A fully charged battery will last the entire school day. NOTE: Always turn the microphone off before charging. • If you are experiencing intermittent audio problems: • Check the batteries and replace them if necessary.
Integrated DSP Digital signal processing (DSP) is a specialized circuit that processes audio signals that have been converted to digital form. The VLR 102 Receiver has a built-in DSP that suppresses feedback while maximizing sound quality and intelligibility. As feedback occurs, up to 15 dynamic filters engage, automatically detecting and eliminating unwanted feedback frequencies.
a Input (In) port — If using a secondary receiver, connect a shielded twisted pair (STP) cable from this RJ-45 connector to the output port of the secondary device (consult your Extron sales representative for information on secondary receivers).
i Dome LED — Located in the center of the receiver dome, this LED indicates power, carrier detection, and relay status (see the following table). 9 Figure 21.
