Klipsch KDA Series 4-Channel Class G/H Power Amplifier

The Klipsch KDA Series DSP Amplifiers offer exceptional performance and flexibility in a compact 1U rack-mountable design, ideal for both residential and commercial installations. Available in two power variants—KDA-500 and KDA-1000—these amplifiers provide efficient Class G/H topology for high output with minimal distortion. Each model supports 70V/100V and low impedance systems, with a suite of professional-grade features for fine-tuned system control.

Both models feature 4 channels of audio, with balanced Phoenix and unbalanced RCA inputs, Phoenix speaker-level outputs, and RCA line-level throughs. A web-based DSP interface enables easy setup and real-time adjustments for zone-specific sound optimization. Housed in a sleek black anodized aluminum chassis, these amplifiers are built for reliable performance and seamless integration into any audio system.
