Introduction
Congratulations on purchasing a Gemini model EQ-30 equalizer. This
state of the art equalizer includes the latest features and is backed by a
three year warranty. Prior to use, we suggest that you carefully read all
the instructions.
to the right, turn the power back on and listen to determine which
position will provide a signal devoid of background noise and hum.
Keep the GROUND LIFT SWITCH in the ground position if the noise
level remains the 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.
Features
• Balanced/Unbalanced Inputs & Outputs
• In/Out Pass Switch
• Low Cut Switch
• Level Display
Cautions
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 are
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
In the U.S.A., if you have any problems with this unit, call
1-732-738-9003 for customer service. Do not retur n equipment
to your dealer.
3. Do not expose this unit to direct sunlight or to a heat source such as
a radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.
5. When moving this equipment, it should be placed in its original carton
and 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 ANY
CONTROLS OR SWITCHES.
Connection
1. Make sure that the POWER (1) switch is in the off position (the
POWER LED will be off). All connections must be made with all
equipment OFF .
2. Before plugging in the power cord, make sure the VOLTAGE
SELECTOR (8) switch is set to the correct voltage. Plug the unit into
a proper power source.
3. Connect the input signal to your EQ-30 by using either the RCA or
1/4" INPUT JACKS (9).
4. Connect the cables for the output signal of the EQ-30 to either the
RCA or 1/4" OUTPUT JACKS (10).
NOTE: Use the 1/4" jacks for balanced signals and the
RCA jacks for unbalanced signals.
5. If you desire to record your mix, connect the REC OUTPUT (11) jacks
to the input of your recorder.
Operation
1. POWER ON: once you have made all the equipment connections to
your equalizer, press the POWER SWITCH (1). The power will turn
on and the POWER LED (2) will glow RED.
2. IN/OUT PASSING SWITCH: when the IN/OUT P ASS SWITCH (3) is in
the “IN” position, the EQ-30 will activate. If the switch is in the “OUT”
position, the signal will pass through the EQ-30 without being
equalized.
3. GRAPHIC EQUALIZER: the EQUALIZER SLIDE CONTROLS (4) are
provided to improve the frequency response of your system and to
compensate for room and environmental conditions. There are fifteen
bands per channel, each allowing +/- 12 dB adjustments. The bands
range from 31.5 Hz to 16 kHz.
4. LEVEL CONTROL: use the LEVEL CONTROLS (5) to obtain a proper
output signal. Each LEVEL CONTROL (5) has a bank of four LEVEL
DISPLAY 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 much
output 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 to
attenuate the muddy and unwanted low frequency sound created by
your source equipment (especially turntable rumble).

Using the Ground Lift Switch
Depending on your system configuration, sometimes applying the ground
will create a quieter signal path. Sometimes lifting the ground can
eliminate ground loops and hum to create a quieter signal path.
1. With the equalizer on, listen to the system in idle mode (no signal
present) with the ground applied (the GROUND LIFT SWITCH (12) in
the left position).
2. Then turn the power off before moving the GROUND LIFT
SWITCH (12). Lift the ground by moving the GROUND LIFT SWITCH
