3.2.2.10 High Gain WinTekHelp User Manual
.3.2.2.10 High Gain
If the applied audio input signal is at a lower level than the usual 0dBm level, the user can switch in a
20dB-gain pad in the audio circuit. By clicking on this button, this extra gain pad will switch-in when
this channel is selected and the exciter keys up. (Note that this has no effect if the microphone PTT is
keyed).
.3.2.2.11 Line Input
There are two transformer coupled audio Inputs, Line1, and Line 2. If these are enabled, then any audio
on one, is summed (mixed) with the other.
These two inputs can be set to apply Pre-Emphasis to the audio signals, or to have a Flat frequency
response, or to be disabled altogether (eg if one is running the audio through the external tone input
instead). This selection is made by clicking on one of the three “radio buttons” referred to as “Pre-
Emphasis”, “Flat”, or “Off”.
In the Advanced menu, each input can be separately configured. For example, Line 1 can be set to Pre-
Emphasis, and Line 2 to Flat or Off.
