Application 2 - Mixer Subgroup (Bus) Inserts - dbx AFS2 Owner's Manual

Application 2 – Mixer Subgroup (Bus) Inserts
Use this configuration to protect two independent groups of microphones from feedback while leaving all other audio channels
unaffected. For example, feedback suppression could be applied to certain instruments which require feedback suppression
(e.g., drum mics, vocal mics, etc.) while keeping instruments that desire feedback (such as loud guitar cabinets in a rock band)
separated. This application provides two 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 subgroup 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 if processing two independent subgroups. If processing
a stereo subgroup, the AFS2 should be configured for stereo (linked) operation. See 'Linking/Unlinking Channels' on
page 18 for further information on this configuration option.
