Technics SU-R1000 a new Class-D GaN Technology integrated
I think we already found that the SU-G30 it was not 1.5mhZ switching speed just after it was released, but around the 600khz that most uses today. Can you put up a link to show the 1.5mhZ switching speed PS: Sorry, you maybe right, that could have been the SU-G700 that wasn’t 1.5mhZ, maybe the SU-G30 is? And if so then the SU-R1000 would have to follow also, they’d be mad not to. Cheers George |
There is a graph at http://https//www.technics.com/us/products/grand-class-g30/network-audio-amplifier-su-g30.html near the top in the JENO Engine section The graph is labeled "Output of G30 JENO Engine". And in the graph it says 1.5 MHZ operation. I am not totally sure that is the switching speed though. Technics just mentions "high speed switching" in other places without explicitly stating the actual number when talking about the SU-G30's GaN-fets. |
Yes that it, when I queried Technics on it with the SE-R1, and one of the reviews also backed it up. Wow that means the SU-R1000 should hopefully have the 1.5mhZ switching speed also, when it comes out in mid/Feb 2021 They must have listened to what Cyrill Hammer designer of Soulution Audio had to say about Class-D "if you want to have your product performing at the cutting edge it is not possible with today’s known switching technologies. In order to come close to the performance of the best linear design we would need high-current semiconductors that provide switching frequencies of several MHz or even GHz."https://soulution-audio.com/series7/soulution-701-mono-amplifier/ Cheers George |
