Frequently asked questions
What does each product actually do?
The CT-2 tests audio cables for continuity and pin faults across nine connector standards. The DJD1 converts unbalanced 1/4" instrument and line signals into balanced XLR signals for noise-free studio and live sound routing.
Can I use these together?
Yes. Use the CT-2 to verify your cables are wired correctly before connecting them to the DJD1, which then conditions the signal for your mixing console or audio interface.
Does the DJD1 require batteries or power?
No. The DJD1 is entirely passive and uses transformer isolation, so it operates without an external power supply or batteries.
Who needs each one?
Rental houses, touring crews, and studio techs need the CT-2 for fast cable diagnostics. Solo musicians, guitarists, keyboardists, and any instrumentalist using unbalanced outputs need the DJD1 to reach balanced mic inputs cleanly.
