Featuring 4 independent VHF receivers in one convenient, rugged, all-metal single rack space, the 401X Quad wireless system makes operating 4 wireless systems at the same time easier than ever. This particular wireless mic system comes with 4 HM-1 headset mics and 4 WLT bodypack transmitters. The versatility of the Nady 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' optimum line-of-sight operation.

The Nady HM-1 headsets are miniature headworn dynamic mics that set a new performance standard. The cardioid, polar pattern these HM-1 headset mics feature an adjustable gooseneck which can be set at any angle. They are extremely light and comfortable; visually unobtrusive; and stay secure and stable even when moving, dancing, or shaking your head. They have an XLR connector and include a 3' cable which securely locks into the included WLT bodypack transmitter to give you true, hands-free 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.

feed back hurts my ears


from Murrieta, California

Comments about Nady 401X Quad HM-1 Headset Wireless System:

After haveing been involved in several drama and broadway productions i noticed that all of the people in auio-tech would use this same wireless microphone. it sounds supreme and broadcasts through any soundboard you need it to. these headsets tebd to pick up feed lots of back when someone in the audience is using a cell phone(texting) or ipod.
