AC Adaptor Jack Accepts connection of an AC adaptor (BOSS PSA-Series; optional). By using 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. * You may find that it is a good idea to keep a battery installed in the unit even while using an adaptor. That way your playing won't be disrupted even if the adaptor is accidentally disconnected. * If you are going to use an AC adaptor\ be sure to use the specified unit (BOSS PSA-Series). Use of any other adaptor may result in damage; malhmc-tion or electric shock. In addition, if you are not going to be using it for an extendedperiod of time, disconnect the AC adaptor from the AC outlet 2. CHECK Indicator This LED indicates whether the effect is ON/ OFF, and also doubles as a battery check. The indicator lights when the effect is ON. If this indicator goes dim or no longer lights while the effect is ON, the battery is near exhaustion and should be replaced immediately. 3. OUTPUT Jacks A(MONO)/B The output jacks are used to connect the unit to amplifiers or other devices. The harmony parts set with the VOICE A and B knobs will be output to OUTPUTS A/B. To output a monaural signal, use only the A(MONO) jack (VOICEs A/B will be output through A(MONO)). 4. Pedal Switch This switch turns the unit ON/OFF. 5. Thumbscrew This thumbscrew is loosened to open the pedal, allowing battery replacement. For instructions on how to replace the battery, please refer to "CHANGING THE BATTERY" on page 16. 6. INPUT Jack This jack accepts input signals (coming from a guitar, some other electric or electronic musical instrument, or another effects unit). * When you direct the output signal from an external effects unit to the HR-2, be sure to input the guitar sound directly to the DETECTOR IN Jack. If you connect the output signal of the other effects unit without using DETECTOR IN, the pitch of the harmony will be inaccurate. * The INPUT Jack also serves as the power switch while using the unit on battery power. Power is turned on whenever a plug is inserted into the INPUTJack, and is turned off when the plug is disconnected. When not using the unit, you should disconnect any cord connected to the INPUT Jack. 7. DETECTOR IN Jack The input jack is used to detect the pilch of a musical instrument. When you connect an effects unit before the HR-2, be sure to input the guitar signal directly into the DETECTOR IN Jack. * For a detailed explanation on the connections using the /yDETECTOR IN Jack", see page 12 "HOW TO USE THE DETECTOR IN JACK". 7 EFFECT LEVEL Knobs A/B VOICE Switches A/B I CHECK L.................... ........, w E.LE|VEL VOIOEH VOltE@ r a^ia KEY Rn1l3»1FcRn Q MIN MAX -OCT +OCT -OCT +OCT 4- outputI f BE3 Id c _____ * ■ bisi MjuiBui KEY Switch illlllilllKnllllli** These knobs are used to adjust the volume of voices (harmony parts) A and B. * I fan E. LEVEL Knob (A/B) is rotated completely counterclockwise> no effect sound will be beard. These knobs adjust the harmonic interval of voices A and B. You can select any of the following settings: a 3rd, 4th, 5th, 6th or 1 octave. For a detailed explanation, see page 13 "HOW TO SET THE VOICE SWITCHES A/B". Regarding the harmony parts that are output, see page 14 "ABOUT THE SCALE OF THE EFFECT SOUND". This knob allows you to select the key that corresponds to the song to be played. The HR-2 then creates one or two harmony parts appropriate for each individual input sound. * If you fail to select the proper key for the song, the harmony parts will not be of the correct harmonic interval. MAKING THE CONNECTIONS * Inserting a plug into the INPUT Jack will automatically switch the unit on. * Before connecting or disconnecting any patch cords, be sure all the volume controls in your system are set to minimum; this will help prevent any damage to system components. The following illustrates how to connect a guitar directly to the HR-2. If you wish to connect another effects unit before the HR-2, refer to "HOWTO USE THE DETECTOR IN OPERATING THE UNIT We recommend that you use a tuner to make sure that your instrument is perfectly tuned. 1. When you have made the necessary connections, set the knobs as shown in the illustration. 2. Depress the pedal switch to turn the effect on. (Be sure the CHECK Indicator lights.) 3.
