(3)INTRODUCTION:Congratulations on purchasing a GEMINI model EQ-3000 equalizer. Thisstate of the art equalizer includes the latest features and is backed by athree year warranty. Prior to use, we suggest that you carefully read allthe instructions.FEATURES:• Balanced/Unbalanced Inputs & Outputs• In/Out Pass Switch• Low Cut Switch• Level DisplayCAUTIONS:1. All operating instructions should be read before using this equipment.2. To reduce the risk of electrical shock, do not open the unit. There areNO USER REPLACEABLE PARTS INSIDE. Please refer servicing to aqualified service technician.In the U.S.A., if you have any problems with this unit, call 1-732-738-9003 forcustomer service. Do not return equipment to your dealer.3. Do not expose this unit to direct sunlight or to a heat source such as aradiator or stove.4. This unit should be cleaned only with a damp cloth. Avoid solvents orother cleaning detergents.5. When moving this equipment, it should be placed in its original cartonand packaging. This will reduce the risk of damage during transit.6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANYCONTROLS OR SWITCHES.CONNECTION:1. Make sure that the POWER (1) switch is in the OFF position (thePOWER LED will be off). All connections must be made with allequipment OFF.2. Before plugging in the power cord, make sure the VOLTAGESELECTOR (8) switch is set to the correct voltage. Plug the unit into aproper power source.3. Connect the input signal to your EQ-3000 by using either the RCA or1/4" INPUT JACKS (9).4. Connect the cables for the output signal of the EQ-3000 to either theRCA, XLR or 1/4" OUTPUT JACKS (10).NOTE: USE THE 1/4" OR XLR JACKS FOR BALANCED SIGNALS AND THE RCA JACKS FORUNBALANCED SIGNALS.5. If you desire to record your mix, connect the REC OUTPUT (11) jacks tothe input of your recorder.USING THE GROUND LIFT SWITCH:Depending on your system configuration, sometimes applying theground will create a quieter signal path. Sometimes lifting the groundcan eliminate ground loops and hum to create a quieter signal path.1. With the equalizer on, listen to the system in idle mode (no signalpresent) with the ground applied (the GROUND LIFT SWITCH (12) inthe left position).2. Then turn the power off before moving the GROUND LIFTSWITCH (12). Lift the ground by moving the GROUND LIFT SWITCH tothe right, turn the power back on and listen to determine which positionwill provide a signal free of background noise and hum. Keep theGROUND LIFT SWITCH in the ground position if the noise level remainsthe same in either position.CAUTION: DO NOT TERMINATE THE AC GROUND ON THE EQUALIZER IN ANY WAY.TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.OPERATION:1. POWER ON: Once you have made all the equipment connections toyour equalizer, press the POWER SWITCH (1). The power will turnon and the POWER LED (2) will glow RED.2. IN/OUT PASSING SWITCH: When the IN/OUT PASS SWITCH (3) is inthe “IN” position, the EQ-3000 will activate. If the switch is in the “OUT”position, the signal will pass through the EQ-3000 without beingequalized.3. GRAPHIC EQUALIZER: The EQUALIZER SLIDE CONTROLS (4) areprovided to improve the frequency response of your system and tocompensate for room and environmental conditions. There are fifteenbands per channel, each allowing +/- 12 dB adjustments. The bandsrange from 31.5 Hz to 16 kHz.4. LEVEL CONTROL: Use the LEVEL CONTROLS (5) to obtain a properoutput signal. Each LEVEL CONTROL (5) has a bank of four LEVELDISPLAY LEDs (6). These indicate the output level in four steps from -10 dB to +17 dB. If the +17 dB LED indicator is on, there is too muchoutput power and distortion will result. Lower the LEVEL CONTROL (5)until this LED goes off.5. LOW CUT SWITCH: The LOW CUT SWITCHES (7) are designed toattenuate the muddy and unwanted low frequency sound created byyour source equipment (especially turntable rumble).SPECIFICATIONS:Channels........................................................................................2 Channels15 Bands/Channel: 31.5, 40, 63, 100, 160, 250, 400, 500, 630, 800, 1k, 2k, 4k,8k, 16 kHzInput Impedance................................................................................1.2 kOhmOutput Impedance..............................................................................20 kOhmMax Output Level.................................................................................11 voltsLevel Control.....................................................................................+/- 12 dBS/N Ratio.................................................................................................90 dBDistortion...............................................................................................0.03 %Power.........................................................................................120/230 voltsPower Consumption..........................................................................15 wattsDimensions............................19" W x 1.75" H x 9.75” D (483 x 45 x 248 mm)Weight........................................................................................8 lbs.
