Application 4 – In-line Between Mixer & Amp
This application is ideal for dedicated feedback suppression on the entire mix, when your mixer does not
have master insert connections. This application provides two channels of feedback suppression with up
to 24 filters per channel. If your mixer does have master insert connections, it is recommended that you
connect the AFS 224 to these master insert jacks as described in Application 3.
1. Turn off the power to the mixer and amplifiers.
2. Ensure the AFS 224 is configured for stereo linked operation. See “Linking Channels” for further
information.
3. Connect the master outputs of the mixer to the inputs of the AFS 224.
4. Connect the outputs of the AFS 224 to the power amp’s inputs, or active crossover if using one.
5. Apply power to the mixer and amplifiers.
