This Troubleshooting section specifically concerns the operation
of the EVO Mixer and EVO Microphones.
For problems associated specifically with EVOi.324
Loudspeakers and the integrated EVOi.net please refer to the
Troubleshoot Sections in each User's Guide respectively.
The EVO Mixer Station Doesn't Power Up:
Check that the AC mains supply is present. Check that the
mains voltage selection is correct for your country.
Check that the AC mains power cord is firmly connected.
Check the AC mains fuse.
If none of the above provide a solution then contact your
Dealer.
My condenser microphone is not working:
Check that the 48V phantom power is on.
Make sure the mic is plugged into the Mic input.
Make sure that the mic cable is a balanced 3-wire type.
The Meters don't show any signal:
Check that the input gain has been set correctly.
Make sure that the source is connected to the appropriate input
socket for the level of signal.
Do you have something connected on the Inserts, and is that
external device switched on?
Are the Master faders set at max., are input faders set high
enough and is the channel routed to the output being moni-
tored?
Check that the Mute switch is not engaged on the relevant
channel.
Is the appropriate monitor select switch pressed?
Is there a SOLO or AFL pressed on another channel?
There is no Mix output:
Check that the Mix Master fader is up.
Do you have something connected on the Mix Inserts, and is
that external device switched on?
There is no Monitor output:
Is the monitor control set high enough?
Is the appropriate monitor select switch pressed?
My headphones are distorting:
Check that the Phones level is not set too high.
Are the headphones less than 200 ohm impedance?
How do I prevent my wireless microphones
from cutting out, clicking, and generally being
noisy:
Try to keep a minimum transmitter to receiver distance of 16ft
(5m).
Make sure the transmitter is never more than 164ft (50m) from
the receiver.
Keep the two transmitters at least 40” (1m) apart, and check
before the performance what frequency to set each to for best
operation.
Make sure that the Bodypack transmitter antenna hangs freely,
and doesn't make contact with the user’s skin. The human body
attenuates RF signals.
Always use fresh batteries before a performance!
The Reception on the selected carrier frequency
is disrupted:
Change the carrier frequencies. Make sure these are at least one
step up or down from each other. This is necessary to provide
the minimum frequency spacing required for intermodulation-
free operation.
IMPORTANT: Make sure the Transmitter and the Receiver are
both switched OFF when changing the carrier frequency. The
new, selected carrier frequency is activated when the Transmitter
is switched back ON.
