• Next-gen 32 x 34 Thunderbolt 4 / USB4 audio interface — The world’s first Thunderbolt 4 audio interface built on 30 years of proven success as an industry-leading audio interface brand.
• New 3.9-inch TFT displays — Two bright, 24-bit RGB LCDs provide 480 x 128 pixel high-resolution metering for all analog and digital I/O, plus detailed status info and access to hardware settings from a simple and convenient menu.
• Superb analog audio quality and high-end converters — Renowned ESS Sabre32™ DAC technology delivers 125 dB dynamic range. Support for all standard sample rates up to 192 kHz.
• Ultra-low latency and proven, high-performance MOTU drivers — Round-trip latency (RTL) performance as low as 1.8 ms at 96kHz with high-performance DAW hosts.
• Universal Thunderbolt/USB-C connectivity — Connect to any computer with the included 40 Gbps Thunderbolt-compatible USB4 cable  (compatible with USB3 and USB2) for up to 256 audio channels (128 in and 128 out), depending on the host computer connection. Class-compliant firmware and industry standard drivers work with any audio apps. Connects to an iPad™ with USB-C or a Lightning adapter kit (sold separately). Use the second Thunderbolt port to connect additional computer peripherals, a USB hub or Thunderbolt dock.
• 66 simultaneous audio channels — 32 inputs and 34 outputs, including 16 TRS analog (line-level) in/out, two banks of 8-channel optical I/O, and a front-panel headphone output.
• 64-channel mixing with effects — Powerful 32-bit floating point DSP delivers 64-channel mixing with 64 inputs, 32 busses, and effects processing, including reverb, 4-band double-precision EQ, high-pass filter, gate and compression at all sample rates up to 96 kHz.
• Patchbay routing and splitting — Using intuitive, virtual patch cords, easily route any source signal to any destination. Split any source to multiple destinations.
• AVB Networking — Use two Gigabit network ports to daisy-chain multiple units using standard network cabling, or add an AVB switch to build a network with multiple interfaces and computers 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. Compatible with previous-generation MOTU AVB devices.

• Wi-Fi control — Control everything wirelessly over Wi-Fi from the CueMix Pro app running on mobile devices or other computers on the same network — even multiple devices at the same time.
• Precision boost/trim for analog I/O — Calibrate analog input and output signals in precise 1 dB increments. Apply phase invert individually to analog inputs.
• Control room features — Control your sessions with "talk" button and "A/B/C" speaker select buttons to quickly compare your mixes on three sets of studio monitors.
• Flexible headphone output — With independent volume control and front panel source select knob, the headphone output can mirror any output pair, any CueMix bus, or any Thunderbolt/USB channels. Or create a completely customized mix that includes live 16A inputs and built-in reverb.
• Two banks of optical I/O — Connect outboard digital processors, digital mixers or other gear with 16 channels of ADAT at 44.1/48 kHz or 8 channels of S/MUX at 88.2/96 kHz. Bank A can optionally provide stereo TOSLink (optical S/PDIF) I/O up to 96 kHz.
• Word clock in/out/thru — Supports all sample rates up to 192 kHz.
• DC-coupled TRS outputs — Use the 16A to manipulate and sequence voltage-controlled modular synthesizers from a host DAW.
• Loopback for live streaming and podcasting — Easily route computer output back to the computer, where you can mix it with live inputs from the 16A in your host software for live streaming or podcasting.
• Flexible front-panel metering — Choose customized meter views for analog I/O only, digital I/O only and other combinations to best support your workflow.
• CueMix Pro app — Control mixing and settings from your Mac, PC or iOS device.
• Performer Lite — Workstation software with over 100 included instruments, dozens of effects and 6 GB of included loops to make music right away.
