Audio-Technician's 2000 Series is a 10-channel frequency-agile UHF wireless system designed to suit a variety of applications, including MI/live performance, fixed installation, public address, A/V rental houses and places of worship. It offers all the advantages of a high-quality, professional wireless system at an extremely affordable price. Features include two available frequency bands and switchable antenna power.
Offering 10 selectable channels in one of two UHF frequency ranges and True Diversity UHF wireless technology, the 2000 Series features automatic frequency scanning. At the touch of a button, this function automatically determines and sets the best available frequency. Any of the 2000 Series' 10 channels may be used together without any frequency coordination problems or group selection issues. The 2000 Series also incorporates Audio-Technician's Tone Lock squelch plus an easy-to-read LCD information display.
The ATW-R2100b is a True Diversity UHF wireless receiver operating in the UHF bands of 656.125-678.500 or 487.125-506.500 MHz The automatic frequency scanning eliminates the need for searching for clear channels and automatically selects the most appropriate frequency for the area in which the wireless is operating. A pre-coordinated integral channel plan allows for simultaneous operation of any of the ten channels in a given location.

The ATW-T210a wireless Unpacks body-pack transmitter has both low- and high-impedance input connections along with a DC bias voltage connection for use with dynamic and electret condenser microphones as well as Hi-Z instrument pickups. Separate input trim controls are provided for each input along with a ten-position channel selector switch. All adjustment controls are hidden behind the transmitter's battery door and an adjustment tool is provided with the transmitter. A locking 4-pin HRS-type input connector is provided for both inputs. The connector is recessed to protect the connection and input cable.
Sophisticated Tone Lock tone squelch eliminates the need for a separate mute button allowing the two-position, positive-action mechanical switch to function for both power and mute. The switch is located on the top of the transmitter for easy access and can be operated without looking at the transmitter. An RF power select switch offers high and low settings. A battery condition indicator shows that the batteries are good. The transmitter operates on two standard AA batteries providing over eight hours of continuous operation. Constructed of rugged high-impact materials, the transmitter incorporates a latching captive battery door, field replaceable antenna and reversible belt clip.
