Using the Behringer FBQ2496 Feedback Destroyer PRO is quite straightforward. First, connect your audio equipment to the balanced inputs and servo - balanced outputs using the ¼'' TRS or gold - plated XLR connectors. You can choose between the auto mode, which continuously monitors the audio mix and sets the filters for you, or the single - shot mode that detects and eliminates feedback once and locks the filters until you reset them. In case of a sudden feedback emergency, just press the panic button. For easy operation, you can use the 'Set - and - forget' default setting. When it comes to maintenance, keep the device in a clean and dry place. Avoid exposing it to extreme temperatures or humidity. Also, check the power supply regularly to ensure it's within the 100 - 240 V~ range for optimal performance. You can use the MIDI implementation and user preset memories to quickly recall your favorite settings and make your audio setup even more convenient.
