AKG WMS UHF 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.

C 417 L

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 417 L is an ideal choice for announcers and presenters.

Antenna

The swiveling antenna is mounted on the front panel, allowing the receiver to be rack mounted.

Case

The side panel supports are removable for mounting the receiver in a 19" rack.

Alternative receivers

You can also use the PT 40 with the SR 40 diver- sity receiver or the PR 40 portable receiver.

ON/OFF switch

with status LED.

RF LED

Illuminates to indicate that RF signal is being received. If the RF signal fails or the squelch comes on, the MUTE LED will be lit.

SR 40 Receiver

Frequency color code platelet

Receivers using the same frequen- cy are marked with the same color code.

Volume

Matches the output level of the receiver to the input gain of the mixer. (For details refer to page 27).

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.
