Setup and Operation
11
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
the following adjustments ( Figure 19 ):
• 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
• 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 20 ).
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.
Whenever red LEDs are illuminated on the mixer, this is generally a sign that input settings
need to be lowered. For example, if red LEDs are lit in the output meter or PEAK LEDs are
lit, the channel gain and/or fader needs to be lowered. If lowering the fader does not
stop the PEAK LED from illuminating, the gain must be lowered. PROLONGED OVERLOAD
SIGNALS WILL DAMAGE THE AUDIO SYSTEM!
Note: Ensure the mixer is outputting PHANTOM
POWER ( Figure 21 ) when balanced
condenser microphones are plugged into
the mixer inputs.
