Mipro has included a full-color vacuum fluorescent display panel on the front of its ACT-818 1/2RU single-channel UHF mic receiver to assist with setup and operation. The rear panel provides a very handy ground lift switch on the XLR output. It and the unbalanced 1/4in. output connections also are switchable between mic and line audio levels and there is a SPDIF digital output, as well. The antenna ports have an 8VDC bias that can be used to power antenna signal boosters. The system also offers 10 built-in SmartEQ presets and 256-bit encryption. The unit works with the ACT-80H handheld and ACT-80T bodypack transmitter as well as the rechargeable versions 8Ha and 8Ta.
The new PCX U-1002 from Peavey features auto scan on the half-rack space receiver and the system can frequency synchronize it with the transmitter in a quick setup. The rear panel includes both XLR and 1/4in. output connections and they can be switched between line and mic levels. The antenna connections are DC powered to operate antenna-boosting equipment and the front-panel color LCD is used for settings as well as battery level, channel, and audio/RF signal level displays. Multiple receivers can be daisy-chained on a network line for centralized control and monitoring. The PCX U-1002 system can include handheld and bodypack transmitters for vocal and instrumental roles.
Making its debut at ISE this year, the Executive Elite wireless mic system from Revolabs can be set up as a 4- or 8-channel installation using a distributed architecture, which connects the remote antenna receiver and the base unit on Cat-6 cable. Its PoE feature simplifies installation and the rechargeable microphones can provide up to 12 hours of continuous talk time. The receiver can be linked to many others, expanding the system’s total channel capability to 80. Conference participants can use either gooseneck or wearable microphones, and the system can be controlled remotely or through a local connection.
Sacom’s idea behind the 8-channel DS8000 digital wireless microphone system is expandability through modular configuration. A 1RU rack frame holds up to eight of the receiver modules and works with any of the system’s rechargeable handheld, bodypack, and gooseneck table base transmitters. The digitally encrypted signals can be sent through up to eight linked receiver rack frame units operating on a single pair of distributed half-wave antennas. The free software package can control and monitor the system through USB, RS-232, or Ethernet, and the transmission power can be adjusted for 1, 10, 25 or 50mW.
For a very sophisticated and high-end wireless system loaded with features, Sennheiser offers the Digital 9000 system operating in the UHF band with up to 40 channels between 470MHz and 798MHz. With a built-in graphical spectrum analyzer and RF level recorder, the EM 9046 receiver can find the best channels in today’s challenging RF environment. The SKM 9000 handheld transmitter can be fitted with any of 12 different microphone heads including the evolution wireless/2000 series and Neumann capsules. The SK 9000 bodypack transmitter has a magnesium case, and it can accept microphones and instrument connections on a 3-pin Lemo connector.
The BLX Wireless System from Shure is intended to be configurable to suit any specific user scenario with simple setup and connection. Built around the BLX4 single-channel and BLX88 dual-channel receivers, the system can include any combination of instrument, lapel, or head-worn microphones working with the BLX1 bodypack transmitter. The BLX24/SM58 is a handheld version that incorporates the well-known Shure SM58 microphone head. Up to 12 compatible systems may be used on each frequency band and the QuickScan feature finds the appropriate channel. Each receiver has both XLR and 1/4in. output connections, and the transmitters can run up to 14 hours on one set of AA batteries.
For touring professionals and upscale installations, Sony has developed the DWX Digital Wireless series with rackmounted DWR-R02D dual-channel UHF receiver that can be paired with Sony’s DWM02 handheld, DWRS02D bodypack, DWTB01 bodypack, or DWTP01 plug-on transmitters. For field operation, these transmitters can be used with the DWRS02D/42 battery-operated receiver. For those who prefer to travel lighter, there is the DWZ Digital Wireless system with small, mobile receivers such as the ZRXHR50 half rack unit that can be used with a range of belt-pack, handheld, and instrument transmitters using the 2.4GHz ISM band.
Designed to allow economical entry into the wireless microphone realm with easy operation, the Trantec S4.16 Series from TOA Electronics can be purchased as either the Q-S4.16H for handheld operation or the Q-S4.16L with a lapel mic and bodypack transmitter, which includes a switch for microphone and instrument input levels. The system provides 16 channels within the 616-630MHz range with simultaneous operation of up to eight transmitters. The receiver has both XLR and 1/4in. connectors and it allows the output audio on the XLR to be switched between line and mic level. Diversity reception and RF signal strength can be monitored on the front panel. The transmitters each operate at a 10mW RF power level.
