Power amplifier Class-AB 2x540W/4Ω stereo/parallel/bridge - HPA MSC-HPAAM1100

The HPA AM-1100 is a 2-channel Class-AB power amplifier designed to provide robustness and reliability in a range of professional environments. It delivers 2 x 300 W RMS at 8 ohms and 2 x 540 W RMS at 4 ohms; in mono bridge mode it reaches 1100 W RMS at 8 ohms, meeting the requirements of demanding audio systems.

A damping factor above 200 provides effective loudspeaker control for accurate, distortion-free reproduction. Input impedance is 20 kohm in balanced configuration and 10 kohm in unbalanced configuration. XLR / RCA inputs and speakON plus screw / banana outputs allow secure connections to professional audio and Hi-Fi equipment.

A switch selects stereo, parallel or bridge operation, increasing flexibility for different configurations and applications. Electronic, thermal and electrical protection supports safe, continuous operation under demanding conditions; fan cooling and soft start are also included.

The 95 dB signal-to-noise ratio and 0.1% THD at 1 kHz indicate low noise and distortion even at high output levels. Its 20 Hz to 20 kHz frequency response, within ±1.5 dB, preserves fidelity across the complete audio spectrum, from deep bass to crystal-clear highs.
