Hi Please advise below: The Shure ULXD4 systems come in a Quad and dual format. You are asking for QTY 22, is this total microphones? Lastly we would need to know what type of wireless you want for each as the Quad units will come with 4 Wireless Handheld microphones or 4 Lavalier Microphones, or 4 Headset Microphones. If you tell me you need a total of 22 handheld microphones total we would be looking at a quote consisting of 5 Quad units and 1 Dual unit all in the J50 wireless range which is the only range usable on military installations per Shure.
