HH Audio M-1500D 2 x 1500W Stereo Power Amplifier

Professional High-Power 2 x 1500W Stereo Power Amplifier With Toroidal Power Supply & Comprehensive Protection HH M-1500D. The HH M-1500D is a high-power professional stereo power amplifier delivering 2 x 1500W at 4 Ohms, designed for demanding applications in bars, clubs, houses of worship, live music venues and anywhere requiring high-fidelity, high-power amplification. Part of the HH M-Series range, it features a Class H high performance professional linear design and a heavy duty low noise toroidal power supply, providing a clean, stable and reliable power foundation for sustained high-output operation. Rugged construction and a standard 19″ 2U rack-mount format make it well suited to both permanent installations and touring rigs, and a variable speed front-to-back forced air cooling system ensures safe and efficient thermal management during extended use. Balanced XLR inputs with user-selectable input sensitivity (0.775V/1.4V) ensure compatibility with a wide range of professional source equipment, and locking SpeakON connectors alongside 4mm binding posts with safety covers provide secure and versatile speaker connectivity. Balanced XLR link outputs allow straightforward daisy-chaining to additional amplifiers, and a bridged output of 2900W at 8 Ohms provides further flexibility for mono high-power applications. Comprehensive protection circuits cover soft start, VHF, RF, short circuit, overload, clip limiting and overheat, while a damping factor of greater than 200 and a slew rate of 20V/S underline the M-1500D’s credentials as a serious professional amplifier. HH has over five decades of experience designing quality power amplifiers, making the M-Series a trusted choice for professionals worldwide. Class H Design & Toroidal Power Supply The M-1500D employs a Class H high performance professional linear amplifier design, which improves efficiency over conventional Class AB designs by dynamically scaling the supply voltage to track the audio signal delivering high output power with reduced heat generation and improved reliability over extended use. The heavy duty low noise toroidal power supply provides a clean and stable power foundation, minimising mains-borne interference and contributing to the amplifier’s exceptional signal-to-noise ratio of 100dB or greater. Comprehensive Input & Output Connectivity Balanced XLR inputs with user-selectable sensitivity of 0.775V or 1.4V accommodate a wide range of professional mixers and source equipment, with an input impedance of 20k balanced and 10k unbalanced. Speaker outputs are provided via two locking SpeakON connectors and four 4mm binding posts with safety covers, while balanced XLR link outputs enable convenient signal routing to additional amplifiers in multi-amplifier setups. Bridge mode delivers a combined mono output of 2900W at 8 Ohms for applications requiring maximum single-channel power. Rugged Construction & Comprehensive Protection Built for professional use in demanding environments, the M-1500D features a comprehensive suite of protection circuits covering soft start, VHF and RF interference, short circuit, overload, clip limiting and overheat ensuring the amplifier and connected speaker systems are protected at all times. A variable speed forced air cooling system with front-to-back airflow maintains safe operating temperatures during sustained high-output operation, and per-channel volume controls alongside a bridge/routing mode switch give operators straightforward and flexible control over the system configuration.
