MOTU 16A 32 x 34 Thunderbolt 4 / USB4 Audio Interface

Designed as the central hub of a high-performance recording or live-sound environment, the MOTU 16A is a 32-in / 34-out audio interface featuring Thunderbolt 4 and USB4 connectivity, onboard DSP mixing and effects, AVB networking, and advanced A/D/A conversion supporting up to 32-bit / 192 kHz resolution. The unit integrates a 64-channel DSP-driven monitor mixer with 32-bit floating-point internal processing, enabling low-latency routing and effects independent of host CPU load. A full digital patch bay provides flexible signal routing between physical I/O, the internal mixer, computer channels, and the AVB network.

The 16A supports 66 simultaneous audio channels locally and enables up to 256 channels of low-latency streaming over Thunderbolt to a host system. It also offers a full range of digital connectivity options including ADAT/SPDIF and Wordclock I/Os. The unit operates in multiple modes: as a standalone digital mixer, as an audio interface for macOS, Windows, or iOS devices, as an AVB network node, or any combination thereof. Comprehensive control of the mixer and system settings is provided via the CueMix Pro application. To jumpstart your workflow, Performer Lite production software is included, along with a comprehensive library of loops and sounds from industry leaders like Big Fish Audio, Lucidsamples, and Loopmasters.

Superb Analog-Audio Quality

The 16A features ESS Sabre32 DAC technology for pristine sound with 125 dB dynamic range and ultralow distortion�backed by decades of MOTU audio expertise.

66 Simultaneous Audio Channels

Includes 16 balanced/unbalanced TRS analog I/O, dual 8-channel ADAT optical ports, and a dedicated stereo headphone out�totaling 32 inputs and 34 outputs. Use the 16A as expanded analog I/O, a flexible patchbay/mixer, or both.

Connect via Thunderbolt 4 or USB4 with the included 40 Gbps USB-C cable. Enjoy plug-and-play compatibility with Mac, Windows, and iOS.

Supports Thunderbolt 3, USB3, and USB2�delivering up to 256 channels of I/O (128-in / 128-out) at 96 kHz.

Ultralow Latency Performance

Optimized drivers deliver round-trip latency as low as 1.8 ms at 96 kHz with a 32-sample buffer over Thunderbolt and USB, using high-performance DAWs like Digital Performer.

Plug-and-Play with Massive Bandwidth

Daisy-chain up to six Thunderbolt devices with 40 Gbps bandwidth�handling hundreds of audio channels, 8K video, and terabytes of data with ease. Thunderbolt 4�compatible cable included.

The internal mixer mirrors a large-format console with 64 inputs from any source: analog, digital, host software, network streams, or mixer buses.

Includes 26 aux buses, main, reverb, monitor, and solo buses�all with 4-band EQ and compression. Inputs also feature HPF and gating.

Intuitive Patchbay Routing and Splitting

Easily route any source to any destination via virtual patch cables. Split any source to multiple outputs, whether from interface I/O, host software, or AVB network devices.

Integrated AVB switch with dual Gigabit Ethernet ports supports daisy-chaining or external AVB switch expansion.

Each unit transmits and receives 128 channels over the network, with ultralow latency across long cable runs. Fully compatible with legacy MOTU AVB devices.

CueMix Pro gives complete control over mixing, routing, and settings wirelessly from macOS, Windows, or iOS.

Multiple devices can control the 16A simultaneously via Wi-Fi.

TRS connections are fully balanced and engineered to reject RF interference, AC hum, and environmental noise.

All analog outputs are DC-coupled, allowing CV sequencing of modular synths directly from your DAW.

Two ADAT banks support 16 channels at 48 kHz, 8 S/MUX channels at 96 kHz, or optional stereo TOSLINK up to 96 kHz.

Use the 16A as an optical expander or interface.

Tailor your workflow with customizable meter views for analog I/O, digital I/O, or combined configurations.
