Ambient Eumel EMP 5 S Voltage Inconsistencies
I was testing the voltage on 4 Ambient Eumel EMP 5S 48V power converter and found the following:
EMP # 1 Voltage on Pins 1 & 2 = 6.15V and on Pins 1 & 3 = 2.18V
EMP # 2 Voltage on Pins 1 & 2 = 6.15V and on Pins 1 & 3 = 2.18V
EMP # 3 Voltage on Pins 1 & 2 = 6.15V and on Pins 1 & 3 = 0V
EMP # 4 Voltage on Pins 1 & 2 = 6.15V and on Pins 1 & 3 = 0V
All 4 Eumel EMP 5 S units will work with my Sanken COS 11-D, Sennheiser MKE2 which are wired for Lectrosonics servo bias.
My Countryman B6s (servo wiring ) will work on the EMP #1 and #2, but will not work with EMP #3 and #4 due to lack of audio signal/voltage on pin 3.
My Question. Has anyone had this problem or know of a change that Ambient made in the past? I am getting ready to take the units apart to compare
the different units, but I thought I would ask here first.
Many Thanks, mark
