    I was wondering anyone was familiar with the BBE Bmax preamp. What I need to know is - What is the output line voltage? I'll be running it through a QSC PLX-2402 at 4 ohms. The input sensitivity is 1.3 volts for this amp at 4 ohms.

    I've emailed BBE and they've given me no response - and it doesn't say on their website.

    Thanks!

    Well the reason I'm asking is - If the line voltage doesn't match up properly to the input sensitivity of the amp - The preamp will never kick the amp into full wattage. I learned this from Bob @ QSC.

    Shouldn't be a problem. BBE preamps have enough output voltage capability to drive every pro amp that I know of. You'll be able to turn the amp gain down pretty far and still drive it fully.

    Well, while we're at it - What about the Sansamp RBI rackmount pre?

    Thanks again in advance!

    I actually noticed this too. I have my power amp at about 9 o'clock (second click), and the gain and volume of my preamp at noon. When I need an extra kick I take the power amp to the third click (its a rotary knob) or 11 o'clock.

    I don't know for sure; their Web site says that it has selectable output levels, so that's an encouraging sign.

    E-mail Lloyd Schwartz at Tech21, describe what kind of instrument you have and how you play, and ask him if with that driving it, the RBI can put out maximum levels of at least about a volt and a half. More than that is fine, too. He can tell you if it's feasible.

    I've got an email in with him - also, I've checked their website for further details.

    Thanks for your help!!

    No, not yet actually [​IMG]. I never heard from them and I kind of forgot about it - I'll e-mail them one more time I guess...
