Round-trip latency (RTL) performance as low as 1.6 ms at 96kHz over Thunderbolt™ with high-performance DAW hosts.
Mobile operation and universal connectivity
Connects to your computer with Thunderbolt™, super-speed USB 3.0, or AVB/TSN Ethernet for up to 256 audio channels (128 in and 128 out). Class-compliant firmware and Industry standard drivers work with any audio apps. Connects to iPad™ with a standard camera connection kit (adapter).
34 simultaneous audio channels
8 x 8 balanced analog, 8-channel ADAT optical, and independent phone out for 16 inputs and 18 outputs.
DSP mixing and effects processing
Flexible 48-input digital mixer with 7 stereo aux busses, 3 group sends, access to 64 network inputs, and DSP effects, including reverb, 4-band EQ, gate, and compression.
32-bit floating-point processing
The 8A’s mixing and effects DSP engine delivers virtually unlimited headroom and the utmost in sound quality.
Modeled vintage effects processing
Classic reverb. Compression modeled after the legendary LA-2A compressor. EQ is modeled after British analog console EQs.
Flexible matrix routing and splitting
Send any input to any output, or multiple outputs. Includes routing to and from the computer, plus any devices on the audio network.
Stand-alone operation with wireless control
Connect an Apple® Airport™ or other Wi-Fi router with a standard Ethernet cable for wireless control of device settings, powerful 48-channel mixing, and DSP effects.
Web app control from any device
