The SoundTools CAT Box FX is a device designed to simplify stage wiring systems by offering a compact, reliable, and disconnectable solution for transmitting various audio and data signals over a single shielded CAT5e cable.
Function Description:
The primary function of the CAT Box FX is to convert and transmit up to four independent XLR lines (channels 1 through 4) over a single shielded CAT5e cable. This allows for the simultaneous transmission of different types of signals, including analog audio, AES3 digital audio, DMX lighting control, and intercom (COM) signals. By consolidating multiple cables into one, the CAT Box FX reduces cable clutter, simplifies setup and teardown, and enhances the overall efficiency of stage wiring.
The device features two etherCON connectors, labeled "IN/OUT" and "THRU." These connectors enable the daisy-chaining of multiple CAT Box units. This means that the same four channels can be extended to multiple locations, effectively allowing the CAT Box to function as a splitter. This capability is particularly useful in complex stage setups where signals need to be routed to various points without requiring separate long cable runs for each destination.
Important Technical Specifications:
- XLR Connectors: The CAT Box FX is equipped with four female XLR connectors. These are standard 3-pin XLR connectors, compatible with a wide range of professional audio and lighting equipment.
- CAT5e Connectivity: The device utilizes shielded CAT5e cable for signal transmission. Shielded CAT5e cable is crucial for minimizing noise and interference, especially when phantom power is being used. For certain applications, such as AES3, unshielded CAT5e cable can also be utilized, though shielded is generally recommended for optimal performance and interference rejection.
- etherCON Receptacles: The CAT Box FX incorporates etherCON receptacles, which are ruggedized RJ45 connectors designed for professional audio, video, and lighting applications. These connectors provide a secure and reliable connection for the CAT5e cable, preventing accidental disconnections during live performances or events.
- Signal Compatibility: The CAT Box FX is capable of transmitting a variety of signals, including:
- Analog Audio: Standard line-level or microphone-level analog audio signals.
- AES3: A professional digital audio interface standard.
- DMX: Digital Multiplex, a standard for digital communication networks that are commonly used to control stage lighting and effects.
- COM: Intercom signals, typically used for communication between production crew members.
- Phantom Power Compatibility: The use of shielded CAT5e cable is required when phantom power is being transmitted through the CAT Box FX. This ensures that the phantom power supply remains stable and free from interference, which is essential for the proper operation of condenser microphones and other phantom-powered devices.
Usage Features:
- Simplified Wiring: The most significant usage feature is the simplification of stage wiring. Instead of running four individual XLR cables, only one CAT5e cable is needed, reducing setup time, cable management complexity, and potential tripping hazards.
- Daisy-Chaining Capability: The "IN/OUT" and "THRU" etherCON connectors allow for easy daisy-chaining of multiple CAT Box units. This means that a single CAT5e cable run can feed multiple CAT Boxes, distributing the same four channels to various locations on stage or in a venue. This acts as a built-in splitter function, eliminating the need for external signal splitters for these four channels.
- Versatile Signal Transmission: The ability to transmit analog audio, AES3, DMX, and COM signals simultaneously over a single cable makes the CAT Box FX highly versatile for various production needs, from live music concerts to theatrical performances and corporate events.
- Robust Construction: The device is designed for the rigors of professional use, featuring a durable metal housing that can withstand the demands of touring and frequent setup/teardown.
- Compact Design: Its compact form factor makes it easy to integrate into existing stage setups without taking up excessive space.
Maintenance Features:
- Chassis Ground Switch: Located on one end of the CAT Box FX, a chassis ground switch provides a crucial maintenance and troubleshooting feature. This ground lift switch disconnects the cable shield from the chassis of the box. This is particularly useful in situations where the metal housing of the CAT Box might come into contact with other grounded equipment or surfaces, potentially causing ground loops or interference. By lifting the ground, such noise can often be eliminated, ensuring a cleaner signal. This feature allows technicians to quickly address hums or buzzes that might arise from grounding issues without needing to reconfigure the entire system.
- Durable Connectors: The use of etherCON and professional-grade XLR connectors ensures long-term reliability and reduces the need for frequent connector replacement. These connectors are designed for repeated mating cycles and provide secure connections, minimizing wear and tear.
- Shielded Cable Requirement: While not a maintenance feature of the box itself, the emphasis on using shielded CAT5e cable contributes to the system's overall reliability and reduces the likelihood of signal degradation or interference that would otherwise require troubleshooting. Using the correct cable type is a preventative measure that minimizes future maintenance needs related to signal quality.
