Description
The ATW-T220 cardioid dynamic wireless handheld transmitter
incorporates the PRO 41 dynamic element created for professional
live sound venues. The element includes internal shock mounts for
low handling noise. An integral two-stage pop lter within the steel
headcase protects against “p” pops and other breath plosives. The
transmitter includes an adjustable gain control to tailor the input to
the sound source. An integrated two-position power/mute switch
eliminates the need for a separate mute button. An RF power select
switch offers high and low settings. The transmitter operates on two
standard AA batteries and a battery condition indicator illuminates
when the batteries are good. An internal channel selector allows the
transmitter to operate on any one of ten channels. The transmitter is
constructed of high-impact materials and includes a heavy-duty
microphone stand clamp.
Architect’s and Engineer’s Specications
The frequency-agile FM wireless handheld transmitter utilizing a
cardioid dynamic element shall be part of a wireless system offered
in two UHF bands, 656.125–678.500 and 487.125–506.500 MHz.
The element shall be protected by a rugged metal head case with
integral two-stage pop lter. A two-position positive-action mechanical
power/mute switch operable without looking at the transmitter shall
