USER MANUAL MEQ5.2 APART

• Read all documentation before operating your equipment. Retain all documentation for future reference.
• Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit, use only the original factory packing.
• Do not spill water or other liquids into or on the unit.
• Make sure power outlets conform to the power requirements listed on the back of the unit.
• Do not use the unit if the electrical power cord is frayed or broken.
  • Always operate the unit with the AC ground wire connected to the electrical system ground.
• Have gain controls on amplifiers turned down during power-up to prevent speaker damage if there are high signal levels at the inputs.
• Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off.
• Power down & disconnect units from mains voltage before making connections.
• Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
• Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may distort the normal flow of air around the unit. If the unit is used in an extremely dusty or smoky environment, the unit should be periodically "blown free" of dust.
• Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages.
• Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
• Do not run the output of any amplifier back into another input.
• Do not ground the red output terminal, never connect a red output terminal to another red output terminal.
• In case of mal-function this device should be serviced by qualified service personnel only.

STEREO EQUALIZER

1. Power switch

To turn the unit ON or OFF, press the upper or lower part of this button. The LED above the switch will light to indicate that the unit is ON.

1. Filter level controls

Each one of these linear potentiometers will boost or attenuate (+/-12dB) the selected frequency at a preset bandwidth. When all knobs are in the centre position, the output of the equalizer has a flat response.

1. Volume

This control sets the signal level of the equalizer.

Separate controls for CH1 and CH2

1. Low CUT Hz

You can change the frequency of the low cut filter.

This Low Cut filter can be used to remove low frequencies from the signal

You can use this function to protect small speakers like: satellite speakers.horns.
