This will help in preventing malfunction, and damage to speakers. • Do not force the unit to share the same power outlet as one used for distortion producing devices (such as motors, variable lighting devices). Be sure to use a separate power outlet. Concerning placement • Placing the unit near power amplifiers or other equipment containing large transformers may induce hum. Maintenance • For everyday cleaning, wipe the unit with a soft dry cloth, or one that is dampened slightly. To remove dirt that is more stubborn, wipe using a mild, neutral detergent. Afterwards, make sure to wipe thoroughly with a soft cloth. • Never apply benzene, thinners, alcohol or any like agents, to avoid the risk of discoloration and deformation. Other Precautions • Protect the unit from strong impact. • A certain small amount of heat will be radiated from the unit, and thus should not be considered abnormal. • Before using the unit in a foreign country, check first with your local Roland Service Station. 3 ■ PANEL DESCRIPTION «Front Panel» O Input Jack Connect a guitar to this jack. 0 Volume Control Knob This adjusts the input level of each CH1 and CH2. Clockwise rotation will increase the input level, creating distorted sounds. 0 Master Knob This adjusts the volume of each CH1 and CH2. * Adjust the depth of distortion with the Volume Control Knob and the volume with the Master Knob. 0 Channel Indicator The indicator of the selected channel, CH1 or CH2, will be lit. lOOHz- 1.6kHz 0 4 Band Parametric Equalizer This controls the sound of CH1. Clockwise rotation (O) will boost frequencies, while counterclockwise rotation (O) will cut them. The variable range for boosting and cutting is from -20 to +20dB. LOW: The volume of lower frequencies (lower than 100 Hz) is controlled. LOW-MID: The volume of middle freauencies (100Hz to 1,6kHz) is controlled. Select the frequency to be boosted or cut with FREQ, then set the amount of boosting or cutting with LEVEL. HIGH-MID: The volume of middle frequencies (500Hz to 8kHz) is controlled. Select the frequency to be boosted or cut with FREQ, then set the amount of boosting or cutting with LEVEL. HIGH: The volume of higher frequencies (higher than 8kHz) is controlled. 0 Mode One of the five modes can be selected. It determines the basic sound of CH1. DRIVE I : This is a simulation of a two-speaker tube guitar amplifier. Clear sounds can be obtained. DRIVE II : This is a simulation of a large size tube guitar amplifier that is often used for Rock or Fusion music. Distorted sound can be obtained. DRIVE HI: This is a simulation of three stage stacking of large tube amplifiers often used for Heavy Metal music. Hard distorted sound can be obtained. DISTI : Normal distortion sound can be obtained. DISTII: Unique distortion sound by equalizing effect is obtained. 4 o Channel Selector Switch e Mode Selector Switch Use this switch to select CH1 or CH2. When the switch is One of the four modes can be selected. It determines the pressed down, CH2 is selected. basic sound of CH2. 0 3 Band Parametric Equalizer This controls the sound of CH2. Clockwise rotation (O) will boost frequencies, while counterclockwise rotation (O) wiH cut: them. The variable range for boosting and cutting is from -20 to +20dB. LOW: The volume of lower frequencies (lower than 100 Hz) is controlled. LOW-MID: The volume of middle frequencies (250Hz to 4kHz) is controlled. Select the frequency to be boosted or cut with FREQ, then set the amount of boosting or cutting with LEVEL. HIGH: The volume of higher frequencies (higher than 8kHz) is controlled. FLAT: Flat frequency sound is obtained. CUTTING: Cl ear sound is obtained. It is ideal for cutting performance. Electric acoustic guitar like sounds can be generated by using an electric guitar. DRIVE: This is a simulation of a two-speaker type tube guitar amplifier. Clear sounds can be obtained. DIST: Normal distortion sound can be obtained. * In the FLAT or CUTTING mode, the simulation circuit in the speaker section does not function. ® Monitor Output Level Knob This controls the output level from the Monitor Output Jack. 0 Power Switch, Power Indicator The Power Indicator lights up when the unit is switched on. * This unit does not work for a while after being switched on. This is for protecting the internal circuits. 5 «Rear Panel 11 © Input Jack Connect a guitar to this jack. * When both Input Jacks on the front and rear of the unit are used at the same time, the one on the front panel will work. © Buffer Out Jack Through this jack, an exact copy of the signal from the guitar is output. Use this to send guitar signal to the other device or to connect a tuner. © Send/Return (L/R) Jacks These are input and output jacks for connecting an effect unit. Connect the input of the effect unit to the Send Jack, and connect the output of the effect unit to the Return Jack. If you use an effect unit with stereo output, connect each ou...
