But cut to the chase... ...we all want a mic to work with sufficient gain to be low-noise, that is to say 'usable'. These do. I bought them in a pinch, not having the requisite dollars to replace the failed "Better Brand", but honestly, these will stay in the rack for as long as they live. I'll never produce an $800/seat rock show, but for weddings and the like in various places, these really are more than sufficient. Battery life is as good as the 'Better" when running 3500mWh rechargeables. ## Features - Debra Audio AU400 4 channel wireless microphone system.(Two set freuqncy point: A- 501/511.5/524/538.5 B-506/517.5/531/546.5) - These series products adopt UHF frequency and use the international standard common frequency which can be used in all over the world. - Due to the low frequency and many reasons, traditional wireless microphone usually disturbed by many factors especially by the variety of harmonic which send off by the CD/DVD/VCD/LD and other any digital equipments. - Squelch circuit usually analysis the intensity of the RF frequency channel instead of the noise and the needed signal.

If only one system needs to be used, choosing either A or B has no effect. But if you need 2 systems to use together, you need to choose one A and one B. Because the same frequency points will interfere with each other. **Q: Can we purchase handheld wireless mics to use with our bodypack b system?** A: Yes,friend. But you need contact us in our e-mail. **Q: Will rechargeable batteries fit in the microphones since they are bigger?** A: Sure Rechargeable batteries are even better than the one time use batteries Just keep a back up , nearby set of batteries but the whole system is super **Q: I need a system with 1 handheld & 3 headsets. The closest configuration is 2 handheld & 2 headset. Can I purchase extra headset/bodypack?** A: Additional earphones/bodypacks can be purchased.
