Yes, I am aware of class D efficiency but not all class D amps run 'cool'. Some run warmer then others. My Wyred4Sound MMC 7 for example ran pretty warm but the larger MC runs cooler from what I have read. I have class D amps in some subs that run 'very warm' while some of my other class D amp subs run slightly warm. So that's why I ask where these amps are heat wise. Do you own a DSonic M3 series? I have heard the Pascal modules run relatively cool on the Funk subs so I wanted to see if these amps are the same.

Here is what I own:

3 D-sonic M3-600M-A's (LCR)
1 D-sonic M3-2000-5 (surrounds)
1 D-sonic M3-2800-7 (surrounds)

and again...barely warm to the touch.

^ That's great to hear, thank you! Can you also tell me how much space you have for ventilation? I would assume since they do not produce much heat that could probably get away with minimal air space above. Do you think an inch of clearance would be OK for these amps?

I haven't permanently mounted mine yet. Eventually, they will be rack mounted in a ventilated equipment closet (shown in my build thread). As long as you have adequate ventilation you should be OK but I would check in with Dennis to make sure.

D-Sonic ventilation

The smallest air gap provides adequate ventilation for the D-Sonic amps.

Sam,


There is no change in amplifier technology here.


The original power ratings are valid for 230VAC service. The new ratings reflect outputs at 115VAC service. Most of my customers have 115VAC so I decided to change the specifications for this reason. They actually put out approximately 10% more power than what I show but I opted for a more conservative rating.


Dennis
