SAFETY PRECAUTIONS

The VIBE-15 can easily reproduce sound pressure levels (SPL) sufficient enough to
cause severe and permanent hearing damage. Always protect your ears when you
are exposed to SPL in excess of 85dB!
Be sure that your power amp is turned off before connecting the speakers.
The woofer and tweeter are not protected against humid and rain. Therefore this
speaker is intended for indoor use only, use of this product outdoors, in humid
conditions, voids all warranties.
Always mount this speaker in safe and stable way.
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!
CONNECTIONS
The VIBE-15 has two Speakon® type connectors. Both connectors are connected in
parallel. This means that you can connect a second VIBE-15 in parallel.
Speakon® wiring is made as follows:
• POSITIVE
= +1
• NEGATIVE =
-1
Attention: when a second speaker is connected, the impedance drops from 8Ω to
4Ω! In most cases you can only connect 2 cabinets together. However, if your
amplifier supports 2Ω loads, you can connect up to 4 cabinets to each amplifier
output.

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.
