Balancing Netpa Amplifier Output Level And Xpa Input Sensitivity - Extron electronics NetPA Ultra Series User Manual

Balancing NetPA Amplifier Output Level and XPA Input Sensitivity

Setting proper gain structure is necessary to ensure maximum audio clarity and amplifier
output performance. To properly balance the input sensitivity of XPA amplifiers, when used
in conjunction with NetPA Ultra Series amplifiers, follow the steps outlined below.
NOTE: When setting levels, pay attention to avoid digital clipping
The following is an example of how to adjust the NetPA U 1002/1004 internal amplifiers to
match an external XPA amplifier connected to the NetPA U 1002/1004 line outputs:

Ensure the NetPA U 1002/1004 outputs are properly connected to the XPA amplifier
inputs. Refer to the NetPA U 1002/1004 User Guide and XPA User Guide found on
www.extron.com for more details on connecting the amplifiers.
Set the attenuation potentiometer on the XPA input to -10 dB (12 o'clock position).
Open DSP Configurator and connect live to
the NetPA U 1002/1004.
Double-click the Line Output ATT block
(highlighted in yellow) to open the attenuation
dialog box (see the image on the right).
Set the Line Output attenuator(s) to -7 dB.
The attenuation value can be adjusted by
either dragging the fader (see figure 59,
or clicking in the display box (
manually entering the desired value.
