Despite anxiety over the wireless frequency crunch that's slated for February 2009 — the date that the FCC has chosen for analog transmission to cease — the demand for wireless systems keeps growing, particularly in live sound applications.

Wireless system manufacturers continue to meet the challenge of developing more efficient and user-friendly systems, even as available frequencies become increasingly scarce. We surveyed manufacturers' current top-of-the-line handheld units for live sound and found a wide array of systems and features, priced for any application.

AKG's (www.akgusa.com) WMS 4000 system operates in the 650 to 790MHz UHF range and is priced from $1,474. The WMS 4000 can access up to 1,200 channels (depending on conditions) for using more than 50 systems at once. The HT 4000 handheld comes in a choice of three dynamic and three condenser capsules. It features jog wheel control and a backlit display, showing battery life, frequency, channel/preset groups, gain setting and mute. The optional CU 4000 charging station comes with two “Smart Batteries.” The transmitter operates for 15 hours on two AA alkaline batteries or 12 hours on two AA rechargeables. The half-rack SR 4000 receiver has front-mount antennae and a backlit LCD indicating audio input, RF level, mute, frequency, group or user ID, and diversity switching, along with battery life and setup parameters. The receiver has balanced XLR and unbalanced ¼-inch outs and a data port for computer monitoring/control. An optional network hub interfaces with Harman Pro's HiQNet system. The SR 4000 accommodates two diversity antennae; also available are a master antenna pair (directional and omni, with/without booster), an antenna splitter and multi-coupler.

Audio-Technica Artist Elite 5000 Series comprises two cardioid condenser handheld transmitters and a dual receiver.

Audio-Technica's (www.audio-technica.com) Artist Elite 5000 Series AEW-5255 ($3,999) includes two AEW-T5400 cardioid condenser handheld transmitters and one AEW-R5200 dual receiver with XLR output, ¼-inch TRS balanced jack and a headphone output.

Sabine's Smart Spectrum system combines spread-spectrum filtering with a variation of FM technology for a more interference-resistant system with more simultaneous channels. Each system includes FBX Feedback Exterminator, parametric filters, Mic SuperModeling, a compressor/limiter and adaptive de-esser. The rackmount SW2-NDR receiver has two rear-mounted coaxial dipole antennae. SW70 Series handhelds use Audix OM3 or OM5 dynamic capsules or a Voice Technologies condenser. Accessories include rackmount antenna distribution for up to six receivers and a low-profile extension antenna for unobtrusive wall-mounting. Transmitter functions can be controlled from the receiver, the included Windows remote-control software, from Crestron or AMX touchscreens or any serial-based controllers. Sabine rechargeable batteries offer nine hours per charge, or the transmitter can operate for 15 hours on two AA alkaline cells.

The UHF Synth Series Six from Samson Technologies (www.samsontech.com) uses two independent, synthesized receivers ($2,199.99) in one rackspace and works with a variety of popular handheld mics, offering 101 channels in two frequency spectrums — 782.125 to 793.875 MHz and 794.125 to 807.875 MHz. A spectrum-analyzer feature scans for the clearest available frequencies, and up to 96 systems can operate simultaneously at 1mW power or up to 22 systems at 10mW power. The receiver has balanced XLR and unbalanced ¼-inch outs, and its backlit LCD shows channel and frequency selection, mute, tone, squelch, receiver ID and more. Its power supply senses voltages automatically. Transmitters ($609.99) are powered by AA batteries. The system can be controlled remotely with a PC using Samson's WSM (Wireless System Manager) software.

Sennheiser (www.sennheiserusa.com) followed up its SKM 5000 with the SKM 5200-UHF ($2,115). The new transmitter features 7,200 frequencies, a menu-driven user interface in a backlit LCD, three selectable low-cut filters and mic sensitivity adjustable in 1dB steps. The transmitter's LCD indicates battery-charge status, which is also transmitted to suitable receivers. The SKM 5200 offers a fixed channel bank and a variable bank. The fixed bank can be ordered with 20 preset frequencies to allow the transmitter to be integrated quickly into existing RF environments. Users can program up to 20 UHF frequencies in 5kHz steps into the variable bank. The system is compatible with five condensers and one dynamic handheld — as well as Neumann's KK 105 and KK 104 capsules — with omnidirectional, cardioid, wide-cardioid or supercardioid pickup patterns. Its HiDyn Plusnoise reduction system keeps RF noise to a minimum. The SKM 5200 offers more than eight hours of operation using the rechargeable battery pack or standard alkaline batteries.

Prices for Shure's (www.shure.com) UHF-R system begin at $3,043 for a single-channel system with an SM58-equipped transmitter.
