INTRODUCTION THE PDS-3500, THE MIDI PEDAL
The PDS-3500, THE MIDI PEDAL, is a foot controller that will let you enter a series of MIDI pro-
gram changes and recall them at the tap of your foot. Although the PDS-3500 is in a foot switch format,
the touch pads can be actuated with the gentle touch of your finger so that you could use the unit on
top of your keyboard. With the addition of the FX-17, Wah/Volume controller pedal, the PDS-3500 can
be used to control MIDI specification continuous controllers like volume and modulation depth, as well
as pitch bend and channel pressure.
The PDS-3500 is housed in a DigiTech dual foot switch cast-metal housing. The left foot switch pad
is the BANK/STORE switch. It is used to advance the BANK number and to store data when program-
ming. The right foot switch is the PRESET/INCREMENT switch and it is used to advance the PRESET
number and increment the data values during programming. The top of the housing has two three-
position slide switches. The left-hand slide switch is the MODE SWITCH. It selects the OPERATE mode,
the PROGRAM mode, or selects the PEDAL STATUS number during programming. The right-hand slide
switch is the DATA SWITCH. It selects during OPERATE(ing), one of two operating modes: BANK/
PRESET or BANK DUMP or during PROGRAM(ming) selects: BANK and PRESET, PROGRAM CHANGE
number or MIDI CHANNEL number.
The PDS-3500 also has a four-number LED display mounted on the top of the chassis.
On the right side of the PDS-3500 chassis are two jacks: the D to +5 volt input from the FX-17 pedal
and the A.C. power adapter jack.
The PDS-3500 requires the use of an A.C. power adapter IDDD PS-3 A.C. power adapter to operate.
NOTE: The use of any other A.C. adapter other than a DigiTech or DOD power adapter will void the war-
ranty.
The 9-volt battery found under the plastic cover on the top of the unit is to back up the settings pro-
grammed into the PDS-3500 when the A.C. power adapter is withdrawn from the unit.
On the left side of the PDS-3500 is the MIDI output jack.
