GLABS, a fast-growing sub-brand of ATI Pro Technologies, introduces the powerful SP450H Amplifier—engineered for professional events, fixed installations, DJ setups and large venues. Designed with advanced Class H circuitry and robust build quality, this amplifier delivers consistent, high-output performance with exceptional clarity and control.
High-Powered Performance for Demanding Applications
The GLABS SP450H offers impressive stereo RMS output power of 2 x 450W @ 8Ω, 2 x 675W @ 4Ω, and 2 x 900W @ 2Ω, making it suitable for a wide range of speaker configurations. For applications requiring even greater power, the amplifier supports Bridge Mode, delivering 900W @ 16Ω, 1350W @ 8Ω, and a massive 1800W @ 4Ω. This flexibility ensures reliable performance whether you’re powering PA systems, line arrays, or high-demand subwoofers.
Superior Sound Quality & Control
With a wide frequency response of 10Hz–20kHz, the SP450H reproduces deep bass and crystal-clear highs with accuracy. Its outstanding S/N ratio of >100dB (20Hz–20kHz) ensures minimal noise and maximum audio clarity, while the damping factor of >5000 (8Ω) provides excellent speaker control and tight bass response.
The amplifier features selectable input sensitivity options (0.775V, 1V, 1.4V), allowing seamless integration with various mixers and processors, making it highly versatile for professional audio setups.
Advanced Protection & Durable Design
Safety and reliability are top priorities in the SP450H. It includes comprehensive protection systems such as short-circuit, DC, overload, overheat, ultrasonic, RF and voltage peak limit protection, ensuring stable operation even in demanding environments.
Built in a standard 2U rack-mount size (483mm × 350mm × 90mm), it fits easily into professional racks. Despite its powerful performance, it maintains a manageable net weight of 17.5 kg. The amplifier supports 110V/220V operating voltage and is equipped with an F-10A fuse for added safety.
Powered by advanced Class H circuitry, the GLABS SP450H combines efficiency, durability and high output performance—making it the perfect amplifier solution for events, venues and permanent sound installations.
