x1Aremote

Measure independently from x1Analyzer location.

With x1Aremote you perform measurements independently of the position of the x1Analyzer measurement setup. This makes it easy to perform acoustic measurements from the listening position or outside the measurement room, for example.

Highlights

1. x1Aremote software is free of charge
2. Connection to x1A PC via local network
3. Choose measurement type
4. Set start/stop measurement frequency
5. Set frequency range via preset buttons
6. Select measurement channel
7. Display up to 6 channels parallel
8. Save measurement on the x1Analyzer PC
9. Zoom in/out in the measurement diagram
10. Share/copy measurement diagram

Multi-Plattform

You can use x1Aremote free of charge with your PC, laptop, tablet PC, or cell phone:

1. MS-Windows 1)
2. macOS 1)
3. Android 2)
4. iOS 2)

1) Download from our homepage
2) Download from App Store (Google / Apple)
Important: x1Analyzer Ver 2.8 is required to use x1Aremote.
