EVOi.324
20
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.
