Frequently Asked Questions
Does the TX4M require a matching Radial receiver unit, or can it connect to standard network switches?
The TX4M requires a compatible Radial Catapult receiver unit on the far end — it is not compatible with standard IT network switches. The Neutrik Ethercon outputs carry analog or AES audio-over-Cat5, not Ethernet data packets.
Does the TX4M supply phantom power to condenser microphones on its XLR inputs?
The TX4M passes phantom power through from your console or preamp — it does not generate 48V internally. Your source device must supply phantom power on each channel where condenser mics are connected.
Can the TX4M carry AES digital audio alongside analog signals on the same unit?
Yes. The TX4M is protocol-agnostic — the same XLR inputs and twisted-pair transmission handle both analog balanced audio and AES digital sources. You can mix signal types across channels depending on your system requirements.
What does the ground lift on the TX4M actually address in a live environment?
The ground lift is specifically provided for the Ethercon cable connection to break ground loops that form when the audio snake shares physical infrastructure with other grounded systems in a venue. It does not affect the XLR input grounds.
What are the XLR thru-puts on the TX4M used for?
The XLR thru-puts duplicate each channel's signal at the stage box, allowing local monitoring feeds, amp rack connections, or redundant recording splits without additional DI boxes or signal splitters downstream.
