2.4WMS 400 The WMS 400 wireless microphone system comprises the SR 400 stationary diversity receiver, handheld transmitters HT 400/C with C 900 microphone element and HT 400/D with D 880 microphone element, and the PT 400 bodypack transmitter. The receiver and transmitters operate in a 30 MHz sub- band of each frequency set within the 650 MHz to 863 MHz UHF band. You can select the receiving fre- quency 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 select- ed on the receiver via infrared transmission.

2.5SR 400 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 RMU 400 rack mounting kit.

The display is protected from scratching by a transparent foil. You can peel the foil off at any time.
