User manual ROLAND MKS-30

[. . . ] By using an AC Adaptor, you can play without being concerned about how much battery power you have left. * Use only the specified AC adaptor (PSASeries), and make sure the line voltage at the installation matches the input voltage specified on the AC adaptor's body. Other AC adaptors may use a different polarity, or be designed for a different voltage, so their use could result in damage, malfunction, or electric shock. * As soon as you connect the AC adaptor, the unit is turned on. * If there is battery in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection). 3 4 5 6 7 4 Panel Description 2. [. . . ] RATE Knob Adjusts the rate of the flanging. The flange effect speeds up as you turn the knob to the right. MOMENTARY: The flanger effect is applied only while the MKS-30's pedal is depressed. The STANDARD tone is applied, and flanging starts in the low end. * You cannot input the tempo in MOMENTARY mode. 7 Connections fig. 03 AC Adaptor BOSS PSA-series (option) OUT 9V DC/200mA Electric Guitar Bass Guitar Guitar Amplifier (Bass Amplifier) For monoural use, make the connection to the OUTPUT A (MONO) jack. * The GUITAR IN jack is given priority. 8 Connections * 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. * Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. * If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection). Allow a brief interval to pass before progressing from Step 2 to Step 3 . * If you adjust the RATE knob after completing the settings, the effect then reflects the position of the RATE knob. * You cannot input the tempo in MOMENTARY mode. 12 Setting the RATE by Inputting the Tempo with the Pedal Switch Relationship Between the Flanger and Gate Effects * The gate effect switches on and off 32 times over the period of the flanger effect's rise and fall. * If you want to have the gate working on eighth notes, press the pedal switch at the beginning of the fourth measure of the song you want to have synchronized. fig. 08 Frequency High GATE Effects Low 16 Times 16 Times 16 Times 16 Times RATE Flanger Rise Flanger Fall Flanger Rise Flanger Fall GATE = Flanger Effects Rise Input the tempo Flanger Effects Fall Input the tempo 13 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. * This device consumes considerable power, so use of the AC adaptor is recommended. When powering the unit with batteries, use alkaline batteries. fig. 09 1. Loosen the thumbscrew at the front of the pedal, then lift the pedal upwards to open the unit. * The thumbscrew can be left in the pedal while changing the battery. Remove the old battery from the battery housing, and remove the snap cord connected to it. Connect the snap cord to the new battery, and place the battery inside the battery housing. * Be sure to carefully observe the battery's polarity (+ versus ­). Slip the coil spring onto the spring base on the back of the pedal, then close the pedal. [. . . ] When synching to GATE, please refer to "Relationship Between the Flanger and Gate Effects" (p.
