2hp stereo mixer & headphone amp PCB+Panel

$10.00

A simple stereo mixer — it has 1 plain-mono input, a second mono input that becomes a hard-panned left-channel when the third input, a dedicated right channel, is patched into. No pan pots, sorry, it’s 2HP. I actually designed it to go with a combination 4-way low-pass gate and stereo panning mixer that I haven’t gotten around to uploading here yet.

It has a reasonably decent headphone amplifier IC as its output stage, set to provide enough gain to drive my Sennheisers.

This is for the PCBs and panel ONLY. This line of 2HP modules uses a few weird parts (the BOMs are posted on github) so if you aren’t confident in your ability to source everything, just order a kit.

Note that this is nearly entirely surface mount. I used to be scared of it but nowadays I prefer it to through-hole because you don’t wind up with all those little metal legs that fall on the floor & then get tracked into a room with carpeting where they stick up and stab you in the foot.

The six things you need for successful surface mount soldering at the scale of my kits (0805 size components):

  • A decent soldering station
  • A lighted magnifier
  • Decent tweezers
  • A flux pen
  • .020″ solder
  • If your iron is a Weller, an ETA tip, or the equivalent for your iron

In stock (can be backordered)
