Korg SDD-3000 Owner's Manual page 5

a) Audio Input Jacks
Separate input jacks are provided on the front and rear panels, for maximum convenience. If both Inputs are used the
front input has priority and the rear input is internally disconnected. The two inputs are otherwise the same.
Input level from either jack is affected by the input ATTENUATOR switch and LEVEL control.
b) ATTENUATOR Switch
This switch selects the basic gain an input impedance of the input stage.
It should be set to a position matching the output level of the equipment feeding the SDD-3000, in order to achieve the
best dynamic range. Equipment ranging from electric guitars to professional studio mixers can be used with excellent
results.
C) Input LEVEL Control
The input LEVEL control should be used to match the SDD-3000 to the actual output level of the connected equipment,
once the proper range has been selected with the ATTENUATOR switch. It is very important to Set the Input level
carefully, so as to reduce noise to the lowest possible level while avoiding distortion. The HEADROOM LED m eter
should be used to establish the proper setting.
d) HEADROOM LED Meter
The HEADROOM LED meter 5 calib rated in 5dB steps from -20dB to 0dB (Green LEDs), with a separate Red LED
indicating +3 dB. It is used to establish proper levels and maintain good head room throughout the SDD-3000.
2. Programmer Section
Nine separate effects 'programs , or collections of control settings, may be stored, recalled and changed at will. The
stored or 'programmed' settings include the delay time setting and all control settings within the Regeneration and
Modulation sections.
The Programmer Section Contains the following:
a) Program & Delay Time Display
b) PROGRAM Button
c) WRITE Button
d) UP & DOWN Buttons
e) PROGRAM UP & DOWN Footswitch jacks. (Rear Panel - ?)
a) Program & Delay Time Display
The left-hand digit of the 5 digit LED display indicates the currently selected Program. Nine different programs may be
stored and recalled in addition to the Manual setting. A "0" in the display indicates that the Manual (front panel) made
Is selected, while '1' - '9' indicates that one of the nine stored programs is selected.
A decimal point appears in the lower right corner of the Program Display when the currently selected program has been
temporarily edited.
The four right-hand digits indicate the current basic Delay time setting. Delay time can range from O millisecond
(0.000 second) to 1023 milliseconds (1.023 seconds), in 1 millisecond steps (.001 seconds).
