How to set up mixing board to record audio to my iMac. HALP

I'm trying to get some old interviews recorded on cassette tape digitized.

I'm using an Alesis Multimixer8 usb.

I'm just going on input into bank one of the mixer then out via USB 2.0 and then into the iMac via USB.

Any suggestions? I'm just using one input for all sound.

How would I do this?

This is real easy, but with enough variables as to get mind numbing. Ultimately, don’t sweat it.
Play the cassette, set the bottom pot to zero (you work out what is 0, can’t see detail) and set gain (first pot from the top) so it illuminates the green portion of the meters. Main mix should too be set to 0.
Connect usb into Mac, go to audio/midi and make sure audio is getting here so far. 24bit is your friend.
Open your recording app (voice memo in recent systems, QuickTime, etc).
That’s it, until the next issue rears its ugly head.
Good luck!

Do you need a mixing board? I use Audio Hijack from Rogue Amoeba Software to record from my receiver, via a Griffin iMic dongle that plugs into USB. Audio Hijack is excellent, inexpensive software.

I can record radio, phonograph, CD, or tape cassette via the receiver. Audio Hijack will of course record from any application or Internet stream as well.

I have an old iMic and use Audacity. Really easy. Still have about 100 tapes to digitize...

The best thing about using a mixing board with those old tapes is you can really do a lot to enhance and clean up the sound without going into post to do it with software ...

Here is where I am on the midi set up. Anyone know if this is right?

Slide up those input levels, of course. And check Sound prefs to make sure USB is the selected input device.

You won't get anything out of an Alesis mixer that you can't do in software. Alesis was notorious for designing decent stuff, then modified their designs to cut costs and severely lower quality. I would go straight into your computer line in, or a USB dongle.

1) If you are using a stereo output on the cassette and going in to a mono balanced input, you will get phase cancellation and a huge drop in signal. Youu would be better off going in to 2 channels, fed from L and R .
2) your input gain is cranked, possibly due to #1. Turn up the output of the cassette deck, if you can, and then turn down your input gain. Otherwise, you will be amplifying a low signal, along with a lot of noise.
3) It looks like you are drowning everything in reverb.
