Owners Manual
Before using this unit, carefully read the sections entitled: USING THE UNIT SAFELY and IMPORTANT NOTES (supplied on a separate sheet). These sections provide important information concerning the proper operation of the unit. Additionally, in order to feel assured that you have gained a good grasp of every feature provided by your new unit, this manual should be read in its entirety. The manual should be saved and kept on hand as a convenient reference.
Precautions When Connecting * To prevent malfunction and equipment failure, always turn
down the volume, and turn off all the units before making any connections.
* 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 bass amp last.
When powering down: Turn off the power to your bass amp first.
* Immediately after the unit is powered-on, the effect is on.
Use of Battery * A battery was installed in the unit before it left the factory. The
life of this battery may be limited, however, since its primary purpose was to enable testing.
* If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in USING THE UNIT SAFELY and IMPORTANT NOTES (supplied on a separate sheet).
* When operating on battery power only, the units indicator will become dim when battery power gets too low. Replace the battery as soon as possible.
* Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and damage.
* The use of an AC adaptor is recommended as the units power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.
Changing the Battery 1. Hold down the pedal and loosen the thumbscrew, then
open the pedal upward. * The pedal can be opened without detaching the thumbscrew
completely.

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 batterys polarity (+ versus -).
4. Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal.
* Carefully avoid getting the snap cord caught in the pedal, coil spring, and battery housing.
5. Finally, insert the thumbscrew into the guide bush hole and fasten it securely.

Main Features
Panel Descriptions
This is a dedicated compressor for bass that uses Bosss cutting-edge MDP digital technology to make your sound consistent without impairing the fundamental frequency of your instrument. A gain reduction indicator is provided so that you can see the results of compression. The internal operating voltage of 18 V means that you can confidently connect even high-output basses to this unit, which is designed specifically for bass input. * An internal voltage boost circuit is used to provide 18 V operation. As the AC adaptor, you can use the standard PSA adaptor thats common to the BOSS compact effect series.
INPUT jack This jack accepts signals coming from a bass or other musical instrument, or another effects unit.
* 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 effects unit.
Bass amplifier
OUTPUT jack Connect this jack to your amp or to the input of another effect unit.
Pedal switch This switch turns the effect on/off.
Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery.
* For instructions on changing the battery, refer to Changing the Battery.
Bass
AC Adaptor (PSA series: optional)
DC IN jack Accepts connection of an AC Adaptor (PSA series; optional). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.
* Use only the specified AC adaptor (PSA series; sold separately), and connect it to an AC outlet of the correct voltage. Do not use any other AC adaptor, since this may cause malfunction.
* If the AC adaptor is connected while a battery is installed, the power supply is drawn from the AC adaptor.
* We recommend that you keep batteries installed in the unit even though youll be powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.
LEVEL knob
Adjusts the output level.
RELEASE knob Adjusts the consistency of the sound. Turning this knob toward the left shortens the release time, making individual notes more prominent. Turning the knob toward the right produces a smoother and more connected sound.
Gain Reduction Indicator
Indicates the amount of compression when the compressor is operating. The greater the compression effect, the larger number of indicators are lit.
RATIO knob
Adjusts the amount of compression (compression ratio) that is applied to the input signal. Turning this knob all the way to the left produces a compression ratio of 1:1 (no compression); turning it toward the right increases the compression ratio, producing a greater effect.
Adjusts the signal level at which the compression begins to take effect. As you turn this knob toward the left, the effect begins to apply at a lower input signal level.
THRESHOLD knob
CHECK indicator This indicator shows whether the effect is on or off, and also doubles as the battery check indicator. The indicator lights when the effect is on.
* If youre powering the unit with a battery and the CHECK indicator goes dim or doesnt light at allwhen you try to turn the effect on, the battery is near depletion and should be replaced. For instructions on changing the battery, refer to Changing the Batte
