Burl Audio B80 Mothership 3 BMB3 Dante

The Burl Audio B80 Mothership 3 equipped with the BMB3 Dante Motherboard is an elite, high-capacity 10-slot modular AD/DA conversion system built for AoIP networked audio infrastructures, hybrid recording studios, broadcast facilities, and live sound installations.

Powered by the BMB3 motherboard, the chassis integrates seamlessly into any Dante network via dual RJ45 Ethernet ports, enabling low-latency multi-channel routing through Dante Controller to digital consoles, DAWs, and networked audio processors. Driven by the BURL BACKBONE internal clocking architecture, master clock signals distribute directly across the backplane to each card slot without individual phase-locked loops (PLLs), ensuring razor-sharp stereo imaging, low jitter, and sample-accurate synchronisation across your network.

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.

• Dual Dante Ethernet Ports (BMB3): Delivers up to 128 Dante 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 Dante daughter cards supporting up to 64 channels per slot.
