You say the Anthem has a pulsed on-off signal. You say "a," so it's one signal. You say on-off, so it's a toggle. One pulse to turn on, same pulse over same wire to turn off.
And yes, the Xantech would have to receive 12 volts as a turn-on signal, then have no voltage, then twelve volts as a turn-off signal, perhaps running the signal throught a CC12 relay.
Look at page 4 of the manual (figure 6)for the Xantech. It does exactly what you need to control Proceed or a Mark Levinson Amp with a more traditional 12v on for amps on and 0v for amps off.

I am done with this as well as you do not understand the concept or definition of "pulse", "discriminator", "series", "flip/flops",or anything having to do with data streams and how they are generated or decoded or the final output configuration of the microprocessor to energize any given circuit or device. I do indeed understand some, not all, of these things. I have disagreed with you several times when you consider a series of pulses to be a pulse. You have not responded to that, but gone on to something else. You really should look past the most basic operation of the remotes you use to learn HOW they function before arguing with someone who designs control circuitry. I tried to forestall this long series of quibbles. I said that you and I must be talking about different things and I asked you to explain the differences, but you just repeated yourself.

And to sum it all up: I would never trade reliability for efficiency OR for a wiz-bang gimmick! Efficiency is no good to me if unreliable and wiz-bang gimmicks only end up being trouble in the end.

I had this exact same frustration/question when I got my Proceed amplifiers. I had them connected to my Anthem AVM20 and sure enough, the Proceed amplifiers wanted a pulse on and off and the Anthem like all newer processors only did a constant 12v current. The Xantech 599 does the trick. I documented the steps and how to connect here: http://pooraudiophile.blogspot.comIt works flawlessly and highly recommend the Xantech!

I have solved this using a Raspberry Pi 4 b and a 12 V relay: [Link: github.com]Its my first Raspberry project so others may know a more graceful way to do this: # Plulse conversion from constant 12V input #This assumes your Mark Levinson APM is on Standby as start state #Your input to the Mark Levinson Should connect to GPIO21 for + and a GRND #The control Signal from constant high or low should connect to a 12 V relay #the switch signals from the relay to toggle on/off should be connected to GPIO twenty six and GRND import signal import sys from time import sleep import RPi.GPIO as GPIO from gpiozero import LED, Button from gpiozero.tools import booleanized, all_values GPIO.setmode(GPIO.BCM) AMP=21 #Control Signal to amp GPIO.setup(AMP, GPIO.OUT) Button.was_held = False def held(btn): #when siglnal is high and stays high btn.was_held = True print("button was held ") GPIO.output(AMP, 1) sleep(.3) GPIO.output(AMP, 0) def released(btn): #when signal is low and stays low if not btn.was_held: print("Release1") pressed() else: print("Release2") GPIO.output(AMP, 1) sleep(.3) GPIO.output(AMP, 0) btn.was_held = False def pressed(): print("button was pressed not held") btn = Button(26,bounce_time = .001) # relay is on pin GPIO2 and GRND if __name__ == '__main__': while True: btn.when_held = held btn.when_released = released sleep(1) GPIO.cleanup()

It only took 12 years for the solution.

This "solution" is no solution. It uses a more complicated product. It needs programming, which none of the other solutions require. This programming must be learned or at least followed step by step. I believe it occupies more real estate when seen two-dimensionally and more volume when seen three-dimensionally.
It is SEEN as the solution because we're used to picking an actual computer off of a shelf and programming it to do a tiny thing.

PI is a tiny computer. It’s a tool. We each have a collection of tools that we regularly use. Someone who has access to a machine shop will use a lot less duct tape than someone who uses simple hand tools. Electricians have a bag of wire nuts, I have a soldering iron and crimps. We might have one dull saw. A cabinet maker will have a collection of sharp saws. He can fit a countertop in minutes, we’ll probably struggle for hours.
In one case I threw together a single board computer controller for a project that could probably have been done with time delay relays, latching relays, NE555’s, flip flops, and a little logic. Since I had the computer, EPROM burner, and a programming system on hand, similar to the machine shop guy, I had the controller ready for deployment in a few hours. This was much less elapsed time than would have been required to design, scrounge parts that were not on hand, build, and test a Rube Goldberg sort of controller. And, I needed the controller the next day. Multiple inputs and outputs, timers, logic, and management for power up and power failure were easy in the program. This was way before the PI existed.

No excuses, buzz. No excuses.

And, a 3D printer person would approach a problem very differently from a traditional machine shop guy or our duct tape guy. It's a new world. Sure, lots of clever things can be done with an R/C network and some relay logic, but a very cheap computer board could watch the CEC bus, accept WiFi commands, and perform much more complex logic. It's just a different set of tools and a different set of skills. The 3D printer person would probably feel helpless in a machine shop and the reverse is true too.
