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.
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.

CHANGING CARTRIDGES
The WL183, WL184, and WL185 microphones use interchangeable
cartridges. To remove the cartridge, unscrew the tip of the microphone
and remove it. Install the replacement cartridge by screwing it onto the
microphone base.
