User manual ROLAND ODB-3 MANUAL 2

[. . . ] By using an AC Adaptor, you can play without being concerned about how much battery power you have left. 3 6 * 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, malfunction or electric shock. [. . . ] When rotated fully counterclockwise (or clockwise), only the Dry (or Overdrive) sound will be obtained. BALANCE Knob GAIN Knob GAIN Knob This knob adjusts the gain of the Dry or Overdrive sound. When you are using Dry sounds, this knob can adjust the amount of boost without distorting the sound. When you are using Overdrive sounds, the GAIN knob adjusts the depth of the distortion. Clockwise rotation increases the gain. LEVEL Knob This knob adjusts the level of the effect sounds. Set the knob so there is no volume difference between the effect and straight guitar sounds. 6 MAKING THE CONNECTIONS AC Adaptor (PSA-Series ; Optional) OUT 9V DC / 200mA Electric Bass Amplifier 7 * Inserting a plug into the INPUT Jack will automatically switch the unit on. * 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). * Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. When powering up: Turn on the power to your guitar amp last. When powering down: Turn off the power to your guitar amp first. * 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. * When operating on battery power only, the unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible. * The CHECK indicator shows whether the effect is being applied or not. It does not indicate whether the power to the device is on or not. 8 OPERATING THE UNIT 3. Adjust the output balance between the 6 5 3 4 Dry and Overdrive sounds using the BALANCE Knob. 4.
