Case
The side panel supports are removable for
mounting the receiver in a 19" rack.
C 417L
The C 417 L is one of the smallest lavalier microphones
available today and provides exceptional price/performan-
ce. With its wide frequency range and omnidirectional
pickup pattern with no proximity effect, the C 417L is an
ideal choice for announcers and presenters.
C 444 L
A flexible plastic behind-the-neck arch and large support
pads resting gently against the head keep the C 444 L
securely in place without pinching.
The flexible microphone arm absorbs mechanical impact
and places the microphone near the corner of the user's
mouth to prevent pop and breathing noise from being
picked up as it would if the mic were positioned right in
front of the mouth.
Avoiding feedback
As soon as an open mic gets into the coverage area of one
or more loudspeakers (left), it will pick up the speaker sig-
nal and recirculate it through the amps and speakers to
the point that the system starts whistling or howling at an
ear-splitting level. This is called feedback. The FOH spea-
kers are usually set up at the front edge of the stage and
it is relatively easy to stay behind an imaginary line bet-
ween the speakers (right). Presenters moving around on
stage should make sure never to point the microphone at
any of the speakers.
Alternative receivers
You can also use the PT 40 with the SR 40 diver-
sity receiver or the PR 40 portable receiver.
