The Radial Engineering Pro-D2 Passive Direct Box is a professional-grade audio device designed for musicians and audio engineers looking to transfer balanced or unbalanced line-level signals from synthesizers, devices without an amplifier or active speakers, and electric instruments to a mixing console or recording interface. The Pro-D2 Passive Direct Box is a part of Radial Engineering's Pro-D Series, which is renowned for its compact size, high-quality components, and superior performance.
The Pro-D2 is constructed using Radial's carefully selected components, including a heavy-duty, transformer-coupled input stage, durable steel enclosure, and high-resolution opto-isolators that protect against RFI and EMI. The box is also equipped with a isolation transformer that ensures a clear and clean transfer of audio signals between devices.
One of the defining features of the Pro-D2 is its passive design, which eliminates the need for batteries or phantom power. This makes it an ideal solution for use in live settings where power sources may not be readily available. It is also a practical choice for studio applications, where batteries or phantom power are unnecessary and can potentially interfere with sensitive recording equipment.
The Pro-D2 Passive Direct Box is versatile and can be used with a wide range of instruments and sources, including bass, electric guitar, keyboard, and other line-level devices. Its transformer-coupled input provides 15dB of gain, allowing for seamless integration with different audio systems while maintaining the integrity of the original sound.
The unit's output is balanced, ensuring that the connected equipment is protected from potential noise introduced by ground loops. The Pro-D2 also features a ground lift switch, which helps to eliminate hum and noise caused by ground loops when used with multiple pieces of audio equipment.
Additionally, the Pro-D2 Passive Direct Box comes with a rugged, tour-grade 1/4 inch isolation jack, allowing it to be used with various mounting options, including the TR-POR-1 Standard Rack Kit for those who prefer to rack mount their gear. It also includes a standard 1/4 inch TS output connector for easy integration with mixers and recording equipment.
In summary, the Radial Engineering Pro-D2 Passive Direct Box is a high-quality and versatile audio tool designed for musicians and audio engineers who require a reliable and efficient method for transferring line-level or instrument level signals between devices. Its passive design, transformer-coupled input stage, and durable construction make it a go-to choice for live performances and studio applications alike.
