ATI Pro Technologies presents the BL4500 Ver 4.0 Amplifier, a next-level 4-channel professional power amplifier designed to meet the demands of modern live sound and permanent audio installations. Built on advanced Class-H amplification technology, this amplifier combines extreme power output, sonic accuracy and system safety, making it a reliable backbone for high-performance PA systems.
Massive Power Output for Demanding Audio Setups
The BL 4500 Ver 4.0 delivers exceptional power across multiple impedance levels, allowing sound engineers maximum system flexibility. It produces 4×1500W at 8Ω, 4×2800W at 4Ω and a massive 4×4500W at 2Ω in stereo mode. For larger systems, bridge mode operation offers 2×3000W at 8Ω and 2×5600W at 4Ω, making it ideal for driving powerful subwoofers and full-range speaker arrays in large venues.
Precision Sound with Superior Control
Designed for clean and accurate sound reproduction, the amplifier features a wide frequency response of 10 Hz to 20 kHz, ensuring deep bass, clear mids and crisp highs. With a signal-to-noise ratio above 100 dB, it delivers noise-free audio even at high output levels. The extremely high damping factor greater than 3000 (8 ohms) provides tight control over speaker movement, resulting in punchy low frequencies and improved overall clarity.
Built-In Protection for Long-Term Reliability
To ensure safe and stable operation, ATI Pro Technologies has integrated advanced protection circuits. The BL 4500 Ver 4.0 is safeguarded against short-circuit, DC overload, overheating, ultrasonic signals, RF interference and voltage peak limits, making it dependable for continuous operation during live shows and permanent installations.
Installation-Friendly Design & Global Compatibility
The amplifier supports multiple input sensitivity options (0.775V, 1V, 1.4V), allowing seamless integration with professional mixers and signal processors. It operates on 110V or 220V power, ensuring compatibility across different regions. Its 2U rack-mount chassis (483×436×90 mm) makes it perfect for touring racks and fixed equipment rooms.
Perfect Choice for Professional Applications
The BL 4500 Ver 4.0 is ideal for concerts, clubs, auditoriums, DJ systems, houses of worship and large installed PA setups. With its powerful performance, advanced safety features and trusted build quality, ATI Pro Technologies once again sets a high standard in professional amplification.
