LM II biamp?

    Just wondering if there are any issues running my LM II head with both inputs (XLR and guitar lead)?
    I want to send low freqs from a sansamp (treble wound down) into the xlr, and high freqs from my sansamp RBI unit with compression into the standard input.
    Are there any issues? Could I damage the amp? Is there a better way of biamping with the gear I have?

    That's not exactly a "standard" way of biamping but you should have control of the outputs from both Sansamps.

    Biamping is typically running two amps with different parts of the same signal source and running that into seperate speaker cabs. Like running highs to one channel of a stereo amp and lows to the other channel.

    You'll be running the equivalent of multiband compression... with one band off;)

    You can also run an input into the rear effects loop.

    From reading the website, they are saying you can plug a mic into the XLR input (made for Upright basses) and plug a bass into the 1/4" instrument input and play use them at the same time.

    No. You can plug three instruments into the LMII at the same time (front 1/4" and XLR, rear 1/4").

    I have used my LMII with the 1/4" input and the XLR input at the same time on several occasions without issue.
     
  8. On a side note FYI to this thread, the new LMTube and LM800Tube (supposedly shipping within a couple months to the US) have a dedicated volume control for the XLR input, and the XLR input was upgraded to a combo jack, allowing 1/4" input (along with some other goodies like a blendable tube pre section, mute switch, fully featured DI with level control and pre/post switch, a new power amp safety limiter that should be more transparent when pushing the amp, and some slight revision to the treble and bass control center frequencies).
