Application 1 – Mixer Channel Inserts
Use this configuration to independently protect two single microphones from feedback while leaving all other audio channels
unaffected. This application provides two independent channels of feedback suppression with up to 24 filters per microphone
channel.
Application Notes:
• Ensure all interconnecting equipment is turned off, including the amplifiers or powered speakers.
• Connect the mixer’s channel inserts to the AFS2.
• Apply power to the system. Ensure that the amplifiers or powered speakers are turned on last.
• Ensure the AFS2 is configured for dual mono (unlinked) operation, see ‘Linking/Unlinking Channels’ on page 18
for further information.
