I'm not interested in going into a computer and doing all that rigmarole...
Fair enough there. Although any of the old analog formats are literally magnitudes more of both fiddling around and expense.
I'm coming from the perspective of getting as close to the studio master as possible with no alteration or reduction of it. The computer offers happiness and light there for me. Someone else might be more interested in the user experience of old gear more than chasing the full sound of the recording in question. If that's your thing, I have no argument or comment. I'm also interested in preserving anything old (and possibly damaged) to the highest standards. I have interest in the old technology along those lines. But not the use experience.
All of the ones I've seen are, at best, stereo audio and NTSC/PAL video. No multichannel anywhere. If you know of any, I'd really like to see what they are.
It IS harder to find a budget interface with 6 analog outputs. Most of the budget models have 2 and then it goes up to 8 or more and a price to match.
These are a couple more budget (but still very pro and much higher quality than most consumer electronics) audio interfaces that have at least 6 analog outputs:
Focusrite Scarlett 6i6 $260 new $150 used
Presonus Audiobox 44vsl $200 new $120 used *** Sorry, this one only has 4 analog outputs! Would do quad for you though.
Moving into the "If you have to ask..." territory:
Apogee Element 46 $900 new (6 analog outputs)
Looks like you can get an Apogee Rosetta 800 (8 analog outputs, 8 analog inputs + some digital I/O) for $500 used. That's a pretty sweet price for this level of DA and AD converters. This thing went for over $2000 new!
Not even going to look at Prism right now...
Let's face it, vinyl was great in the '70s, but this is almost 50 years later. 16 bit/44.1kHz will be more than adequate for the bandwidth and S/N of those beloved old records.
Strongly disagree. No reason not to use 24 bit and every reason to use it! Consider that generation loss adds up. (Ever try to make too many copies of something?) Anything above 60KHz should be lossless for music program (assuming the AD stage was class A and on point if capturing analog). The nearest standard sample rate is 88.2k and the more common release format is 96k. If you're doing something like transferring vinyl to digital, the effort is in the prep and the real time analog capture. Would be foolish to set a switch to lower quality. Easy to click a button and make the lo res copies for your phone after the fact as an extra.
But again, I'm not after the experience of using the equipment. I'm after preserving the audio to the highest level possible (and exactly what came off the mastering desk whenever possible). I have respect for the old equipment and it's abilities that were successful but I'm very much not interested in preserving the artifacts or quirks. And again, I have no argument with anyone who is. Different goals.
