All 56 microphone inputs are directly connected to a multipin output (Main Out) and routed through premium Whirlwind TRSP-2F transformers to two isolated multipin outputs (ISO 1 and ISO 2). Each microphone input features an individual ground lift switch, while the final two inputs additionally include parallel-wired return interfaces.

The unit features gold-plated XLR connectors and high-strength military-grade Whirlwind multipin connectors, with both front and rear panels constructed from durable metal materials.

For optimal protection, the system can be housed in a 16U multilayer plywood flight case offering impact-resistant, waterproof, and shockproof properties, ensuring safe and stable operation.
