H1S-800D 800W 1-Channel Class D Amplifier Module for Active Speakers

Product Overview

The H1S-800D is a compact 1-channel Class D plate amplifier module designed for active speakers, full-range loudspeakers, low-profile subwoofers, and line array speaker systems. It integrates a switch-mode power supply, Class D amplifier, and DSP control system into one lightweight plate amplifier structure.

Delivering 1 × 800W at 8Ω and 1 × 850W at 4Ω, the H1S-800D provides clean, stable, and efficient power for professional powered loudspeaker applications. Its compact chassis and low weight make it easy to install into different active speaker cabinets, especially where space-saving design is required.

The built-in DSP allows users to adjust key audio parameters including Mute, Polarity, Gain, Delay, Limiter, Mixer, EQ, and Crossover. DSP settings can be controlled through USB or RS-485, making system tuning convenient for speaker manufacturers, engineers, and professional audio users.

With high-efficiency Class D technology, multiple voltage options, and comprehensive protection circuits, the H1S-800D is a reliable amplifier solution for OEM/ODM active speaker projects, portable PA systems, fixed installations, and professional sound reinforcement applications.

Key Features

800W Single-Channel Output

The H1S-800D delivers:

• 1 × 800W at 8Ω
• 1 × 850W at 4Ω

It provides strong and stable output for active full-range speakers, compact subwoofers, and professional powered speaker systems.

Compact H1S Series Plate Design

The H1S series uses a smaller plate chassis compared with standard H1 series modules. Its compact size and lightweight structure make it easier to install into active speaker cabinets with limited rear-panel space.

Integrated DSP Control

The built-in DSP provides flexible sound tuning functions, including:

• Mute
• Polarity
• Gain
• Delay
• Limiter
• Mixer
• Equalizer
• Crossover

This allows precise system optimization for different speaker designs and acoustic environments.

USB and RS-485 Remote Control

The H1S-800D supports PC control through USB and RS-485 interfaces. Users can adjust DSP parameters, manage presets, and fine-tune system performance through software.

High-Efficiency Class D Technology

The Class D amplifier design provides high power output with low heat generation and reduced energy consumption. This helps improve long-term stability and makes the module suitable for continuous professional operation.
