AC mains connection
• Make sure the mains power switch is off ('0').
• Check that mains voltage corresponds to the voltage indicated on the panel.
• Use only the factory supplied mains cable or, if a different plug style is
needed, a suitable cable with a ground connection and marked with the
safety approvals valid in the country of use.
• Leave enough room to get to the mains power socket and the mains
connector on the back panel. As long as it is plugged in there can be
dangerous electrical potentials inside the device, even when the mains
switch is in the '0' (off) position and the power indicator is off so, before
undertaking any sort of maintenance work etc., always make sure it has
been unplugged from the mains socket.
For details about mains power cable and ac link cable wiring,
refer to par. 3.2.
Connection to mixer
• If the mixer has XLR balanced outputs: use standard balanced XLR
connectors.
• If the mixer has XLR unbalanced outputs: in this case, unless using a
Montarbo mixer, make sure that the XLR outputs on the mixer are
unbalanced to IEC 268 standard 1 = GND, 2 = HOT, 3 = GND.
• If the mixer has JACK balanced outputs (stereo jacks):
it is possible to use stereo jack-XLR adapters, wired according to IEC 268,
pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring.
• If the mixer has JACK unbalanced outputs (mono jacks): use suitable
Jack-XLR male adapters unbalanced according to IEC 268 pin 1 = ground,
pin 2 = tip, pin 3 = ground.
Connection of the full-range cabinet SPOT2500T to the bass cabinet
SPOT15B
Use the cable supplied with the system.
If longer cables are needed, they may be assembled following the wiring
instruction of par. 3.3.2.
Connection to a sub-woofer
• If the sub-woofer has an XLR balanced input (female): use a standard
balanced XLR cable (male-female).
• If the subwoofer has an XLR unbalanced input: make sure that the input is
unbalanced according to IEC 268 standard 1 = ground, 2 = hot, 3 = ground.
• If the sub-woofer has a JACK balanced input (stereo jack):
it is possible to use a stereo jack-XLR adapter, wired according to IEC 268
pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring.
• If the sub-woofer has a JACK unbalanced input (mono jack):
use suitable Jack-XLR female adapter unbalanced according to IEC 268
pin 1 = ground, pin 2 = tip, pin 3 = ground.
• Always use only heavy gauge, high quality SHIELDED cables (signal cables).
• Always make sure that the mixer and the powered enclosures are
switched off before connecting them.
This will avoid annoying noises and signal peaks, which can also be
dangerous for the enclosures themselves.
For details about signal cables wiring, refer to par. 3.3.1.
