L300 Two Channel Professional Power Amplifier
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.
