Record in and out jacks?

Tape Loop?

Read about it, all kinds of things.

You can add different things between the loop, like a DSP unit, and EQ, Tape deck, RtR all kinds of goodies.. Then disengage the loop to remove them from the sound path.

It’s a monitor for recording mainly.. or Adds tape EQs depending on the bias settings and tape used.. It is a good option to have in any case.. I sure like Macs old set ups..

"Record out / line out" can be used as another "pre out". I used mine for my headphone amp because the pre out was feeding a MiniDsp bass array.

I use them to record content via a digital interface, e.g. if I have an old vinyl album I want to play via one of my streaming units.

So I am glad to see they are still provided, at least on my amp :-)

The digitizer is a Behringer UP-222 unit that costs around $30 and delivers up to 16/44 digital tracks and comes with the software to accomplish this. All that's needed is a USB cable and a computer
