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 2002 SB internal amplifiers to
match an external XPA amplifier connected to the NetPA U 2002 SB line outputs:

2.
3.
4.
5.
6.
7.
Ensure the NetPA U 2002 SB outputs are properly connected to the XPA amplifier
inputs. Refer to the NetPA U 2002 SB User Guide and XPA User Guide found on
for more details on connecting the amplifiers.

Set the attenuation potentiometer on the XPA input to -10 dB (12 o'clock
position), as seen in the image to the right.
Open DSP Configurator and connect live to the NetPA U 2002 SB.
Double-click the Line Output ATT block (highlighted in yellow) to open the attenuator
dialog box, as shown below in figure 55.
