SPL hardware with a DAW

Postby Pitchfork » Sun May 14, 2017 10:08 am

A quick simple question! I am looking at an SPL Vitalizer for my mixdowns (hardware not the plug in) and wondered on the best way to connect?

I am upgrading my Soundcard, so do I need one with at least 4 in/out, so i can put the SPL on sends returns for different channels and then on the final mix render?

Or... do I just put it on the output of the Soundcard > SPL > record to another Computer/DAT/Recorder?

Is there a simpler way to do this so its always connected on ins/outs or sends/returns so i can use it on various channels?

Thanks for any help

The easiest and most versatile solution is to acquire an interface with sufficient spare I/O to allow the SPL unit (and any other outboard) to be permanently attached. You can then patch the unit(s) into the signal path as needed using the DAW's internal routing facilities.

Yes, you need an interface with many line ins/out and good converters since the signal is going in and out of the box potentially many times.

Back in the mid-90s a colleague and I sat down and transferred analogue audio back and forth between two Sony professional DAT recorders (a PCM7030 and PCM7040), specifically to create a demo of how many paths through good (but not esoteric) A-D/D-A converters it took before audible degradation was heard.

Most people couldn't hear any losses at all until at least 35 generations. In really good monitoring conditions with experienced listeners, it was possible to hear some very subtle losses after 12-15 generations.

...And converters have become a lot, lot better than those since then.

So a quick loop out of a decent interface and back once or twice really isn't going to trouble anyone... especially since the whole point of going out to external hardware and back is to modify the sound anyway!

Good to know since I use for the moment a RME Multiface I and I find myself doing these loops a lot :)

Thank you for the replies on this, are there any smaller USB Interfaces that spring to mind, say 4 in 4 out to add a peice of hardware like this?

I was thinking of something very cheap and basic like an Edirol UA-25ex as it has Optical, MIDI but is only 2 in 2 out..
Also I'd be using (and swapping) between Mac OS X and Windows 10 for compatibility

Depends what you mean by 'cheap' Pitchfork but the NI KA6 runs out around £165.00.

Very compact and beejew! Totally bus powered so no rat to add to the clutter.

The top knob makes it a nice monitor output device as well.

Plenty! Focusrite, Presonus, Steinberg, etc - just head to Thomann to get an idea.

One small note that can be helpful, depending on your physical setup: many 4x4 interfaces have two i/o in front and two in the back, which works fine but is not so nice when it comes to cable management. An interface with back inputs/outputs only can be a bit more neat.

The KA6 has 3/4 in and 3/4 out on the rear.
