    Hi, for years I've had the Rack Gizmo, since it first came out. With that, I've had a Marshall EL84 20/20, a few stereo racks collected along the way, and finally have 2 iso cabs loaded with greenbacks. So for the Rack Gizmo, I need to figure out what I'm doing wrong where only one channel is going through. Down below I will post what my current test setup is, and what we can do to identify why it may not be working. I do have quite a few TRS cables, in addition to insert cables.

    Front Input
    From Front - out to NS2 input
    Input 1-4 - from NS2 send
    Send 1 - into HM2ManyClones
    Return 1 - from HM2
    Send 2 - out to NS2 return
    Return 2 - from NS2 output
    *nothing 3 or 4
    Output 1-4 - into Input 5 with TRS canare (Ive tested it prior with just a mono mogami)
    Send 5 - Mono cable to Fulltone TERC (only has the one input)
    Fulltone TERC L/R Outputs - mogami insert TS to TRS
    Out 5 - In 6 w/ TRS Canare
    *Repeat Out/In w/ TRS until In 8
    Out 8 Insert TRS, to mono L/R Marshall inputs
    Marshall Outputs to each iso cab inputs

    Im thinking that when the TERC gets it, perhaps its changing everything to mono on one side, let me just quick test with the TRS cable, though could have sworn before when I tested it that it was still doing it, and the TERC is also set on stereo

    So my test just now, I shut off the marshall, and swapped the left and right, and the speakers swapped, meaning the outputs are both fine, seems like one of the inputs isn't recieving the information, I should check all the cables to make sure they are sending both signals through.

    The cable from Output 1-4 to In 5 needs to be TS on the Out 1-4 end and TRS on the In 5 end. Connect the tip and ring together on the TRS side. This converts the mono dry signal to stereo. The TERC might be converting to stereo itself, but if its loop is bypassed, you don't get that conversion and you will lose one side of the signal.

    That one doesn't look like it will work. You need something like below (ignore the pedal & PBC labels - the TS end goes to Out 1-4 and the TRS end goes to In 5). It's not something commonly available, but a custom cable builder like Best-tronics will be able to make it.

    Hi, so I was wondering, would this cable be 2 merged balanced signals to one signal, with resistors inside? Or is this cable one that is unbalanced to balanced?

    This cable is mono unbalanced to stereo unbalanced. We're using the TRS connector as a stereo plug (like headphones), not as a balanced cable.
