I've searched for the 2626 manual, nothing came up yet. One should be available soon.

the Presonus rep says it's backwards compatible with TB2 and works with the other Quantum interfaces. Starting around the 5:25 mark So there it is. Cool, thanks!

I'm still thinking of picking this interface Any more thoughts? Thanks! I'm sure this is just me, but man... what is with the wall-warts? I just can't take anything as serious gear if it's using a wall-wart. Presonus seems very fond of them. When the wall-warts fail in a session, and I have had this happen, then what? If your IEC cable fails, you grab another one, tho I've never had an IEC cable fail, which is another vote against wall-warts. To me, and this is just my opinion, wall-warts scream cheap gear and possible problems ahead. If you've never had a wall-wart fail in a session, you may feel differently, but anything with a wall-wart is a total non-starter for me. Again, just one person's opinion. Carry on. Kindly, -09

Kindly, -09 A wall wart is one of 2 things. Either an AC stepdown transformer, or a DC power supply. The DC supply could be "switching," linear, and regulated, or not regulated. They are replaceable, and there are "universal" power adapters you can use in a pinch. Just trying to throw some information out there that might help you.

Thanks monkeyxx, but after having one fail in a session, I'll never have wall-wart gear ever again. I know they're replaceable, but not so much mid-session, unless you stock wall-wart backups for everything you have.
Again let me emphasize that this is only one person's opinion and isn't meant to dump on anyone else's opinions or preferences.

LOL. Just teasing, but I also do have that.

I kind of like the wall warts because it gets the transformers away from the smaller electronics. If the internal transformer is improperly shielded or the shielding breaks down in any way then it can couple noise into the audio pretty easily.

what is with the wall-warts? I'm looking at the 4848 because of a power supply issue with the chassis of my Apogee Symphony MK1. The only way to get it repaired is send it it to Apogee. That is, if they still repair it since it is a legacy product. That's a path I don't really want to travel, and involves being without conversion for who knows how long. I hear you on the whole external power supply thing. It can seem cheap, and may very well be "cheaping out" in the case of some manufacturers who opt for low-quality supplies. I hope Presonus isn't one of them, since it is highly likely I will own some Quantum hardware very soon. If the supply is common across the line, perhaps I'll get an extra. You never know what might happen . . .

Those are all good points. Really and truly.
I'm just sharing my experience/preference/opinion. Maybe the Presonus wallwart is bulletproof and will never ever fail, but after having one go down in a session with the clock running and people looking at you like you're an idiot, and the session grinding to a halt all due to a failed wallwart, I'll never trust one ever again.
I'm not trying to change anyone else's opinions. The 4848 looks like a fine piece of kit and would be an option for me until I saw the wallwart jack on the back panel. Never again.

My Quantum uses a fairly straighforward looking "laptop style" "line lump" or to be more specific, a switching DC power supply that puts out 12 volts. Two prongs into the wall (no ground) and a barrel plug into the interface.
These are very common and not hard to find replacements or backups of. You just need to match the polarity on the plug, and make sure it's powerful enough (current rating in Amps).

Price wise, it's a very cheap bit of gear which may be helped in its price by using that external supply. FWIW I've never had proprietary wall warts fail but definitely generics have failed .
My question is , will they bring out new TB3 " pro models" (at higher prices) as this must surely have corners cut to come in at this price . Not saying it's bad , just saying id want something which competes soundwise with the.best. I see it as being pitched at musicians rather than audio engineers if you know what I mean.
Cheers, Ross

Apollos use "line lumps." Jeff Steiger and higher end lunchbox makers use "line lumps."
Quantum conversion is very good and quite neutral.
Quantum lacks direct monitoring, which can be a setback if you don't have a cue mixer set up.
Latency performance is extremely good, which matters a lot to some people.
It is one of the best interface options out there at the present time IMO.
I am an "audio engineer" as well as a "musician" and I use Quantum.
Just have to root for my team.

Kindly, -09 If the wall wart or line lump is all ready UL listed, the gear is instantly UL listed. Getting a piece approved by UL can take years. California law states any electrical appliance in a public building must be UL listed.

Thanks for sharing your thoughts! The specs for the 4848 have the maximum input and output at +18dBu where most interfaces are +24dBu. Do you find this a problem with connecting with analog gear? Any thoughts? I have an API console in front of the 4848. Pretty much the hottest output you can have. haha.
Chillax. Make music.
This computer geekery is wholy unsexy. I'll see you guys in the mic. console, and recording theory threads.
