Get the most out of your mic preamps. Use your preamps as line-level saturation devices, or pad their output so you can drive them harder.

The L2P is a two-channel, balanced line/mic pad with two attenuation options. The -10dB setting is perfect for padding the output of mic preamps so you can run them hot without clipping your converters. The -30dB setting is a "line-to-mic" pad that allows you to run tracks directly from your audio interface or mixer to the inputs of your preamps.


  • Selectable -10dB or -30dB pads
  • Two channels
  • Excellent matching between channels for stereo operation
  • Line-to-mic pad

    Easy Rewarding Useful Build

    Very easy for a novice diy builder. Very useful tool.

    I grabbed this one on a whim but it's been really useful! I can now tack any of my preamps on any track in the box to get some nice analog variation. It makes for a really neat way of getting some subtle or not-so-subtle tonal shifts on anything. The kit itself is also supremely easy to build. Cheers!
