Troubleshooting, AC Power, EVOi.324 doesn’t power up

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

The EVOi.324 loudspeaker system has been precision engineered for optimum performance with a minimum of maintenance and outside intervention.

AC Power

The EVOi.324 speaker contains a high-powered amplifier system. Due to the remote locations likely for install, there is no power switch. Application of the AC Mains power will result in the EVOi.324 starting up and initializing (boot process takes about 20 seconds). There is a slight power draw even when EVOi.324 is not passing audio (approxi- mately equivalent to a 100W light bulb (see AC Power requirements page 21). It may be desirable to place a switch on its circuit. This switch should be appropriately rated and installed by a competent electrician in full compliance with all applicable national and local electrical codes.

1. EVOi.324 doesn’t power up:

i.Is it plugged in?

ii.Is the AC Mains circuit adequate for system and energized?

Due to the highly efficient nature of the electronics, there will be a direct correlation between signal level and current draw. While it may be possible to start multiple systems on one AC circuit, continued high level operation may result in occasional brown-outs (see AC Power Requirements on page 21).

2. The Power LED is Flashing:

i.The AC Main voltage is inadequate or out of the rated range (see AC Power requirements page 21).

ii.The AC Mains is not appropriate for the model (i.e. 120V model for 120V service). Check the voltage stated on the rear input label and return to the Dealer if incorrect.

iii.The fuse may have blown. CAUTION: to reduce the risk of fire, replace the fuse with the same type and rating.

iv.If none of the above then immediately contact your Dealer.

3.EVOi.324 powers up, the LED on rear panel lights up, but doesn’t pass audio:

i.Less than 20 seconds have passed. Wait for a couple of moments as EVOi.324 Boots-up.

ii.Check that there is audio signal present:

-Is there a signal cable connected? If so, check that it is not defective.

-Is there signal coming out of the mixer?

-Is EVOi.net attached? (See EVOi.net manual.)

iii.If none of the above then immediately contact your Dealer.

4.The system doesn’t get any louder no matter how much the input signal is turned up:

i.Is it really loud already? Built-in limiters are specially calibrated to prevent damaging levels to the individual speakers in EVOi.324. These limiters are designed to be as transparent as possible while still providing necessary protection functionality. It doesn’t get any louder because it is working, protecting itself!

5. The sound system is making a terrible noise:

i.If a microphone is being used in the system you may be hearing feedback. Turning down the level of the microphone and/or repositioning it may help. Using EVOi.net you can start the Anti Feedback control built into EVOi.324.

ii.Is tape deck playback level up? Electrical feedback may be present. Try lowering the tape deck playback level. Check that the tape deck is not connected to the record outputs.
