The L300 Two Channel Power Amplifier is a professional Class AB transformer amplifier designed for reliable power delivery in stage sound systems, commercial audio installations and professional PA applications.
Featuring 2 channels of 300W output at 8Ω, 400W output at 4Ω, and 575W bridged output at 8Ω, the L300 provides flexible system configuration for different loudspeaker requirements.
With excellent electrical performance, including a high damping factor (>280), low total harmonic distortion (≤0.05%), and a high signal-to-noise ratio (≥98dB), the amplifier delivers clean, stable and accurate audio reproduction.
The compact 2U rack-mount design makes the L300 easy to integrate into professional sound racks together with PA speakers, stage monitors, line array systems and other audio equipment.

The L300 uses a professional Class AB amplifier circuit, providing a good balance between sound quality, efficiency and reliability.
It delivers:
Low distortion audio output
Smooth frequency response
Stable long-term operation
Reliable performance for professional sound reinforcement
The amplifier supports multiple connection modes:
2 × 300W @ 8Ω Stereo
2 × 400W @ 4Ω Stereo
575W @ 8Ω Bridge Mode
This flexibility allows the L300 to match different speaker configurations and system designs.
With a damping factor greater than 280, the L300 provides strong control over connected loudspeakers, especially in low-frequency reproduction.
This helps improve:
Bass response
Speaker stability
Transient accuracy
Overall sound clarity
The standard 2U rack-mount design allows easy integration into professional audio equipment racks.
It is suitable for:
Stage sound systems
Conference audio systems
Churches
Schools
Hotels
Small and medium performance venues
Rental audio systems
