Overview

Featuring four independent VHF receivers in one convenient, rugged, all-metal, single-rack space housing the Nady 401X Quad wireless system makes operating 4 wireless systems at the same time easier than ever. This particular headset wireless mic system comes with four HM-20U headset mics and 4 WLT bodypack transmitters. The versatility of the 401X Quad extends to its dual antenna jacks which allow you to have either onboard or remote antennas. The rock-solid VHF performance is complemented by unmatched transparent audio with 120dB dynamic range and up to 500 feet optimum line-of-sight operation.

The Nady HM-20U miniature unidirectional condenser headset microphone is optimally designed for singing and speaking applications, even in noisy environments. Its small, lightweight design makes it ideal for handsfree use with minimum visibility. Perfect for singer-musicians (drummers, keyboardists), vocal/dance performers, DJs, television announcers, public speakers, and aerobics instructors. The Nady microphone has a 3.5mm phone plug that securely locks into the included WLT bodypack transmitters to give you true, handsfree operation. The WLT bodypacks work for up to 15+ hours on a single 9V battery sold separately) and have low-battery LED indicators, audio muting, and easily accessible volume control.

Durable and worthwhile

By Raeanna

from Scottdale Pa

We had bought these for school to try for our auditorium. The first 4 hours we had them we played around with them and tried the different frequencies and settings. Basically they worked very well. Not alot of feedback or interference from other electronics or radio signals. Strong clarity through our PA system we use as well at school. We can use all four at the same time on different channels or the same. Battery life lasted us about 6-8 hours on the original 9 volt battery. Belt pack feels durable, not a cheap piece of plastic like some others i have seen. We accidentally dropped one from about 8 feet and it only left a small scuff mark from where it landed. No drop in sound or loss of signal either. A little bit pricey but i really think they will last a good while. And for four of them really isnt too bad compared to other units.
