X-Amp™ Using & Applications

The following is a short discussion on how to use the Radial X-Amp in the studio. For complete details, we suggest you download the X-Amp manual by clicking here or on the icon to the left. If you are familiar with Reamping you are set to read on. If you are not, we suggest you read the short primer called How to Reamp as a starting point. Reamping is easy and fun!

Making connections

As with all electronic gear, you should always turn volume levels down or equipment off before making connections. This will help protect more sensitive components such as tweeters from turn-on transients. The Radial X-Amp comes with a 15VDC power supply. As soon as you plug it in, the X-Amp will turn on and the front panel LED will illuminate. There is no power switch.

Start by connecting the output from your recording system to the X-Amp's XLR input. This is a +4dB balanced line level input. Make sure the level control is turned completely clockwise. Connect the X-Amp OUT-1 to your first amplifier. This is a direct buffered output.

Always test at a low level before you crank it up! Hit play. Your dry track should be playing and the signal should be feeding the X-Amp. Turn up the level on your amp. Now turn up the level on the X-Amp. You should hear sound. Adjust the level to suit. If by chance you hear hum or buzz, try lifting the ground by depressing the ground lift switch.

Adding a second amp

You are now set to add another amp by simply connecting OUT-2 from the X-Amp to your second guitar amplifier. Because output-2 is transformer isolated, it will usually do away with the hum and buzz that is common when connecting using than one amp at the same time.

When using two amps you may find that one is out of phase with the other. This is common. To test, bring both amps close together and face them to each other. If out of phase the sound will be more distant and wide. When in phase, it will sound fatter with more bottom end. Try reversing the phase by depressing the 180° polarity reverse switch.

Adding pedals to the signal chain

For even more fun and tonal experimentation, try adding guitar pedals to the signal chain in between the X-Amp and your guitar amplifier. This can lead to interesting results on guitar, bass, drums and vocals. There are no rules – only creative possibilities! Note that pedals will also sometimes reverse the polarity of the signal so if you are using two amps, you may have to bring the second one in phase again by depressing the 180° polarity switch.
