I Have a 4 Ohms Amp - Can I Use a Captor X With it?

I Have a 4 Ohms Amp - Can I Use a Captor X With it?

Yes, it is possible but you have to be careful.

The speaker output of a tube amp is designed to be matched to one (or several) specific load(s). A 8 ohms speaker output is supposed to be connected to a 8 ohms speaker or load box. In some situations however, you may not be able to match the impedance of the load to the impedance of the speaker output, for example if you have a 4 ohms amp and wish to use the Captor X 8 ohms. Connecting the two leads to an impedance mismatch.

NOTE: It is absolutely impossible to use the Captor X 16 Ohms with a 4 ohms amp!!

The impedance mismatch may or may not be a problem, it actually heavily depends on the amp's design and the way you use it. It is generally accepted that a small mismatch is not a problem if you play the amp at low level, but this isn't a general rule. As a result, we can't guarantee that a mismatch will always work for you. It's always best to go for the right impedance if possible.

That being said, if you want or need to mismatch the impedance of the amp and load, we recommend the following:

  1. Play your amp at low level, at least at first
  2. Monitor the behaviour of the amp, the tone coming out of it, the color of the output tubes. If anything seems wrong, stop playing
  3. In short, follow even more carefully the Recommendation on the proper use of a loadbox with a tube amplifier that you'll find in the user manual of your Torpedo Captor/ Captor X
