Bringing up the Level?

Discussion in 'Effects [BG]' started by Big Benner, Nov 30, 2005.

  1. Not sure where to post this, but here's a situation - My band will be playing a medium venue with little but vocal PA support. We're not a loud band (2 guitars, keyboards using 1x12 combos) but we are a original alt. rock band so we're no jazz trio. There will be 2 1x12 monitors and 2 1x12 mains for the vocals and a little of the guitars and keyboards, perhaps a smidgen of snare drum. In this situation in the past I have placed a SM57 right inside the Kick Drum (in between the blankets), run a line into a Behringer Ultra Gain Pro 2200 mic pre and sent that signal into the side chain FXs loop on my SWR SM900 adding a little more low end thump through the 1x15 and 2x10 speakers. Worked beautifully and just made the low end of the entire band sound large and thick running through a proper bass rig instead of the 1x12 mains.

    My problem is I don't have access to the Behringer preamp. What I do have is a newly aquired Presonus Firebox - I don't want to use this until I learn more about it. So instead I'm thinking of running a XLR to 1/4 inch adaptor from the SM57 into a BOSS LM-2 Limiter pedal. All I need is a little gain from the mic going into the FX loop - anyone think this is going to work?

    the XLR is a balanced connection, so you need a balanced input to make it works, and the BOSS pedal doesnt have one.
    you also need a pre amp cause the mic level is very low compared with the level the FX loop needs to operate....

    you`ll need a pre amop there for the mic
  3. Just to clarify that, it'll work ok, it just won't work as it's intended. You loose 6dB just by running a balanced source into an unbalanced input, then, like dadodetres says you'll need a lot of gain (not just "a little") to make the mic come up to a decent level, but I figured you kinda knew that already.
