1.0Introduction
This chapter describes those radio features and functionality which offer a significant benefit to your customers. The intention is to provide you with useful information which is relevant to your customers that will help you sell the GP300 Series Professional portable radios.
2.0Audio Quality Enhancement
2.1Xpand™ Voice Compression
Xpand™voice compression combines two audio quality enhancement features - Companding and Low level Expansion (LLE).
2.1.1Companding Feature
Companding is a collective term to define compressing the audio signal on transmission and
expanding the audio signal on reception. The overall effect is to reduce noise in the received signal, giving you crisper, clearer audio clarity. Companding should only be used when other radios in your system have the same companding feature available.
Companding and LLE are mutually exclusive, switching on one of the features automatically switches off the other.
It is important to ensure that all radios in a team have the feature switched on.
Benefits
Crystal clear communication which makes listening easier.
Improves efficiency as messages are heard and understood first time.
2.1.2Low Level Expansion (LLE)
Feature
This allows improvements in audio quality by reducing noise usually heard during pauses in conversation.
This feature is automatically included in every radio and should only be switched off in specialised applications.
Benefit
Pauses in conversations are now silent which makes it easier to listen.
