Description
The SR20TGX-US is a 10U preconfigured amplifier system rack designed for touring and professional live sound applications. It ships populated with three TGX20 DSP amplifiers and integrated power distribution to deliver multichannel amplification in a compact footprint. The system includes redundant networking and user-configurable I/O to support complex signal routing and reliable operation.
Key features include two independent managed network switches for network redundancy and glitch-free audio distribution – integrated sliding rack doors – and reversible mounting for the power distribution assembly. The rack is stackable and lockable to scale output and maintain a consistent footprint for transport and stage placement. Customizable I/O options allow matching system connectivity to the installed audio infrastructure.
Internally the rack provides 12 amplifier channels and three pairs of NL8 outputs to feed multiple speaker systems. Balanced line-level inputs and AES3 digital I/O are provided on Neutrik XLR connectors while the network uses etherCON RJ45 connectors. The preconfigured managed GB Layer-3 switches support OMNEO/Dante workflows and enable deterministic networked audio performance.
Connectivity is comprehensive and purpose-built for pro audio rigs – inputs include balanced analog and AES3 digital options and outputs use NL8 speakON connectors for high-current loudspeaker feeds. Two RJ45 etherCON ports per switch provide primary and secondary network topology options for redundancy and large-signal distribution. Power inlet options include EU CEE 32A 3-phase and US NEMA L21-30 208 VAC to match regional power systems.
This system rack suits rental companies, touring engineers, and fixed-install venues that need high channel density and simplified deployment. It is engineered to be stacked on a single dolly and locked together to scale total system power up to the equivalent of large multi-rack amplifier arrays. The integrated sliding doors and rugged chassis speed rigging and protect equipment during transport and operation.
Installation is straightforward thanks to the prepopulated amplifiers, reversible PDU mounting, and clearly labeled I/O panels – reducing setup time and onsite configuration. The TGX system rack is built for road use with touring-grade hardware and a design that prioritizes serviceability and networked audio integration. Ambient operating limits and payload ratings are specified to ensure reliable field performance.
