Troubleshooting
No power LED on control panel
Ensure mains outlet voltage is correct for the unit
Check power is switched on at the rear panel
Check IEC fuse
–
if blowing fuses, refer to qualified service personnel
Power LED is on but no other LEDs and
no output
Check input signals and condition of connection leads
Check GAIN is not too low on channel input
Check Gain/Level controls and EQ controls are not turned fully down
When using condenser microphones, check that +48V phantom is on.
Check that PFL/AFL buttons are all switched out
Check that all Graphic EQ sliders are not fully down
For MPR digital audio inputs, check signal routing
Power light and VU LEDs lighting but no
speaker output
Check output connections to speakers
Check that speakers are in good working order
Check MASTER faders are not fully down
No playback from USB or SD media
Check that files are standard compressed audio format
Check routing option for MPR section, switch to main L/R
Check MPR level and/or ST2 level controls
VU LEDs do not show MAIN output levels
Check that PFL/AFL buttons are all switched out
Output is very loud or distorted
Check level of input signal is not too high
Reduce Gain/Level controls and EQ settings
Ensure Hi-Z line level input(s) not connected via XLR
Check AUX and DSP level controls and reduce if necessary
Output is working but at very low level
Check input audio source level is not too low
Ensure low impedance line or mic signal is not connected via jack
Increase Gain/Level controls and EQ settings if turned down
