224
Application 2 – Mixer Subgroup Inserts
This setup is ideal for applications that require feedback suppression on certain instruments (such as
microphones) while keeping instruments that desire feedback (such as guitars) separated. This application
provides two channels of feedback suppression with up to 24 filters per channel.
1. Turn off the power to the mixer and amplifiers.
2. Ensure the AFS 224 is configured for dual mono operation if processing two independent
subgroups (this is the default configuration). If processing subgroups containing stereo material,
the AFS 224 should be configured for stereo linked operation. See “Linking Channels” for further
information.
3. Connect the mixer’s subgroup insert sends to the inputs of the AFS 224.
4. Connect the outputs of the AFS 224 to the mixer’s subgroup insert returns.
5. Apply power to the mixer and amplifiers.
