JBL EVOi.net User Manual page 28

EVOi.net is used as the interface for the set up and
operation of EVO Loudspeakers. The following section
may help in resolving some problems that may occur.
Check the indicator. If it is illuminated, then
disengage the Switch on the rear panel (#14
page 6).
The input signal level to EVOi.net is too high. Lower the
input level to EVOi.net. This is likely to occur if the EVO
Loudspeakers are not powered up and there is no audible
way of hearing a 'clipped' signal. If this is the case,
determine the cause of the EVOi.324's not producing
sound.
If only the is flashing occasionally, it indicates
that the electronics in the EVOi.324 connected to that
has detected a signal level that engages the built-
in limiting circuitry. Lowering the signal level will resolve
this .
Error codes are flashed as a sequence of two digits. After
the first digit, there is a short gap and after the second digit,
there is a longer (1 second) gap. Errors are prioritized, so if
a speaker has more than one error condition, the most
important error will be shown until it is cleared, at which
point the second error will be shown. Pressing any button
when an error code is being displayed will clear the highest
priority error.
An error/status code is being reported when the green
( ) LEDs begin flashing. Take note of the green
LED's flashing code and its most likely cause using the
chart on page 27.
After the error code is noted, the less serious errors may be
cleared by pressing any of the rectangular buttons on the
front panel of EVOi.net.
Check the configuration of

With disengaged, signal from

Has delay setup been engaged? (Is the
on above button)?
In a delay setup, typically the rear speakers are lowered to a
level (6-10dB) and delayed (approximately 15ms behind
any signal arriving from the main speakers) that allows
them to effectively disappear, forcing the localization of the
image to the front pair. Use the test function (if enabled) to
determine presence of all 4 speakers.
Has setup routine been used?
Have all filters been used? While the anti-feedback circuit
has been carefully designed to minimize the impact of
feedback, there will still be a point beyond which the
system is so feedback prone that further increase in gain
will result in additional feedback. A point is eventually
reached where so many feedback frequencies must be
removed, that it either requires an enormous number of
filters, or it requires lowering gain to keep the system
usable. The gain to the microphone should be lowered to
prevent the creation of feedback.
