AC Power Requirements
In the United States, the EVOi.324 is supplied with an
Edison type plug. For other countries, the correct plug must
be used in accordance with the local requirements. For
Europe and the rest of the world the correct AC supply lead
will be supplied.
Voltage Requirements
EVOi.324 will operate continuously provided the AC
Voltage falls within the following ranges:
Standard AC Voltage Voltage Range Frequency
120v +/- 10% 50/60Hz
230v +/- 10% 50/60Hz
Brown-out Conditions
If the voltage falls below this range, the EVOi.324 will
‘brown-out’. During ‘brown-out’ the audio signal will
momentarily mute during very high level program. Should
the supply voltage permanently remain below this supply
voltage, then the EVOi.324 will shut down. When the AC
supply falls within the above stated ranges, EVOi.324 will
switch on again, and operate normally.
To avoid ‘brown-out’ EVOi.324 should be operated with an
AC supply that adequately falls within the above stated
ranges.
Current Requirements
EVOi.324 will not draw a continuous current. Acting as a
dynamic load on the AC supply, the current drawn will vary
dependant on the operating level, e.g. quiet levels and loud
levels in the program.
Understanding the amount of current drawn is essential
when using EVOi.324.
The EVOi.324 is capable of drawing peak currents of up to
18 Amps. Any cabling used should be of a suitable gauge to
reflect this. Inadequate cabling can cause large voltage
drops over distance and potentially cause ‘brown-out’.
