User manual ROLAND CB-120XL

[. . . ] WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. WARNING - When using electric products, basic precautions should always be followed, including the following: 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] Since you can play chords even when using this effect, you can use it to fatten the sound of your chordal playing as well. You can switch to DELAY or the LOOPER function by positioning this knob. * The scale indications for DELAY and LOOPER are just a general guide. The indicator lights up when DELAY or LOOPER is on and goes out when it's off. You can also switch DELAY on and off using an optional footswitch pedal. When you press the switch twice, the delay time will be set to the time interval at which you pressed the switch. The ON indicator lights up when EFX is turned on, and goes out when EFX is turned off. * Graduations for CHORUS and POLY OCTAVE on a panel are for reference. If you hold down the switch for one second or longer, the delay time will be set to 30 ms. Each time you then press the [REC/PLAY/DUB] switch, the delay time will change over four steps (30 ms/50 ms/ 70 ms/90 ms) to a maximum of 90 ms. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. If the [DELAY/LOOPER] knob is in the LOOPER range, this switch stops the LOOPER or erases the recording. Make sure that all [VOLUME] knobs on the CUBE-60XL BASS/ CUBE-120XL BASS and all the connected devices are set to 0. * Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction. A brief interval (a few seconds) after power up is required before the unit will operate normally. You can switch between use of two types of reverb by changing the position of the knob. you can adjust the intensity of the effect by varying the knob position. The indicator lights up when REVERB is on and goes out when the effect is off. You can also switch REVERB on and off using an optional footswitch pedal. Before switching off the power, lower the volume on all the connected devices and then TURN OFF the devices in the reverse order to which they were switched on. * If you need to turn off the power completely, first turn off the POWER switch, then unplug the power cord from the power outlet. [. . . ] If you turn on the [SHAPE] switch, the lower end will be emphasized and you'll obtain a fat, powerful sound. Additionally, if you raise [MIDDLE] knob or [HIGH-MID] knob, you'll be able to obtain a deeply distorted sound that still retains a great deal of definition, even when playing in a band. By applying compression deeply, and adding a little bit of reverb, you can obtain a sound that sustains well. Also, if you apply chorus when you play melodies, you'll get a sound that has lots of presence. [. . . ]
