1073 DPA as line in - a good thing?

1073 DPA as line in - a good thing?

I've got a chance to buy a 1073 DPA at a low price. The quality of its mic ins goes without saying; however I do little live (mic) recording, but stacks of line-in recording (synths, etc).

What kind of 'Neve-mojo' (if any) can I expect using the line-ins? This unit is a step up from what I'm currently using, so the wonders of transformers is a mystery to me - the flyer for the unit states;

"Gain from the Line input is applied in the 2nd class A gain stage and is output through the same class A transformer coupled output stage as the Mic In"

Obviously I'm going to use my ears when I demo the thing, but some pointers from older, wiser minds would be appreciated!

Thanks

Use two DI boxes and the Mic input when recording synths etc.

Compare that to the line input and make your choice.

We have the DPD here (same analog circuitry).

If you like what this thing does at all, then you're going to like the line-ins as well as the mic inputs. It's a beautiful thing! thumbsup

I use 2 DI Box into the micpre. Works great.
So I never bother to the line ins, but I will give a try.
This is a serious unit. If you can, don't think twice. Get it.

to everyone who took time to reply - thanks

Never even occurred to me that a DI into the mic in was an option - you live and learn.
Cosmonauta - if you get a chance to post your thoughts on the DI > mic in versus line in sound, I'd be really grateful.

but I don't think I really need that much convincing to go for the unit....

This thing has always confused me...in this way the DI box is used to turn line level into mic level. The preamp then turns the mic level into line level again

Have always thought a DI box turned high impedance electric guitar/bass outputs into mic level, which is then turned into line level by the mic pre.

Does this mean that you, in theory, also could take the output of a preamp (also line level!), feed it into a DI box and then into the mic input of a second preamp?

Sure you could, but i can't imagine doing that in a recording scenario...

Hah! I bet a new trend starts up: when recording mono vocals with your high end dual pre-amp you DI the output and go into the second unused pre for twice the mojo!!

Hi Mattsson
Yes you can if you want.
The point is that the mic input has the transformer based input on the DPD/DPA.
The DI box presents a signal it works best with being a mic input.
If you drive this transformer based mic amp hard it does "overload" in a very pleasing way on some audio.
Try it on a drum sub mix....

its not about level, its about impedance. i don't believe the output of a guitar and a preamp are the same impedance. i believe the guitar is a higher impedance signal, but i could be wrong.

Yes, that's correct. Guitar signals (from passive guitars, that is) are high impedance (in the vicinity of 1m ohm) and produce a signal level that is typically about -30dBu.

Mics are low impedance (600 ohms, 1.2k ohms etc) and lower in level - sometimes as low as -60dBu.

Line level may be low impedance, but over relatively short runs is now generally terminated with impedances of 10 to 20k ohms, sometimes higher - and at a nominal operating level of +4dBu (not even going to mention the pro-sumer line levels, since we're in the High End forum ).

did anyone ever come to a conclusion on whats better, the line in or a DI

Ive been recently running my synths through the line ins on the dpa but through the mic ins on the API 3124.

i got a overly compressed sound when running the synths direct into the mic in on the 1073dpa.

would i also get a better sound if DI ing the synths before going into 3124 mic ins?

i run a lot of drums out of my synths too.

Thanks

If this is hooked up to a patch bay, how would one go about using the di box into the mic in and using the MIC in when there is a need. Doesn't seem to convenient

The same as most other mic preamps? How is patching a DI in any different to patching a mic tieline to it?

Here I'm, 9 years later from my last post on this thread... and Neve 1073 DPA stills my favourite vocal mic preamp.
And I still don't bother about it's LINE INs. Though it's available via my patchbay.
Just the other day I tried to run some signal through it... not sure if there's something wrong with my patchbay connections or if my unit is defective but all I got was a VERY low unusable signal from one channel and silence on the other...So I still can't comment about it's Line Ins.

Uhh no.

The DI can be a separate input into the patchbay. So you can switch it on an off in the front end. To my understanding, please correct me if I'm wrong. If I didn't want to use the DI with the neve dpa I would have to go behind and disconnect the DI box? That was my original question

This doesn't make any sense.

I think you are missing the point. A patchbay would have mic ties on the top row, and inputs to the preamp on the bottom row. How is plugging a DI into the mic input on the bottom row any different to patching a mic into it? It's literally the same operation. Why would you be going behind the unit and disconnecting cables if you have a patchbay - that's what they exist to stop?

Ahhhh so If I don't want to plug into the direct box on my patchbay I can simply bypass it by going straight into mic through the patch bay front. Okay wow, cool sweet I'm so glad I got into this patchbay thing. Still so much to learn
Which di box do you use preferably rackabke
Old 26th January 2015

Yes - keep it simple! I use the BSS AR-133* and just use an XLR to Bantam cable to plug it in to the front of the patchbay - no need to rack it or hide it away behind the rack.

* Other more audiophile-friendly DI boxes are available.
