Thank you, and congratulations on your choice of BOSS OC-3 SUPER Octave. Before using this unit, carefully read the sections entitled: “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (separate sheet). These sections provide important information con- cerning the proper operation of the unit.
Notes Concerning Use of the OC-3 Please observe the following points to enjoy stable operation of the OC-3. ❍ Except when set to POLY mode (p. 7), the OC-3 is a monophonic-input effects processor. Take care not to play chords with monophonic input.
Panel Descriptions fig.01 1. AC Adaptor Jack Accepts connection of an AC Adaptor (op- tionally available BOSS PSA-Series). By us- ing an AC Adaptor, you can play without being concerned about how much battery power you have left. * As soon as you connect the AC adaptor, the unit is turned on.
* If this indicator goes dim or no longer lights while an effect is ON, the battery is near exhaustion and should be replaced immediately. For instructions on changing the battery, refer to “Changing the Battery” (p. 12). * The CHECK indicator shows whether the effect is being applied or not.
Panel Descriptions fig.02 7. DIRECT LEVEL Knob This adjusts the volume of the direct sound. Turn the knob to the right (clockwise) to in- crease the direct sound. This adjusts the total volume level when the MODE knob (10.) is set to DRIVE. 8.
9. CONTROL Knob This knob’s function changes according to the mode set with the MODE knob (10.). RANGE This functions as a RANGE knob when the MODE knob is set to POLY. This adjusts the range in which the octave effect is applied.
Connections fig.03 OUT 9 V DC/200 mA Guitar Amplifier (Bass Amplifier) For mono use, make the connection to the OUTPUT (MONO) jack. AC Adaptor BOSS PSA-series (option) Electric Guitar Bass Guitar * The GUITAR IN jack is given priority.
* When running the unit on battery power, inserting a plug into the GUITAR IN or BASS IN Jack will automatically switch the unit on. * The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.
Operating the Unit fig.05 1. Turn the effect on. When you have made the necessary con- nections (p. 8), depress the pedal switch to turn the effect on. (the CHECK indicator turns red.) 2. Select the mode with the MODE knob. 3.
<Connection Example> Guitar Amplifier When the OC-3 is in DRIVE mode (p. 7) while DIRECT OUT is connected, the direct sound (with- out the distortion applied) is output from DIRECT OUT. Taking sounds with effects added using a multi-effects processor or other such device and the sounds in DRIVE mode and playing them through multiple amps allows you to produce an extremely low sound with greater separation.
Changing the Battery When the indicator goes dim or no longer lights while an effect is on, it means that the battery is nearly dead and must be replaced. Replace the battery following the steps below. * The use of an AC adaptor is recommended as the unit’s power consumption is relatively high.
Troubleshooting No sound / Low volume: ● Is the OC-3 properly connected to your instrument? Check the connection once more (p. 8). ● Is the volume turned down on any guitar amp or effects device you have connected? Check the settings of the connected device.
