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 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.

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 DS-8800

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.
