BW400H 400W RMS Professional Class-H Amplifier – Full-Range Power, Multiple Protections & Versatile Inputs

Model No.: RC-MA-001

The IRRICO RC-MA-001 (BW400H) is a professional 400W RMS Class-H amplifier delivering 500W full-range power at 4Ω load. Featuring multiple protection mechanisms (overload, overcurrent, short circuit, temperature control, and switch time delay), versatile combo XLR/TRS inputs, RCA/XLR line inputs, and analog XLR output with LED indicators. This reliable workhorse is perfect for sound reinforcement, PA systems, installed audio, and live sound applications.

Sufficient Power for Any Occasion – Delivers 400W RMS full-band (500W full-range) Class-H amplifier power with stable output at 4Ω load. Provides strong, reliable power for audio systems to meet sound amplification needs for a variety of occasions – from small venues to installed systems.

Comprehensive Protection Mechanisms – Features overload protection, overcurrent protection, short circuit protection, temperature control protection, plus switch time delay function. Effectively ensures stable and safe operation under different working conditions while extending the service life of the amplifier.

Rich & Flexible Input Interfaces – 2-channel balanced combo TRS/XLR interface for line/microphone input (with switching selector), plus 1-channel stereo RCA/XLR line-in interface. Easily connect different types of audio sources including microphones, line-output devices, mixers, and playback equipment to meet diverse usage scenarios.

Practical Output Interface – Equipped with analog XLR output interface for connecting to additional amplifiers, powered speakers, or recording devices. Enables daisy-chaining multiple amplifiers for expanded system coverage.

LED Status Indicators – Features power on and clipping indicator LEDs, allowing users to intuitively understand the working status of the device at a glance. Monitor signal levels and prevent distortion before it reaches your speakers.

Class-H Efficiency – Class-H amplifier topology provides high efficiency with reduced heat generation compared to traditional Class-AB designs. Lower power consumption, cooler operation, and reliable performance even under demanding conditions.

Professional-Grade Reliability – Built for continuous professional use in fixed installations, tour sound, and rental applications. The BW400H delivers consistent, clean power day after day.
