The Filter drop-down lists let you select an audio filter for each enabled receive
path.
Option Description
Flat full band Passes audio evenly across the audio spectrum.
Flat speech Passes only speech frequencies.
band
De-emph Passes audio in the speech range, attenuating higher
speech band frequencies. This option can be used if the base station will
receive pre-emphasised transmissions.
De-emph full Passes all audio, attenuating higher frequencies.This option
band can be used if the base station will receive pre-emphasised
transmissions.
Subaudible Passes only the subaudible band, containing any CTCSS tones
band or DCS codes. This option can be used to separate out the
signalling and put it on the line output that is connected to a
tone panel.
Enables the audio path from the receiver to balanced audio output, using the
filter selected for Path A.
Enables the audio path from the receiver to unbalanced audio output, using the
filter selected for Path B.
The Line level boxes on the receive path set the audio level at the line output
pins. When the reciter receives a signal that is modulated to 60% of a maximum
transmit deviation that is equivalent to the receiver setting, it outputs audio on
the line at the level you set. For channels using the default profile, the receiver
setting is determined by the channel spacing (see
page 119). For channels using custom profiles, it is defined by the Receiver
channel box (see "Receiver channel" on page
