    Hi all,

    I'm considering to buy Darkglass Microtubes 500 and a Markbass Traveler 151p (8ohm) and while I was reading the Microtubes 500 datasheet, I've seen the following message :
    Can it damage the cab or not?

    Yes it can damage your cabinet. But that's true of any amp.

    Keep in mind that the 500/750 watt rating is for a 4 ohm load and you have an 8 ohm load, so you will get overall less power. Just use common sense with the volume knob. If your cabinet starts to overload, turn it down.

    Thanks for the information.

    I've just called Thomann and it seems that the 750Watts peak at 4 Ohms is about 385 W at 8 Ohms.
    So if the M500 master is not set to the maximum value, this should be ok.

    Except that the master volume position has little to do with maximum rated power.

    So which knobs drive the power?
    I assume that the amp doesn't drive continually the max power.

    All controls factor into how much output power is delivered, as does the input signal strength.

    Signal strength depends on the pickups, the bass setup, the electronics in the bass and very much the playing style.

    Right, and likely playing style is the most underrated factor how much of sub harmonic "transient noise" is really deliverd to a cabinet if there was no "decent" HPF present that protects the cab from potentially harmfull (transient) sub harmonics.

    Ok, thanks for these explaination.

    I was not aware that the input level and the playing style could have influences on the power delivered.

    After discussing with Doug from Darkglass, it seems that the Microtubes 500 can fit with a 400W/8ohms cab.
