speaker level sub hookup on class D?

I have a W4S ICE amp and was wondering if it would be OK to use the hi level speaker inputs on my Velodyne DD-15 sub? Reason being that the amp is fully balanced differential something and my sub seems to sum both channels to a mono signal. Since my amp does not use a common ground is it OK to do this? I have already asked W4S and they were not sure. Velodyne tech help is away until after the New Year. I would like to run wires from my amp output to the subs hi level input. Thanks for all replies.

Magfan, both 500ASP and 1000ASP have two voltages 50V/80V and 80V/120V respectively, where first (lower) voltage they call "preload". I'm not sure what it means but from my calculations they use higher of two voltages for output stage.

Kij,
Yes, and I'd expect the 250ASP to also have 2 voltages. Since I own the ASP500 I haven't bothered to look at the other 2 modules.

Don't forget...and I don't know how this plays into it, that these modules are designed to power other B&O modules....from another series which are not self powered. So, for the ASP500 powering a lower power module, it may make sense to tap the 50v rail and if powering a 500 watt module, use the 80v rail.

If I were doing 'professional' sound reinforcement gear, this would be an option to look at.

Magfan, you're right - I forgot about it.
