Detailed Features/Benefits Description
3.3
Audio Quality Enhancement
3.3.1
Audio Processing Filter
The Audio Processing Filter (APF) is basically an audio high pass Þlter that can be programmed to
be either on or off using the CPS.
You will need to decide whether or not to activate the APF, depending upon the typical proÞle of the
receive audio on your individual customer's systems:
The default APF setting is "off". If the receive audio contains mainly low frequency components, APF
should be remain turned off for optimum audio clarity.
If the receive audio contains mainly high frequency components, APF should be turned on to
enhance the audio clarity.
3.3.2
X-Pandª Voice Compression
X-Pandª voice compression combines two audio quality enhancement features:
Companding :
Companding ensures more efÞcient communications by delivering clear audio that is easier to listen
to and understand. This feature saves time by reducing the need to repeat messages.
Companding is the term used to deÞne compressing the audio signal on transmission and
expanding the audio signal on reception. The overall effect is to reduce noise in the received signal,
providing crisper, clearer audio clarity.
Companding and Low Level Expansion (see below) are mutually exclusive; enabling one
automatically disables the other.
IMPORTANT:
Low Level Expansion (LLE):
Low Level Expansion cuts out the unwanted noise usually heard during pauses in conversations,
thus making communications easier to understand.
Low Level Expansion and Companding are mutually exclusive; enabling one automatically disables
the other.
Low Level Expansion is enabled by default (ie. the radios ship with LLE activated) and is
automatically disabled when Companding is selected in the CPS.
The X-Pandª technology also maximizes communication coverage by enabling low-level signals,
that would otherwise be "lost" amongst the background channel noise, to be heard.
TO BENEFIT FROM COMPANDING, ALL RADIOS ON THE SYSTEM
MUST HAVE THE FEATURE SWITCHED ON.
