Hi all, another n00b question for the group.

I too am looking for an A/D converter to digitize quad sources (SQ records, Q8, and quad RTR). The Motu UltraLite mk4 looks like a good place to look for A/D conversion.

My quad components are currently connected to a DD 7.1 home theater receiver through its analog multi-channel inputs. With that setup I can't use my subwoofer with the quad sources. I'm hoping to find a device which could send a digital signal into my receiver to allow me to take advantage of my receiver's bass management capabilities.

The UltraLite offer ADAT optical out, but that's not compatible with SPDIF inputs in my receiver.

Does anyone here have any suggestions for hardware that can do what I'm looking to do, convert quad sources to digital via USB and output to a receiver through a digital input?

Any suggestions would be greatly appreciated.

Thanks!

LH

How about some updates for this thread? I am still using a MOTU but I've had it for years.

What is the best choice for today's Windows 10 x64 owner who wants to archive his Q8's and Q4's (and other stuff)
I am curious as to what's out there at what price point...

I put some suggestions in another thread, but to answer leeherman's question from 2017, the device won't send a sub signal to the receiver, a 4.1 file (or 5.1 file with empty center channel) created with processing in a digital audio workstation will do that. There are other ways. Have four full range speakers.

Well, members have used M-Audio and other interfaces, but when people PM me about what to use in 2021 I am afraid I have no clue? A lot of the stuff referred to in this thread is no longer made and hard to find.

That's why it would be nice to update this thread with more current recommendations.

I've been using a Behringer UMC404HD to record in old quad stuff--not 'pro' by any means, but it's cheap and gets the job done.

First thing: Line level is made to be very easy and forgiving for circuit designs and components! Literally the premise. The tiny trickle of a signal from microphones and phono cartridges are the critical difficult to work with signals that require extra effort in the preamp circuits and staying linear way down into the decimal dust.

In the last 10 or 15 years especially, just about any professional audio product aimed at studio use is going to have very solid line level ins and outs. The cheapest units are probably much better than ANY consumer AVR out there (although those too are going to be improved the same way).

MOTU may not have the reputation of Apogee or RME (or Weiss, Prism, and the like) but they will be closer to any of those than any AVR.

I think it's still true that the more boutique units' AD and DA converters perform better at SD than more budget stuff and pretty much equal their HD performance. You will NOT hear any degradation in audio at SD in an Apogee unit or the other more boutique units. You just may not be able to hear any difference in the newer MOTU products either. (I haven't bought any of their newer units. Still going strong with my two 838mk3 units. My Apogees are better sounding. Not night and day or anything but it's there.)

The bottom line is MOTU, Presonus, and Focusrite (the cheap ones of the bunch) are going to be an upgrade to most AVR output DACs as well as letting you capture analog inputs professionally. Shopping used for an older Apogee unit is another option if you want better too.

Rupert Neve of Neve mixing desk fame founded Focusrite if I remember correctly
