OK at first I thought this is the worst designed battery compartment ever. It did not make contact with the terminals well enough to keep contact. I was about to return it when I tried one last time. This time I pushed in and down and I heard a click... and now I think its the best designed battery compartment ever. In and down.
Well this is a must tool for any tech, sound engineer or musician if you are a sole traveller. Bands, buy one. At this price its the cheapest of its kind. But the quality of the unit is unbelievable. This is a tank.
Plug one end of the cable into the correct socket. Plug the other end to the correct socket for it. And config seems to be catered for. Turn the switch to the numbers. The corresponding light will light up. Now you will need to know a little about how your cables should be wired but for guitar leads and balanced xlr, 1 to 1 , 2 to 2 and 3 to 3 should be the norm.
If the connectors are not standard, you can even use the supplied probes to test continuity. It beeps. So no need to hold the probes steady to glance at a light.
With connectors in place, shake the cable whilst testing and you will see if theres a break.
Now it is not going to fix your cables, but it will tell you which ones are good to use and which ones need to go to the repair man or the bin.
Its big and bulky to allow for speakon cables. It is worth every penny.
All you need is a 9v battery. It even has a built in battery check.
