I want to connect Feedback destroyer(Behringer DSP1124P) to the 24Channel mixer in order to eliminate feedbacks on all mics (6 in all).I am not using any compressor. The mixer image below is a replica of my own except that mine has 24 channels. Each channel on the mixer has MIC IN(XLR), LINE IN(1/4-inch TRS), INSERT IN(1/4-inch TRS). It also have GROUP OUT 1 & 2, AUX SEND 1 & RETURN 1, AUX SEND 2 & RETURN 2 (all 1/4-inch TRS). The mics are currently connected to the MIC IN on Channels 1-6. Please advise on how best to connect the equipment to achieve my objective. Also required is your opinion on the cabling indicating type of connectors e.g. balanced cables. Thank you.
