Review: Good budget mics - Have been good for an inexpensive setup. Have used them through one channel and through four. No drop out or interference problems. Not high end, but they are good mics on a budget
Review: Shockingly good - There's no disputing these are very basic and very cheaply made. 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. Using the low traditional wireless microphone in the complex environment or when the signal of the microphone is week or the microphone is closured, the squelch circuit many suddenly opened which result the receiver send out a strong burst of noise.
- It ideal for church, small DJ KJ stage, birthday wedding or family party, conference, classrooms, small karaoke night etc.
