Safety Instruction

1. Read these instructions.2. Keep these instructions.3. Heed all warnings.4. Follow all instructions.5. Do not use this apparatus near water.6. Clean only with dry cloth.7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including

amplifiers) that produce heat.9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one

wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the thirdprong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician forreplacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and thepoint where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.

When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in

any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into theapparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Information for Users on Collection and Disposal of Old Equipment and used BatteriesThese symbols on the products, packaging, and/or accompanying documents mean that used electricaland electronic products and batteries should not be mixed with general household waste. For propertreatment, recovery and recycling of old products and used batteries, please take them toapplicable collection points, in accordance with your national legislation.By disposing of these products and batteries correctly, you will help to save valuable resources andprevent any potential negative effects on human health and the environment which could otherwise arisefrom inappropriate waste handling.For more information about collection and recycling of old products and batteries, please contact yourlocal municipality, your waste diposal service or the point of sale where you purchased the items.

Information on Disposal in other Countries outside the European UnionThese symbols are only valid in the European Union. If you wish to discard these items, please contactyour local authorities or dealer and ask for the correct method of diposal.

Note for the battery symbol (bottom two symbol examples):The sign Pb below the symbol for batteries indicates that this batteries contains lead.

Operation

1. Check the power source first, and plug in.

2. Place all switches on OFF position and adjust frequency control volume on 0dB.

3. Turn on power switch and check the operation statue.

4. Adjust to proper tone by controlling fader per frequency.

5. If EQ function is not needed, press bypass switch to ON position.

6. If there is rumble noise, remove it with HPF.

1. EQ BOOST AND CUT CONTRLThis unit can adjust 31-band frequency spectrum range of ±12dB / ±6dB.

Also it can adjust 1/3 octave center frequency of band frequency spectrum 20Hz, 25Hz, 31.5Hz, 40Hz, 50Hz, 63Hz,

80Hz, 100Hz, 125Hz, 160Hz, 200Hz, 250Hz, 315Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1kHz, 1.25kHz, 1.6kHz, 2kHz,

2.5kHz, 3.15kHz, 4kHz, 5kHz, 6.3kHz, 8kHz, 10kHz, 12.5kHz, 16kHz, 20kHz.

2. INPUT GAIN CONTROLThe position of input gain fader determines the overall signal to the circuitry.

When input gain control fader is placed on “0”position, it offers widest dynamic range.

It indicates incoming signal level by using input gain control fader. If incoming signal level is not enough, place input

gain control fader on the highest level (but, be were that it may be worse for S/N ratio).

3. RANGE SWITCHThe position of this switch determines if the fader controls operate over a ±6dB or ±12dB range in the boost cut

mode. In the cut only mode the position of this switch changes the adjustments from -12dB to -24dB.

In most cases the ±6dB (-12dB in cut only) range is sufficient.

4. CUT-ONLY SWITCHWhen CUT-ONLY switch is pressed, it has adjustable range of -12dB or -24dB depends on range switch and inner

LED is illuminated.

CUT-ONLY switch can be used to restrain feedback or ring out of the room.

5. PEAK WARNING INDICATORThis LED illuminates red whenever the corresponding input signal is with in 6dB of clipping.

6. HPF SWITCHBy using high pass filter, it can remove rumbles such as hand noise of microphone easily.

The position of this switch determines if the 80Hz high pass filter is applied to the signal. The switch will illuminate

when the high pass filter is engaged.

7. BYPASS SWITCHThe position of this switch determines whether the unit operates normally or allows the signal to bypass all

equalization setting and pass through unaffected. The switch will illuminate when it is in the bypass mode.

8. POWER SWITCHIf this switch is pressed, the power is supplied and the unit starts operating while inner LED is illuminated.

When the power is off, incoming signal is hard-bypassed to output signal.
