Interchangeable Inputs & Outputs
AFM−20DSP is a high−performance, professional
audio matrix switcher with 20 analog ports that can be
configured as inputs or outputs according to preset I/O
configurations. AFM−20DSP includes multi−channel
DSP, built−in 2x60W @ 8Ω and 1x120W @ 70V / 100V
power amplifier, 4x4 Dante interface, HDMI
embedding and de−embedding, and S/PDIF. The
comprehensive and user−friendly graphic interface
makes configuring every detail of your audio system
intuitive and easy
FEATURES
High-Performance, Professional Audio Matrix Switcher-Professional, studio grade signal conversion
technology, Including the latest generation 32−bit advanced Digital Analog Converter architecture to
achieve excellent dynamic performance and improved tolerance to clock jitter. Maintains the quality
of the original audio signal with selectable sampling rates up to 96 kHz. Flat frequency response,
unmatched sonic performance, excellent signal to noise ratio, and extraordinarily low distortion levels
Wide Range of I/O Formats-Includes 20 analog ports, 4x4 Dante interface, HDMI input and output,
and S/PDIF input and output
Multi-Channel Processing-Provides DSP (Digital Sound Processing) that enables simultaneous
processing of all input and output signals
Built-in Power Amplifier-2x60W @ 8Ω and 1x120W @ 70V / 100V power amplifier
Maximum Flexibility-Customize the analog port configuration: use the default 12 x8 I/O matrix
configuration or select from one of the many other preset I/O configurations. Route any input to any
output:even between different formats (for example, route an analog input to an S/PDIF output).
Control volume and DSP per port. Route any of the ports to the power amplifier
Intuitive and Comprehensive Configuration and Control-Via a powerful, user−friendly graphic
interface, set volume (gain and attenuation) and DSP per input, execute routing, select line in, mic
in, phantom power or line out on each port, configure master level and more
Audio De-embedding-De−embeds the audio signal from the HDMI input for routing to any of the
outputs or for routing to the loop ouput
Programmable-Supports up to 10 global presets per I/O configuration plus 10 mixer snapshot
presets
Convenient Control-Via the user−friendly embedded web pages and RS−232 serial controller,
control signal routing, independent volume
Easy, Cost–Effective Maintenance-LED indicators for main power, line in/out, mic in, clipping,
power amp, Dante sync, and HDMI, enable easy local maintenance and troubleshooting. Local
firmware upgrade via the USB type–A port ensures lasting, field–proven deployment
Easy Installation-19” enclosure for rack mounting a unit in a 1U rack space with included rack ears
and universal 100–240V AC power connection
