When you play your amplifier through a Torpedo product which embeds a reactive loadbox (Torpedo Live, Torpedo Studio, Reload, Captor, Captor X), you may hear the sound of your instrument coming out of the chassis of the device, like there were a small speaker inside the unit. This is perfectly normal and there is no reason to worry.
This sound is produced when the power coming from your amp passes through the coil of the reactive load. This creates a magnetic field, which makes metallic objects vibrate (the metal enclosure, the wires in the coil itself, etc.). When these objects vibrate, they emit sound. Because the signal causing this is the actual output of your amp, you can actually hear your instrument.
You may also hear similar sound coming from your amplifier, specifically from the output and/or power transformer. Such noise has always existed in your amp, but you have never heard it, simply because it is normally outweighed by the sound coming from the companion loudspeaker.
This phenomenon is not always audible and is dependent on the amount of power coming from your amp and the type of signal sent to the reactive load (for example, distorted sounds are usually more audible).
There is no simple way of getting rid of this sound. With the Torpedo Studio, you can set the loadbox as "Resistive”, but with the other Torpedo products - or if you want to retain the reactive load of the Torpedo Studio - the only way to reduce this phenomenon is to lower the output level of you amplifier.
