“0”. Once noted, adjust your camera’s meters to read “0” as well. Once your

camera’s meters are adjusted to match the meters of the DV ProMix 3’s meters,

you can turn off the reference tone oscillator. This procedure generally requires

only about 20 to 30 seconds to complete and will help you produce higher quality

audio in the field. If you are using multiple cameras or you must edit together

tape shot over multiple days, these segments of tone recorded at the beginning

of each tape or at the beginning of each days shoot will come in handy. When

you edit the tapes together, you must simply adjust the audio level on your

editing software to match the “0” Tones. Once this is done, all of your audio will

be of consistent level and thus much better comprehended.

POWERING:

A. INTERNAL POWER, ALKALINE BATTERIES

Two “9 Volt” alkaline batteries are normally used to power the DV Promix 3

Mixer. These batteries are housed in a convenient battery compartment located

on the rear panel of the mixer. When using two alkaline batteries, you can

expect 4 to 6 hours of operation under normal circumstances. In an emergency,

the mixer will operate from one battery, but battery life will be substantially

reduced. Please note there is a polarity to the batteries and they must be

installed correctly. You will note that there are polarity markings inside the

battery drawers. Before installing the batteries into these holders or “drawers”

take a look into the holder itself and note the + and – symbols.

Note: Never store your DV Promix 3 Mixer for extended periods of time with

alkaline batteries installed in the mixer. There is a possibility that the

batteries may leak causing corrosion of the mixer. Battery leakage and the

resulting corrosion damage is not covered under the DV Promix 3 Mixer

warranty.

B. EXTERNAL POWER

The PSC DV Promix 3 Mixer can also be externally powered from any source of

DC power from 7 to 16 Vdc. The mixer consumes a minimum 70 mA over this

voltage range. The external power connector is located on the rear panel of the

mixer. Pin outs of this connector are as follows:

Center Pin (+) Positive

Outside Ring (-) Negative
