Proel D10A

The Proel D10A is a professional active DI box designed to balance and match the impedance of guitars, keyboards, and other line-level sources for direct connection to mixing consoles. Its transformer-isolated design eliminates ground loops and reduces hum and noise. Powered by phantom power, the active circuitry ensures zero insertion loss and clean, noise-free signal transmission.
