Dear
@restorer-john
Per our recent discussions, I have conducted comprehensive tests with two NCx500 modules incorporated into our Apollon NCx500 DM dual mono amplifier. In order to rigorously assess their performance, I subjected the NCx500 to demanding conditions: running them continuously for 5 minutes at 20kHz over 500 watts into a resistive 4Ohm load (0.001 THD+N), and at 1kHz over 500 watts into a 4Ohm resistive load (0.1 THD+N).
I'm pleased to report that the amplifier performed exceptionally, maintaining 500 watts at 20kHz for the entire 5-minute duration. Interestingly, the NCx500 modules exhibited lower temperature increases at 20kHz compared to 1kHz. After the test, the NCx500 modules reached temperatures of 60 degrees Celsius (140 degrees Fahrenheit), while the Hypex SMPS 1200 power supplies and the enclosure maintained a consistent 30 degrees Celsius (86 degrees Fahrenheit).
To further align with FTC standards, the amplifier was preconditioned at one-eighth of its rated total power output for one hour using a 1,000 Hz sinusoidal wave.
Through this examination, I hope to conclusively demonstrate the robust capabilities of class D amplifier modules, particularly in response to skepticism about their performance at higher frequencies and continuous power. The modules in the test were housed in a 2.5mm thick enclosure. Given this, it's exciting to contemplate their potential performance in our more robust 10mm enclosures or within our premium amplifiers, which feature expansive heat sinks.
Reflecting upon the capabilities showcased, I am compelled to ask: who might require power beyond what this offers? This isn't merely a powerful amplifier; it stands as a testament to unparalleled power, delivering remarkable performance, especially when considering its compact form, weight, affordable price and efficiency.
For optimal clarity, kindly ensure that the video quality on YouTube is set to 1080p or 720p.
In light of your valuable feedback, I concur that our website should provide more detailed specifications showcasing the true prowess of our amplifiers. Not doing so would indeed undersell their capabilities. Rest assured, we will be updating this information shortly.
Thank you for your insightful suggestions and unwavering support.
