Burl Audio B80 Mothership 3 BMB4 SoundGrid

The Burl Audio B80 Mothership 3 equipped with the BMB4 SoundGrid Motherboard is an elite, high-capacity 10-slot modular AD/DA conversion system built for Waves SoundGrid real-time DSP environments, live sound touring, broadcast, and hybrid recording facilities. Combining Burl Audio's signature Class-A discrete analog signal path and custom transformer topologies with native SoundGrid audio-over-IP connectivity, the B80 Mothership 3 delivers up to 128 channels of near-zero latency conversion infused with classic analog warmth, depth, and tape-like saturation.

Powered by the BMB4 motherboard, the chassis connects directly into any Waves SoundGrid network via an RJ45 Ethernet port, enabling ultra-low latency plugin processing, multi-channel DAW tracking, and seamless integration with SoundGrid DSP servers and digital consoles. 

Key Features

• 10 Daughter Card Slots: Custom-configure your chassis using any combination of Burl BAD input, BDA output, B4 mic pre, BAES digital, and BCLK word clock modules.

• Waves SoundGrid Network Port (BMB4): Delivers up to 128 SoundGrid channels at $44.1\text{ kHz}/48\text{ kHz}$ base sample rates, 64 I/O at $88.2\text{ kHz}/96\text{ kHz}$, and 32 I/O at $176.4\text{ kHz}/192\text{ kHz}$.

• Automated I/O Slot Mapping: Motherboard-to-card communication automatically assigns channel numbers sequentially from left to right across slots.

• Class-A Discrete Analog Circuitry: Direct-coupled, zero-capacitor audio paths featuring proprietary BX1 input transformers for rich harmonic saturation and punch.

• External Heavy-Duty Power Supply: Includes external 1U power supply delivering continuous, high-voltage $\pm 24\text{V}$ rails to power 80+ channels of Class-A circuitry.

• Future-Proof Architecture: Prepared for next-generation high-density SoundGrid daughter cards supporting up to 64 channels per slot.
