The matters described may differ according to the model. No User Data This product cannot save user data. Backing up user data during servicing is not required. Parts List A component whose part code is ******** cannot be supplied as a service part because one of the following reasons applies. • Because it is supplied as an assembled part (under a different part code). • Because a number of circuit boards are grouped together and supplied as a single circuit board (under a different part code). • Because supply is prohibited due to copyright restrictions. • Because reissuance is restricted. • Because the part is made to order (at current market price). Circuit Diagram In the circuit diagram, “NIU” is an abbreviation for “Not in Use,” and “UnPop” is an abbreviation for “Unpopulated.” They both mean non-mounted components. The circuit board and circuit board diagram show silk-screened indications, but no components are mounted. 2 DD-7 May. 2008 DD-7 Main Specifications DD-7: Digital Delay Nominal Input Level Dimensions -20 dBu 73 (W) x 129 (D) x 59 (H) mm 2-7/8 (W) x 5-1/8 (D) x 2-3/8 (H) inches Input Impedance 1 MΩ Weight 440 g / 1 lb (including battery) Nominal Output Level - 20 dBu Accessories Owner’s Manual English (#G2507366R0) Output Impedance Mode Sticker (#G2547154R0) 1 kΩ Leaflet (“USING THE UNIT SAFELY,” “IMPORTANT NOTES,” and “Information”) (#********) Recommended Load Impedance Dry battery/9 V type (6LR61) (#********) Application Sticker (#G2547160R0) * The battery that was supplied with the unit is for temporary use-intended primarily for testing the unit’s operation. 10 kΩ or greater We suggest replacing this with an alkaline dry cell.
