manual abstract
Set the knob so there is no volume difference between the effect and straight guitar sounds. * If this knob is rotated completely counter- clockwise, no sound will be heard. CHECK ENHANCELEVEL MIN MAX 1:1 .:1 RATIO THSHD MIN MAXMIN MAX LEVEL Knob ENHANCE Knob THRESHOLD Knob RATIO Knob This knob adjusts the intensity of the enhance effect that makes the sound clearer and sharper. Rotating the knob clockwise emphasizes the effect. RATIO Knob This knob controls the compression ratio of the limiter. That is, it adjusts how much the limiter should compress those signals above the threshold level. * When it is set to “1:1”, no limiter effect will be obtained. THRESHOLD Knob This knob controls the threshold level (the level at which the compression effect will kick in). Rotating the knob counterclockwise lowers the threshold level. For a detailed explanation about the Ratio and Threshold Level, see “ABOUT THE LIMITER'S ACTION”. MAKING THE CONNECTIONS AC Adaptor (PSA-Series ; Optional) Amplifier OUT 9V DC / 200mA * Inserting a plug into the Input Jack will automatically switch the unit on. *Before connecting or disconnecting any patch cords, be sure all the volume controls in your system are set to minimum. This will help prevent any damage to system components. OPERATING THE UNIT OPERATING THE UNIT When you have made the necessary connections, set the knobs as shown in the illustration. 2. Depress the pedal switch to turn the effect on. (Make sure that the CHECK Indicator lights.) 3. Adjust the Threshold Level (the level at which compression starts) using the THRESHOLD Knob. 4. Adjust the compression ratio using the RATIO Knob. 5. Adjust the intensity of the enhance effect using the ENHANCE Knob. 6. Adjust the LEVEL Knob so there will be no volume difference between the effect and straight bass sounds.

For instance, when the Ratio is set to “2:1”, an input signal that is 6 dB louder than the Threshold Level will be compressed to one half, or 3 dB When it is set to “.:1”, any input signal above the Threshold Level will be compressed to the Threshold Level, then output. THRESHOLD : The Threshold Level is the level at which compression starts to work. When the input signal has reached the Threshold Level, the signal will be compressed at the compression ratio set with “RATIO”, then output. When the input signal is lower than the Threshold Level, it will be output without compression. The following figure shows how the output signal is affected by the settings of the RATIO and THRESHOLD knobs. The following figure shows how the output signal is affected by the settings of the RATIO and THRESHOLD knobs. 2:1 .:1 a Output Level (dBm) Output Level (dBm) b Threshold Level Threshold Level Ratio = a : b Input Level (dBm) Input Level (dBm) CHANGING THE BATTERY CHANGING THE BATTERY Thumbscrew Pedal Spring Base Coil Spring Guide Bush Hole Battery Housing Battery Snap Cord Battery Snap 9V Battery 1. Loosen the thumbscrew at the front of the pedal, then lift the pedal upwards to open the unit. * The thumbscrew can be left in the pedal while changing the battery. 2. Remove the old battery from the battery housing, and remove the snap cord connected to it. 3. Connect the snap cord to the new battery, and place the battery inside the battery housing. * Be sure to carefully observe the battery+s polarity (+ versus -). 4. Slip the coil spring onto the spring base on the back of the pedal, then close the pedal. *Carefully avoid getting the snap cord caught in the coil spring. 5. Finally, insert the thumbscrew into the guide bush hole and fasten it securely.
