Q: Can I hurt my amplifier if the X-Amp is set too loud?
A: No. The X-Amp has been designed to work within the normal operating ranges of guitar amplifiers and effect pedals.

Q: Is there a difference between the direct and isolated outputs?
A: Output-A (direct) and output-B (isolated) have been designed to sound as close to the same as technically possible. The only difference here being that output-B employs a custom made isolation transformer to reduce hum and ground-loop buzz. Always connect output A first to ensure proper grounding.

Q: Why do you have to use output-A when using the X-Amp?
A: Output A is the primary ground path for the X-Amp and needs to be connected to a properly grounded amplifier so that the chassis can work as a screen against RF and other magnetically induced noise hazards. Keep in mind that the X-Amp employs a floating ground plane and needs to be grounded at either the input or the output.

Q: What should I do if I hear 60 cycle hum in my system?
A: Try depressing the ground lift switch at the XLR input side. This will disconnect the ground from the mixer and leave you with a direct-coupled ground at the primary guitar amplifier.

Q: I heard that the Radial JDI can be used backwards as a re-amping device?
A: Yes this is true. The Radial JDI, when driven ‘backwards’, will also reverse the impedance from low-Z to hi-Z and allow a padded down line level to drive the amp at a 10k-ohm level. The difference however is akin to comparing a passive direct box to an active direct box or like comparing a dynamic mic to a condenser. Active boxes tend to have more ‘reach’ or better high frequency transfer of upper harmonic detail.

Q: Can I drive effect pedals with the X-Amp?
A: Absolutely! The X-Amp is perfect for this type of thing! Connect the same way as with an amplifier as described in the manual. Have fun and experiment!

Q: Will my guitar effects sound the same if I bring them back into the mixer without going through my guitar amplifier??
A: No. Guitar effect pedals are designed to go through the limited bandwidth of a guitar amplifier where the highs are naturally rolled off by the absence of a tweeter. Going direct may sound fun but be aware that you may encounter noise that may have to be rolled off.

Q: Can I use a direct box with the X-Amp to extend guitar cables?
A: No. The X-Amp is designed for line-level inputs. To do this, you would require a mic preamp that can produce a line level output which in turn could drive the X-Amp hundreds of feet away.

Q: Where can I buy a Radial X-Amp?
A: Radial products may be ordered from professional audio and video outlets throughout the USA, Canada and around the world through our network of distributors. If you cannot find one locally, send us an email at info@radialeng.com and we will put you in contact with a dealer near you.
