Introduction

Connections

Congratulations on purchasing the Gemini UMX-3 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-controlled 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.Make sure that the POWER (1) switch is in the off position. The POWER LED (32) will be off. This unit comes supplied with a 18 volt AC adaptor. Plug the adaptor into the rear panel power jack. Then plug the adaptor into a proper power source.

2.The UMX-3 is supplied with 4 sets of output jacks. The BALANCED MASTER OUTPUT (4) jacks are used to connect to your main amplifier using standard cables with 1/4” connectors. 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). The balanced line uses a tip-ring-sleeve connection. Tip = hot or positive (+), ring = cold or negative (-), and sleeve = shield/ground. The MASTER OUTPUT (5) jacks are unbalanced and used to connect to your main amplifier. The REC OUTPUT (7) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix. The ZONE OUTPUT (6) jacks allow you to hook up an additional amplifier.

3.The MIC (3) input (found on the rear panel) OR the MIC (35) input (found on the front panel) accepts a 1/4" connector and balanced and unbalanced microphones.

4.On the rear panel are 3 stereo PHONO/LINE (9, 12, 13) inputs and 1 stereo LINE (8) input. The PHONO/LINE SWITCH (10) enables you to set the (9) input to Phono or Line. The PHONO/LINE SWITCH (11) enables you to set the (12) input to Phono or Line. The PHONO/LINE SWITCH (14) enables you to set the (13) input to Phono or Line. The phono inputs will accept only turntables with a magnetic cartridge. GROUND SCREWS (2) 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.

5.Headphones can be plugged into the front panel mounted PHONES (36)jack.

HeightAdjustment

When using a UMX mixer with professional turntables, such as the Gemini PT 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 replacethe 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.

Operation

1.POWER ON: Once you have made all the equipment connections to your mixer, press the POWER (1) switch. The power will turn on and the POWER LED (32) will light.

2.CHANNEL 1: The GAIN (21) control allows you to individually adjust the gain of the channel. Switch # (24) allows you to select the LINE 1/ PHONO 1 (13) or the LINE 2/PHONO 2 (12) input. The CHANNEL SLIDE(29) controls the input level of this channel.

3.CHANNEL 2: The GAIN (23) control allows you to individually adjust the gain of the channel. Switch # (26) allows you to select the LINE 3/ PHONO 3 (9) or the LINE 4 (8) input. The CHANNEL SLIDE (30) controls the input level of this channel.

4.INPUT ASSIGN SWITCHES: You can adjust the position of the INPUT ASSIGN (24, 26) switches to move left to right, up and down OR at a 45 degree angle. Make these adjustments with the power OFF.

1)Remove the channel slide, crossfader knobs and the 4 screws from the sides of the lower face plate. Then remove the lower faceplate.

2)Remove the 2 screws in the corners of the assign switch plate. Rotate the switch plate to the desired position, replace the screws and tighten down.

3)To position the switch at a 45 degree angle, you need to reposition the switch on the assign switch plate. First, remove the 2 screws in the corners of the assign switch plate. Then, lift the switch plate up and remove the 2 smaller screws next to the switch. Rotate the switch plate to the right until the 45 degree holes align with the switch holes, replace the screws and tighten down. Replace the switch plate and tighten down.
