Maybe it'd help to just think of the Alesis analog input as a Mic/ Line amplifier.Īnyway, it's all good, if you only want a line amp between the outboard pre and the ADC, there are plenty of cheap interfaces with 4 analog in (2 mic/ 2 line), but I would not be surprised if the diff is negligible. My guess is that the OP doesn't want redundancy in his signal chain (running a mic pre into a mic pre= bad gainstaging) and that makes sense but IMO the higher impedance/ no DC on the 1/4" line input addresses the more important issue. I'm not claiming to know the answer and find the issue to be a lot of fuss about nothing. mean when they say "line input bypasses mic pre"? Maybe all that it means is that the impedance is higher and that phantom power is disconnected on the 1/4" line input. makes me wonder what the customer service folks at MOTU/ Focusrite etc. I recall similar confusion regarding the Saffire 40.
Claims are made regarding the MOTU 896Mk3 Hybrid in this thread (and elsewhere, some folks cite conversations with the manufacturer to bolster their claim) yet one look at the manual states "For line level quarter-inch inputs, turn on the pad." (the same pad that Motu uses for all the inputsources, line, mic and Hi-Z) and schematics can't be found. There seems to be a lot of contradictory info on the web regarding which interfaces allow for the mic pre to truly be bypassed (as in removing it from the circuit in its entirety). YMMVīTW, the $250,000 console I spend a lot of my time on has a mic/line amplifier, everything runs through it, line, mic and High Z, so what? In that case, don't bother with a budget interface to begin with. "Bypassing the micpre" is some quest for tonal purity. Meeting these criteria qualifies for "bypassing the micpre" IMO unless IMO the important thing is that the impedance is right and that you can't accidentally put phantom power on unbalanced output devices like keyboards or micpres with insufficient protection against DC voltages (yes, they do exist) How much total gain is on tap and is it from one stage or two stages of amplification?īut the more important question is whether "bypassing" a mic-pre and running it into an equaly cheap line amp vs running into a mic-pre with pad, set to the correct impedance and to unity gain will make much of a difference. The line in on it does not pass through the mic pre.ĭo we know that the line input switch on the Alesis inserts a pad or is it possible it re-routes the signal straight to the second stage (the line amp). My 4 channel lexicon Omega from 12 years ago cost next to nothing yet has 2 mic pres and 4 line amplifiers. Unfortunately I can't find a schematic for this model but I wouldn't automatically assume that a cheap interface can't do this. The op knows he can use another preamp, thats not the question. They would use one input or the other and then have no preamp.Īre you saying that some preamps disable the preamp stage when someone uses the 1/4 input ? Line/ VS Instrument ?Īlesis states that on this model you can connect EXT devices via the 1/4 or the Inserts but basically brags that they are all compatible with the on board preamps. And we don't want it to, otherwise the user would have a useless tool in front of them if they did not own another preamp. The 1/4 Instrument/Line does not disable the preamps. It's a reasonably low cost combo, interface/preamp. Jobless- but not homeless- now retired 6 years It was on my XP system previously.Įmmons L-II, Fender Telecasters, B-Benders
Make sure you don't have a conflict with another audio device with Win 7.ĭownload and install the latest MAudio Delta driver for the 66. Why not ? I use the Delta 66 with WIN 7, it loaded just fine, the only thing that did not load was the stand alone Control Panel program which allows some features to be altered outside of the DAW. I appreciate you guys answering my questions. Vocals are the problem and as a singer I am bad enough without any issues. It would be great if there was something like that usb based.
It worked great with xp but I have never been able to use it a lot with windows 7 and above. It just had a break out box that accepted the signal from an external pre amp. The best system I have ever used is an M-Audio Delta 66.
