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.Electric GuitarEnglish
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.
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.
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.
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.”
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.
Delay type eector
* 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,
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.


* 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
* 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
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.

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

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.
