System Connections
The supplied cables enable a whole system to be connected from the Sub&Hi outputs on a B3 amplifier.
Make sure you use the correct cable from the amplifier to B15 and from the B15 to B12.
Use the 8 meter cable to connect from the Sub&Hi out on the B3 amplifier to a speakon on the B15.
Use the 2 meter cable to connect from the spare speakon on the B15 to the lower speakon on the B12.
When linking a B12 cabinet to another B12 cabinet, use the top speakon as the link out and use the other
B12's top speakon as the input. A cable wired +1, -1 to +1, -1 or +2, -2 to +2, -2 can be used to connect the
two B12's when linking via the top input speakons.
The B15 is wired +1 and -1 for its input. The top B12 input can get its input from both +1 and -1, or +2 and -
2. The bottom B12 input is wired +2 and -2 for its input.
The speakons on the B15 are wired in parallel, so either speakon can be used as the input, the other speakon
can be used as a link output. The same applies to the B12, but only pins +2 and -2 are linked from the
bottom to top speakons. In an installation where B12's will not be connected via a B15 cabinet, use pins
+1 and -1 on the top speakon input on the B12 and the Hi outputs on the B3.
Notes
The B12 enclosures logo is spring loaded and rotatable. This allows the logo to be displayed upright
when the cabinet is used in either vertical or horizontal positions.
Precautions
1. Install B12 and B15 enclosures in a dry environment, do not expose the cabinets to rain or moisture.
2. When connecting the B12 to the B3 amplifier do not connect the B12 to the Sub&Hi out directly.
Connect via a B15 or to the CH1 and CH2 Hi outputs using the B12's top input speakon.
3. If connecting a B12 to a B15 a 4 way speakon to speakon cable must be used from the B3 to the B15. If a
4 way cable is not used the B12 will not be connected.
4. Only use a speakon to speakon cable wired +2 and -2 to +2 and -2 when connecting the B12 to a B15
sub. If a cable wired 1+ and 1- is used the B12 will receive the same signal as the sub.
