    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    I see reviewers saying you get what you pay for but I found that not to be true for this system, which was inexpensive, but works great. I guess I shouldn't be surprised as I understand these guys invented wireless in the 70's and certainly seem to be able to provide top value. My 401X works great and the sound is the best that I've heard in wireless. The range is also great,As I've used it sometimes at over 200 feet.

    401X Quad WHT Hand-held VHF Wireless Microphone System

    By Floyd Stough

    from Texas

    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    Three of the channels work beautifully. Channel N (197.15) however, is close to the frequency of other transmitters (either WLAN or security equipment) and causes the unit to sound like a waterfall. By adjusting the receiver for channel 4 to maximum squelch and placing the channel 4 belt pack in standby and leaving it near the receiver unit I am able to use the other three channels. I can use the channel 4 belt pack within a limited range but if it is moved very far from the receiver the waterfall sound takes over. I have two units and this has been true for both of them. It would be a big improvement if there were a switch to TURN OFF individual channels. The unit does perform nicely in all other respects and has great sound quality.
    Audio frequency response - very good.
    Radio frequency response - at least some interference from outside equipment
    Texture and feel of microphones - comfortable and light with great stage presence
    ease of operation - as simple as one could wish
    The 401X is well worth the price. I bought both of my units as used and even the cosmetic scratches were minor. I am very satisfied with the equipment and very happy to be a MusiciansFriend customer.

    output way too high

    By Kruger

    from Maine

    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    I gave it an average quality as I know you get what you pay for. I got them for my karaoke shows as the singers would rather use a cheap wireless than a good mired mic. I had great luck with another inexpensive wireless Nady, so I chose this one. I gave it 4 for features as it has them, but way too high an output. I planned to use the 4 XLR outs Just DJing I have plenty of available channels. Higher line level than a CD player (excuse me for the lack of technical terms) so you can't do much with the gain. They should have been fine for what I wanted them for. I also had terrible luck with reception, even within "line of sight".

    Two sets did not work

    By Anonymous

    from Undisclosed

    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    We purchased this set. One of the channels didn't work. We sent the set back for a replacement. The replacement came and one of those channels didn't work. We ended up asking for a refund and getting the VocoPro 4-Pack rechargeable set.

    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    Our church bought this system for the value and because we also had issues with a lot of cords lying around. This system eliminated this problem and now we can worship with no worries of tripping on cords!!

    Wireless in OKC

    By The Okie

    from Edmond, OK

    Comments about Nady 401X Quad WHT Handheld VHF Wireless Microphone System:

    I bought this system to get a away from all the cables we trip over on stage. This system works well with our PD250 Fender system, in fact it provided a clearer signal to the PA system. The microphone' and batteries hold up well. The reception is excellent even out 200 feet from the stage. I'd recommend this system to any group, a good investment and buy for the money (I bought the VHF model).
