Ground Control: ....If you are not using the GCX, but have a device that supports
phantom power via a 7-pin MIDI cable, this device can power
the Ground Control. Connect the 7-pin MIDI cable from your
Ground Control's MIDI Out to the 7-pin MIDI In on the
device.......
Herbert: ....Midi in receives “program change” orders from commonly available midi pedals
and control systems. The Herbert is able to supply phantom power to your midi
pedal via a 7-prong DIN midi cable. This can help unclutter your stage system
and rids the artist of these pesky power supplies.
Pin 1 and 6 is ground (-)
Pin 3 and 7 is hot (+)
The voltage is 9-12V AC or DC, which is acceptable for 98% of all midi pedals.
Maximum power usage of the pedal cannot exceed 800mA (0.8A)
Please observe proper polarity to avoid damage to the MIDI pedal.....
I have a Rocktron 7-pin midi cable. It's 30 ft. long and a good quality cable - but I don't know, if this is available in Shanghai......
