Audio Technica ATW2120 (Audio Technica ATW-2120) Handheld Wireless System
The ATW-2120 UHF Handheld Dynamic Microphone System includes the ATW-R2100
receiver, plus the ATW-T220 handheld microphone/transmitter.
The new 2000 Series UHF True Diversity Wireless Microphone Systems are
Audio-Technica's latest entry in its extensive line of professional wireless
systems. The 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 true diversity operation, easy setup, automatic frequency scanning with
interference-free performance, and all the advantages of a high-quality,
professional wireless system at an extremely affordable price.
Operating in the 600 MHz frequency band (656.125-678.500 MHz, TV channels 45-48)
with 10 selectable frequencies 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
(open channel) -- particularly useful when employing multiple wireless systems,
thereby avoiding interference and intermodulation. When there is a need to
utilize multiple wireless systems simultaneously, any of the 2000 Series 10
channels may be used together without any frequency coordination problems or
group selection issues. Additionally, the 2000 Series incorporates
Audio-Technica's digital Tone Lock squelch plus an easy-to-read LCD information
display, which provides convenient visual indications of settings and operation
status.
The ATW-2120 UHF Handheld Dynamic Microphone System includes the ATW-R2100
receiver, plus the ATW-T220 handheld microphone/transmitter. The ATW-T220
microphone is engineered with the same capsule as Audio-Technica's acclaimed PRO
41 microphone, providing a focused vocal pickup while offering superior gain
before feedback.
The true diversity ATW-R2100 half-rack receiver features an all-metal housing
for superb shielding, as well as dual independent receiver sections. Its true
diversity operation selects the best signal from the two independent receiver
sections, thus reducing dropouts and minimizing multipath distortion. The
ATW-R2100 offers 10 PLL-synthesized UHF frequencies, advanced digital Tone Lock
squelch, soft-touch controls with LCD information display, detachable UHF
antennas, plus a rack-mount kit. Also included is a transmitter battery
indicator LED, XLRM-type balanced and 1/4 in. unbalanced outputs, plus a
ground-lift switch.
The ATW-T220 handheld microphone/transmitter features the same resilient capsule
as A-T's popular PRO 41 Cardioid Dynamic Microphone. This element assembly, part
of the R & D for A-T's acclaimed PRO Series, was specifically designed with
high-performance specifications in mind for clarity, volume, and durability.
Providing a natural, focused vocal pickup while supplying excellent feedback
rejection, its internal shock mounting reduces handling noise, making the
ATW-T220 ideal for close-up vocal use in live performance settings. Whether used
as a handheld mic or mounted on a microphone stand, the ATW-T220 handheld
microphone/transmitter excels by virtue of its rugged metal construction, the
included AT8456a Quiet-Flex stand clamp, and extended battery life --
approximately nine hours, powered by two 1.5V AA batteries.
