JBL EVOi.net manual Troubleshooting

T R O U B L E S H O O T I N G

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.

1.The front panel is inoperative and does not respond to button pressing:

Check the LOCKED indicator. If it is illuminated, then disengage the LOCKOUT Switch on the rear panel (#14 page 6).

2.The CLIP LED’s on the EVOi.net’s INPUT (#1 page 4) are illuminating:

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.

3.The SPEAKER STATUS indicators are flashing:

If only the RED LED is flashing occasionally, it indicates that the electronics in the EVOi.324 connected to that OUTPUT has detected a signal level that engages the built- in limiting circuitry. Lowering the signal level will resolve this WARNING.

SPEAKER STATUS Error codes

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 (OKAY) 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.

4.I’m sending signal, but one channel is not working?

Check the configuration of MONO SUM (#15, 16 on page 6). MONO SUM engaged will allow signal from INPUT A to flow to OUTPUTS 1 & 2 and 3 & 4 simultaneously.

With MONO SUM disengaged, signal from INPUT A will flow to OUTPUTS 1 & 3 and signal from INPUT B will flow to OUTPUTS 2 & 4.

5.My rear speakers aren’t working.

Has delay setup been engaged? (Is the DELAY SET LED on above DELAY SETUP 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.

6.Anti Feedback is on, yet my system is still feeding back.

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.
