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)

    Great product!

    Good for beginners, easy for any intermediate builder. Works perfect to send signals to a mic preamp from my DAW

    Good for taming down vintage preamps

    I have an old tube preamp that hits my ADAT interface pretty hard, even at low volume. At -10dB I can bring my main volume up to high noon and still have -3dB headroom on my faders without sacrificing tone. Very transparent.

    Secret Weapon

    This is awesome. It unlocks so much in mixing and even production. I love the fact I can send my 808 into any of my pres and gain some wonderful flavor.

    Works exactly how intended

    It does exactly what it is supposed to do! Setup and the build were super quick and now it lets me run stems through my Phoenix Audio Ascent Two-EQ without any distortion since even with the built in pad it was not intended to take line level input. Patched right into my patchbay with no problems at all. Super glad I bought it.
