Know before you buy
Class G amplification allows the amplifier to run in pure Class A mode for the first 20 watts, providing high-fidelity sound at lower volumes. As the signal demands more power, it switches to a more efficient class, ensuring you get both sonic purity and the headroom needed for dynamic peaks.
Yes, the PA720 features switchable inputs, allowing you to choose between balanced XLR or unbalanced RCA connections depending on your pre-amplifier's output capabilities.
The PA720 is optimized for 8-ohm speakers, delivering 100 watts per channel across all seven channels simultaneously. It is designed to handle demanding loads while maintaining low distortion levels.
The acoustically damped chassis is designed to minimize microphonic vibrations and resonance that can interfere with sensitive internal components. By isolating the circuitry, it helps ensure a cleaner, more detailed sound reproduction.
The amplifier includes both Ethernet and RS232 ports, allowing for seamless integration and control within custom home automation or multi-room audio systems.
Absolutely. With seven discrete channels of amplification and a robust toroidal power supply, it is specifically engineered to drive complex home theater configurations with the power and clarity required for immersive surround sound.
