CONNECTIONS
WARNING:
loudspeaker connections should be only made by qualified and experienced
personnel having the technical know-how or sufficient specific instructions (to ensure
that connections are made correctly) in order to prevent any electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers when the amplifier is
switched on.
Before turning the system on, check all connections and make sure there are
no accidental short circuits.
The entire sound system shall be designed and installed in compliance with
the current local laws and regulations regarding electrical systems.
‘Compact’ series loudspeakers are designed for indoor use only. If installed
outdoor, loudspeakers shall be protected against water.
On each rear panel:
-
A switch to select either ‘FULL RANGE’ (one amplifier and use of the internal
crossover) or ‘BI-AMP’ (bi-amplification and external crossover)
-
2 sockets (input and output, linked in parallel) for ‘Neutrik Speakon NL4’
(4-pole) plugs.
‘FULL RANGE’ MODE
The impedance value of each loudspeaker is 8
Ω
.
Connect the positive wire (amplifier ‘+’ output) to the pin 1+ of the SPEAKON connector.
Connect the negative wire (amplifier ‘–’ output) to the pin 1– of the SPEAKON connector.
The pins 2+ and 2– are not used.
‘BI-AMP’ MODE
Two amplifiers are necessary (one for low frequencies, one for high frequencies) and an
external crossover.
See in the specification table the impedance of each way, the handling power and the
suggest crossover frequency.
Connections:
-
Low frequency amp output to the pin 1+ of the SPEAKON connector
-
Low frequency amplifier – output to the pin 1– of the SPEAKON connector
-
High frequency amp output to the pin 2+ of the SPEAKON connector
-
High frequency amplifier – output to the pin 2– of the SPEAKON connector.
