Use it as standalone mixer

Yes, get some TRS to XLR (Male) cables or adapters and plug them into either the monitor or alt outs, set your routing and levels and away you go.

Check the cables, then look at the mixer settings on the computer.

Unfortunately, the Behringer Xenyx x2442usb only comes with a stereo USB interface. The documentation is a bit misleading, but you can only record two channels through the USB interface - the main mix L and R. If you need to record more inputs than that, you'll have to do them separately.

The CD recorder need to have a Line input usually in the form of RCA Left and Right. Then you need to connect the appropriate cable from the Mixers outputs (line output not from an amplifier for speakers) to the input of the CD recorder. If you have no line outputs then a headphone output will do in a pinch but might be dirty sound. Make sure to keep levels low as in CD recording once you hit O there is no more level like on tape. It will just truncate the data and might give a clipped sound output.

You haven't told us where the "sound" is coming from... If you are ONLY plugged in one channel that is all that will be recorded. We can't guess at how you are setup. Please provide an adequate description. If you only have a mono signal to start with, then get a WYE connector and jumper to the second channel.

Look at the setups for voice and audio in the Windows control panel, "Sounds and Devices". Make sure the devices are set to the sources and destinations you want... This is not automatic and is a pain when you are going back and forth from recording and playing...

If you monitor the recording there are two delays... one as audio is converted and stored... the next is when it is retrieved and converted back to audio. Usually the recording interfaces have a monitor function that loops the audio back out before the conversion. playing back previously recorded audio of course will have the delay to retrieve and convert back to audio.

There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system. There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder. The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.

If you're asking about being able to use the DP-01s knobs and sliders to control the virtual knobs and sliders on some PC recording software the answer would be 'no'.

But if you just want to use the DP-01 to act as a mixer for incoming signals (like microphones and or guitars or other instruments) the answer is 'kind of'. The DP-01 cannot act as a usb interface for your PC, but it can sit in front of a usb interface or sound card and act as a mixer of sorts to mix input from instruments through the monitor outs and then into your computers sound cards or usb interfaces audio-in jacks. You are however limited to two simultaneous inputs though as that is all the DP-01 can handle.

Cheers.
