INPUT jack

This jack accepts input signals (coming from a guitar, some other musical

instrument, or another eects unit).

* The INPUT jack also serves as the power

switch. Power is turned on whenever

a plug is inserted into the INPUT jack,

and is turned o when the plug is

disconnected. When not using the

unit, you should disconnect any cord

connected to the INPUT jack.

9 V DC OUT jack

When an AC adapter is used, you can connect a PCS-20A parallel DC cord (optional)

to supply power to eects processors and other PSA adaptor-compatible gear.

* Power cannot be supplied from the DC OUT jack when the NS-2 is

running on batteries.

* If you use the PCS-20A to supply power to devices that are

compatible with PSA adaptors, make sure that the total

current consumption of all devices (including the NS-2)

does not exceed the maximum output current of the PSA

series unit you’re using.

REDUCTION indicator

This indicator os lit when the noise reduction function is being engaged.

The BOSS NS-2 is a completely new type noise suppressor that features the SEND and RETURN jacks.

The NS-2 can detect the instrument signal separately from the noise comes from each eect unit connected between the SEND and RETURN. This makes it possible to reduce the noise of each eect unit whether it is turned on or o.

Dierent from the past noise suppressing system, the NS-2 features a high-quality VCA and high-speed envelope-detecting circuits, and the expander starts its function when the volume of the instrument becomes lower than the

threshold level. Therefore, natural noise reducing eect is obtained without deteriorating the sound quality and expression.

The NS-2 works as a noise-gate unit, cutting the noise and hum that occur between song intervals or at break.

You can use the Pedal Switch eectively as a mute-switch when tuning or changing guitars, as for a Normal/Eect switch.

The 9 V DC OUT jack is provided ti connect to the optional Parallel DC Cord (PCS-20A) for supplying power to the other 9 V eect units.

OUTPUT jack

The output jack is used to connect the unit to

ampliers or other devices.

Guitar Amplier

DC IN jack

Accepts connection of an AC Adaptor (PSA series; sold separately). By using an AC Adaptor, you can play

without being concerned about how much battery power you have left.

* We recommend that you keep batteries installed in the unit even though you’ll be powering it

with the AC adaptor. That way, you’ll be able to continue a performance even if the cord of the

AC adaptor gets accidentally disconnected from the unit.

* Use only the specied AC adaptor (PSA-series).

* If the AC adaptor is connected while power is on, the power supply is

drawn from the AC adaptor.

CHECK/MUTE indicator

This indicator lights when the eect (Noise reduction or Mute whichever

selected) is on.

This indicator also serves as battery check.

* If this indicator goes dim or no longer lights while an eect is ON, the

battery is near exhaustion and should be replaced immediately.

* The CHECK indicator shows whether the eect is on or o, and

indicates the dierent functions. It does not indicate whether the

power to the device is on or not.

THRESHOLD knob

This sets the threshold level where the noise suppression starts working.

Adjust it depending on the signal level and noise level, and when too low,

counterclockwise.

Pedal Switch

By pressing the pedal, eect ON/OFF (Normal/Reduction in the Reduction mode

and Reduction/Mute in the Mute mode) can be controlled.

SEND jack

Through this jack, the input signal is sent to external eect devices.

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.”

RETURN jack

This is where the signals from the eect units

are returned.

Main Features

Operating the Unit

1. Make all the necessary connections.

* You can also set up the NS-2 at the end of the other eects, but the

example setup may be more eective.

Bass

* Do not connect delay or reverb eects

between the Send and Return. Connect

them between the NS-2 and an amplier.

2. Set the controls on the panel as

shown below.

3. Push the pedal switch and make sure the

check indicator lights up.

* When the check indicator is lit, noise reduction is on and when it is dark,

normal.

4. Turn on the eect device to be used,

then set the threshold knob so that the

reduction indicator will light while not

playing and the noise will not be natural.

* Try making the decay toward the end sound natural.

5. Normally, set the DECAY knob to the MIN

position, but if the sound does not fade out

naturally, rotate it clockwise.

6. Set the mode selector switch to reduction

or mute.

* REDUCTION position allows you to select Normal or

reduction, and the MUTE position allows you to keep

reduction on use Mute occasionally.

IMPORTANT NOTES

* A manganese battery will last for about 5 hours. This depends on the

kind of the battery and how you use the unit.

* If the battery voltage drops (the Check/Mute indicator becomes dimmer),

various symptoms are shown, such as the eect becomes weak, no sound

is produced, etc. To prevent that, replace the battery immediately.

* When the unit is not to be for a long period of time, remove the battery

to prevent problems caused by battery leakage.

* Plugging in the INPUT jack automatically turns on the unit. So disconnect

the cord from the INPUT jack when the unit is not in use.

* Avoid using this in extreme heart or humidity, or where it may be

aected by dust.

AC Adaptor

* Be sure to use the AC adaptor BOSS PSA-120, 220 or 240 depending on

the line voltage system in your country.

* DO not use the same socket used for any noise generating or large power

consuming device such as a motor, variable lighting system, etc.

* Connect the AC adaptor to the 9 V DC IN jack on the unit rst, then to

the socket.

* Be sure to keep the battery securely connected even while using the AC

adaptor, then the unit will continue to operate even if the AC adaptor

cord comes out during performance.

* When the unit is not in use, disconnect the AC adaptor from the socket.

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 uid 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 unit’s 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.

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 battery’s 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.

9 V Battery

* To prevent malfunction and equipment failure, always turn down the volume, and turn o all the units before making any

connections.

* Before turning the unit on/o, always be sure to turn the volume down. Even with the volume turned down, you might

hear some sound when switching the unit on/o. However, this is normal and does not indicate a malfunction.

DECAY knob

This sets the time needed for the sound to fade out when the input signal

becomes lower than the set threshold level.

Rotating it clockwise makes the decay time longer. Normally, set this to the MIN

position.
