1.GENERAL

・ These specifications describe the preliminary specifications of “Receiver Board Module for DECT Microphone

System” for Audio Enhancement (AE).

2.FEATURES

・ Receiver Board Module has same features and outside interface as DECT Receiver （K-SRC14）.

・ System specifications and system functions including microphones are same as "DECT Microphone System"

with Receiver, so refer to “DECT Microphone System for Audio Enhancement Specifications”, with replace
"Receiver" to "Receiver board module.
