2.4 WMS 450

The WMS 450 wireless microphone system comprises the SR 450 stationary diversity receiver,
handheld transmitters HT 450/C with C 5 microphone element and HT 450/D with D 5 microphone ele-
ment, and the PT 450 bodypack transmitter. The receiver and transmitters operate in a 30 MHz subband
of each frequency set within the 650 MHz to 865 MHz UHF band. You can select the receiving frequen-
cy from the preprogrammed frequency groups and subchannels of your receiver or set it directly in 25
MHz-increments. Both the handheld and the bodypack transmitter are set to the parameters selected on
the receiver via infrared transmission.

2.5 SR 450 Receiver

The receiver provides two operating modes:
In LOCK mode, all setup functions are electronically locked to prevent parameters from being readjust-
ed unintentionally during a performance or lecture. The "LOCK" label on the display indicates the receiv-
er is in LOCK mode.
SETUP mode allows you to adjust and save all receiver parameters. In SETUP mode, the "LOCK" label
disappears. An infrared transmission link tunes the handheld or bodypack transmitter to the same fre-
quency as the one you selected on the receiver. You can also set the handheld transmitter audio input
gain on the receiver and transmit the setting to the transmitter via infrared.
You can use the receiver as a standalone unit or install it in a 19" rack using the supplied Rack Mount
Kit.
The display is protected from scratching by a transparent foil. You can peel the foil off at any time.
1 POWER: Switches power to the unit on or off.
