## Questions & Answers

**Q: I have a radial pro48 active di. my interface gets too much signal out of it. will prodi send less? my pickups r active**
A: A common rule of thumb is to use an Active DI with a Passive Bass and a Passive DI with an Active Bass.  That allows the passive DI to handle the active bass hotter signal and the active DI to bump up the level from a passive bass.

**Q: Could this di be used to plug my electric drum set into my system?**
A: If your electric drums have a 1/4" output and your "system" has XLR input (just like my drums and mixer do) then the answer is YES.

**Q: Is this box good for electric guitar like fender stratocaster**
A: very good di, but it is a passive box. your guitar needs to send a line level signal into this di. I've connected this di from the output of a guitar amp or effects foot rack.

**Q: is this the one i need for active guitar pickups with a battery? emgs**
A: It should work with both passive and active pickup systems that use batteries.  I use it with both Fishman and L.R. Baggs systems.

Conosco la qualità Radial perché ho altri loro prodotti ma fino a poco tempo fa non avevo bisogno di una DI e soprattutto con 2 output. Ne ho provata una di altra marca, economica, ma l'ho dovuta restituire subito.. con questa PRO DI ho risolto il problema! Qualità del suono restituito eccezionale, lo valorizza senza colorarlo. Robustezza di un carrarmato. La qualità si paga e con i prodotti Radial Engineering si va a colpo sicuro ad occhi chiusi. Venditore eccezionale: il tutto è arrivato con 1 giorno di anticipo e impacchettato con cura e protezione più che adeguata.
