## Questions & Answers

**Q: Can I listen to two different audio sources at once? Say I wanted to listen to my monitor speakers and my headphones at the same time?**
A: I don't believe that's possible from this device. There are 2 in/out ports, but when I plug my headphones into one it cuts out the speaker so it appears that those ports can't be used at the same time. I think they have 2 in/out ports for the purpose of allowing you to have all plugs on one side of the device or your output on the opposite side from your inputs. The 4 ports that are activated by the buttons can only be selected one at a time.

**Q: If I use it as 4 in 1 out, can 2 inputs be active at the same time??? Thanks**
A: Hello. It can't. If you want simultaneous output, you can buy this one https://www.amazon.com/dp/B07R7NVN6L?ref=myi_title_dp

**Q: I need to be able to switch between 2 devices connected to my pc: my speakers and my headset with mic. will my headset microphone work if i use this?**
A: Yes . . . if you use a cable to connect the Nobsound front jack to your PC speaker output, then cable from your speakers into one of the Nobsound rear switched jacks then your headset mic goes directly into the PC and the headset speaker cable into one of other Nobsound switched channels. The switches are totally mechanical so there is 100% isolation between channels. It's a "selector", not a "splitter". It allows only a single-channel-out. Press one button, it stays down. Press another button, the first one pops up. It's not really 1-in-4-out, but "1-in-1-out at a time". The "Mute" is handy and does not cancel the selected channel.

**Q: I've had 2 and i love this. !s there a version that has volume control on the 2 output ports (leaving the priority feature intact) ?**
A: There is a new version with volume control. Best is to visit the their store here at Amazon to get accurate information.
