Burl Audio B16-BMB4-M3-1612 — a ready-made AD/DA system in a B16 Mothership 3 chassis, fitted with a BMB4 SoundGrid motherboard, a BAD16 card (16-channel ADC), and a BDA12 card with twelve line outputs plus a built-in two-channel class-A monitor section.
Input conversion runs through transformer-coupled, discrete class-A circuitry with the BX8 transformer, while the line and monitor outputs use a discrete class-A path with the BOPA14 op-amp. The BMB4 motherboard provides a single Ethernet port carrying up to 64 input and output channels at 44.1kHz to 96kHz over the Waves SoundGrid protocol.
Direct integration with the SoundGrid ecosystem
Studios running on Waves SoundGrid often need to add a separate AD/DA converter to the network, which complicates cabling and adds latency. The BMB4 addresses this with a direct, low-latency Ethernet connection to SoundGrid servers, DAWs and consoles, with no interfacing card in between. Sixteen input channels with the BX8 transformer go straight onto the audio-over-IP network, keeping the BURL Audio analog character intact.
A complete system with monitoring in one chassis
A compact SoundGrid rig usually needs a separate monitor controller just to switch between speakers and headphones, adding one more box to the rack. The BDA12 card removes that step by integrating a switchable Speaker A, Speaker B and Headphones section right on the DAC card, running through the same class-A path as the twelve line outputs. That means a sixteen-in, twelve-out set with full monitor control fits in just two rack units, with no extra cabling to an outboard controller.
