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 
Input Impedance 8.1k/5.5k (line out / mic out)
Output Impedance 2.7k/150
Attenuation 10dB/30dB, selectable
Noise Floor -113dBu/-115dBu (line out / mic out)

    Essential tool to get out of the box!

    Using for post-console/pre-converter mix

    Originally built it for re-amping through my CP5 preamps, but found out that the pads on the preamps are sufficient. So I thought I didn’t need it, but recently discovered it’s usefulness between my console master-outs and my interface while recording the 2-track back into the computer.

    My Midas F32 can handle insane master-buss summing levels, but the output is far too hot for my Quantum4848 converters. So I run the LP2 between the two with the pad set at -30 dB. This allows me to slam the master buss of my console while keeping all faders at unity without blowing my converters away.

    I’m glad I found a use for it, and it is VERY useful for this hybrid analog/digital recording set up.

    Thank you Peterson.

    Easy Rewarding Useful Build

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

    Unlock Your Potential

    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!

    Easy to build. Works flawlessly. Dumbing down a balanced signal with ease. Cute little box too. I’ll be keeping this forever. Thanks folks!
