So they claim this thing is capable of 1,280 watts of power??? I would reply and ask them if they could provide a measurement that demonstrated this.
Edit, adding some power loss, this will be at the limit of a 15amp outlet in US can provide.
I asked for measurements…here’s the reply:
John, we are arranging to measure performance of current production units of AD4 and to publish the results along with the analyzer scripts.
We’ll share those with you as soon as they are available.
This has their attention. Hopefully Starke will follow thru and publish here soon. My interactions with Starke on both the sales and service side have been very helpful and professional. Replies are prompt like the one I received from an after hours email today.
It’s too early to jump to conclusions or determine cause. This could be a quality, design, assembly, test, measurement, part, or some other typical manufacturing issue on one amp. It could also be a big issue, who knows. Let’s see what they find.
I have three AD4.320’s built in Jan 2021 and access to low FedEx corporate rates if you want to test more
