A direct box is a valuable tool for capturing and amplifying audio signals. While the device may seem daunting to use or purchase, it’s actually quite simple and straightforward. Here’s a beginner’s guide to buying a direct box.
First, decide what type of signal you will be connecting your direct box to. There are devices designed specifically for instrument-level sources, such as electric guitar and bass. If you plan on connecting to either of those two instruments, look for a direct box designed specifically for that instrument.
Next, decide on the size and type of direct box you want. Generally, direct boxes come in two sizes—half-space and full-space. Half-space models are smaller and easier to transport and fit better into cramped environments. Full-space models provide more features and gain. Additionally, some direct boxes have multiple outputs and others have switchable input and output impedances. Consider the size and type of direct box you need for your application.
Finally, determine the budget you have for a direct box. Prices can range from quite affordable to quite steep, depending on the features and quality of the device. Do some research on the different types of direct boxes available within your budget.
After following these steps, you should be able to confidently purchase the right direct box for your needs. Take your time and make an educated purchase, and you'll be sure to find a direct box that fits your requirements perfectly.
