What is a load box ?
Watts, ohms, how does it all relate?
A guitar amplifier is a two-way system:
an active part that produces and delivers electrical energy: the amp
a passive part that receives the electrical energy and changes it to sound: the cabinet with its speaker.
If the active part does not have a recipient, the amount of voltage will rise abruptly until a part gives way. In an amp, it can be the fuse, the power tubes or the output transformer that breaks.
With a cabinet, the amp is limited to its maximum power delivery through the impedance of the cabinet (for example 100w/8 ohms) In theory, saying my amp is 100w does not make much sense, but this would not be the first or only thing we say without any sense. We should say “my amp is 100w through my 8-ohm speaker”.
How to use a
This is where the
you can record silently to a soundcard or DAW
you can attenuate the sound level going to the cab if your
load boxis equipped with an attenuator system
you can play at every hour of the day and night
you can leave your cab at home for a gig, and send the signal of the
load boxto the mixing desk
