WELCOME
Congratulations on your purchase of the Radial ProDI or ProD2 direct box, two of the most versatile and useful pieces of
equipment you will likely ever own! Why do we say this? Simple: a good passive direct box can often fi nd its way into all
kinds of applications and be a real problem-solver for both live PA systems and studio recording. For example, the ProDI
can be used to eliminate noise, split signals, convert unbalanced lines to balanced, and can be used backwards to send
pre-recorded signals to a guitar amp for an eff ect called re-amping.
As with all Radial products, every attempt has been made to make the ProDI ‘plug & play’ easy-to-use. However, it is still
a good idea to read this manual thoroughly to ensure you take full advantage of all the features that are built-in, so that the
results you get are the very best possible. Should you have any questions on your new ProDI, please consult the Radial
website FAQ section, as this is where we publish questions and answers from users after a product has been released.
If you do not fi nd the answer you are looking for, feel free to send us an email at info@radialeng.com and we will do our
very best to get back to you promptly.
