Alto Radius 100 Handheld Product Description

When you need a wireless microphone, you need it to come through with consistent, reliable performance. Excuses won’t do. Only performance counts.
Radius 100 is an easy-to-use UHF diversity wireless microphone system that is available in three versions and provides reliable, crystal-clear sound for a wide range of professional vocal applications. Alto’s switching diversity receiver design utilizes two separate antenna systems for uncompromised wireless performance. If one antenna experiences signal interruption, the receiver instantly switches to the second antenna. This assures you of an extremely stable, reliable wireless signal,with virtually no chance of dropout or interruption. This is the promise of wireless performance-delivered!

    Dual-antenna UHF diversity receiver for increased reliability and signal consistency
    UHF band operation: 520 - 937.5MHz (regionally selected)
    Receiver includes a high-visibility back-lit LCD display: Displays RF frequency and channel, AF and RF signal levels and other critical functions
    Single-button scan feature for quickly identifying the optimal operating frequency
    Sync function automatically synchronizes transmitter and receiver frequency
    Squelch control for minimizing background noise during silent periods
    Front-panel rotary volume control
    Balanced XLR and unbalanced ¼-inch mic or line-level outputs.

Brilliant piece of kit.
Having now had this for 6 month I can give and honest review. It is simply a Wonderful set, I've upgraded from a KAM dual mic set which was a constant stress with a fixed frequency and drop outs galore! The peace of mind I have now is worthy of the price tag, twin receivers that cover any chance of a drop out and the ability to shift frequencies at will is an amazing feature that admittedly I haven't had to use yet but it's good to know its there. Runs on double AA batteries as well, which is a lovely touch. Crisp, Clear vocals and sharp response from ththe actual mic are as expected with an Alto system. All round great microphone set.

Impressed by the quality and sound for the price.
Bought this to replace an Audio Technica ATW R700 handled mic and this is superior for less cost! One aspect I noticed is that there is no gain control on the Mic but as a condensor mic I've not found it a problem yet. Used three times at sunday services now.
