The TX SR-728 is a 10-outlet AC power sequencer and conditioner housed in a standard 1U rack-mount chassis, used to start up and shut down a stack of audio, video and lighting equipment in a controlle
Ten rear or front-panel AC outlets switch on and off in sequence with a short delay between channels.
A digital voltage readout sits on the front fascia alongside a master power switch and individual arming switches for each outlet group.
Amplifiers and high-inrush gear start up last and shut down first to protect speakers and mixers from thumps.
The unit includes surge protection on the mains input and accepts 110V or 220V feeds through a thermal or magnetic circuit breaker.
At weddings, conferences and stage shows across Sri Lanka, the SR-728 lives in a flight case with amplifiers, mixers, wireless receivers, video switchers and lighting controllers.
One front switch arms the whole rack, sequencing each outlet so the venue breaker does not trip from combined inrush current.
The voltage display lets you confirm clean generator power before running sensitive audio and video equipment.
Why Choose This Product
- Externally Powered: Includes a power adapter - needed for active signal boost and longer cable runs.
- Sequential switching: Outlets energise in timed stages so amplifiers and lighting power up after low-level gear, preventing speaker thumps and breaker trips.
- Voltage readout: Front-panel digital display shows incoming mains voltage in real time, useful for checking generator feeds at outdoor events.
- Rack-mount surge protection: 1U steel chassis fits a standard 19-inch rack and includes mains surge suppression for the full outlet bank.
- Front USB outlet: Auxiliary USB port on the front panel lets the operator charge a phone or tablet from the rack without opening a separate adapter.
How Can You Use This
- Laptop to Projector / Display: Connect a laptop or DSLR to a projector, TV, or external monitor at events, classrooms, and meeting rooms.
- Audio Routing for Events: XLR / 6.35mm / 3.5mm cables connect microphones to mixers, mixers to speakers, and instruments to amplifiers.
- Multi-Screen Signage: HDMI splitters duplicate one source across multiple displays for video walls, lobby signage, and trade-show booths.
- Camera-to-Recorder / Monitor: HDMI / SDI / USB cables connect cameras to external monitors, recorders, and live-stream encoders.
