IntroductionIntroduction

Introduction

Congratulations on purchasing the Gemini UMX-7 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.

Height AdjustmentHeight Adjustment

Height Adjustment

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 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.

ConnectionsConnections

Connections

1. Make sure that the

POWER (1)POWER (1)

POWER (1) switch is in the off position. 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-7 is supplied with 4 sets of output jacks. The

BALANCED BALANCED

BALANCED

MASTER OUTPUT (4)MASTER OUTPUT (4)

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 25 feet or

more.

BALANCED MASTER OUTPUTSBALANCED MASTER OUTPUTS

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) MASTER OUTPUT (5)

MASTER OUTPUT (5) jacks are unbalanced and

used to connect to your main amplifier. The

REC OUTPUT (7) REC OUTPUT (7)

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) ZONE OUTPUT (6)

ZONE OUTPUT (6) jacks allow

you to hook up an additional amplifier.

3. For your convenience, there are 2 mic inputs (located on the front panel

and the rear panel), however, only one mic input can be used at a time.

The

MIC (3)MIC (3)

MIC (3) input (found on the rear panel)

OR OR

OR the

MIC (42)MIC (42)

MIC (42) input

(found on the front panel) accepts a 1/4" connector and balanced and

unbalanced microphones. The

MIC LOOP (14)MIC LOOP (14)

MIC LOOP (14) jack acts as an output

and input for connection to an outboard signal enhancer (such as a key

controller, echo/reverb machine, etc...) using a standard balanced cable

with a 1/4” tip/ring/sleeve connector (tip = in, ring = out, and sleeve

= shield/ground).

4. On the rear panel are 3 stereo

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
