Before you take the stage or hit the record button, ensure your audio signal is pristine with the Pro Co Sound CB1 Standard Passive Direct Box. This high-quality, durable direct box is engineered to deliver clean, reliable performance with a wide array of unbalanced signal sources. Whether you're working with electric bass, acoustic guitar pickups, keyboards, drum machines, or mixer outputs, the CB1 transforms your sound into a balanced signal, free from distortion and coloration. The CB1's innovative design includes a hi-z to lo-z transformer and a hum eliminator, which work together to enhance the sound quality of your audio signal. This professional-grade direct box is a convenient, low-cost alternative to micing speakers, effectively reducing unwanted noise such as bleed and leakage from other instruments. The result is a crisp, clean, and full signal that retains the awesome bass and brilliant sound of digital instruments like synthesizers and digital-sampling drum machines. Crafted for the discerning musician or audio engineer, the CB1 boasts Pro Co's heavy-duty Uni-box construction, shared with the premium TradeTools DB1 Direct Box. Its rugged 16-gauge steel and aluminum enclosure is finished in a sleek black with a bold blue Lexan overlay, featuring high-visibility control and connector identification graphics for ease of use in any setting. The CB1's design also includes a ground lift switch, providing the flexibility to eliminate hum and buzz by addressing ground loops and ensuring proper grounding under various conditions. The switch's GND position connects input and LO-Z output grounds, while the Lift position 'floats' the LO-Z Output for optimal sound quality. For those who prioritize convenience, the CB1 is a passive direct box, meaning it operates without the need for an external power source, batteries, or power adapters. This makes it an ideal choice for on-the-go musicians and live sound engineers who need a reliable, plug-and-play solution. Moreover, the CB1's uniquely slotted side channels allow for seamless stacking or side-to-side strapping of multiple Pro Co TradeTools devices, thanks to the Uni-box construction. This feature ensures a tidy and organized setup, whether on stage or in the studio. In summary, the Pro Co Sound CB1 Standard Passive Direct Box is an essential tool for anyone looking to preserve the integrity of their sound in a professional audio environment. Its combination of high-quality components, innovative features, and rugged construction makes it a top choice for achieving superior audio performance.
