Gemini UMX-SE manual Introduction, Features, Height Adjustment, Connections, Operation

INTRODUCTION:

Congratulations on purchasing the UMX DIVISION UMX-SE VCA mixer. This state of the art mixer is backed by a three year warranty, excluding CROSSFADER and channel slides. Prior to use, we suggest that you carefully read all the instructions. With VCA technology, audio is processed in a voltage-control LED amplifier (VCA) removing it from the CROSSFADER and channel slides giving them extended life and reducing travel noise. The CROSSFADER and channel slides regulate the DC voltage that controls the VCA circuit. Additional advantages of VCA technology include the ability to provide precise curve adjustments for the CROSSFADER and channel slides without sacrificing audio quality. For additional information, refer to the diagrams on PAGE 3 for CROSSFADER adjustment and channel slide curve.

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 RETURN 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.

HEIGHT ADJUSTMENT:

When using a UMX mixer with professional turntables, such as the UMX DIVISIONPT Series, you can make the mixer

level with the turntable by removing the mixer’s feet.

1.Place a small screw driver under the foot’s center anchor.

2.Gently pry the center anchor up and the foot will come OFF.

To replace the foot:

1.Place the foot on the mixer without the center anchor.

2.Replace the center anchor and push down on it to anchor the foot to the mixer.

CONNECTIONS:

1.Before plugging in the power cord, make sure that the VOLTAGE SELECTOR (1) switch is set to the correct voltage.

2.Make sure that the POWER (8) switch is in the OFF position. The POWER LED (20) will be OFF.

3.The UMX-SEis supplied with 4 sets of output jacks. The BALANCED MASTER OUTPUT (9) jacks are used to connect to your main amplifier using standard XLR cables. We recommend using the balanced amp outputs if the cables to your amp are 10 feet or more. BALANCED MASTER OUTPUTS have three separate conductors, two of which are signal (positive and negative) and one shield (ground). Pin 1 is ground (shield). Pin 2 is signal hot (positive). Pin 3 is signal cold (negative). The MASTER OUTPUT (11) jacks are unbalanced and used to connect to your main amplifier. The REC OUTPUT (10) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix. The ZONE OUTPUT (12) jacks allow you to hook up an additional amplifier.

4.The MIC (7) input (found on the rear panel) accepts a 1/4" connector and balanced and unbalanced microphones.

5.On the rear panel are 3 stereo PHONO/LINE (14, 16, 17) inputs and 2 stereo LINE (13, 15) inputs. The PHONO/LINE SWITCH (3) enables you to set the (14) input to Phono or Line. The PHONO/LINE SWITCH (4) enables you to set the (16) input to Phono or Line. The PHONO/LINE SWITCH (6) enables you to set the (17) input to Phono or Line. The phono inputs will accept only turntables with a magnetic cartridge. GROUND SCREWS (5) for you to ground your turntables are located on the rear panel. The stereo line inputs will accept any line level input such as a CD player, a cassette player, etc.

6.Headphones can be plugged into the front panel mounted PHONES (45) jack.

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 mixer on, listen to the system in idle mode (no signal present) with the ground applied (the GROUND LIFT SWITCH (2) in the left position).

2.Then turn the power OFF before moving the GROUND LIFT SWITCH (2). Lift the ground by moving the GROUND LIFT SWITCH 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 POWER MIXER IN ANY WAY. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.

OPERATION:

1.POWER ON: Once you have made all the equipment connections to your mixer, press the POWER (8) switch. The power will turn on and the POWER LED (20) will light.

2.CHANNEL 1: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN

(27)controls allow you to fully adjust the selected source. Switch # (29) allows you to select the PHONO 1/LINE 1 (17) or the MIC (7) input. The CHANNEL SLIDE (33) controls the input level of this channel.

3.CHANNEL 2: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN

(27)controls allow you to fully adjust the selected source. Switch # (30) allows you to select the PHONO 2/LINE 2 (16) or the LINE 3 (15) input. The CHANNEL SLIDE (34) controls the input level of this channel.

4.CHANNEL 3: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN

(27)controls allow you to fully adjust the selected source. Switch # (31) allows you to select the PHONO 3/LINE 4 (14) or the LINE 5 (13) input. The CHANNEL SLIDE (35) controls the input level of this channel.

5.TONAL CONTROLS: There is Low, Mid and High equalization for each channel with an extremely wide range of adjustment.

SUGGESTION: YOU CAN USE THE CUT FEATURES ON EACH CHANNEL TO REMOVE LOW, MID AND/OR HIGH TO CREATE SPECIAL EFFECTS.

6.INPUT ASSIGN SWITCHES: You can adjust the position of the INPUT ASSIGN (29, 30, 31) switches to move left to right, up and down OR at a 45 degree angle. Make these adjustments with the power OFF.
