## Questions & Answers

**Q: Can these be connected to skytronic 125.061 100w 4ohm ceiling speakers?**
A: not sure.i have them connected to jbl 100 w speakers. copes fine

**Q: Can I use it for 2 Technics speakers, 3way, 6ohm, 100w each?**
A: I've got it wired to my old Gale Gold Mark 2, rated 6-8 ohms 100w I think? Sounds great!

**Q: I want to use a 12v adapter. What size adapter pin/head is required? I have tried a few spares that I had, but none of them fit.**
A: OD: 5.5mm; ID: 2.5mm
BT20A comes with a 24V adapter, you can find one like its size.

**Q: Can a technics direct drive turntable work via the rca input or does the turntable need a preamp?**
A: The input sensitivity is stated as less than or equal to 280mV. If your turntable outputs I similar voltage (I guess in the range of 150 to 280mV) then I would say you probably don't need a preamp. However, if it's output is a lot less, you will need a preamp. Fosi have a range of turntable preamps to choose from. Look up the specs of your turntable to find it's output voltage range. Hope that helps.
