Answer B) Both outputs (headphones and line out) are active at the same time. The volume of both outputs is changed by the one rotary knob.

Hello left turn_ According to the data sheet, an impedance of up to 430 ohms is specified for the monitor output. However, I have not tested this myself. https://focusrite.com/de/audio-interface/scarlett/scarlett-solo I hope this helps you.

Do you mean headsets or headphones? The device has only one XLR input and only one microphone preamplifier, so only a condenser microphone (e.g. Beyerdynamic headset) will work.

A 6.5 mm adapter is cheaper and works

In my opinion, yes. However, you can only connect 1 input device, microphone or piano. There is the bigger brother where you can connect 2 devices.

Yes, active speakers such as the PreSonus could be connected. The unit has two line out connections at the back. https://www.digitec.ch/search?q=presonus

Hello In itself it should work. But remember that the connection is only a monitor connection. That means you only hear what goes into the interface as input. You will not hear sounds from the computer.

Hoi - On the Focusrite site you have a large selection of tools that come with the product: https://focusrite.com/de/usb-audio-interface/scarlett/scarlett-solo See towards the middle of the bottom of the page... lots of tools... LG

Yes, with an adapter 6.3mm jack plug to 3.5mm jack socket, e.g. InLine Audio Adapter (jack adapter)

Theoretically yes, but I have not tested it. However, I would advise against it. There are a huge number of different hubs and problems could occur. (inaccurate power supply, software problems, USB bus conflicts.) In Bern, there is an audio shop near Weisenhausplatz that lets you test equipment there. Maybe there is something like that in your area, then you can try it out.

Unfortunately, I can't answer that. I bought the device and returned it immediately because it did not meet my expectations.

Voices are NEVER recorded in stereo. However, I can still highly recommend Focusrite, the recording and playback quality are very good.

I did not use the unit but sold it on as it cannot be used standalone but only via a computer. I don't know anything about plugins, sorry.

The only cable you need from the PC to the Focusrite is a standard USB cable, which is included. The connector on the back of the Focusrite is USB-C and the cable has a USB-A connector on the other side. The device works fine with the standard drivers from the operating system, at least under macOS.

Yes, but note that there is a limit in the number of tracks that can be recorded simultaneously. I think the limit is one line level (pre-amped) and one at INST level (e.g. mic or guitar). If you wanted to record more than that you'd need the 2i2 or 4i4 etc. I would suggest buying the 4i4 or higher anyway because that will future proof you in case you want to record yourself, e.g. in a band and be able to manipulate the tracks individually in a DAW.

no, is not included

I haven't tried it myself, but I assume that an electric guitar should work there without any problems. There is also a button to switch the jack between instrument and microphone mode.

Not cables are not included.

The thing already has 48V phantom built in. It uses USB as a PC connection and is recognised as an audio input, thus recognisable for any software.

Stereo

Exactly, with direct monitoring off, the ring signal is not monitored, only the output signal.
