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.
