General description
The SC14WAMDECT SF is a Cordless Audio Module
with an integrated baseband, radio transceiver, power
amplifier and crystal to be used in cordless microphone
applications in the DECT frequency band. This module
is intended for users with little or no DECT experience,
who wish to make a wireless audio system.
The module can be configured for various audio applications. A Public Address System has two portable
parts (PP) with two microphones and one fixed part
(FP) configured as a receiver and integrated into a
loudspeaker. Another application is a Tour Guide System where one a microphone (FP) broadcasts to up to
128 receivers (PP) with an integrated loudspeaker or a
headset connected. The SC14WAMDECT SF module
is suitable for both FP and PP usage: a hardware pin
selects the function of the module.
The SC14WAMDECT SF module is pre-approved for
use in all countries that use the DECT frequency band,
as well as the DECT 6.0 frequency band used in North
America.
