HH Audio M-2600D 2 x 2600W Stereo Power Amplifier

Professional High-Power 2 x 2600W Stereo Power Amplifier With Toroidal Power Supply & Comprehensive Protection – HH M-2600D.

The HH M-2600D is a formidable high-power professional stereo power amplifier delivering 2 x 2600W at 4 Ohms, designed for the most demanding applications in larger clubs, concert venues, houses of worship, live music productions and any environment requiring serious high-fidelity amplification at scale. 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 5150W at 8 Ohms provides exceptional mono output power for the most demanding single-channel applications. Comprehensive protection circuits cover soft start, VHF, RF, short circuit, overload, clip limiting and overheat, and a damping factor of greater than 200 and slew rate of 20V/µS confirm the M-2600D's position as a serious professional tool. With over five decades of power amplifier design experience, HH remains one of the most trusted names in professional amplification.

Class H Design & Toroidal Power Supply

The M-2600D 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 exceptional 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 outstanding 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 20kΩ balanced and 10kΩ 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 5150W at 8 Ohms — making the M-2600D an exceptionally powerful choice for high-demand mono subwoofer or single-channel applications.

Rugged Construction & Comprehensive Protection

Built for professional use in the most demanding environments, the M-2600D 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.
