ARC Ref 6 - Is it normal?

Check and make sure your ac cord is fully plugged into the back of the ref 6.
I also had this problem once fixed it by fully inserting the 20 amp pc cord.

There is another problem I have found,  my Ref 6 cannot turn-on from time tom time.  I already check very careful my power cable is fully plugged into my Ref 6 and my Audience aR6-TSS power conditioner very tight. What I need to do is to switch-off my  Audience power conditioner, wait for about 10 seconds then switch it on. After this, I can turn-on my Ref 6. Recently I found this problem comes out very often.   But last month when the temperature was not very cold, I don't  have this problem (I just bought my Ref 6 in Jan).  I only have this problem  recently when the temperature getting  cold.  I guess maybe my apartment use a lot of current because many neighborhood use heater in evening.  At a result, voltage is drop.  Do you think this is the problem?  How can I solve this problem?  (but in my area - Hong Kong,  cold season is very short, maybe only 1 to 2 months a year).

Another thing I forgot to mention, I'm using a Shunyata 15A to 20A IEC converter for my Furutech DPS-4 power cable on Ref 6.  Do you think this is also a problem because of bad connection on Ref 6?

PS:  I just bought a 20A version brand new Shunyata  Sigma Analog PC for my Ref 6 today, I haven't use it yet and I hope it may solve this problem.

Your power conditioner may regulate the voltage, which would prevent the voltage dip that the REF 6 is detecting.

One of the main advantages of having a power conditioner in the first place is getting a regulated constant voltage as your AC power fluctuates. Secondly and perhaps more importantly, a gear such as a ARC Ref 6 deserves a dedicated circuit. Sharingthe same circuit with an electric heater which probably has thermostatically controlled on/off switch with a piece of gear like that Ref6 is borderline criminal.🙄

I believe that none of the Audience conditioners provide voltage regulation. (I use their aR2p conditioner, by the way). However they are said to provide "partial power factor correction," which I suspect refers to some kind of passive (rather than active) power factor correction (PFC). During the 10 second period you referred to presumably the capacitors in that circuit are discharging, and (just my guess) the root cause of the problem might be some kind of interaction between the Ref 6 and the PFC circuit. With the presumably lower line voltage during the present cold weather period that you mentioned perhaps also being a contributing factor.

I would suggest that you do two things:

1)Try plugging the Ref 6 directly into the wall outlet, and see if the problem still occurs.

2)Get a multimeter and measure your line voltage, both when the problem occurs and when it does not occur.

Good luck. Regards,
