Product Overview

The Harmonai LD-350A is a professional-grade 8-channel power sequencer designed specifically for audio system power management. Built with high-quality 30A relays, it delivers a maximum total output power of 8000W — sufficient to drive 3–4 units of 1000W amplifiers. Its 8 controlled outputs feature independent 1-second delayed startup per channel, effectively preventing surge current damage during simultaneous power-on and extending equipment lifespan. A rear-panel AC voltage display enables real-time monitoring of supply voltage, while an integrated air circuit breaker provides comprehensive protection against leakage, short circuits, and overloads — ensuring full-spectrum power safety for your audio system.

Recommended Applications

The Harmonai LD-350A power sequencer is widely used in KTV venues, professional conference rooms, multi-function halls, and “Ying-K” (home cinema + karaoke) systems — anywhere centralized management of multiple audio devices is required. Independent per-channel control and sequential 1-second startup ensure orderly power-up of amplifiers, mixers, effects processors, and other gear, protecting sensitive audio equipment from damaging inrush currents. Its support for up to 10-unit cascading meets the complex power sequencing demands of large-scale live events and enterprise-level conferencing systems.
