with

professional

turntables,

such

the

Gemini

Series,

you

can

make

the

mixer

level

with

the

turntable

removing

the

mixer’s

feet.

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

Connections

. 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.

. The UMX-7 is supplied with 4 sets of output jacks. The BALANCED

BALANCED

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 OUTPUTS

BALANCED 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.

. 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 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).
