12 Setup & Operation
Basic instructions are described below. For more information about mixer operation, refer to
the Soundcraft EFX EPM User Guide.
 Ensure all source equipment is turned on and
operational (refer to appropriate pages).
 For each input channel (source) in use, verify:
- INSERT jack has nothing plugged into it
- GAIN knob is set to an appropriate level
- PAN knob is set to the center position
- MUTE button is not depressed
 Ensure the mixer is always outputting
PHANTOM POWER (required for the
Announcer’s Interface muting circuit).
 Depress the PFL button to listen to each input
channel without interrupting the main mix.
With an input source playing or while
speaking into the microphone, adjust the gain
knob and channel fader until the output meter
shows 0 dB (Figure 21). Release the PFL
button, and repeat this step for all other
channels in use.
Note: The PEAK LED indicates that the signal
is close to distorting (clipping).
 Slowly bring up the channel and master
volume faders until the output meter displays
0 dB or adequate volume is achieved. Red
LEDs indicate clipping. Also ensure the 2
TRACK MONITOR button is not depressed.
Remember: Bad input = bad output. No adjustment
on the mixer can make a poor source sound better.
For best results, be sure to use high-quality audio files
from your MP3 player or laptop, and set the device to
near full volume.
