Achieving the perfect equilibrium between power efficiency and acoustic fidelity is paramount for large-scale audio deployments. This amplifier utilizes a sophisticated Class TD architecture, seamlessly blending the best of both worlds to deliver an uncompromising auditory experience.
HIFI Preamplifier Integration: The front-end signal processing mirrors high-end audiophile equipment, ensuring the source material retains its original warmth and intricate detail.
Dynamic Class A Amplification: Provides the lightning-fast transient response and precise speaker cone control typically reserved for premium studio-grade Class A designs.
Nanocrystalline Advantage: The advanced switching power supply guarantees an ultra-stable voltage rail
Driving complex speaker arrays requires an amplifier that will not buckle under low impedance loads. This series is engineered to deliver relentless power, ensuring your audio system performs flawlessly regardless of the configuration or venue size.
Scalable Power Options: Available in six distinct power tiers, ranging from 800W to a massive 3200W (RMS) per channel at 2/4 ohms, allowing precise matching to your specific speaker requirements.
Extreme Low-Impedance Stability: Effortlessly handles 8-ohm loads, pushing out up to 2000W (RMS), making it ideal for daisy-chaining multiple subwoofers or line array modules.
Consistent Voltage Delivery: Maintains output voltage stability (ranging from 65V to 130V with <±5% variance), preventing power compression during peak performance hours.
In premium entertainment venues, audio clarity is the ultimate metric of success. This amplifier is meticulously tuned to deliver an uncolored, high-fidelity sound signature that satisfies the most discerning audio engineers and audiences alike.
Exceptional Signal-to-Noise Ratio: Boasting an SNR of over 100dB (A-weighted), it guarantees a pristine audio background, crucial for theatrical performances and quiet ambient spaces.
Ultra-Low Distortion Metrics: Keeps Total Harmonic Distortion (THD+N) below 0.05% and Intermodulation Distortion (IMD) under 0.3%, ensuring vocals and instruments remain crystal clear even at deafening volumes.
Equipment failure is not an option in live environments. We have integrated an exhaustive suite of digital protection mechanisms to ensure continuous, safe operation, protecting both the amplifier and the connected loudspeakers from unforeseen electrical anomalies.
Square Wave & Howling Defense: Instantly detects and mitigates harmful square waves and acoustic feedback, preventing catastrophic tweeter failure.
Thermal & Current Management: Intelligent heat dissipation systems work in tandem with overcurrent and overheating sensors to maintain optimal operating temperatures during 24/7 usage.
Space is a premium commodity in equipment rooms and touring racks. This four-channel powerhouse maximizes output density while maintaining a highly manageable physical footprint, streamlining logistics and installation for system integrators.
Compact 2U Form Factor: Fits seamlessly into standard 19-inch equipment racks, allowing integrators to pack immense power into a fraction of the typical space.
Optimized Weight Distribution: Weighing between 14kg and 16kg, it significantly reduces shipping costs and eases the physical burden on setup crews.
Versatile Venue Deployment: The perfect sonic engine for high-energy clubs, elegant hotel ballrooms, expansive theaters, restaurants, leisure centers, and demanding live touring rigs.
