Doepfer A-138j Inverting/Interrupting Mixer (Janus Mixer)The Doepfer A 138j is a 6HP, four channel mixer with an additional polarity mute switch for each input. In the upper position of the corresponding switch the inverted signal is used. In the center position the input in question is turned off (mute) and in the lower position the "normal" (i. e. non inverted) signal is used. The inverting of signals is used especially for control voltage signals (e. g. LFO, ADSR). But even for correlated audio signals

DIY, super easy to replace.
Fit 2018 crv. I like to change out my air filters before taking my car to the dealership for an oil change. Saves a ton of money to DIY. Easy to do perfect fit.

Works and is inexpensive
Used this for a 2019 Honda CRV, works and saved us a lot of money over getting it at the dealer. Easy to install.
