L2P Passive Line Attenuator Kit

$50.00 USD

  • Full Kit
  • Step-by-Step Guide
  • Supported
  • Beginner

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.

Features:

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

Specs
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)

 

Kit Contents:

  • Amphenol XLR jacks

Mostly Great

I enjoyed this build. All the components were well-packed and to spec. My one star deduction is due to instructions, which I think could benefit in two ways, and a small materials qualm:

1. Mainly, I didn't seat the second output XLR jack flush to the pcb. This happened despite, and maybe even due to, following the instructions exactly, which state to flip the board over and leave it lay propped on an angle. The subsequent difficulty was that when I finally tried to attach the output side face plate, one of the mounting holes on the XLR cup was very off. This difficulty was compounded by the fact that the screw path on the XLR jack is not threaded, but is threaded by the screw itself upon insertion, so any attempt to screw into it will not only give zero indication when doing a 1/4 turn reverse turn to seat, but can create problems in the event that you do manage to thread it crookedly. So I firmly feel that an improvement to this critical portion of the assembly guide give this sensitive step the extra attention that can prevent needing to reflow the jack.

2. A very minor point, but I don't believe that the type of soldering tip that is best for this job is suggested. Granted, the one I used was close to what is included by default in many kits, but I had to swap out my chisel tip that I use for guitar pots. This is a smaller nit pick, but given that this is a beginner's kit, I'd hate to see someone heat up their iron and try to force their way into some of these joints, which are honestly fairly tight, especially on the XLR and toggle switch pads.

3. I'll add, if I'm being totally honest, that for $50, the tolerance of the case could be a little tighter. The body is slightly concave, which creates a ridge on the edges where the end plates connect. To the hand and eye, this creates imperfections that are not easily solved with readily available tools. It's not terrible, but it's not stellar.

For these reasons, I offer the constructive feedback instead of a full five stars. Thank you for your consideration.

Great build

Really enjoyed building this and the other 2 in the beginners kit. Perfect for me being a first time builder. Waiting for the ribbon mic rm-6 when back in stock and the never clone after the mic builds!!

Great first build

I had no issues with the build. The instructions were clear, etc. After a few sessions with it, works as expected and the sound is as transparent as I would want. If anything, I'd like to see an option for TRS outputs but everything is great.

Excellent build

The contents of the kit were well sorted. All of the instructions were very clear and concise. I tested each component before assembly with no issues. Assembly took 30 minutes plus testing which total time was one hour. Test was very quiet, no added noise. The tone of the amplifier sounded uncolored by the L2A. Through a SSL2+ interface. Excited to get into the next kit.

Fun and useful project

This little device is quite useful around the studio, fun little project, high quality parts, clear instructions. What else can you ask?
