About Audio-Technica ATW-2129CI

Before you delve into the world of professional audio, consider the Audio-Technica ATW-2129CI 2000 Series, a 10-channel frequency-agile UHF wireless system. This versatile system is designed to cater to a wide range of applications, from live performances and fixed installations to public addresses and A/V rental houses, even extending to places of worship.

This high-quality professional wireless system offers all the benefits you'd expect from a top-tier product, but at a highly competitive price. It boasts two available frequency bands and switchable antenna power for maximum flexibility. The system also supports the optional ATW-CHG2 two-bay recharging station, which can power up NiMH batteries in two ATW-T220a handheld transmitters and/or ATW-T210a UniPak transmitters in any combination.

The 2000 Series stands out with its 10 selectable channels in one of two UHF frequency ranges and True Diversity UHF wireless technology. It features automatic frequency scanning that, at the touch of a button, determines and sets the best available frequency. This ensures that any of the 10 channels can be used together without any frequency coordination problems or group selection issues.

The system also incorporates Audio-Technica's unique Tone Lock squelch and an easy-to-read LCD information display for user convenience.

Included in this package is the AT829CW Mini Cardioid Condenser Lavalier Microphone. This wireless clip-on/lavalier condenser microphone is designed with a cardioid polar pattern, making it ideal for professional business presentations, public speaking, and theater performances.

The AT829CW is designed to be worn on clothing, providing excellent yet unobtrusive sound pickup. Its wide-range capability ensures clean, accurate reproduction with high intelligibility for speakers, presenters, and performers. The microphone's cardioid polar pattern provides a 120-degree angle of acceptance.

The AT829CW comes with a 55" permanently attached miniature cable that terminates in a locking 4-pin connector for use with Audio-Technica UniPak body-pack transmitters. It also includes a clothing clip and a windscreen.

In summary, the AT829CW is an ideal choice for those seeking crisp, full-sounding voice pickup, excellent gain before feedback, suppression of background noise, and a rugged design for reliable performance. It is terminated for use with all Audio-Technica UniPak wireless systems, making it a versatile addition to any professional audio setup.
