1. To adjust the level for a cross point, right-click on the cross point and select Cross Point from the
shortcut menu. The Cross Point Attenuation Slider appears.
2. Move the slider or use the selector box to set the Gain/Attenuation level in dB. The range is from -60 to
12dB in .5dB increments. The default is 0dB.
» NOTE: The changes are made in real time.

The INTERACT Pro allows the user to set up to two Virtual References.
Virtual Acoustic Echo Cancellation (AEC) References allow you to combine multiple audio sources to
create a single echo cancellation reference, such as video conferencing and teleconferencing combined. In
these and some other applications, using virtual AEC references improves AEC performance.
The two virtual references are shown on the far right side of the Matrix.:
Use virtual references when your output to the amplifier contains audio not wanted in the AEC Reference,
such as local microphones. Route the inputs that contain audio that needs to be canceled, like “receive
from telco” or video codecs, (etc.) to your virtual reference(s). This gives you the capability to reinforce local
microphones into the room and not have them included in your reference.
» NOTE: If the channels selected for a virtual reference use Processing or Faders, you should
select the processing or fader channel as the virtual reference source. This provides the AEC
process with the most accurate reference for the signal, thereby providing faster convergence
and more accurate AEC performance.
When using virtual references, you must assign an output to that virtual reference in order to track audio level
changes. This output will typically be the output feeding your local room amplifier. If this is not done correctly,
echo may be heard at the far end when level changes are made.
