Audio Ltd. offers a free app allowing main functions via smart devices.

Audio-Technica’s System 10 PRO wireless system—a well-received 2.4GHz platform in a half-rack chassis with two receiver unit slots—has continued to grow. The company now offers two more 2.4GHz transmitters: the ATW-T1006 Boundary Microphone Transmitter and ATW-T1007 Microphone Desk Stand Transmitter, both of which are extremely useful tools in house-of-worship, corporate, theater and a wide range of installed audio environments. At NAMM in January, A-T showed these two new transmitters as part of new packaged configurations.

Audix’s Performance Series of wireless products began shipping last summer and has received impressive reports from the field. Divided into two groups—the 40 Series and the 60 Series—both are available in single-and dual-rack models. Common system features include one-touch autoscan searches; one-touch sync, transmitter to receiver; RF and AF indicators; high-contrast LCD displays; simplified menus; soft keys to control output levels, squelch, pilot, and lockout; choice of XLR or ¼-inch outputs; and a wide selection of handheld, instrument, headworn and lavalier microphone options.

Up to six dual receivers can be cascaded without the need for external antenna splitters. Range under optimal conditions can reach up to 984 feet.

CAD Audio’s CADLive WX3000 UHF Wireless Series package features the D90-equipped handheld transmitter (pictured) and bodypack transmitter for Hi-Z guitar and Lo-Z microphone input, all within a handy polypropylene carrying case. The included CADTone body pack includes Equitek E19 earworn and E29 lavalier microphones. In use, I found the WX3000 to be an intuitive and superb-sounding UHF wireless rig, especially considering its relatively low street price. Its metal-clad handheld transmitter feels especially well made to the touch and resembles handheld transmitters from systems costing hundreds more.

Electro-Voice’s RE-2 PRO Wireless System is a blend of pro-grade features and affordability, featuring one-touch Auto-ClearScan and full programmability. Other features include Posi-phase diversity, over 28MHz operation, XLR mic/line level output, backlit LCD, and a unique “guitar-optimized” mode that is optimized for guitar.

World-class wireless experts Lectrosonics has introduced version 4.0 firmware for its IFBR1a belt-pack receiver, adding new functionality in two distinct user interface modes: Scan mode, exhibiting the original behavior of the IFBR1a receiver where users can locate and store up to five different IFB carrier frequencies; and Direct Entry mode, which takes away the scan capability and replaces it with the ability to program channels into the memories directly via push-button and hex switches. In Direct Entry mode, five additional channel memories are available for a total of ten.

IFBR1a users can identify the difference between a v4.0 IFBR1a in Scan Mode and a v2.4 IFBR1A by a burst of rapid LED blinks at power-on in the v4.0 version, indicating that the unit has two modes available.
