The AS1500 Professional Power Amplifier is a high-performance 2-channel solution engineered for demanding speaker systems, leveraging advanced three-stage Class H technology for exceptional efficiency and power. Housed in a 3U rack-mount chassis (482x545x130mm), it delivers 2x1500W @8Ω and 2x2250W @4Ω in stereo mode, plus 4500W @8Ω and 6700W @4Ω in bridged mono—making it ideal for large PA systems, subwoofer arrays, and touring setups. Unlike standard Class H amplifiers, its three-stage power supply boosts efficiency by 40% compared to conventional designs, while improving thermal dissipation by 60% and dynamic headroom by 30%. With global voltage compatibility (110V/220V/230V) and professional-grade protection, the AS1500 excels in both fixed installations and road use.

• 40% higher efficiency: The three-stage design adjusts power supply voltage in three increments (instead of two) based on audio signal levels, reducing energy waste and heat generation. This lowers operating costs and extends component life (critical for 24/7 installations).
• 60% improved thermal dissipation: Reduced heat output means the amplifier runs cooler, even during continuous high-power operation—ideal for touring rigs or installations with limited airflow (e.g., enclosed equipment racks).
• 30% greater dynamic headroom: Extra headroom handles sudden audio peaks (e.g., drum crashes, vocal crescendos) without clipping, ensuring clean sound even in dynamic music genres (e.g., rock, jazz).
• Ultra-low <0.05% THD+N (20Hz-20kHz) ensures distortion-free sound, suitable for high-fidelity applications like orchestral performances or studio monitoring.
• >80dB channel separation prevents cross-talk, keeping audio isolated between left/right channels or main/subwoofer setups (e.g., avoiding bass bleed into vocal channels).
• Intelligent thermal management: A combination of large heat sinks and temperature-controlled fans maintains optimal temperature, with auto-recovery if overheating occurs (no manual reset needed).
• Rugged 3U chassis: Built with heavy-duty aluminum to withstand touring shocks and vibrations, plus corrosion-resistant finishes for long-term durability in outdoor or humid environments.
• Matches high-power speakers: Ideal for large-format 2-way/3-way passive speakers (1200-1800W program), dual 18"-21" subwoofers (1500-2500W program), and full-range line arrays (1000-1600W continuous).
• Stable 2Ω performance: Handles low-impedance loads (common in multi-speaker setups, e.g., 4x8Ω speakers daisy-chained per channel) without power loss or overheating, expanding system design options.
• Versatile bridged mode: 4500W @8Ω bridged output drives single high-power speakers (e.g., large subwoofers, line array modules) or centralized PA systems for stadiums.
• Concert venues (2,000-5,000 capacity): Powers line arrays with 2x2250W @4Ω stereo output, ensuring uniform sound coverage across the venue.
• Stadiums & arenas: Used in bridged mode (6700W @4Ω) to drive multiple subwoofers, delivering deep bass that reaches every seat (e.g., football stadiums, indoor arenas).
• Outdoor festivals: Withstands harsh conditions (when paired with weatherproof speakers) and provides consistent power for all-day events (e.g., music festivals, outdoor concerts).
• Stage wedges (large theaters): Drives 15"-18" high-power stage monitors (1000-1600W program), giving musicians clear foldback audio even in loud performance environments.
• Fixed theater sound systems: Powers main speakers in large auditoriums and theaters, with low distortion preserving speech intelligibility (e.g., plays, musicals) and music quality (e.g., live orchestras).
• Outdoor amphitheaters: Supports weather-resistant speaker systems in parks or open-air venues, with rugged build handling temperature fluctuations and moisture.
• Column array systems (lecture halls): Drives large column speakers (1200-1800W continuous) for uniform sound coverage in long, narrow venues (e.g., university lecture halls, conference centers).
• Front-fill/delay arrays (concert halls): Enhances sound for front-row audiences or distant seating areas, using stereo mode to maintain audio balance (e.g., symphony halls, opera houses).
• Distributed stadium systems: Powers multiple speaker zones in stadiums (e.g., concourses, luxury boxes), with stable 2Ω performance supporting multi-speaker setups per zone.
Standard Class H amplifiers use a two-stage power supply (low and high voltage) to adjust to signal levels, while three-stage Class H adds a middle voltage tier. This finer adjustment reduces “voltage switching” distortion (a common issue in two-stage designs) and improves efficiency by 40%. For users, this means cleaner sound (no distortion during voltage transitions), less heat (reducing fan noise), and lower energy costs—especially in long-running installations or high-power setups.
Yes. Most dual 18" subwoofers have a program power rating of 1500-2500W and an impedance of 4Ω or 8Ω. The AS1500’s 2x2250W @4Ω stereo output can power one dual 18" subwoofer per channel (ideal for stereo bass in concert halls), while its 4500W @8Ω bridged mode can drive a single high-power dual 18" subwoofer (e.g., centralized bass in stadiums).
Yes, it features global voltage compatibility (110V/220V/230V). The amplifier automatically detects the input voltage, so no manual adjustment is needed. This makes it ideal for touring companies that operate in regions with different power standards (e.g., North America 110V, Europe 220V) and international installations (e.g., global hotel chains, multinational corporate centers).
