New KEF KC62 Not Responding?
Hi all. I just tried adding a KC62 to my Ragnarok 2 / LS50 Meta system. Per KEF documentation, I connected the Ragnarok preamp out to LFE (L) and Smart Connect (R) inputs on the KC62 and set the subwoofer in Manual mode.
Fire up "Dark Side of the Moon" on the turntable and... nothing. The KC62 just sits there with orange (standby?) light on and does not turn green.
I expect that I'm missing something really obvious and appreciate any help here. I've emailed KEF and Schiit but have not heard back yet. Thanks in advance.
I don't believe you should have anything plugged into LFE on the sub and it should be set for manual. You need a Y cable to combine the L/R from your amp into a single mono into the sub. I have two of these subs at home, one in an upstairs TV room with a pair of Kef LS50 wII and another in a system downstairs where it is fed via a single rca cable. I will check tonight and post if you havent got it sorted by then.
I posted a photo of the back of my KC62 on my system page. A link is below. I apologize for the dust and the hair from our English Cream Golden Retriever. LOL. This is on and operational when I snapped the photo. Best wishes
Which output mode are you using on the Ragnarok 2? The pre-outs are active in headphone+speaker and headphone-only modes. Pre-outs are not active in speaker-only mode (in other words, you need to select a mode that includes headphones). It is in the owners manual. I and many others think this is very strange.
See Jason Stoddard’s comments:
@dprendergast Pleased to hear you got it going. The connections on your amp are very unusual and far from intuitive.
As you may have read, I am shortlisting two or three KC62s in my system. Opinions seem to be divided. Some say the new tech is a breakthrough that enables small subs to perform like larger ones. Others say a small sub can never produce strong deep bass. Most reviews are very positive, at the 9/10 level.
It will be really helpful if you will report your findings after you have run them in and listened for a while.
OK, I've had a full week with the KEF KC62 subwoofer now. The rest of my system is a Rangarok-2 amplifier, Rega Planar 1 Plus turntable, and KEF LS50 Meta speakers.
My taste in music is somewhat eclectic: I listen to a lot of jazz and big band now, along with an enduring enjoyment of mainstream pop/rock (Elvis Costello, Beatles, etc.) and of classical music up through the Romantic period.
Before describing my experience and impressions so far, I want to make it clear that I am not an audiophile and do not consider myself to have a very discriminating ear. This might understandably make what I have to say of little interest to many of you.
In sum, I am extremely pleased with what I have now. I might upgrade the cartridge on my turntable at some point. Aside from that, my only additional investments might be in modifications to the room I have the equipment in.
Here are the records that I listened to during this week of burn-in and testing:
