PA Amplifier The HPA AM-1100 power amplifier offers Class AB performance with a power rating of 2x 300 W RMS into 8 ohms and 2x 540 W RMS into 4 ohms, up to 1100 W RMS in bridge mode. Equipped with XLR and RCA inputs and speakON outputs, it is designed for reliability with full protection and efficient cooling, ideal for professional sound reinforcement requirements.

Presentation The HPA AM-1100 Class AB power amplifier is specially designed to offer exceptional robustness and reliability in a variety of professional applications. With its ability to deliver 2x 300 W RMS at 8 ohms and 2x 540 W RMS at 4 ohms, as well as an impressive 1100 W RMS in bridge mode at 8 ohms, this amplifier meets the requirements of the most demanding applications. This model boasts a damping factor of over 200, enabling it to precisely control the loudspeakers for crisp, accurate sound reproduction. Input sensitivity is fixed at 1 V, allowing easy integration with a variety of audio sources. The amplifier also offers dual input impedance options, with 20 kohms in balanced mode and 10 kohms in unbalanced mode, providing great connection flexibility. With a signal-to-noise ratio of 95 dB and a THD of just 0.1% at 1 kHz, the HPA AM-1100 delivers exceptional audio clarity. The extended frequency response from 20 Hz to 20 kHz, with a tolerance of ±1.5 dB, guarantees sonic fidelity across the entire audible spectrum, from deep bass to crystal-clear highs. Connections are made easy with XLR and RCA inputs, as well as speakON outputs and screw terminals, compatible with most PA set-ups. The mode switch makes it easy to switch between stereo and bridge configurations, adapting the amplifier to a variety of situations. Advanced protection systems against electrical and thermal surges and short circuits ensure safe, long-lasting use. The fan cooling system keeps the unit at an optimum temperature, while the 'soft start' function helps to minimise the risk of voltage spikes on switch-on, protecting sensitive components.
