Safety Instructions
Symbols used
The “CAUTION” symbol indicates a risk of product degradation.
The “WARNING” symbol indicates a risk to the physical integrity of the user
and any other person present. The product may also be damaged.
Attention: To reduce the risk of ! electric shock, do not remove the
user-serviceable piece inside. Contact a qualified service technician for
maintenance of this unit.
Noise Levels: PA systems are capable of delivering sound level (SPL)
harmful to human health. The sound pressure levels are apparently not critical
damage your hearing if the person is exposed over a long period. Do not park
in the immediate vicinity of loudspeakers in operation.
The symbol lightning-shaped in an equilateral triangle is intended to alert
the presence, inside the box, non-insulated parts tensions high enough to
constitute a risk of electric shock.
he exclamation point within an equilateral triangle is intended to alert the
user to the presence of maintenance or operations in the device documentation.
Risk of Electric shock: To prevent the risk of electric shock, do not use
extension cords, making multiple of another connection system without metal
parts in contact are completely out of reach.

This product should not be placed in such a closed suitcase or rack unless ventilation has been provided or the manufacturer’s instructions have been followed.
- Heat: It is advisable to keep the product away from heat sources such as radiators, stoves, the heat reflector or other products (and the amplifier) which produce heat.
- Electric power: This product works only on the voltage indicated on a label on the back of the unit. If you are not sure of the voltage of your electrical installation, consult your dealer or local power company.
- Protection of electric cables: Must ensure that the cables are not likely to be walked on or pinched by items placed upon or against, paying particular attention to cords at plugs and the point where they exit from the appliance. Cleaning: Unplug the unit.
- before cleaning. Do not use accessories not recommended by the manufacturer. Use a damp cloth on the surface of the device. Do not move the device under water.
- Period of non-use: Unplug the power cord from your drive if you do not use it for a long time.
- Penetration of objects or liquids: Never let penetrate any kind of objects into this unit through openings as they may cause fire or electric shock. Never spill any kind of liquid on the product.
- Damage requiring service: Please contact qualified personnel in the following cases.
- When the power cord or plug is damaged.
- If liquid has been spilled or objects have fallen into the apparatus.
- If the product has been in contact with rain or water.
- If the product does not operate normally by following the instructions.
- If the product has taken a shock
- Maintenance/revision: Do not try to revise this product yourself, it may expose you to dangerous voltage. Please contact a qualified staff.
Operating environment
- Temperature and humidity of the operating environment: +5∘~ +35∘.
- Relative humidity below 85% (unobstructed vent).
- Do not install the unit in a poorly ventilated area, or in a place subject to high humidity or direct sunlight (or strong artificial light).
Various tips
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.
General Characteristics
Stereo equalizer 2×15 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.
- Stereo 15-band equalizer, 2/3 octave of 31.5Hz to 16KHz
- Adjustable output level: +12/-12dB
- 20mm faders
- Frequency response: 20Hz~20KHz ±1dB
- Frequency-set: +/-12dB (+/-0.5dB)
Front and Rear Panels
Power button
- This button to turns the unit on or off.
Power indicator
- This LED lights up when the EQ is in working condition.
Key IN/OUT
- This button, once pressed, bypasses the EQ section.
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).
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.
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.
Low Cut
- This button will activate the low-cut integrated equalizer.This is cut down from 60Hz, with a slope of -3dB.
Input RCA
- This entry is formatted RCA (-10dB). It serves to receive the incoming signal.
Fuse
- In case of failure, replace the original fuse by an equivalent in type and characteristics.
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.
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.
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.
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.
Output RCA
- This output format is RCA (-10dB). It can be used simultaneously with the XLR or Jack 6.35.
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.
