The amps are manufactured in China, the speaker cabinets are built in the UK.

If this tiny package of electronics is able to run 8x 18nlw9601s, in other words, amplify bass for ~2000 people... then I am impressed. I know amplifier technology has certainly advanced over the last couple of decades, but, wow.

We have an interesting conundrum, where internals of the amp seem to disagree with use of the amp.
I just need to know details/specifications of output devices, and voltage/current ratings of PSU components. I don't subscribe to writing off amps, just because they are Chinese, because the Chinese will build to your spec, IF you monitor them, and enforce QA.

James is hardly far away or unfriendly, why don’t you just source a demo unit and try for yourself? |

Before I even do that, would want to know about components and their ratings. That would tell me about long term reliability, and likelihood of amp overheating, during normal operation, if not enough output devices, or insufficient current drawing/handling capacity of PSU. Demoing unit, would tell me how amp sounds, and how well it powers drivers.

The number of output transistors is not really relevant to switching amps like it is for AB. Also, to really know how a SMPS performs you need to test it or look at the schematic. A rough idea can be had from the size of the transformer, however you also need to know the switching freq.

Design, as much as the components used is fundamental to Reliable operation. Only a real world test would show suitability.

The 2 previous messages are very important.
One simple example. At same 100kHz switching frequency, a typical EE65 transformer used in many SMPS designs nowadays can deliver 1.5kw in Flyback mode but 3kW in resonant mode. That's not trivial... Then the DC-DC converter stage has also huge influence on the output capacity: switching at 70kHz with low efficiency MOSFETs / IGBTs and you get around 2kW in resonant mode but up to 5kW at 150kHz and X2 class MOSFETs. All of this to say that you can't judge these Saturn amps only by looking at them. The circuit design and the components used are in fact more important than only number of output transistors or how big are the PCB... |
