Introdução
The Radial Catapult MINI TX is a compact and robust 4-channel analog audio snake transmitter designed to send balanced audio signals over a standard Cat 5 or Cat 6 Ethernet cable. This device, when paired with a Catapult MINI RX unit (sold separately), provides a convenient and cost-effective solution for transmitting multiple audio channels over long distances, utilizing existing network infrastructure or dedicated Cat cable runs. Its passive design ensures high-fidelity audio transmission without the need for power.

Principais características
- Transmissão de áudio de 4 canais: Supports four balanced analog audio signals.
- Cat 5/6 Connectivity: Utilizes standard Ethernet cables for signal transmission, offering flexibility and cost savings.
- Operação passiva: Requires no external power, simplifying setup and increasing confiabilidade.
- Design compacto e durável: Housed in a rugged steel enclosure, suitable for professional use.
- XLR and RJ45 Connectors: Standardized connectors for easy integration into existing audio systems.
Instruções de configuração
Setting up the Catapult MINI TX is straightforward. Ensure you have a Catapult MINI RX unit and a shielded Cat 5 or Cat 6 Ethernet cable of appropriate length for your application.
- Identificar componentes: Locate the Catapult MINI TX (transmitter) and Catapult MINI RX (receiver) units. The TX unit typically has female XLR inputs, and the RX unit has male XLR outputs.
- Connect Audio Sources to TX: Connect your balanced audio sources (e.g., microphones, preamps, mixing console outputs) to the four female XLR inputs on the Catapult MINI TX unit. Each input corresponds to a specific channel.
- Conecte o cabo Ethernet: Connect one end of a shielded Cat 5 or Cat 6 Ethernet cable to the RJ45 connector on the Catapult MINI TX unit.
- Connect RX Unit: Connect the other end of the Ethernet cable to the RJ45 connector on the Catapult MINI RX unit.
- Connect Audio Destinations from RX: Connect the male XLR outputs of the Catapult MINI RX unit to your audio destinations (e.g., mixing console inputs, audio interface inputs, powered speakers).
- Verifique as conexões: Double-check all cable connections to ensure they are secure and correctly routed.

Instruções de operação
Once the Catapult MINI TX and RX units are connected, operation is automatic due to their passive design. No power or configuration is required.
- Fluxo de sinal: Audio signals from your sources connected to the TX unit's XLR inputs will be transmitted over the Cat 5/6 cable to the RX unit, and then output via its XLR connectors.
- Mapeamento de canais: Each XLR input on the TX unit corresponds directly to an XLR output on the RX unit. Ensure your audio sources and destinations are connected to the correct channels.
- Comprimento do cabo: While Cat 5/6 cables can transmit signals over significant distances, extremely long runs (e.g., hundreds of feet) may introduce slight signal degradation. Test your setup with the intended cable length to ensure optimal performance.
- Shielded Cable Requirement: Always use shielded Cat 5 or Cat 6 cable for reliable and noise-free operation. Unshielded cables may introduce interference.
Manutenção
The Radial Catapult MINI TX is designed for durability and requires minimal maintenance.
- Limpeza: Use um pano macio e seco para limpar a parte externa da unidade. Evite produtos de limpeza abrasivos ou solventes.
- Armazenar: Store the unit in a dry environment, away from extreme temperatures and direct sunlight, when not in use.
- Inspeção de cabos: Periodically inspect your Cat 5/6 and XLR cables for any signs of wear, damage, or corrosion. Replace damaged cables immediately.
- Cuidados com o conector: Keep the XLR and RJ45 connectors free of dust and debris.
