1. Stereo Fader
This stereo 100mm slide fader adjusts the level of the left and right channels and has a range of ∞dB to
10dB. The operation of the slide fader simultaneously adjusts the level to the left and right XLR line
outputs. The “0” mark is the “unity gain” setting for the
fader channel.
Fader Input to Fader Output Gain
With a ba4dBu signal present at the XLR line
input, the fader set to the “0” mark, and the Gain Select
jumper in the default (0dB) position, the corresponding
balanced XLR line output will be +4dBu.
With the gain jumper in the 6db or 10dB position and the
slide fader set at the “10” mark, this will give the channel
a total of 16dB or 20dB of gain respectively.
2. Power LED
This LED will illuminate green when power is applied to
the Fader 3.
3. Pre/Post Select
This switch selects the source of the monitor and
headphone level controls. In the “Up” position the
monitor and headphone signal source is Pre (before) the
slide fader. In the “Down” position the monitor and
headphone signal source is Post (after) the slide fader. A
yellow LED will illuminate when this switch is in the
Post position.
4. Monitor Level Control
This stereo potentiometer adjusts the overall level to the
stereo Monitor Output Jacks on the rear panel and
typically controls the volume to a stereo power amplifier
or powered speakers.
The source of the headphone level
can be either “Pre” or “Post” the slide fader and is
selected with the Pre/Post Select Switch.
5. Headphone Level Control
This stereo potentiometer controls the volume of the stereo
headphone jack that is located on the front panel. The source of
the headphone level can be either “Pre” or “Post” the slide fader
and is selected with the Pre/Post Select Switch.
6. Headphone Jack
This standard 1/4” TRS headphone phone jack will accommodate most popular stereo headphones and is
adjusted with the Headphone Level Control. The tip of the 1/4” jack is the left headphone signal, and the
ring of the jack is the right headphone signal.
