When switched off, the sound input to the INPUT jack is output without change. When set to “SLOW” When set to “FAST” Off Lit SLOW/FAST Pedal Switches the rotor’s rotation speed each time the pedal is pressed. 8 Operating the RT-20 Panel Operation For this description of using the pedals, first press the EFFECT ON/OFF pedal to switch on the effect (ON/OFF indicator lit), and press the SLOW/FAST pedal to switch the setting to SLOW (SLOW/FAST indicator off). In addition, set the knobs to the positions shown in the figure. fig.080 1. Set the DRIVE TYPE switch on the rear panel to match the type of instrument being used. Refer to “Making the Connections” (p. 5–p. 6). 2. Use the MODE knob to select the desired rotary speaker effect from the four types. 3. Turn the OVERDRIVE knob to adjust the amount of drive applied. 4. Adjust the EFFECT ON volume by turning the EFFECT LEVEL knob. While the settings described above produce a rotary speaker sound, The RT-20 allows you to control the following factors that are difficult to control with conventional rotary speakers. • Adjust the balance of the HORN rotor and BASS rotor volume • Adjust the rotor’s rotation speed • Adjust the rate at which the speed changes when switching from SLOW to FAST and FAST to SLOW • Mix the direct sound 2 4 3 9 Operating the RT-20 Adjusting the Balance of the HORN Rotor and BASS rotor volume You can adjust the balance in volume from the horn rotor and bass rotor inside the rotary speaker with the BALANCE knob. fig.081 Adjusting the Rotor’s Rotation Speed You can adjust the rotor rotation speed using the SLOW SPEED and FAST SPEED knobs. Turning these knobs to the center position sets the rotor speed to the standard rotation speed. fig.082 Adjusting the Rate at Which the Speed Changes When Switching from SLOW to FAST and FAST to SLOW You can adjust the rate at which the rotation changes from slow to fast and vice versa with the RISE TIME knob. Turn the knob to the left to slow down the rate of change; turn the knob to the right to increase the rate. When this knob is at the center position, the rise time is set to the standard setting. fig.083 Mixing the Direct Sound If you want to retain the nuance of the direct sound used by the guitar or other instrument, you can add the direct sound using the DIRECT knob. * If you want to reproduce the regular rotary speaker sound, turn this knob completely to the left to shut off the direct sound. fig.084 Operating the SLOW/FAST Pedal You can switch the rotor’s rotation speed by pressing the SLOW/FAST pedal. When set to SLOW, the SLOW/FAST indicator is switched off; the indicator is lit when the speed is set to FAST. 10 Operating the RT-20 Operating the BRAKE You can use the brake to stop the rotation of the rotor. Pressing both of the pedals simultaneously stops the rotation of the rotor. The SLOW/FAST indicator flashes rapidly while the brake is on. The time required for the rotor to come to a stop after the BRAKE is activated changes according to the position of the RISE TIME knob. The time required for the rotor to stop increases as the knob is turned further left from the center position; turning the knob to the right of the center position decreases the time required for the rotor to stop. fig.090 To cancel the BRAKE, pressing either the light pedal or both left and right pedals simultaneously. The rotor always faces directly in front when stopped. Controlling the RT-20 with an Expression Pedal You can connect an optional expression pedal (such as the Roland EV-5) to the rear panel SPEED (EXP PEDAL) jack and use the pedal to control the rotor’s rotation speed in real time. fig.100 With the expression pedal fully released, the RT-20 switches to the value set with the SLOW SPEED knob; depressing the pedal all the way switches the RT-20 to the value set with the FAST SPEED knob. * The SLOW/FAST indicator flashes when an expression pedal is connected. * Operation of the SLOW/FAST pedal is disabled while the expression pedal is connected. * You can also use an expression pedal to operate the BRAKE. * Use only the specified expression pedal (EV-5; sold separately). By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit. Both pressed simultaneously Flashes rapidly Expression pedal (Roland EV -5, etc.) 11 Front Panel Names of Things and What They Do RISE TIME Knob This adjusts the rate at which the rotation changes from slow to fast and vice versa. When this knob is at the center position, the rotary speaker rotation changes at the standard rate. MODE Knob Use this to select the rotary speaker effect from the four available types. “Mode List” (p. 13) BALANCE Knob This adjusts the balance in volume from the horn rotor and bass rotor inside the rotary speaker with the BALANCE knob. * When MODE is set to IV, this knob adjusts the intensity of the UNI-V effect. OVERDRIVE Knob This knob adjusts the depth of the overdrive effect. Switch to OFF when overdrive is not being ...
