Model 12: Using A Hardware Pre-amp - Connecting and Configuring

[tommyzai]

Would someone kindly list/illustrate how to connect the following?
I am confused about cables, settings, and phantom power (thinking double 48v is probably not good).
Note: I haven't used hardware since the 90s. I'm very rusty.

1. Condenser Mic
2. Hardware Pre-Amp
3. TASCAM Model 12

Thank you!!

The Model 12 has built-in Ultra-HDDA mic preamps that can provide +48V phantom power for condenser mics. Are you sure you need to use an external mic pre-amp?

But if you do, connecting depends on the external pre-amp output: mic level or line level; and the type of output jack: XLR, TRS, or TS. Line level output must go to the Model 12 TRS combo line level input jack. The external pre-amp supplies the phantom power.

Hi!! I'll be using a Summit Audio 2BA-221 (pic attached). It has XLR at +4 and 1/4-inch at -10 and there's also an insert. I'm wondering if that insert allows me to connect Model 12 to this pre--amp using a simple TRS Cable. If not, can I use the XLR out to the XLR in of the Model 12 without using Model 12s phantom power? Some units seem to disengaged the +48v when using a TRS and engage with an XLR. Any thoughts are appreciated.

Even with no knowledge of the S/Audio gear, it's safe to say the the "insert" is for side-chaining an external unit (EQ, comp'r, etc) - not for signal access (though surely someone's tried it...).
If I were me: I'd go directly from the mic to the M12's inputs (using its' 48v)...unless there were specific reason/s to prefer the outboard pre.

In any case: all of the pertinent info is in the gear's manual/s, and probably all over this forum too. RTM, learn/know the block diagram, read the Sticky Posts in the forums here, and learn to use the search function. You'll be able to help yourself much better than others will be able to help you.

Good luck!

I will be using an external pre amp and compressor. My research indicates that I have options....

1. Mic via XLR to preamp to Model 12. Compressor connected via TRS insert. Would TRS cable be best into M12 from pre in this scenario? If so, will 48v be automatically disengaged?

2. Mic via XLR to preamp with compressor side chained/connected directly to pre, then out of pre and in to Model 12.

Any thoughts on cables and configuring Model 22?

Scenario 1 will totally work. You won't NEED the 48v supplied by the M12, 'cuz the preamp will supply it (assuming it's turned on!). And a TRS from preamp to M12 would be a good idea - assuming your preamp's output IS a TRS connection...otherwise, just go w TS.

Scenario 2 sounds like the same setup, just different wording...isn't "side-chaining" what the insert circuit is FOR??

 

[tommyzai]

Thanks. The difference between the two scenarios is how the compressor fits into the chain. I can either have it inserted into preamp or inserted into channel 1 or 2 of M12.

Any thoughts on which would be better?

Aha! Subtle but significant difference.

I’m not sure it’d make a hyoog difference where you inserted the compressor…I guess I’d probably say do some test recordings & see if you hear something that suits your preferences.

If it matters - my instincts say earlier in the chain is better (insert in preamp).

But I’m spitballing…there’s guyz here WAY smarter/more experienced than me. I haveta remember which way the pointy end of the git’r goes every time I sit down to play…

Thanks, Shredd
I'm leaning the same way . . . connect the compressor to the pre-amp. My thinking . . . there are units that have both, so maybe I'm sort of creating my own pre-amp/compressor by connecting them. Yet, if someone much smarter and wiser than me sees a problem with this, please . . . .
