Title: Are my REF9V3se amps Direct Coupled or AC Coupled ( if AC, what size caps ? )
Post by: Ike Carumba on 26 Mar 2015, 11:30 pm

I would like to know if my NuForce REF9V3se amps are direct coupled or AC coupled. If they are AC coupled what are the values of the coupling capacitors ?

My DEQX processors are being upgraded right now and the ( authorized DEQX ) tech asked me to find out.

Before he's done the tech will track down and replace the faulty component but he wants to know if the NuForce amps are input capacitor-protected in case the fault should recur.

Thank you.

There is a capacitor on Ref9V3SE, so its AC coupled.
The value of the capacitor 1µF 250V (WIMA FKP4).
