You need to use a third party transmitter with the Catchbox Pro. We have tested for compliance the following transmitters: Shure ULX-D1 QLX-D1 UR1M Sennheiser SK 500 (Evolution Wireless) SK 300 (Evolution Wireless) SK 100 (Evolution Wireless) AKG DPT 700 PT 470 PT 420.
You could possibly use other transmitters as long as the belt-pack physically fits inside the Catchbox Pro and can be connected with any of the adapter cables that we provide with your unit: – 3 pin mini XLR (AKG) – 4 pin mini XLR (Shure) – 3.5 mm jack (Sennheiser).
If you are using a beltpack from another brand (even if it uses one of these connectors) please contact us and we will be happy to advise on compatibility.
