Using The Programmer - Korg SDD-3000 Owner's Manual

E) Balancing Inputs or Outputs
It may sometimes be necessary to balance either the input or outputs of the SDD~000, in order to prevent ground loops
or to provide compatibility with pro studio or PA equipment. Since all outputs of the SDD-3000 can drive 600 ohms
directly, the use of one or more 'direct' boxes is the simplest solution.
Balancing the input requires a direct box with a balanced input and unbalanced output. The input impedance of the
direct box should be determined by the nature of the input source. The 10K minimum input impedance of the SDD-
3000 will accommodate almost any type of direct box.
Balancing the output(s) requires one or more direct boxes with unbalanced inputs and balanced outputs.
600 ohm - 600 ohm (1:1 ratio) direct boxes would generally be used, but higher impedances can be used if desired.
If transformer (rather than electronic) direct boxes are used, a balanced input or output may be unbalanced by simply
connecting the appropriate '-' line (normally pin 2) to ground (normally pin 1), and using the '+' line (normally pin 3) as
the 'HOT' connection.
F) Auxiliary Connections
Five auxiliary control inputs are provided: one Control Voltage (CV) input and four footswitch inputs.
The DELAY MOD CV input accepts an external voltage in the range of O to +5 volts.
Footswitches should be Korg PS-1 or S-2, or other momentary (normally open) type that switches to ground when
depressed.
Detailed descriptions of the DELAY MOD input and the PROG UP, PROG DOWN, HOLD and BYPASS
footswitches may be found in the Features & Functions section of the manual.

A) What is a Program
A program is a set of control settings that determine a given effect. The Delay time setting and all control and switch
settings within the Regeneration, Modulation and Effect Sections are programmable' - i.e., they are 'me morized' by the
programmer circuitry and may be recalled at will. The HOLD and Output INV buttons are not programmable.
