the gain of the total output of
the EQ. This setting is particularly useful to catch the fall or rises in level
due to this type of treatment. Adjustment range is -12dB/+12dB.
6. Output Level Bar Graph -
These 4 LEDs indicate the output level.
Each LED illuminates when the signal reaches the level that
corresponds to it. Values are expressed in dB. When +10 and +17 LED
indicators light up, the risk of saturation is high.
7. Low Cut -
This button will activate the low-cut integrated equalizer.This
is cut down from 60Hz, with a slope of -3dB.
8. Input RCA -
This entry is formatted RCA (-10dB). It serves to receive
the incoming signal.
9. Fuse -
In case of failure, replace the original fuse by an equivalent in
type and characteristics.
10. General Power -
Power cord before connecting to the mains, always check that
the mains voltage corresponds to the voltage selected on the back of the unit.
11. Voltage selector -
This switch, protected by a cover, you can use the device
at mains voltage 220Vac or 110Vac. Always check that the mains voltage
corresponds to the voltage selected on the back of the unit.
12. Jack 6.35 TRS and XLR Input -
These connectors are used to receive the
input signal and accept balanced and unbalanced signals.
- XLR: pin1 = Ground; pin2 = Positive signal; pin3 = Negative signal
- Jack 6.35 TRS: (In parallel with the XLR) Tip = Positive signal;
Ring = Negativesignal; Body = Ground.
The input impedance is greater than 40KΩ.
13. Jack 6.35 TRS and XLR Output -
These forms are used to output the
processed signal and accept balanced and unbalanced signals, the pinout is
the same as the input jacks.
14. Output RCA -
This output format is RCA (-10dB). It can be used
simultaneously with the XLR or Jack 6.35.
15. Rec out -
This output format is RCA (-10dB). It can be used simultaneously
with the XLR, Jack 6.35 or RCA. Its signal output is identical to the output RCA.
