Audio Technica 3000 Series ATW 3141B UHF Wireless Handheld Mic System

$811.00 $699.00

The dynamic capsule features a cardioid polar pattern, which is effective in minimizing noise and ambiance at the off-axis sections of the microphone. RF output is switchable between 30 mW and 10 mW enabling high output in greater distances.

Audio-Technica’s third-generation 3000 Series wireless systems offer up to 1001 selectable UHF frequencies and new features for clear sound & intuitive operation. AT has simplified selection of usable frequencies, increased system reliability, and illuminated transmitter screens for clear reads on dark stages. It all adds up to the luxury of rock-solid, richly detailed high-fidelity sound.

The ATW-T341b cardioid dynamic wireless handheld transmitter features the Artist Elite® AE4100 cardioid capsule created for live sound venues.  The element includes internal shock mounts for low handling noise.  An integral two-stage pop filter within the rugged steel headcase protects against “p” pops and other breath plosives.  Transmitter setup functions are menu-driven via soft-touch controls.  To prevent accidental changes, the controls are covered by the transmitter’s handle case when not being used.

Operating using two standard AA batteries, the transmitter features high- and low-level RF output settings.  The low-level setting allows two additional hours of battery life while retaining a strong RF signal link.  Soft-touch controls provide convenient access to a variety of functions including RF power, audio input level, power/mute locks and frequency selection.  Each transmitter’s backlit LCD display presents a great deal of setup and operating information clearly and conveniently including battery fuel remaining, mute, and operating frequency.  A flashing “Lo-Batt” alert visually signals the battery life almost depleted.  Programmable power/mute locks limit the functioning of transmitter’s power/mute button as desired for particular users and applications.  A dual-colour status LED illuminates green when power is on, and red when the transmitter is muted.  To match the audio input level to the transmitter, a four-position audio input gain setting selected through the function menu is provided.  The transmitter housing is made of metal with an integral antenna.  Each handheld transmitter includes a heavy-duty Quiet-Flex™ stand clamp.
