Know before you buy
No, the Catapult Rack RX is a completely passive device. It does not require any external power, batteries, or phantom power to transmit your analog audio signals.
Yes, because the unit is passive and uses straight-through wiring, it will pass 48V phantom power from your preamp or console to your microphones without issue.
No, the Catapult Rack RX maintains a purely analog signal path. It uses Cat 5 or Cat 6 cables as a convenient, cost-effective transport medium rather than converting your audio to a digital format.
You can run standard Cat 5 or Cat 6 cables up to 100 meters (328 feet) while maintaining high signal integrity and a full 20Hz to 20kHz frequency response.
Yes, the Rack RX is designed to be compatible with other Radial Catapult stage boxes and modules. As long as the channel count and wiring configuration match, they will work together seamlessly.
No, this device is strictly for point-to-point analog audio transmission. You must connect the Cat cable directly between the Catapult units; plugging them into a network switch or router will not work and could potentially damage your equipment.
