Can I simulate two mics at the same time?
Yes! This is what Dual Miking is about.
Provided you have updated the device's firmware, the VB-101 will simulate two speaker cabinets and two microphones at a time. Choose them from the library of available cabs and mics, and position them at will.
You can choose to place two different mics in front of the same speaker, or two mics in front of two different speakers.
If you need to update the firmware, connect the VB-101 to the free Torpedo Remote software while also connected to the Internet, and let the firmware update automatically. Then restart the device to complete the updating process.
