The KE Audio Multifunctional Amplifier Series (Four Channels) is crafted to support demanding commercial audio environments. Enclosed in a durable, cold-rolled steel 2U chassis, this unit is built to endure the physical demands of continuous, high-intensity operation typical in large venues.
At its core, the dynamic Class H amplification technology merges the sustained power delivery of a heavy-duty pure copper transformer with the precision of a Hi-Fi preamplifier. When operational, the system translates complex electrical signals into a clear and articulate sonic experience, minimizing distortion even at peak output levels. Listeners experience deep bass frequencies that remain distinct, complemented by clear mid-to-high notes that render spoken word and vocal performances with high clarity. This makes it highly suitable for applications where speech intelligibility and musical fidelity are equally important.
Whether driving the dynamic peaks of a live entertainment venue or maintaining the articulate nuances required in a corporate conference center, this amplifier delivers a transparent sound signature.
The internal layout is specifically designed to minimize cross-talk and electrical interference, preserving sonic details for professional sound engineering. The tactile feedback of the front-panel controls and the secure connection of the rear XLR connectors indicate a manufacturing focus on long-term operational stability, helping integrators reduce maintenance costs and system downtime.
This amplifier series is engineered to solve the most pressing challenges faced by audio integrators and venue operators, providing a seamless blend of power, protection, and acoustic purity.

For commercial audio integrators and large-scale sound reinforcement providers, power reserves and impedance matching are non-negotiable. This series is engineered to deliver relentless, stable power across a variety of demanding loads, ensuring your audio system never runs out of headroom during critical moments.
Tiered RMS Configurations: Available in four distinct power tiers—400W, 600W, 800W, and 1200W at 2/4Ω (RMS)—scaling up to a massive 800W per channel at 8Ω (RMS), providing exact matching for any loudspeaker array.
High-Current Transformer: Unlike standard switching supplies, the pure copper transformer guarantees continuous, sag-free voltage delivery, maintaining punchy, authoritative bass responses during prolonged high-output sessions.
Premium conference centers and high-end entertainment venues require an acoustic signature that is both powerful and impeccably clean. This amplifier is meticulously tuned to deliver a Hi-Fi listening experience at commercial sound pressure levels, ensuring complete audience immersion.
Audiophile-Grade Distortion Metrics: Boasting a Total Harmonic Distortion (THD+N) of less than 0.05% and Intermodulation Distortion below 0.3%, the amplifier ensures that complex vocal harmonies and intricate musical passages remain distinct and uncolored.
Crystal Clear Signal-to-Noise Ratio: With an SNR exceeding 100dB (A-weighted), the noise floor is virtually imperceptible, providing a deep, black sonic canvas for your audio.
Automated Noise Suppression: The intelligent background noise reduction system automatically clamps down on line noise, making it the perfect choice for highly sensitive vocal microphones in KTVs and corporate boardrooms.
Modern commercial installations require equipment that can adapt to specific audio routing requirements. This four-channel series acts as a versatile backbone for large-scale acoustic deployments.
Standardized Rack Integration: Housed in a standard 19-inch, 2U chassis (483mm × 88mm × 445mm), it integrates readily into existing equipment racks, maximizing spatial efficiency in AV control rooms.
Broad Venue Applicability: Tuned for the dynamic requirements of museums, theme parks, hotel banquet halls, fitness centers, and large-scale entertainment installations.
Commercial audio gear is often subjected to enclosed spaces and continuous vibration. The physical construction of this amplifier series reflects a focus on durability and thermal stability.
Substantial Physical Build: Weighing 21kg, the cold-rolled steel chassis and internal components are engineered to resist mechanical resonance and endure the rigors of fixed installations.
Intelligent Heat Dissipation: Features a variable-speed, thermally triggered cooling system that exhausts hot air from the chassis, ensuring the Class H3 rear amplification stages remain within optimal temperature ranges even under 2-ohm loads.
Reliable Component Selection: Internal components, from high-capacitance filter banks to secure XLR input/output sockets, are selected to support maximum longevity and signal integrity.
