The OC-2 enables you to extract the notes one octave lower and two octaves lower, then spontaneously mix these two types of sounds with a direct sound at the levels you desire. Therefore you can create various kinds of sounds such as a heavy powerful sound, bass sound and octave unison sound. Moreover, these processed signals perfectly follow the envelope of the direct sound, which makes it easy to create a realistic bass sound. Besides, the OC-2 runs with a small power consumption and allows an exceptionally stable operation. NAME AND FUNCTIONS BATTERY ELIMINATOR JACK if OCT2 OUTPUT JACK PEDAL SWITCH Octaver _^ OC-2 INDICATOR OCT1 DIRECT * LEVEL INPUT JACK THUMB SCREW OCTAVE 1 This knob adjusts the volume of the sound one octave lower than a direct sound. Turn it clockwise to increase the volume and counterclockwise to decrease. OCTAVE 2 This knob adjusts the volume of the sound 2 octaves lower. Turn it clockwise to increase the volume and counterclockwise to decrease. DIRECT LEVEL This knob adjusts the volume of the normal sound with an effect. INPUT JACK Connect the plug to this INPUT jack to turn the OC-2 on. Keep the plug off while the OC-2 is not in use. OUTPUT JACK The OC-2 generates low noise and hum as a result of its low impedance output to the amplifiers. BATTERY ELIMINATOR JACK Connect the BOSS AC Adaptor to this jack. INDICATOR By the LED indicator you can see whether the unit is on or off, and also check the battery. ’Replace with a new battery if the indicator becomes dimmer or fails to light. PEDAL SWITCH Due to the unique FET switching system, the OC-2 does not make a click or a pop noise. THUMB SCREW Do not remove the screw from the unit when replacing the battery. NOTE *Use the BOSS AC Adaptor for AC operation. CONNECTING OC-2 f AMPLIFIER * Avoid using the OC-2 in exessive heat or humidity, or where it may be affected by dust. f TO BATTERY ELIMINATOR JACK BOSS AC ADAPTOR Power is on while the plug is being connected to the BOSS OC-2 input jack. KEYBOARD (Remember to disconnect the plug from the INPUT jack when the OC-2 is not to be used. OPERATIONS OCT2 After connecting all the cords required, set all the knobs on the panel as shown beside. OCT1 Step on the PEDAL SWITCH, and the check LED lights up indicating “EFFECT is on”, and goes out indicating "EFFECT is off”. This check LED is also used to check the battery. If the LED fails to light or becomes dimmer, the battery should be replaced. Adjust the three knobs OCTAVE 1, OCTAVE 2, and DIRECT LEVEL to make your own sound. *lf you set the knobs all to 'O', there is no sound coming out even if the PEDAL SWITCH is on. BATTERY REPLACEMENT AND PRECAUTIONS 9V BATTERY BATTERY CONNECTOR PEDAL(COVER) THUMB SCREW SPRING BASE COIL SPRING PEDAL GUIDE BATTERY STRAP BATTERY HOUSING • USE ONE 9-VOLT BATTERY. © Loosen the screw of the PEDAL and open it. ©Take out the battery from the BATTERY HOUSING and replace with a new one. ©Set the COIL SPRING onto the SPRING BASE and shut the COVER. Please be careful not to catch the BATTERY STRAP with the COVER or the COIL SPRING. © Insert the screw into the PEDAL GUIDE and tighten it. CAUTIONS •When you do not use the OC-2 for long periods, remove the battery to prevent leakage. •If battery voltage drops, effect becomes inferior or no sound is produced. To prevent that, replace the battery. AC ADAPTOR (OPTION) BOSS ACA-120 FOR 117V AC BOSS ACA-240 FOR 240V AC • Be sure to keep the batteries securely connected even while using the AC Adaptor. ’Even if AC Adaptor cord comes out during performance, the OC-2 will continue to operate if the battery is connected. •Keep the plug off the INPUT JACK when the OC-2 is not in use. Use the BOSS AC Adaptor to obtain satisfactory AC operation.
