Features and Controls

The Audio-Technica PRO 88W wireless microphone system is compact, lightweight and compatible with nearly all video camcorders. The PRO 88W operates in an authorized VHF band and has a useful range of up to 300 feet in line-of-sight applications.

Each PRO 88W system operates on two crystal-controlled, switch-selectable frequencies for clear, clean transmission. There are 4 pairs of frequencies available:

Freq. Code	“A” Channel		“B” Channel
T13	T1: 169.445 MHz		T3:	170.245 MHz
T24	T2: 169.505	MHz	T4:	170.305 MHz
T57	T5: 171.045	MHz	T7:	171.845 MHz
T68	T6: 171.105	MHz	T8:	171.905 MHz
TVHF	Ch. 7: 179.400	MHz	Ch. 8:	180.600 MHz

The Frequency Code appears on the back of each unit. Both transmitter and receiver must have the same Frequency Code, and both units must be set to either “A”

or “B.” TVHF frequencies are in television channel bands 7 and 8. Use whichever channel does not have an operating TV station in your area.

Note that two transmitters on the same frequency will not work with one receiver.

The PRO 88W is offered with a choice of cardioid or omnidirectional clip-on microphones. Each type offers distinct benefits: cardioid microphones reduce room noise and allow a greater working distance than omnidirectional microphones; omnidirectional microphones are less susceptible to wind and clothing noise and provide extended frequency response.

Cardioid PRO 88W System

PRO 88W-829 includes AT829mW miniature cardioid clip-on microphone.

Omnidirectional PRO88W Systems

PRO 88W-830 includes MT830mW subminiature omnidirectional clip-on microphone. PRO 88W-R35 includes ATR3350mW miniature omnidirectional clip-on microphone.

Before use, make certain you understand the function and operation of the system.

RF Interference

Please note that wireless frequencies are shared with other radio services. According to Federal Communications Commission regulations, “Wireless microphone operations are unprotected from interference from other licensed operations in

the band. If any interference is received by any Government or non-Government operation, the wireless microphone must cease operation...”

If you need assistance with operation or frequency selection, please contact an Audio-Technica dealer.
