HPA - AM-1100

The HPA AM-1100 power amplifier, with its 2 x 300 W_RMS on 8 ohms and 2 x 540 W_RMS on 4 ohms Class-AB amplifier stages, is specifically designed to provide exceptional robustness and reliability in a variety of professional environments.

It can also operate in mono bridged mode to deliver a massive 1100 W_RMS on 8 ohms, meeting the requirements of the most demanding audio systems. With a damping factor of over 200, this 2-channel power amplifier ensures excellent loudspeaker control, essential for accurate and distortion-free sound reproduction. The input impedance is 20 kohms in balanced mode and 10 kohms in unbalanced mode, offering great connection versatility. The HPA AM-1100 features XLR / RCA inputs and speakON and binding posts outputs, which allow for safe and reliable connections to other professional audio and Hi-Fi equipment. Switchable stereo, parallel and bridge modes increase flexibility to suit various configurations and applications. The amplifier incorporates electronic, thermal and electrical protection to ensure safe and continuous use, even in the most demanding conditions.

A signal-to-noise ratio of 95 dB and a THD of just 0.1% at 1 kHz indicate excellent performance, with little noise or distortion at high output levels. A frequency response of 20 Hz to 20 kHz within just ±1.5 dB ensures fidelity across the entire audio frequency spectrum, from deep bass to crystal-clear highs.
