Are my speaker cables compatible

    I just bought two speaker cables with Neutrik NL4FX connectors. They work fine for my Genz-Benz GBE, but I get no sound when I use them with my Markbass LMII. My existing cables, which have the NL2FC connectors, work for both amps. I've contacted Markbass but have not heard from them. Is there any reason the NL4FX should not work with the Markbass amp? I'm hooking the heads up to Accugroove cabs, in case that makes any difference.

    Strange that it works on one amp and not the other. How are the connectors wired? They should be +1 / -1 on both ends...

    Hmmm, does not make sense. All GBE amps are wired 1+/1- so this confirms that your NL-4 cable is wired 1+/1-. The NL2 only has 1+/1- terminals so that can't be mis-wired. I'm assuming that you are using the same speaker cabinet when testing both amps?

    There are some alternate wiring schemes available on the NL-4, such as 1+/2+ on the amp end and 1+/1- on the speaker end for bridging purposes but this wouldn't work on either of your amps.

    Puzzling indeed. Let us know what you find.

    Thanks for the replies. I emailed the people who made the speaker cables and they looked up both Genz Benz and Markbass to confirm they both take 1+/1- which is how the cable connectors were wired. Nobody seems to know how this condition could exist. Fortunately I have a few NL2's, so I guess I won't worry about it.

    Couldn't you just open up the connector and look at what's going on? You're pretty sure the connectors are genuine Neutrik right?
