hey everyone, sorr for the noob question but i am looking for an attenuator and i noticed weber makes various wattage models.
I just grabbed a Marshall 2061x handwired , its rated at 20watts, and i was wondering if i have to get the 20 watt weber attenuator or something else, please explain.....
thanks

As the 2061x is 20 watts RMS (clean), you need to get a larger attenuator because when it distorts heavily it will go past 20 watts. Usually about double wattage (so for your 40 watt attenuator or more) is safe.

"If you are going to dime your amp out and attenuate it down to very quiet volumes then we recommend using an attenuator that is rated for twice the power of your amp's rated output.

If you are simply going to dial an amp up to where it starts to breakup in the clean channel and then knock it down a few dB so the club owner and the sound man are happy, then using a 50 watt attenuator for a 50 watt amp will be ok." - Attenuators

Thanks I too have been curious, and now I know.

I use a Reyes Audio Output Tamer attenuator I bought on ebay.

I think mine is rated for 50W. I'm pretty happy with it.
I've been abusing it with the haze and the 401 but it still holds together.
It can take a lot of beating from the amp.

I agree with M=A and the quote he gave issued by Weber. It is a good safe standard to go by. But the key to power handling attenuation is dissipation. Read up on the manufacturers descripition and specifications as to what the unit can handle safely.

Webers units are setup and designed with components to safely handle the dissipation as per unit model indicator, like a Mass 100 Watt can handle 100 watts of power.

Notice an attenuator like the Marshall PB100. The description states it can dissipate 150 watts.

So, read up on and understand the unit you are going to be using and how to apply it safely. It is always a "reliable" choice to have an attenuator that can handle a good bit more than the power rating of your amplifier.
