Default Test Bench

Here is my test bench. This is what I will be using on all future amps I test.


Sony CDX-GS500R

Left switch turns on the deck.
Left Volt meter measure the battery the deck is hooked up to.

Right switch turns on the remote signal to amp.
Right meter is hooked up to amps power source: ultracaps





Powered by spare battery.











Power supply used to charge up the ultracaps. I cut it off when testing amp.

Can adjust voltage from 3v all the way up to 17.18

Also has a current limiter which is very useful with caps since they can suck you dry.

Rated at 26amp @15v





Maxwell Ultracapacitor
Have another two banks at my disposal.

Looking for more.





Resistors.
Each rated at 1k watts rms
I'll be mainly wireing a pair to 2.5ohm and all to 1ohm but they can also be wired to 1.66 and 1.25









Putting a fan on one end was very effective in cooling them down between test.







DSO Nano to test signal quality





This is what you'll see on most test.
The fluke clamp will be measuring dc current that the amp is drawing from the ultracaps.

The cen-tech will be measuring voltage at power source:ultracaps

The dso nano will be measuring the ac signal the amplifier is putting out.

And the extech will be measuring true rms ac voltage that the amp is putting out.

voltage/resistance= current
Voltage x current = power





Testing the rca out put signal.

60hz 0db tone at max volume. 0db subwoofer level on deck.





60hz 0db tone at max volume. +1db subwoofer level on deck.





Test in progress.

Very similar setup to mine. That's awesome. I need to put in some work on the actual "bench" part of my bench though. My shit is strewn all over the place.

Nice work.

Caps don't have much reserve, they excel at providing instantaneous current preventing voltage drop. With 3 banks they can support about a 3 second 500A load with less than a 1v drop. The beauty of it really shines when doing consecutive tests and need consistency in supplied power, caps are able to charge to the same point every time.

Awesome test bench OP! Makes me want to build something with all the extra stuff I got laying around.

Seems like more and more of us are doing test benches. I've had mine for years.

Those look just like the Ebay/China special ones I got, except my display is green. How much smaller are yours?
