DSP

AFM−20DSP−LE is a member of the Kramer XSPerience family of DSP products. AFM−20DSP−LE is an advanced, professional audio matrix switcher with 20 analog ports that can be configured as inputs or outputs according to preset I/O configurations. AFM−20DSP−LE includes multi−channel DSP and a comprehensive and user−friendly graphic interface that makes configuring every detail of your audio system intuitive and easy.

• Advanced 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.
• Multi–Channel Processing — Provides DSP (Digital Sound Processing) that enables simultaneous processing of all input and output signals.
• Maximum Flexibility — Customize the analog port configuration: use the default 12 x 8 I/O matrix configuration or select from one of the many other preset I/O configurations. Route any input to any output.
• Simple and Powerful Maestro Room Automation — Intuitive user interface enables you to fully automate your meeting room elements. Configure lights, shades, devices and more to be activated by an extensive range of triggers, including input/output connectivity, routing, and button pressing. By minimizing user intervention, Maestro room automation saves meeting prep time and minimizes human error before presentations.
• Intuitive and Comprehensive Configuration and Control — Via a powerful, user–friendly graphic interface, set volume (gain and attenuation) and DSP per input; execute routing and select line in, mic in, phantom power or line out on each port; configure master level and more. Control signal routing, volume and other basic settings using API commands via RS–232 communication transmitted by a PC, touch screen system or other serial controller.
• Programmable — Supports up to 10 global presets per I/O configuration plus 10 mixer snapshot presets.
• Easy, Cost–Effective Maintenance — LED indicators for main power, line in/out, mic in, and clipping enable easy local maintenance and troubleshooting. Local firmware upgrade via the USB 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.

The 1248 Thunderbolt audio interface provides industry-leading dynamic range and large console style mixing with 48 channels and 12 stereo busses. With 66 channels of audio I/O (32 ins and 34 outs), the 1248 also supports USB 2.0 audio class compliant connectivity that is USB 3.0 compatible. Powerful DSP delivers 32-bit floating point mixing and effects, including modeled analog EQ, vintage compression and classic reverb. The unit's extensive routing grid patches ins to outs, or splits inputs to multiple destinations. Use the 1248 as a stand-alone mixer and control everything from the 1248's innovative web app running on your iPad, iPhone, tablet, smart phone, and laptop. Connect a second MOTU AVB interface with a simple Ethernet cable. Add more I/O with the MOTU AVB Switch (sold separately). Build an AVB audio network with multiple switches and sub-millisecond latency, even over long cable runs. Stream hundreds of channels among devices and computers on the network. From initial tracking to final mastering, the 1248 delivers superb sound quality, state-of-the-art operation, and reliable performance.

Features:

• Superb audio quality - Exceptional dynamic range (123 dB on analog output) and THD N (-110 dB).
• 66 simultaneous audio channels - 4 mic inputs, 2 guitar inputs, 8x12 balanced analog with dedicated main and monitor outs, ADAT optical and S/PDIF digital (with SRC) for 32 inputs and 34 outputs.
• Universal connectivity - Thunderbolt or high-speed USB 2.0 (compatible with USB 3.0). USB audio class-compliant firmware and Industry standard drivers work with any audio software.
• On-board 32-bit floating point DSP with large console style mixing and effects - Flexible 48-input digital mixer with 12 stereo busses and DSP effects, including reverb with sends, plus modeled analog EQ and compression, gate, and reverb.
• System expansion and audio networking - Add a 2nd MOTU interface with a simple Cat-5e ethernet cable. Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately). Build a network with multiple interfaces and computers using standard AVB switches and network cabling, with ultra-low network latency, even over long cable runs (hundreds of meters). Stream hundreds of audio channels among devices and computers on the network.
• Matrix routing and splitting - Flexible, matrix-style audio routing and splitting for any analog or digital input, computer channel or network stream to any other output, computer, or network device. Split any single input to unlimited multiple output destinations.
• Web app control - Control on-board DSP, mixing, device settings, and network audio routing from web app software running in your favorite browser on a laptop, tablet or smart phone connected by wire or Wi-Fi to your local area network.
• Stand-alone mixing with wireless control - Connect an Apple Airport or other Wi-Fi router directly to the 1248 with a standard Ethernet cable and control the 1248's powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing.
