manual abstract
Two completely different phase effects are optional just by changing the position of the knob. Adopting antilogarithm circuit in the filter, the PH-2 gives smooth modulation effect. The indicator lights up when the effect is on, so that you can at a glance tell whether the effect is on or off. INDICATOR* RATE KNOB DEPTH KNOB OUTPUT JACK Phaser PH-2 AC ADAPTOR JACK MODE SELECTOR RESONANCE KNOB INPUT JACK PEDAL SWITCH THUMB SCREW AC ADAPTOR JACK Connect an AC Adaptor (BOSS ACA-120, 220 or 240) to this jack, and the PH-2 operates from the mains. RATE KNOB This knob controls the rate of the phase shift effect. At the fully clockwise position, phase effect of 100ms is obtained. As you rotate the knob counterclockwise, the rate slows down up to 14s. OUTPUT JACK Through this jack, signal is fed to an amplifier. PEDAL SWITCH Pressing this pedal turns on the effect, and pressing it again turns the effect off. * Adopting FET electronic switch,this is free from click noise. INDICATOR This indicator lights up when the effect is turned on, therefore you can tel! at a glance whether the effect is on or off. This also serves as battery check. If the indicator becomes dimmer or does not light at ail, battery replacement is required. DEPTH KNOB This knob controls the depth of phase shift effect. Rotating this clockwise deepens the effect. RESONANCE KNOB This knob controls the amount of feed back signal. Rotating this clockwise emphasizes the phase shift effect, therefore the created sound will be more unusual. MODE SELECTOR In the Mode I position, phase sound, deeply swelling from high frequency to low, is obtained. The Mode II is a phase sound with sharp phase shifting effect. INPUT JACK Connect a guitar or other electronic musical instrument to this jack. THUMB SCREW Loosen this screw to open the pedal for battery replacement. * Do not remove the screw from the pedal, or you may lose it. IMPORTANT • When operating the PH-2 from AC !ine, use the BOSS AC Adaptor. • Avoid using the PH-2 in extreme heat, humidity or where it may be affected by dust.

OPERATION 3. 1. Make sure that al! connections are properly made, then set the panel as shown left. Press the pedal to turn the effect on. Here, if the indicator does not light, press the pedal once again. The indicator can also be used as battery check. If it becomes dimmer or does not light at all, replace the battery.

CAUTIONS FOR REPLACING AND HANDLING BATTERY PEDAL (COVER) 9V BATTERY BATTERY CONNECTOR THUMB SCREW SPRING BASE COIL SPRING ■PEDAL GUIDE BATTERY HOUSING BATTERY STRAP BATTERY REPLACEMENT USE 9V BATTERY • Loosen the screw and open the Pedal. • Take out the battery from the Battery Housing and pull up the Battery Strap. • Attach the Battery Strap to the new battery, and place it in the Battery Housing. *Make sure that the Battery Strap is not caught in the Pedal or Coil Spring. • Put the Coil Spring to the Spring Base and close the Pedal. • Firmly tighten the screw. PRECAUTIONS • When the PH-2 is not in use for a long period, remove the battery to prevent the trouble caused by the battery leakage. • If the battery voltage drops, effect becomes inferior or no sound is produced. To prevent that, replace the battery. AC ADAPTOR (OPTION) • Be sure to keep the battery securely connected even while using the AC Adaptor, then the PH-2 will continue to operate even if the AC Adaptor cord comes out during performance. • Unplug the cord from the INPUT jack when the PH-2 is not in use to avoid wasting the battery.
