MIXPAD 4 Main Section
3: Left/Right Peak LEDs (red) - These warning lights indicate an
overload situation. They light whenever the main left or right output
signal is 5 dB short of clipping. To stop them from lighting (and to
eliminate the accompanying sonic distortion), turn down the Main Level
control (see #8 below). See the “Setting the Correct Gain Structure”
section on page 23 in this manual for more information.
4: Power LED (green) - This LED indicates battery strength. It flashes
briefly whenever the MIXPAD 4 is powered on and lights steadily when
the batteries are low and need replacing.
5: Power on-off switch - As you may have guessed, this is what you
use to turn the MIXPAD 4 on and off. To avoid potential damage to your
speakers, turn the unit on
before
you turn on any connected power
amps—and turn it off
after
the power amps are turned off.
6: Stereo Auxiliary Return Level (tan) - This knob determines the input
level of signal arriving via the MIXPAD 4’s stereo Auxiliary return. The
Aux return is at unity gain (no boost or attenuation) when set to the “0”
(2 o’clock) position; the signal is boosted when the knob is turned to the
right of “0” and attenuated when turned to the left of “0.” For information
on how to properly set this, see the sections in this manual entitled
“Setting the Correct Gain Structure” and “Using Aux Sends and Returns”
(pages 23 and 32). Note that signal applied to the Aux return is
automatically routed to the Main L/R output.
7: Headphone jack - Connect any standard stereo headphones to this
jack (via a standard 1/4" TRS plug) for private monitoring of the main
stereo output (pre-Main Level). The built-in MIXPAD 4 headphone
preamp delivers 38 mw at 600 ohms.
8: Main Level (white) - This knob determines the final output signal
level—you can think of this as being the “master fader.” Signals from all
channels and the Aux return, as well as the Tape/CD input are routed
here just before leaving the MIXPAD 4 via its left and right main output
jacks. The “0” position of the knob indicates unity gain (no level
attenuation or boost). Moving the knob counterclockwise from the “0”
position causes the signal to be attenuated (at the fully counterclockwise
position, it is attenuated infinitely—in other words, there is no sound).
Moving it clockwise from the “0” position causes the signal to be boosted
by as much as 10 dB. Note that the Main Level control has no effect on
the headphone level. For more information, see the “Setting The Correct
Gain Structure” section on page 23 of this manual.
