in color. The LEDs that represent “0dB” are YELLOW in color and the LEDs that
rep3dB or greater are RED in color. Thus you can just give a quick
glance to the meters and determine if your audio levels are too high by noting the
color present.
Power Switch
On the lower right hand corner of the front panel is the main power switch. This
switch controls all of the power used to operate the ProMix 6 audio mixer. This
switch is labeled “PWR” and is a three position switch. In the left most setting,
the switch is labeled “EXT” and this refers to external power. The mixer will
operate when the switch is set to EXT and it is connected to an external power
source such as an AC wall supply or external battery. In the center position, the
mixer is turned off. In the right most position marked “BATT” the mixer will
operate from its internal batteries. Whenever the mixer is turned on, the first
LED in each row of meter LEDs will light up Blue. This indicates proper
operating voltage is present in the internal batteries or the external power source.
When the batteries get low, these two blue LEDs will begin blinking. This
blinking condition indicates that the batteries useful life is nearly over and you
should stop and change your batteries soon. Actual remaining battery life is
dependent upon use of the mixer, number of powered condenser microphones
being used etc. You can typically expect 15 to 20 minutes of remaining run time
once the blue LEDs begin blinking.
Slate Microphone
The PSC ProMix 6 audio mixer is equipped with an internal slate microphone.
This slate microphone is used to provide on tape, voice slating of scène and take
notes, editing notes and other voice notes for future use. To operate the slate
microphone, simply press the “Slate Mic” button. This button is momentary and
thus the slate microphone will only activate for as long as you press the button.
There is also a slate microphone volume level trim pot located just to the left of
the slate mic button.
Reference Oscillator
The ProMix 6 audio mixer is equipped with a reference tone oscillator that is
used to provide a reference tone level for production editing. This tone oscillator
puts out a 440Hz tone at 0dB on the meters. At the beginning of each tape or at
the first use of any other audio storage format, you should record a 15 to 20
second burst of reference tone. This tone will be used later in post production to
set proper audio levels for subsequent transfers and is used to keep audio levels
consistent among multiple cameras.
