Unrivaled Audio Performance
Our transformerless, transimpedance mic preamp design effortlessly resolves complex sonic waveforms, ensuring recordings of stunning clarity and richness. Paired with integrated 192 kHz A/D conversion, the m108 sends pristine digital signals to your workstation via AES, ADAT, or USB. The latest s-Lock™ PLL provides jitter-free clocking from external word clock or Dante sources, while an asynchronous USB interface optimizes jitter performance for computer connectivity.
Intuitive Operation and Control
The m108 features a simple, intuitive interface with a push-button rotary encoder for navigation and dedicated buttons for core functions like 48V phantom power, phase reverse, channel grouping, and meter peak clear. A high-contrast OLED display offers a wide viewing angle, showing gain settings, metering, and system status. Remote control is effortless via the m108 Control Software (Windows/Mac) for up to 12 units, or the built-in web browser interface optimized for Chrome, accessible from any web-enabled device.
Versatile Connectivity and Expansion
With balanced analog outputs, AES3, ADAT (4-channel SMUX), and USB Class 2 connectivity, the m108 adapts to diverse setups. An expansion slot supports optional Digilink, Dante, or Ravenna (AES67/ST2110) cards, while the Control Room Output (CRO) option transforms it into a monitor controller for studio speakers. Hi-Z inputs on channels 1 and 2, a reference DAC, and a headphone amp ensure low-latency monitoring, making it a powerhouse for any audio workflow.
