Apollo Light Drive

Light fantastic​


“The P1 power amplifier requires a super clean high current power supply to turn the low voltage line level music signal into hundreds of watts of output power. To do this, Siltech designed the Apollo Light Drive. A super-strong AC-powered light source is used to drive a photo-electric cell, giving a totally noise-free, galvanically isolated DC output. This then drives the amplifier’s output stage, keeping it absolutely immune from mains-born distortion. The idea behind this is not new, but its execution in a high powered amplifier is extremely challenging. The result is ultra-clean, low distortion power – and lots of it.”

Has anyone tried DIYing this concept?

I would also wonder about the physical size of the pv cell array.
To be large enough to supply the voltage and current required for any amplifier, I doubt it would fit within the footprint of any amplifier.
Me thinks there might be just a little 'marketing licence' going on.

What they forget is that any noise or hum on the light supply is transferred to the photo-electric cell.
So it boils down to designing a noise- and hum free lamp supply.
If you have that, you can skip the light stuff and use that super noise/hum free supply to directly drive the amp, saving you lots of money and headaches with no penalty.
But it's a great marketing concept and as such may well be worth the cost - to the manufacturer.
