LX-3™ FAQ

If you don't see the question you had in mind here, feel free to enter it in the form provided along with your email address so we may send the reply directly to you. Thanks for your participation!

Can I use the LX-3 with a microphone signal?

No, the LX-3 is designed for line-level signals, and will not provide optimal performance with a mic-level input. If you need to split the output of a microphone the Radial JS2™ and JS3™ mic splitters are designed for this purpose.

Will the 48V from phantom power hurt the LX-3?

No, phantom power will not harm the LX-3. The transformer will block 48V at the isolated outputs, but the direct output will pass phantom power back through the input of the LX-3.

Can I use the LX-3 with unbalanced signals?

Absolutely. The LX-3 will automatically convert the signal to balanced audio at the isolated outputs. The direct output will mirror the input, and it will be unbalanced if the input is unbalanced.

Do I need power to drive the LX-3?

No, the LX-3 is completely passive, with no need for power.

Will the LX-3 fit in a J-Rak™?

Yes, the LX-3 can be mounted in the J-Rak 4™ and the J-Rak 8™, or secured to a desktop or road case using the J-Clamp™.

What is the maximum input level of the LX-3?

The LX-3 can handle +20dBu without engaging the input pad, and a huge +32dBu with the pad engaged.

Can I use the LX-3 backwards to sum three signals together?

You can, but you won’t have any control over the individual level control to balance the signals.

Can I use the LX-3 to split one signal to feed multiple powered speakers?

Yes, you can. This allows you to send a mono output from a mixing board to two or three speakers, for example.

Can I use the LX-3 to split the output of my guitar or keyboard?

Yes, although the StageBug SB-6™ might be a better option as it has ¼" connectors.

Does the PAD affect all of the LX-3 outputs?

It does, although there is an internal jumper that can be adjusted so that the PAD only affects the isolated outputs, and not the direct XLR output.

How do I adjust the internal jumper for the PAD switch?

To change the operation of the PAD switch, so it doesn’t affect the direct output, follow these steps:

  1. Use a hex key to remove the four screws that secure the cover of the LX-3.
  2. Slide the cover off the LX-3, and locate the internal jumper as indicated on the photo below.
  3. Move the jumper over to connect pins 2 and 3, this will allow the THRU output to bypass the PAD.
