Switch Position Delay Time
Min Max
Short 136ms 440ms
Long 480ms 790ms
This controls the balance of the direct sound [input signal] respective to the effect (wet)
sound [the signal processed with the delay effect] that will be output. Rotating it
counter-clockwise increases the volume of the direct sound, while clockwise rotation
increases the volume of the effect (wet) sound. If you rotate the control fully counter-
clockwise or clockwise, respectively dry or dry+wet sound will be output.
*To connect the DD1000 to the Send/Return jacks on a mixing unit, be sure to
rotate the MIX control on the DD1000 fully clockwise i.e. to "wet" Position,
To get the applied Return Input at Effect Output Jack.
5. Output Level Control :
This knob is used for adjusting the output level of the unit turning it clockwise to get
the output level.
6. Power On Led :
This indicates the power on status of the unit.
7. Mic Line Switch :
This switch is used to select either MIC-2 or Line Input.
8. Short/Long Delay Switch :
This switch is used to select Short or Long delay
9. Delaytime Control :
This control adjusts the delay time [the time it will take for an echo to return]. Turning
the knob clockwise, make the delay time longer.
1. Mic-1 Level Control :
Controls the volume obtained with microphones connected to MIC Jack on rear
When not using the MIC jacks, turn the level control all the way down.
If howling occurs, rotate the level control counter-clockwise to lower the
volume.
2. Mic-2/Line Level Control :
Controls the volume obtained with microphones connected to MIC-2/Line Jack on
rear
When not using the MIC jacks, turn the level control all the way down.
If howling occurs, rotate the level control counter-clockwise to lower the
volume.
3. Send Level Control :
Controls the level going to SEND output.
4. Mix (Balance) Control :
10. Feedback Control :
This control adjusts the feedback amount [the number of repetitions] for the delay
sound [echo]. Turning the knob clockwise increases the number of repeatation.
As you turn up the FEEDBACK knob clockwise oscillation may occur. If this
happens turn the knob down until the oscillation stops.
