You may find helpful the following booklet prepared by the Federal Communications Commision: "How to Identify and Resolve Radio-TV Interference Problems" This booklet is available from the U.S. Government Printing Office, Washington, D.C., 20402, Stock No. 004-000-00345-4. 4-output Q_ iff, <-output Q input 4- SUPGR Chorus CH-1 ■Bl ■ PANEL DESCRIPTION EQ RATE DEPTH SUPGR Chorus CH-1 o AC Adaptor Jack Connect an optional AC adaptor (BOSS PSA-120, 220 or 240) to this jack for AC operation. * Using the AC adaptor, you can enjoy long and secure operation without having to worry about battery's life. A manganese battery lasts about 20hours. 0 Check Indicator This lights up when the effect is turned on, and therefore can be used as an effect on/off indicator. * The Check Indicator also serves as battery check. When it becomes dimmer or does not light at all, battery replacement is required. 0 Effect Level Knob This sets the mixing level of the effect sound (whose pitch is changing) to the normal sound. Clockwise rotation CO) increases the volume of the effect sound, while counterclockwise rotation CO) decreases it. O Equalizer Knob This controls the tone of the effect sound. Clockwise rotation CO) boosts higher frequencies and counterclockwise rotation CO) cuts them. © Modulation Rate Knob This sets the rate of the chorus effect. Clockwise rotation CO) quickens the rate and counterclockwise rotation CO) slows down. @ Modulation Depth Knob This sets the depth of the chorus effect. Clockwise rotation CO) deepens the effect and counterclockwise rotation CO) creates the opposite effect. O Output Jacks A/B Connect an amplifier to these jacks. For monaural output, use only Output A. © Input Jack Connect an electric/electronic musical instrument such as a guitar to this jack. * Plugging in this jack will automatically switch the unit on. Be sure to disconnect the cord from this jack when the unit is not to be used. © Pedal Switch Pressing the pedal turns on or off the effect. © Thumb Screw Loosen this screw to open the cover for battery replacement. * Do not remove the screw from the cover so that you will not lose it. CONNECTIONS Amplifier Amplifier AC Adaptor Jack Output B ■=301 Output A For monaural output, use only Output A.

Use one 9-volt battery * For monaural output, use only Output A. Output A sends the mixture of the effect and normal sounds. * When using the CH-1 in stereo output. OUTPUT A: Only effect sound (whose pitch is changing) is output. OUTPUT B: Only normal sound is output. The CH-1 adopts the space compounding stereo system, therefore, the effect will vary depending on the distance between two speakers (L/R). Try playing the instrument to check how it actually sounds like. If you lower the equalizer or effect level, the pan will be moved to Output B. * Sound may be distorted if a guitar of large output is used. If this happens, decrease the guitar’s volume or use a limiter. ■ IMPORTANT NOTES • If the battery voltage drops (the Check Indicator lights dimmer), various symptoms are shown, such as the effect becomes weak, no sound is produced, etc. To prevent that, replace the battery immediately. • Make sure that the polarity of the battery is correct when connecting the battery. • When the unit is not to be used for a long period of time, remove the battery to prevent battery leakage. • Be sure to use the AC adaptor BOSS PSA-120, 220 or 240 depending on the voltage system in your country. • Be sure to keep the battery securely connected even while using the AC adaptor, then the unit will continue to operate even if the AC adaptor cord comes out during performance. • Plugging in the Input jack will automatically switch the ...
