Will I need a DI box?

[professorlamp]

So guys and gal(s) ?
Profire 2626 is on its way once my bursary comes through and I wanna be able to recording my amp and also a DI at the same time, can I do all this within the profire or am I gonna need a separate DI to split the signal?

ahah thank yur
so the answer be yes

You can either get a DI to split the signal or you can get a reamp box and go through the instrument input and then out of a line output to the re-amper to your amp.

I've actually been wondering if a dedicated DI would give you better results than the Profire instrument input, as on paper the Profire has better spec's than the DI's I was looking at:

Profire BSS AR-133 (£100) MTR DI-3 (£50)
Impedance 1Mohm 1Mohm 1Mohm
THD <0.0014% <0.005% <0.005%
Freq Res +/- 0.1dB 20-22K +0dB-1dB 30-20K +/-3dB 20-20K
Self Noise -108dB -105dB -100dB

So on paper at least, the Profire clearly wins on all aspects of performance, though obviously spec's aren't everything and really you would need to do a shootout to see how things sound. It does look like the Profire would capture the quietest most accurate DI signal though.

The "Inst" input is already a DI box built in, because it has an input impedance of 1 Megaohm.
But to record both direct signal and amp/mic/cab signal at the same time, you would need a splitter between your guitar and amp and the inst input.

Guitar > splitter
splitter > inst input
splitter > amp

Oh and make sure the splitter is active ! Passive splitter will send 50% of your signal to each destination... thats not a good thing.

Reamper can do this trick, as mentioned before.
I usually record DI`s with monitoring through reamp box.

 

[professorlamp]

So an active splitter, and these cost? and are they all the same or can you buy 'good' and 'bad' ones?
I just want the DI's as an emergency backup

Honestly, I'd say just buy a good dedicated DI Box.

[professorlamp]

well if im gonna buy one i already had my eyes on the redeye, and that's probably gonna be within my reach in a few weeks and i get the bonus of reamping

 

[AllanD]

Definitely the best idea.
