Frequently Asked Questions - X-Amp 500 Radial Engineering
What is the Radial Engineering X-Amp 500 used for?
The X-Amp 500 is a 500-series re-amping amplifier that converts balanced line-level signals into unbalanced instrument-level signals. This allows you to send pre-recorded tracks from your DAW through guitar pedals, effects, or amplifiers to capture a more organic and authentic sound.
How do I connect the X-Amp 500 in my studio setup?
Connect the line-level output from your audio interface to the balanced 1/4" TRS input of the X-Amp 500. Then run a standard guitar cable from the unbalanced 1/4" TS output to your guitar amp or effects chain. Adjust the Output Level knob and use the -15dB Pad for lower input signals.
Can I use the X-Amp 500 with bass or acoustic guitars?
Yes, the X-Amp 500 is designed to work with any instrument-level load, including bass amps, acoustic guitar preamps, and even vintage effects units. Its high-current Class-A output ensures a clean and responsive signal regardless of the instrument.
Does the X-Amp 500 need its own power supply?
No. The X-Amp 500 is a 500-series module and receives its power directly from the rack's backplane at ±16V DC. It draws minimal current, so no external power source is required.
What is the purpose of the -15dB pad?
The -15dB pad attenuates the input level, allowing you to connect hotter line-level sources (up to +20dBu) without clipping. This is useful when working with very hot signals from modern converters or external preamps.
How do I use the Ground Lift switch?
The Ground Lift switch disconnects the audio ground from the chassis ground, eliminating hum and buzz caused by ground loops. Move it to the lift position if you experience noise when connecting to certain amplifiers.
What kind of cable should I connect from the X-Amp 500 to a guitar amp?
Use a standard unbalanced 1/4" TS instrument cable. Keep the cable length as short as practical to minimize capacitance and high-frequency loss, especially when driving high-impedance amp inputs.
Can I use the X-Amp 500 with line-level effects instead of an amp?
Yes, the X-Amp 500 can drive any line-level processing gear such as rack effects, EQs, or compressors. Simply set the level control to suit the input sensitivity of the equipment you are feeding.
Will the X-Amp 500 work with all 500-series racks?
The X-Amp 500 follows the standard 500-series specification and should work with any powered 500-series rack from major manufacturers. Ensure your rack provides ±16V DC and has a compatible backplane connector.
How should I clean and maintain the X-Amp 500?
Disconnect the module from the rack before cleaning. Wipe the front panel and controls with a dry lint-free cloth or a slightly damp cloth with water. Avoid chemical solvents, abrasive cleaners, or excessive moisture to protect the finish and internal electronics.
