Questions & Answers

  • Q: Is a30 220v version?
  • A: Hi Nathan, it can be used for 220v. Thank you!
  • Nathan 5/11/19 10:48 PM Asked.
  • Q: Hello Is it possible to connect all three of the Topping components ie. D30 rca to A30, then rca from A30 to the VX3?
  • A: Hi Luke,yes,it can.Thank you.
  • Luke 9/15/17 11:45 AM Asked.
  • Q: Thanks a lot for your quick answer. Still don't understand, it says in the description: "0dB/9dB/18dB gain switch. High/Low impedance switch." What does H/L switch do?
  • A: hi Fabio,High impedance headphones choose H, low impedance headphones choose L.Thank you.
  • Fabio 3/6/17 3:12 AM Asked.
  • Q: Hi, What are the output impedances of High/Low switch?
  • A: Hi Fabio,Output impedance has nothing to do H/L switch , only linked to the headphone jack.The 3.5mm is 30Ω.The 6.35mm is 10Ω.Thank you.
  • Fabio 3/5/17 9:55 AM Asked.
  • Q: Hi. I'd like to know if the line output is fixed or variable.
  • A: Hi Marcel,the line output is fixed.Thank you.
