Using the Behringer FBQ1000 is a breeze. First, connect it to your sound system using the balanced inputs and servo - balanced outputs with the provided TRS and gold - plated XLR connectors. For quick feedback suppression, you can use the 'Set - and - forget' default setting. If you want the device to continuously monitor the mix, switch to Auto mode. In Single - Shot mode, it will detect and destroy feedback and lock the filter until you reset it. Manual mode gives you full control to set up to 24 filters. When it comes to maintenance, keep it in a clean and dry place. Avoid exposing it to extreme temperatures or humidity. If you need to recall a specific setting, use the MIDI implementation and user preset memories. Remember, this device is designed to protect your ears, so use it properly when using in - ear monitors.
