The manual reveals the secret sauce: Did you know you can use this as a 24-channel inline monitor console? Did you know the "Aux B" section can be flipped to act as a secondary stereo bus? Unless you read the original TASCAM documentation, you’d probably never figure out the shift functions on the mute buttons.
If you just bought a used M-2600 MKII (which, let’s be honest, usually comes covered in studio smoke residue and mystery coffee stains), the physical manual is probably missing. Do not sleep on finding the PDF.

If you have a patchbay wired to those outputs, you can accidentally send 48v to your compressor inputs. Read the "Current Limiting" section. It matters. The manual reveals the secret sauce: Did you
Unlike modern digitally-controlled preamps, the M-2600 MKII has trimpots for days. If you want your stereo bus to actually sound centered, you need the calibration procedure.

One of the most common forum questions is: "How do I get direct outs post-fader on the M-2600?" If you just bought a used M-2600 MKII
Released in the mid-90s as the centerpiece for project studios that couldn’t afford a Mackie 8-Bus but wanted more mojo than a Behringer, the M-2600 MKII is a fascinating hybrid. It is part broadcast workhorse, part analog summing monster, and 100% heavy.
Since TASCAM no longer supports this console officially (vintage status, baby), you need to hunt for the PDF. Search for:
