The specs for the Terk VR1 power adapter are 12V DC, 200 mA and the center pin is positive.
If you are recording via USB on the TUNVR1, we recommend a couple of things relating to the drive performance:
- We strongly recommend consumers use USB 3.0 drives with high speed writing capability. This will help prevent micro blocking in recording and playback. Many USB drives 2.0 and earlier have very slow write speeds and the memory in the tuner won’t prevent playback recording issues.
- We recommend drives up to 2 TB for connectivity to the TUNVR1.
