Party Line Gain Adjustment with Zeus III
Unlike the Zeus III 4-wire channels that can have their input and output gain adjusted, the 2-wire channels (Channel A and
Channel B) can only have their input gains adjusted. This is because there is a limit on the amount of gain a 2-wire device can
receive (see “Specifications” on page 11), therefore a limiter between the 2-wire device and the Zeus III system limits the
amount of gain received by the 2-wire device.
The range for this field is -20dB to +20dB .
The default is 0.0dB .
To adjust the party line input gain , do the following:
1.
From the System menu in AZedit, select Gains .
A flyout menu appears .
2.
From the flyout menu, select Input/Output Gains .
The Input/Output Gains window appears .

column.
