Beyerdynamic TG 1000

Beyerdynamic TG 1000

The TG 1000 24-bit digital wireless system from Beyerdynamic operates in the UHF band (470-489MHz) with automatic frequency selection, encrypted transmission, browser control, and monitoring through an integrated web server in the dual receiver. Its white OLED front-panel display stands out in high ambient light and up to 12 of the units can be cascaded on one set of antennas looping through them. The handheld transmitter has an anodized aluminum housing and an IR receiver to sync channels with the receiver. Channel/group and battery status are shown on its display. To connect mics and instruments, the bodypack transmitter uses a mini 4-pin XLR and it has an internal switch to select 0dB or -12dB signal attenuation.

Clockaudio CW9006T

Clockaudio CW9006T

Clockaudio has a simple, easy solution for podium, stand, and conference microphones with the CW9006T mic base transmitter unit and its integral XLR connector, which can plug directly into a handheld mic or connect to the bottom of an XLR equipped floor stand. The other base models have 3-pin mini connectors and all table base models include a programmable pushbutton switch and LED indicator. Any two of the table base transmitters can be charged in the CU-2 Intelligent Battery Management System. These are used with the CW9000R diversity receiver, which provides balanced and unbalanced audio outputs along with a front-panel level control.

Earthworks Audio WL40V

Earthworks Audio WL40V

When specialized performance is needed with existing handheld wireless microphones, Earthworks Audio can respond with the WL40V back-electret condenser wireless capsule and its hypercardioid pickup pattern. Compatible with specific handheld mics from Lectrosonics, Sony, Line 6, and Shure, the WL40V easily screws onto the microphone body using a 25in. x 28-thread pitch. The case is hardened against 500MHz and 2.4GHz interference, and the unit exhibits uniform frequency response at 0, 45, and 90 degrees with 135dB SPL maximum acoustic input. Weighing 90 grams, the WL40V is well balanced for handheld mics.

Electro-Voice R300

Electro-Voice R300

The R300 system from Electro-Voice combines very simple setup and operation with some professional features such as one-touch ClearScan and EZsync transmitter update. The receiver quickly finds a clear local channel and then uses its IR link to match the transmitter’s frequency to it. The R300-L system uses the BP-300 bodypack transmitter and ULM18 directional lapel mic while the R300-HD includes the PL22 handheld mic. The R300-E is a head-worn system featuring the HM3 microphone. The transmitters have a backlit LCD display with a battery level gauge. The receiver’s half wave antennas can be removed and remoted when the unit is used with the APD4+ antenna distribution system.

Gemini Sound UHF-4200M

Gemini Sound UHF-4200M

Housing two 100-channel UHF receivers in a single small case, the UHF-4200M dual wireless handheld mic system was designed by Gemini Sound to provide a range of about 250ft. and allow either automatic or manual frequency selection. Up to eight channels can be used by transmitters equipped with power/mute buttons. The receivers have mixed signal 1/4in. and individual XLR output connections. On the front panel, there are bright channel displays and individual channel output level controls along with audio and RF signal indicators. The rear panel also provides a line/mic output level switch.

Lectrosonics HH Digital Hybrid Wireless

Lectrosonics HH Digital Hybrid Wireless

The Lectrosonics HH Digital Hybrid Wireless handheld transmitter has selectable RF power (50mW/100mW) and a wide range of receivers with which it can be configured to be compatible. To suit specific acoustic and SPL environments, the transmitter can be fitted with a variety of standard thread mic heads from Shure, Earthworks, Electro-Voice, and other companies, as well as Lectrosonics. The transmitter sends digital audio over an analog FM radio link to reduce compander artifacts and provide flat frequency response. It also has a very handy talkback feature in which a button on the transmitter can direct the receiver to switch the mic signal to a secondary channel for cueing or other uses.
