Power requirements for GCP (phantom power)
Posted: Fri Jan 13, 2017 8:38 pm
Hi,
Using GCP with a Hughes & Kettner Grandmeister using its phantom power and 7 pin cable. The GCP works for a few minutes and then the lights get dim, thing starts schizzing out, and then I start getting crazy control messages being sent.
Unfortunately the solution seems to be plug in the GCP to a wall wart. On it's own power it works fine with no glitches.
H&K Manual lists phantom as 20VDC at 150mA on its midi in port. Just curious what the spec requirement is to power this GCP on phantom.
Anyone know someone that makes a box that you can plug a wall wart into back at the rack and have it apply power to the correct midi pins?
Curious if you have seen this before with the HK amps.
Thank you
