TBM1 True Bypass machine

The TBM1 True Bypass Machine is the perfect solution for those looking to switch easily between 3 stereo processors. The TBM1 is fully passive relay-switched, designed straight-forward and delivers exceptional transparency in your setup for an affordable price.

The TBM1 comes with 1 stereo input and output, along with three stereo inserts, all equipped with gold-plated Neutrik XLR connectors in a sturdy 1u 19-inch rack-unit. The 3 inserts can be enabled or disabled by the push of a button and insert number 1 and 2 can be swapped in order. Optionally it’s even possible to connect an external controller (DIY, info provided) with your own switches so that you can leave the TBM1 out of sight while still having easy access to control all inserts.
