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.

Operation
Power Source
The transmitter and receiver are each operated by a 9V alkaline battery. Before use,
install a battery as shown. Make certain the battery is fully seated in its compartment
so the cover slides in place easily. Battery life with alkaline batteries is approximately
8 hours of operating time. The receiver also features an external jack for connecting a
9V DC power supply (not included).

Note: To avoid possible damage due to leakage, the batteries should be removed if
the PRO 88W will not be used for a long time.
Transmitter Operation
Each unit provides two selectable transmitting frequencies.
1) Switch the Channel Selector Switch to the desired channel (A or B).
2) The belt clip on the back of the unit clips the transmitter onto a belt, or the
transmitter simply can be put into a pocket.
3) Plug the microphone into the Mic Input Jack.
4) The microphone can be clipped to a necktie or other clothing, using the supplied
clothing clip.
5) Slide the power ON/OFF switch to the ON position (the LED indicator will light).

Receiver Operation
Each unit provides two selectable receiving frequencies.
1) Switch the Channel Selector Switch to the same channel as the one selected on
the transmitter (A or B).
2) Attach the receiver to the video camcorder by inserting the mounting bracket
foot into the camcorder’s accessory shoe.
3) Connect the mini-plug audio signal cable from the Mic Out jack on the receiver
to the external mic jack on the camcorder.
4) Attach the monitor earphone to the Phone Out jack on the receiver to listen to
the signal.
5) Turn the Power ON/OFF switch to the ON position (the LED indicator will light).
Helpful Hints
• If the selected channel is noisy, switch both the transmitter and receiver to the
other channel.
• If there is a “dead spot” in a room (indicated by noise on the external earphone),
try a slight change of position or try changing frequencies.
• Low ceiling fluorescent lighting, overhead telephone lines or close proximity to
metal fences can all cause static. If this occurs, try a slight change of position
and/or try changing frequencies.
• When the battery voltage drops below 6V, the LED indicator will go out. This
means you need a new battery.
• Turn off the power whenever the units are not in use. Remove the batteries if
the units will be out of service for a long time.
NOTE: There are no user-adjustable parts inside the transmitter or receiver. Do not
attempt to open or make any adjustments.

Mounting
Belt Clip
A detachable belt clip is included for convenience. Slide the tapered end of the belt
clip into the grooved area located on the back of the unit until it clicks into place.

Mounting on a Camera
The receiver can be mounted to a video camcorder by means of the supplied
mounting bracket. Insert the “head” end of the bracket into the grooved area on
the back of the receiver and then insert the “foot” end to the mounting shoe of the
video camcorder.
You can also attach the receiver to the camcorder by using the included Velcro
tape. Remove the belt clip from the back of the receiver. Without separating the two
halves of the Velcro, remove the protective paper from the “hook” half of the Velcro
and press the exposed adhesive side against the back of the receiver. (Do not place
it over the Frequency Code on the nameplate, or the battery compartment cover.)
Then, without removing the protective paper from the other side, hold the receiver-
plus-Velcro against the camcorder to find a position with a sufficiently flat area that
does not interfere with the camcorder viewfinder, controls or hinge points.
Once you are satisfied with the position, remove the remaining protective paper
and press the “pile” half of the Velcro into place on the camcorder.
The double-sided adhesive foam provided is only for permanent mounting of
the receiver.
