Did you use the AyreLink cables supplied with the amps or two-line phone cables you had on hand?
I learned (the hard way) that some phone cables swap cable pairs between ends of the cable and some do not, and AyreLink
requires the ones that do.
If you hold both modular jacks of the cable facing the same direction, the center two pins and the outer two pins must switch colors in the cable run.
So, holding the modular clip on top and facing up as shown below, one
must be wired Yellow, Green, Red, Black as shown:
The other
must be wired (from left) Black, Red, Green, Yellow (where the yellow and black are swapped and the red and green are swapped from the other end.)
If you use cables that do not, (some are wired such that both ends are the same color sequence), bad things happen in the
precise way you describe (as far as I can tell from both connected devices trying to "transmit" to each other and/or simultaneously providing trigger output voltages on the same pin); the amp's control circuitry can be damaged as a result. The way you can tell this damage has occurred is if when pressing the LED, the color changes from green to blue with no accompanying "click" from the internal relays; if your amp is exhibiting that behavior it will need to be repaired.
I wish Ayre would put a
big flashing warning in their manual about this, but as they pack an AyreLink cable with each amp (or at least with each MX-R Twenty), I suspect they feel they've got it covered.
