That way, you will be able to continue a performance even if the cord of the AC adapter gets accidently disconnected from the unit.Low knobAdjust the low frequency under 250Hz of the input signal. If the Low knob points at the center, there is no change in the frequency. Turn clockwise to maximum position, there will be +14dB low frequency amplified for signal under 250Hz. Turn anti-clockwise to minimum position, there will be -14dB low frequency lost for signal under 250Hz.Output jackConnect this jack to your amp or to the input of another effect pedal.Pedal SwitchThis switch turns the effect ON/OFF.IndicatorThis indicator shows whether the effect is ON or OFF. When the effect is ON, the indicator lights.* If when you power the pedal with a battery and the indicator goes dim or does not light at all by turning ON the effect, the battery is near exhausted and should be replaced.* The indicator shows only whether the effect is ON or OFF. It does not indicate whether the power to the pedal is ON or not.High knobAdjust the high frequency above 1K Hz of the input signal. If the High knob points at the center, there is no change in the frequency. Turn clockwise to maximum position, there will be +14dB high frequency amplified for signal above 1K Hz. Turn anti-clockwise to minimum position, there will be -14dB high frequency lost for signal above 1K Hz.Level knobAdjusts the level of the output. If turning down the Level knob to minimum position, and the Low knob and the High knob point at the center, the effect output will be the same as the input signal. If turning down the Level knob to minimum position, and turning clockwise the Low knob and the Low knob, the output effect will be bigger than the originally input signal.Input JackThis jack accepts signals from a guitar or other musical instruments, or another effect pedals.* The input jack doubles as the power switch. Power to the unit is turned on when you plug into the input jack; the power is turned off when the cable is unplugged. To prevent unnecessary battery consumption, be sure to disconnect the plug from the input jack when not using the effect pedal.Precautions When Connecting* 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.* Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this pedal. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.* If you will be using the pedal for an extended time, use of an AC adapter is recommended. If you prefer to use a battery, we recommend an alkaline battery.* Raise the amp volume only after turning on the power to all connected devices.* 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.* When operating on battery power only, the pedal’s indicator will become dim when battery power gets too low.
