ENGLISH OPERATION MANUAL
JB SYSTEMS 2/18 PSX-15
Parallel connection @ 4Ω: Parallel connection @ 2Ω: (ATTENTION:
not suited for most amplifiers!)
Cables to be used:
You can use readymade cables such as our JB SYSTEMS codes 2-0505 (5m) or
2-0510 (10m) or 2-0525 (25m). Of course you can also assemble the speaker cables
yourself. Take care to use good quality speaker cable with at least 2x 2.5mm²
conductors. You will also need a pair of Neutrik Speakon® NL4FC connectors. This
connector has 4contacts: +1 -1 +2 -2. Only use the +1 and -1 contacts. Your speaker
cable has 2 conductors with different colours. Be sure to connect the same colour on
each side of the cable to the corresponding contact! (+1 to +1 and -1 to -1).
If you inverse the conductors, poor sound quality with a lack of low
frequencies will be the result.
RIGGING POINTS
The PSX-15 cabinets have 4 rigging points using M8 inserts. These can be used to
suspend (fly) the cabinet in the air. For this purpose you can use heavy duty eyebolts
with metric M8 thread. In most cases 2 cables will be attached to the top and one is
used to pull up the back.
Anyway always take special care when the cabinets are suspended. This is
potentially dangerous and should only be carried out by technicians who have perfect
knowledge of the techniques and regulations of rigging speakers!
