Description
The Kramer AFM-20DSP is a high-performance 20-port audio matrix switcher engineered for professional AV environments requiring flexible routing, advanced DSP, and seamless format interoperability. Part of the Kramer XSPerience family, this versatile matrix features 20 configurable analog ports, allowing users to assign each port as an input or output based on preset I/O profiles.
Equipped with powerful multi-channel DSP, built-in 2×60W @ 8Ω and 1×120W @ 70V/100V Class-D amplification, 4×4 Dante networking, and HDMI audio embedding/de-embedding, the AFM-20DSP delivers unmatched signal processing performance. Its advanced 32-bit DAC technology ensures flat frequency response, ultra-low distortion, and exceptional audio clarity.
Designed for modern meeting spaces, auditoriums, and enterprise AV installations, AFM-20DSP includes Maestro room automation, intuitive configuration tools, and rich control options via RS-232, Ethernet, and web interface. With robust build quality, 1U rackmount design, LED status indicators, and easy field maintenance, this all-in-one matrix enables fast deployment, precise routing, and reliable long-term operation.
