Touché!Or switch to 1/4 inch TRS and listen to people scream about all the XLR cables they already own, as they did on the Topping DAC threads.
Real men don't whine about cable connectors.
(Only joking, so please don't anyone take that comment as an attack.)

Are you sure it isn’t an N connector you saw on the scopes? They are similar to BNC connectors except larger.
I have never seen an N connector on a scope. Why would you use a connector whose purpose is to carry more current and/or weatherproof, on a scope?
I think you might be confusing BNC and N connectors. Both were common on oscilloscopes and look similar to each other.

Not only did I get an answer, someone who had their coffee and was wide awake schooled me on the right question to ask. ASR is an audio persons dream!

I've only seen n-connectors used in gigahertz applications. We used them for driving signals to dut rigs for asic characterzations.
Adam, I am properly punished. My wife read this and quickly throat punched me and walked away saying "Don't do that again". When I could breath again, I tended to agree with her. I don't want another throat punch again!
Yes. Looking at the documentation, Hypex provides a connection point that isn't connected to anything (that's what Rick means by "open collector output" unless there is a clipping situation, at which point that connection is switched to ground. When it is switched to ground, it will pull voltage through an LED and resistor combination.It is pretty simple. Going to be doing for Adam's amp after Amir is done.
The signal is open collector and so just needs a Vaux positive power connection to an LED with a drop resistor.
The trickiest aspect is the adding a pin to the IDC connector to tap the signal.
So, Vaux output (J6.1) gets wired to the anode (longer leg) of an LED, then from the shorter leg to a 2K-Ohm resister, and then to J4.5 (for Ch 1) or J4.12 (for Ch 2). Vaux is at 19 volts max, and a 2K resistor will pull 10 mA through the LED. I think most standard LED's would be fine with that, but a higher resistor will pull less current, so that can be tailored. I see a zillion T-1 (3mm round hole) LED's at Mouser for under a buck. I probably already have some in my parts bin.
I'm thinking a single wire from Vaux to Ch1 LED anode, and from there to Ch2 LED anode, and then wire the tails through resistors to the clip signal pins via separate wires.

Hi, maybe that's what some are looking for. But the Company is UK based.

Wonderful amp, wonderful review. I am the lucky owner of a Buckeye NC252MP x 2 well over one year old, used daily with a Benchmark DAC3 DX driving it over a set of ProAc Tablette 25th anniversary (+ REL SW). Flawless performance so far, excellent enjoyment of Music. Highly recommended brand. Once you get used to it, the release button of the XLR at 180 deg has the advantage to be easier to push when bulkier speaker cables are mounted in place.
No, because the 502 allows 2-ohm loads.

Isn't it this plot in the OP? Not sure the measurement bandwidth used...
