The Metric Halo ULN-8 3d is a 24-bit / 192 kHz USB Type-C audio interface offering eight preamps and inserts, multichannel digital I/O, DSP-powered mixing, and software control for musicians, engineers, and producers in studios and mobile setups. Its integrated dual-core DSP powers a variety of plug-ins—the included DSP+ license unlocks over 100 of them—without burdening your computer's CPU. Robust software ensures easy access to multitrack recording, mixing, monitoring, and more.

The ULN-8 3d's eight microphone preamps are fed by DB25 mic/line inputs and two 1/4" Hi-Z DI inputs. All eight preamps feature phantom power, up to 91.5 dB of gain, and front-panel gain controls. Analog outputs include eight line outs via DB25, and a 1/4" headphone jack, which can be affected by the front-panel volume, mute, and dim functions. The ULN-8 also accommodates up to eight pieces of analog outboard gear via balanced inserts.

Properly synchronize with other equipment through the BNC word clock jacks and 1/4" SMPTE I/O. The 5-pin DIN connectors allow hookup of a MIDI control surface. Consolidate audio, clock, and data I/O with other 3d-equipped Metric Halo interfaces via the RJ45 MH Link ports. The ULN-8 3d connects to a compatible Mac, Windows, iOS, or Linux device via the supplied USB Type-A to USB Type-C cable. Power it with the included power supply or via a 4-pin XLR power system (available separately).

3d Card Features

  • MH Link: Low-latency, high-bandwidth audio, clock, and data connections via Gigabit Ethernet
  • MH Link Audio: Direct Ethernet Core Audio driver (with support for up to 128 channels of I/O at 192 kHz)
  • MH EdgeBus: A high-bandwidth, programmable, and pluggable audio expansion slot that accommodates a range of I/O expansion cards
  • MH Console: A 64-bit application to control your entire system with a simple, efficient, and flexible routing model (macOS only for Early Access versions)
  • MH Mixer: 128-input / 64-bus unified zero-latency mixer
  • MH MonitorControl: Integrated surround-capable monitor controller with system processing capability
  • MH Record: 128-input multitrack recorder with deep hardware integration
