LTA is happy to offer premium DC cables, the same cables we use at audio shows when we want to sound our best. Made with high-purity Audience wire.
We've also upgraded our standard DC cables. They're made with well-regarded large gauge star-quad cable, which gives low resistance and good EMI rejection and is known to be one of the best cables to use for DC umbilicals.
Our cables are terminated at both ends with 5.5mm OD, 2.5mm ID locking barrel connectors, which is what we use for the MZ2. These have extended barrels and should work in any jack that takes this size, regardless of whether the jack is locking as well. If you'd like a DC cable with any other termination, or any other length, let us know via email and we'll be happy to accommodate you.
