MIDI THRU
Standard MIDI thru, passes data from the MIDI IN to additional MIDI gear.
MIDI IN
Standard MIDI input. Use this to connect any standard MIDI controller.
Special Combo MIDI In And DC Power Out
This connector is labeled "RIVERA MIDI PEDAL ONLY"
On earlier versions of the Knucklehead, this connector is labeled "FTSWITCH FS-9
ONLY". (The original name for the Head Master was the FS-9). The function is exactly
the same, only the label is different.
In addition to being a standard MIDI IN, this connector ALSO provides DC power to the
Head Master.
Even though the MIDI connector has 5 pins, only 3 of them are used. The other two are
undefined by the MIDI specification and unused by most MIDI gear. The Knucklehead,
and all future Rivera MIDI enabled amps, provides DC power on these pins.
Warning: This connector should ONLY be used to connect the Head
Master or other Rivera MIDI pedal. There is no agreement among
manufacturers on the use of these two pins. Some manufacturers also
use them to provide power, but it may be a different voltage or polarity.
If you plug a cable from the special Combo connector into another
device, and that device ALSO uses these pins , BOTH devices may be damaged!
