3.2.1 Indicators 

 
The AV25-2 NET series has up to 4 rear panel LED indicators. The first 
is the power indicator which will illuminate when power is supplied to 
the amplifier. The second light is the signal present LED which will illu-
minate when signal is detected on either one of the input connection 
channels. The final 2 LED indicators (only on the NET+ models) are the 
“Clip” indicators, one for each channel. These lights will indicate that 
the input signal is too “hot” and will sound distorted when amplified. 
To fix this, the gain should be reduced at the preamp or mixer level.  

 

3.2.2 Controls (NET+ Models Only) 

 
All AV25-2 NET+ controls are located on the rear of the unit. There is 
no power switch so the AV25-2 NET+ will turn on whenever power is 
supplied to it.  
 
The rear panel contains two individual channel volume knobs . The am-
plifier is set to run off of a line-level source and the level should be ad-
justed for optimum performance. To adjust this knob, you will need a 
small flat-head screwdriver. While a  typical program source level is 
present, turn the rotary knob as far clockwise as you can without hear-
ing distortion or without the “Clip” indicator illuminating. If the signal is 
distorting and the knob is all the way counter-clockwise, adjust the gain 
down at the source level. 
 

3.2.3 Signal Priority Switching (NET+ Models Only) 
 

The AV25-2 NET+  amplifier includes selectable priority switching 
which allows either the network or local input to override the other in-
put depending on the switch setting. The switch position should be set 
to the priority input -- the signal that will interrupt the "normal" program. 
When audio is detected on that priority input the amplifier will mute the 
signal from the other ("normal") input. After an approximately 3.5 sec-
ond period with no signal on the priority channel, the "normal" signal 
will be un-muted.  For example, if a local microphone is to be used as a 
priority page, set the priority switch to "Local".  When a microphone 
signal is detected the "normal" network audio will be muted and the 
page will come through 
 
 

3.3 Dante 

 
If you have selected the Dante version of the AV25-2 NET series, con-
figuration is done using the Dante Controller software from Audinate. 
 

Dante Controller Software can be found on Audinate’s website at 

www.audinate.com

 

From there you can select Dante Controller under the Products section. 
This will require registration for Audinate’s portal and also includes ac-
cess to the Dante Controller User Manual which should be read for 
complete configuration instructions. 

 

3.3.1 Using Audinate’s Dante Controller  
 Software 

 
Once Dante Controller has been installed following the instructions in 
the Dante Controller Software User Manual (found at 

www.audinate.com

), launch the application to see the connection 

matrix. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Unlike CobraNet, Dante does not require IP configuration or bundle 
configuration. Instead, connections are made on the connection matrix 
shown above
