To prevent that, replace the battery a little earlier. AC ADAPTOR (OPTION) • Be sure to keep the battery snapped by connector into the housing, when using AC adaptor, too. *Even if AC Adaptor cord comes out during performance, operations immediately changes to battery, causing no trouble in continuing performance. • Power is switched on while a plug is put into input jack. When you do not use, keep the plug off the jack. > For AC operation, be sure to use the BOSS AC Adaptor PSA-120, 220 or 240 depending on the voltage system in your country, and never use one Adaptor for two units simultaneously. CAUTIONS FOR REPLACING AND HANDLING BATTERY 9V BATTERY PEDAL(COVER) THUMB SCREW SPRING BASE COIL SPRING PEDAL GUIDE BATTERY CONNECTOR sBATTERY STRAP REPLACING BATTERY USE ONE 9-VOLT BATTERY. O Loosen the screw of pedal to open it and take out battery from its housing. ©Replace the battery by a new one and put it into position. ©Set coil spring onto the SPRING BASE on the back of the pedal and shut the cover (pedal). Finally,insertthescrew into the pedal guide and tighten it. At this time, be careful not to catch the battery strap in the cover or coil spring. FEATURES • The DD-2 is the first compact digital delay. The DD-2 allows wider range of delay time (12.5ms to 800ms) and frequency response (40Hz to 7kHz/ ^3 dB) than conventional analog system one. • The Pedal Switch has double duty of Effect ON/OFF and Hold ON/OFF. Hold Effect is made attainable by its digital system. • 2 Output system allows to select Mono or Stereo out. • Please be sure to use the AC Adaptor BOSS PSA-series depending on the voltagesystem in your country. ACA-series can not be used, as the DD-2 consumes more courrent (55mA 9V DC) than usual compact effect units. • The battery (one Dry Battery, 9V) will last for 30 minutes to 2 hours (manganese) or 5 to 10 hours (alkaline), depening on the conditions. The use of a BOSS PSA-Adaptor is recommended for a long time performance. • Avoid using this unit in extreme heat or humidity, or where it may be affected by dust.

CONNECTING I AC ADAPTOR BOSS PSA-series • Connect only to this jack to obtain monaural sound. • Mixed sound of the delay and direct in Normal mode. • Only the delay sound in Ste-_ reo mode. AMPLIFIER DD-2 In case requiring only the delay sound (for connecting to Echo Send/Return of a mixer), use only the Direct Output Jack. (^Unplug this unit when it is not to be used. Be sure to take off connecting plug from Input jack.^) AMPLIFIER DESCRIPTION CHECK INDICATOR The Check Indicator enables you to confirm if the Effect is ON or OFF, and as well to check the battery. If the Check Indicator lights up by pressing the Pedal Switch down, Delay Effect is on, and if goes out, Delay Effect isOFF(Normal). *Hold Effect works as long as the pedal is held down. *The battery should be replaced, when the indicator lights but only dimly or does not light Upata"' EFFECT LEVEL This knob controls the output level of the delay sound. Turing this knob clockwise increases the level of the delay sound. With this knob turned fully counterclockwise, the output level of the delay sound is equivalent to that of the direct sound. Also when this knob is turned fully counterclockwise in Normal mode, only the direct sound Is obtained, while no sound is heard from the Main Output in Stereo mode. MAIN OUTPUT JACK Monaural signal (the mixed signal of the direct and delay sounds) is output from this jack. (If the plug is not connected to the Direct Output Jack > FEEDBACK LEVEL This knob decides how many times the delay sound is to be repeated. Turning this knob clockwise increases the number of repetition of delay sound, and turning this knob fully counterclockwise produces single delay sound. OUTPUT igitcil Delay DD-2 i DELAY TIME This knob allows to finely adjust the delay time set with the Mode Selector Switch by from ''X 0.25" to "X1" continueously. Turning this knob clockwise increases the delay time, and counterclockwise decreases it. i INPUT JACK This jack should be connected to an el...
