How I added an effects return jack to my Tascam Model 12

Hi everyone! I managed to modify my Tascam Model 12 to have an effects return that goes straight into the main bus.
Note that I'm not advocating that you do what I did, as it will certainly void your warranty.
By the way, I’m planning on releasing a deep dive on the pedal I showed in the video, which has features that no commercially available pedal has! Subscribe to my channel and you’ll get a notification when the video drops.

Hey just a heads up- I made a slight revision to my circuit- I changed the 22k mixing resistor to 470 ohms and changed the capacitor to a 47uf bipolar capacitor. I did this because I felt that the high end was a bit lacking and the circuit probably wanted to be driven by a lower impedance source. And it worked- audio quality improved as I hoped. Also: I don’t think I went into why I put the capacitor into the circuit in the first place. It’s because the data inputs are biased above ground, at about .74 volts, so you need the capacitor to avoid messing up the bias. I’ll put up an addendum video about this later if I have time. Thanks for watching!

You, sir, are a god-tier Model 12 user

[@StoryTimePlace]

Great job! Very interesting! You’re a daring guy!

[@cfa1101]

That is super cool, nice sleuthing and awesome mod.

[@johnjohnCDN]

Way to go! Clever.

[@pabloblue999]

Excellent mod, Great video. Would be interetsed to see vids on your home built FX pedals.

[@Hello-pl2qe]

Great video. Definitely interesting. Put more videos out!

Super cool. Ive been missing having a return. Thanks

TISINO 1/4 TRS to Dual 1/4 TS Y-Cable These Insert cables are used for creating a real-time effects loop by connecting a channel insert on an audio mixing board to an external effects processor with 1/4" unbalanced connections. Connect the TRS plug into the "insert" jack of your mixing board. The tip of the jack is a send (sending a mono signal to an external effects professor) and the ring is the return (returning a mono signal from the external effects processor back into the mixing board). This cable can also be used to split an unbalanced stereo signal into two unbalanced mono signals or to combine two mono signals into a single stereo signal.

wow remarkable undertaking! Your music is fantastic as well. Cheers!

[@kashphlinktu]

Thank you so much!

[@RecordingStudio9]

Well done. Amazing how one's will to get things to work, will find the way. One thing I would add in the future is a small stereo input level knob, replacing the 220K. You can set the Bluetooth to CH9/10 to monitor the incoming levels on the screen, just to be sure, and then switch back to the main bus.

Nicely done

[@4Ever4Track]

This is really cool.

[@objectsinspaceman]

Fantastic!

NICE! I'm about to upgrade my DP-24 to one of these, and I am DEF doing this mod! I still can't wrap my brain around how it works... even without the mod. So there are 2 AUX sends, and one goes out into your reverb... then where do you plug the output without your mod? another channel? if so, what is the use for the AUX knobs? I'm not thinking 3 dimensionally, I know.. but I will be back with some questions on the mod when my mixer arrives! like.. if you were to add a volume pot, how would you do it amd what value and such?

[@4Ever4Track]

The aux knobs could be used for mixing live and sending signal to stage monitors or in ear monitors. For recording they can also be send to a headphone amp to create monitor mixes for the performers. You can also use them to send to external effects and back to the M12 via the stereo 7/8 and 9/10 channels - that’s how I use them.

[@totalSLACK]

@@4Ever4Track I'm sad to say I actually kept my DP24 instead of getting the model 12.. the DP24 has 2 effect sends and alot more tracks and easily assignable inputs. i hope the model 12 doesn't have assignable inputs to channel, or I will regret not getting it 😬

[@4Ever4Track]

@@totalSLACK on the M12 it’s a little different but the result is the same. You could record all of your tracks from track 1. Instead of assigning input 1 to track 2 or whatever, you record it on track 1 and then “swap” the recorded track with any open track. So you can still record all tracks without changing your input.

[@totalSLACK]

@@4Ever4Track DOH! 🤦🏽‍♂️

[@wakinglife7065]

I’m trying out the radial extc stereo effects reamper - trying to take the sub signal and re-record them to 9/10 or 7/8. Just got it today so I have no idea if it works. Good thinking outside the box. I have had zero success with the y insert cable. No idea what I was doing wrong

[@martyamerica]

Nice work! Did you think about adding a pot to control the amount of signal? Also, when you were getting ready to drill the hole, I was thinking a glob of modeling clay or silly putty on the inside would catch the metal shavings. Just a thought. Thanks!

[@kashphlinktu]

That might work! I thought about a return level knob but I was lazy. I might add one later.

[@grambarefoot]

Any you could post the components needed to make this mod?
