DIboxes lose resolution on XLR out when using the "THRU" out (advice for recording)

Well, the phrase is not "losing resolution" exactly.

Anyway.... when using the "THRU" output to your amp, DIboxes tends to split that signal to both outputs, wich results in a weak signal on the XLR output, right ?

If i'm using my DIbox for recording porpuses, should i unplugged everything else and let the full signal go through the XLR output, or what ?


I'll work on my english, i promise. :D
 
Its there in case you want to split the signal into 2 tracks.

Called reamping...

What happens is your mic you amp the way you normally do & then run a line using the "thru" (all the thru is going to record is the dry signal from your guitar)

After tracking if you dont like how the guitar sounds but you got a great performance you can run the "Dry" signal that came from your guitar back out to the amp from the mixer and adjust mic placement, reverb, etc and rerecord without having to play the part on the guitar again.

I hope this is what you where asking :D
 
Ok but, let's supose for a second that your going to do a serious guitar recording.

Would you work with the XLR signal, knowing that it has half the resolution, when using the "THRU" output ?

or would you work with the FULL signal "NO SPLITS" and play with it, in post?

I would work with the XLR signal and I wouldn't care about the resolution from the thru output because I am going to make use of the pre on the mixing board to get the "dry" signal of the guitar up to par.

That way if the track was screwed up from all the reverb that the guitarist put on that particular track during tracking.

After that said guitarist leaves I can go back with the dry signal set the amp reverberation delay or whatever to what i need it to be so it sits right in the mix.

It is not half the signal. The power doesn't get split up. In a passive DI, the signal is sent to a transformer and through inductance produces a signal on the other side of the transformer. With an active DI, you have less to worry about.
 
ok but the signal is less STRONG on the XLR output , when i'm using the THRU output too.

I mean, when i'm not using the THRU output, the signal gets hotter on the XLR output.

What is the correct way to work with, if i'm planning to use my own effect processors in post ?
 
So turn up the mic pre. You are worrying about something that doesn't have any real bearing on anything. Just record and have a good time.

Maybe, maybe not. As always, the best way to tell is to try it both ways.

The term "split" is misleading. It doesn't work that way.

What happens is that when you use that thru jack and plug into your amp, the impedance of the DI is put in parallel with the impedance of your amp. This lowers the impedance the instrument sees.

The signal is never "split", it is just run into multiple inputs, with parallel impedances. If the inputs have high enough impedance, no signal loss happens, or at least it is minimized.

The same thing happens when you use any "splitter".

Any loss of signal level is due to your instrument driving a lower impedance load. Driving into a too low impedance will affect tone.

The higher the input impedance of amp and DI, the less loss there will be.

So, whether you get any loss or not will depend on your DI, instrument, and amp.

For the most part, I'd be surprised if it was more than few db. Much more than that, and your tone would start to suffer as well, and you'd notice that for sure.

If it ain't hurtin' your tone, I wouldn't worry.
 
I have a "Radial JDI". I'm using it with "THRU out" for monitoring, but it cuts from -3db to -18db on XLR out, that's a lot.

It's easy to say that, if you have a noise floor of -306db, wich i guess is your case. :D

But i don't know if i'm broking the Laws of Physics by amplifying a signal about that weak.

I'm guessing you are playing electric guitar or bass, with passive pickups. That would account for the extreme loss, as the JDI (a kick-ass DI) is passive, and has only 10kohm input impedance.
 
Unfortunatley, you need an active DI for those situations.
