A direct box is an essential tool for recording and live sound applications. It makes a line-level signal from a high-impedance instrument or microphone-level source suitable for a balanced low-impedance input, such as those found on mixing consoles, studio preamps and audio interfaces. The direct box also often provides isolation to eliminate hum and buzz caused by ground loops. With so many direct boxes on the market, it can be difficult to choose the right one for your needs. This article will discuss the best direct boxes available and how to choose the right one for your application.
