Kramer AFM-20DSP-AEC 20-Port Audio Matrix with DSP, AEC
Product Overview
The Kramer AFM-20DSP-AEC is a 20-port professional audio matrix switcher with multi-channel DSP and Acoustic Echo Cancellation (AEC), designed for conference rooms, boardrooms, and commercial meeting spaces where clear, intelligible audio is essential for hybrid and in-room communication. As a member of Kramer's XSPerience DSP family, it provides a complete audio processing platform with built-in amplification, Dante networking, HDMI audio I/O, and AEC in a single rack-mount unit. AV integrators and system designers deploy the AFM-20DSP-AEC in unified communications and huddle room audio systems where microphone echo cancellation and flexible matrix routing eliminate the need for separate DSP processors and amplifiers. The comprehensive GUI makes system configuration and tuning accessible without requiring dedicated DSP programming expertise.
Key Features
- 20 Configurable Analog Ports — Ports can be assigned as inputs or outputs in multiple preset I/O configurations to match room requirements.
- Acoustic Echo Cancellation (AEC) — Built-in AEC removes far-end echo from conferencing audio, ensuring clear two-way communication.
- Built-In Power Amplifier — Integrated 2x60W @ 8Ω and 1x120W @ 70V/100V amplifier eliminates the need for external amplification in most conference room installs.
- 4x4 Dante Interface — Native Dante audio networking for integration with Dante-enabled microphones, processors, and distribution systems.
- HDMI Audio Embedding and De-Embedding — Routes audio between analog domain and HDMI video signals for AV-over-IP and presentation systems.
- 32-Bit DAC Architecture — Studio-grade analog conversion with selectable sampling rates up to 96kHz for high-fidelity audio reproduction.
- USB Plug-and-Play Audio — USB audio port for direct connection to laptop-based conferencing platforms without additional interface hardware.
- S/PDIF I/O — Digital audio I/O for connection to digital signal processors, recording systems, and digital amplifiers.
Typical Applications
- Corporate boardroom and executive conference room audio systems
- Hybrid meeting room unified communications deployments
- University lecture hall and seminar room audio
- House of worship sound reinforcement and recording
- Multi-purpose training rooms with mixed audio sources
- Government and municipal meeting chambers
Frequently Asked Questions
What makes AEC important in a conference room installation?
Acoustic Echo Cancellation removes the echo created when a room's loudspeakers feed back into microphones during conferencing calls. Without AEC, remote participants hear a delayed echo of their own voice, severely degrading call quality. The AFM-20DSP-AEC's built-in AEC handles this without requiring a separate processor.
Can the AFM-20DSP-AEC replace a separate amplifier?
In most conference room and mid-size meeting space installations, yes. The built-in 2x60W @ 8Ω stereo amplifier and 1x120W @ 70V/100V amplifier handle typical in-room speaker loads. For larger venues with higher SPL requirements, an additional amplifier may be needed.
Does it integrate with Dante audio networks?
Yes. The AFM-20DSP-AEC includes a 4x4 Dante interface, allowing it to send and receive audio over a standard Ethernet network alongside Dante-enabled microphones, processors, and other AV infrastructure.
How is the AFM-20DSP-AEC configured?
Configuration is performed via Kramer's GUI-based software tool, which provides intuitive matrix routing, EQ, gain, and AEC parameter controls. The interface is browser-accessible over Ethernet, making remote setup and adjustment practical for integrators.
What control protocols does it support?
The AFM-20DSP-AEC supports RS-232 and Ethernet (Kramer Protocol 3000) for integration with third-party control systems including Crestron, AMX, and Extron.
