HPA - DA-600

The HPA DA-600 power amplifier is a 1U rack-mount Class-D model capable of delivering 2 x 300 W_RMS on 8 ohms and 2 x 450 W_RMS on 4 ohms.

It can also be operated in mono bridged mode to deliver 900 W_RMS on 8 ohms, meeting the demands of PA and event professionals. With a damping factor > 200, this 2-channel power amplifier ensures excellent speaker control, essential for clear and detailed sound reproduction.

The input impedance is 20 kohm in balanced mode and 10 kohm in unbalanced mode, which offers great connection versatility. The HPA AM-1100 is equipped with XLR / jack inputs and speakON and binding posts outputs, which allow for safe and reliable connections to other professional audio equipment. Switchable stereo and bridge modes increase flexibility to accommodate various setups 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 100 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 ±0.5 dB ensures fidelity across the entire audio frequency spectrum, from deep bass to crystal-clear highs.
