Sumico SU2220 Professional Power Amplifier features the latest-generation advanced Class TD circuit, delivering high efficiency with a rated output of 2200W/channel (8 Ohms) and 3300W/channel (4 Ohms) for powerful and stable sound.
Sumico SU2220 Power Amplifier with Class TD topology is engineered to meet the stringent standards of the commercial audio market, demanding durability, efficiency, and superior sound reproduction.
With an output power of up to 2200W/channel (8 Ohms) and 3300W/channel (4 Ohms), Sumico SU2220 Power Amplifier effortlessly drives low-sensitivity full-range speakers or subwoofers without power loss. In bridge mono mode, the amplifier delivers up to 6600W (8 Ohms) and 8500W (4 Ohms), making it an ideal choice for dual subwoofer systems in outdoor stage setups or large line array systems. Its powerful performance is not merely about numbers but also about the ability to maintain stability under continuous heavy loads - an essential factor in real-world live performance conditions.
Sumico SU2220 Power Amplifier features standard dimensions of 132mm (Height) x 483mm (Width) x 490mm (Depth), featuring built-in rack ears for easy installation into an audio equipment rack, with a solid and sturdy chassis in an elegant, powerful matte black finish. The amplifier is designed with simplified functions, allowing users to easily monitor and control operating status. The front panel is crafted from precision-machined thick aluminum, highlighted by a set of intuitive controls, including a multi-color signal indicator array, rotary knobs, and a large, user-friendly power switch. In addition, the ventilated front grille not only enhances cooling efficiency but also adds a modern aesthetic accent to the overall design.
Sumico SU2220 Power Amplifier is equipped with standard connectivity for professional audio systems:
XLR inputs for convenient integration with mixers, digital processors, or any other audio sources.
XLR link outputs for signal pass-through from the inputs.
Output mode selector switch with three options: Stereo (two independent output channels for Left/Right inputs), Parallel (two output channels running in parallel from a single input channel), and Bridge (combining two output channels into a single high-power channel for driving large speakers such as dual subwoofers, delivering mono sound from one input channel).
Flexible speaker output options: Speaker terminals allow optional connections using banana plugs, Speakon–Canon connectors, or bare wires clamped directly.
Dual rear cooling fans operate quietly, ensuring maximum efficiency and reliable performance during long continuous operation.
