B1 speaker wire problems...

I have 2 L1B2 systems. Suddenly all 4 of my B1 blue wires seem to have developed shorts. 3 cables are completely dead and one needs to be jiggled to get the signal in. Release the pressure and it cuts back out.

Is this a known issue?

What should I get to test the 4 Wire Speakons to the B1s? Are they all the same?

I am looking at the Hosa CBT277. ($77)

Hi DJGuy,
We've seen some past B1 cable quality problems which, because of input from folks like yourself, we've since resolved.

I'm fairly confident that the connector and wires in the cable assembly are OK. The problems we were having were related to the actual connection of the wire leads to the Speakon connector. Problems would be obvious in one case- the bass module cuts out. The second case would not be so obvious- the EQ to the B1 and L1 would be wrong and would make the system perform and sound poor.

So, if you have a moment and a screwdriver, we can fix these cables together.

Remove the rear shell of the connector by unscrewing it. (See the pic below, not the exact connector but similar). We use a 4-wire connection so what you need to do is re-attach, possibly restripping first (need to use a wire stripper), the wire to the connector terminals. There are four terminals +1, -1, +2, -2. Each wire needs to be appropriately connected to the same terminal on each end of the cable. Luckily, no soldering is needed. These Speakon connectors have screw terminals. All you need to do is unscrew the terminal using a screwdriver, reinsert the bare wire, and then tighten the terminal.

If you have any questions about this, don't hesitate to ask!
