WL183, WL184, AND WL185 LAVALIER MICROPHONES
GENERAL
Models WL183, WL184 and WL185 are lavalier electret condenser
microphones designed for use with a wireless bodypack transmitter. Each
microphone has a 1.2 meter (4 ft.) cable terminated with a miniature
Switchcraft TA4F connector. The furnished tie clip can be rotated in 90°
intervals for placement flexibility.
APPLICATIONS
WL183 (Omnidirectional): Recommended for general purpose
sound reinforcement, recording, or remote monitoring applications.
Low handling noise. Pickup angle is 360°.
WL184 (Supercardioid): Recommended for sound reinforcement ap-
plications requiring high rejection of ambient noise and narrow pickup
angle. Use of windscreen highly recommended. Pickup angle is 115°.
WL185 (Cardioid): Recommended for general purpose sound rein-
forcement applications requiring good rejection of ambient noise. Use
of windscreen highly recommended. Pickup angle is 130°.
INSTALLATION
1. Insert the top of the microphone through tie clip loop from below until
tie clip loop snaps into place over the lower groove on the micro-
phone. Refer to the following illustration.
2. To install the snap–fit windscreen, press it down on the microphone
until it clicks into place inside the upper groove on the microphone.
The snap–fit windscreen provides 30 dB of pop protection.
NOTE: The snap–fit windscreen can be removed by spreading the
slot in the plastic snap–fit ring.
OR
To install the smaller foam windscreen, slip the windscreen over the
top of the microphone so that it covers the side slots.The foam wind-
screen provides 5 to 10 dB of pop protection.
