ENGLISH
The HDL line arrays Systems are designed to operate in hostile and demanding situations.
Nevertheless it is important to take extremely care of the AC power supply and set up a
proper power distribution.
The HDL line arrays Systems are designed to be GROUNDED. Always use a grounded
connection.
The HDL amplifiers are designed to work within the following AC Voltage limits:
230 V NOMINAL VOLTAGE: minimum voltage 185 V, maximum voltage 260 V
115 V NOMINAL VOLTAGE: minimum voltage 95 V, maximum voltage 132 V.
If the voltage goes below the minimum admitted voltage the system stops working If
the voltage goes higher than the maximum admitted voltage the system can be seriously
damaged. To obtain the best performances from the system it is very important that the
voltage drop it is as low as possible.
Make sure that all the system is properly grounded. All the grounding points shall be
connected to the same ground node. This will improve reducing hums in the audio system.
The module is provided with a Powercon outlet to daisy chain other modules. The maximum
number of modules that is possible to daisy chain is:
16 (SIXTEEN) OR 4 HDL 18-AS + 8 HDL 20-A MAXIMUM OR 8
HDL18-A.
230 Volt NOMINAL VOLTAGE: minimum voltage 185 Volt, maximum voltage 264
Volt (for UK 240V+10%)
115 Volt NOMINAL VOLTAGE: minimum voltage 95 Volt, maximum voltage 132
Volt.
A superior number of modules in daisy chain will exceed the Powercon connector maximum
ratings and create a potentially dangerous situation.
When the HDL line arrays systems are powered from a three phase power distribution it
is very important to keep a good balance in the load of each phase of the AC power. It is
very important to include subwoofers and satellites in power distribution calculation: both
subwoofers and satellites shall be distributed between the three phases.
