Printed in Taiwan 2002-6-D3-3C G601723302 BOSS Corporation INSTRUCTIONS 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 effect unit connected between the SEND and RETURN. This makes it possible to reduce the noise of each effect unit whether it is turned on or off. Different 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 effect 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 intérvals or at break. You can use the Pedal Switch effectively as a mute-switch when tuning or changing guitars, as well as for a Normal/ Effect switch. The 9V DC OUT Jack is provided to connect to the optional Parallel DC Cord (PCS-20A) for supplying power to the other 9V effect units. NS-2 Noise Suppressor OUTPUT INPUT <- <-SEND RETURN 4- Noise Suppressor NS-2 p- PANEL DESCRIPTION O 9V DC OUT Jack When an AC adaptor is connected to the 9V DC IN Jack and a Parallel DC Cord PCS-20A is connected to this 9V DC OUT Jack, power supply to the other 9V effect devices is possible. * When being operated on battery, the unit cannot supply power to the connected device. * When using the PSA Adaptor, be sure the total current drew does not exceed 200mA, and when using the RPW-7, 700mA. * Polarity -e- 0 CHECK/MUTE Indicator This indicator lights when the effect (Noise reduction or Mute whichever selected) is on. * This indicator also serves as battery check. When it becomes dimmer or does not light at all, battery replacement is required. Q 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. o REDUCTION Indicator This indicator is lit when the noise reduction function is being engaged. 0 OUTPUT Jack This is to connect to an amplifier. Q SEND Jack Through this jack, the input signal is sent to external effect devices. Q 9V DC IN Jack This is to connect to an AC adaptor (BOSS PSA-120, 220 or 240) or the Power Supply (BOSS RPW-7). For long and secure operation, use an AC adaptor. © 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. Q MODE Selector Switch This selects the Reduction or Mute mode. CHECK/MUTE ^\1NDICAT0R Dark Light MODE (OFF) (ON) REDUCTION Normal Reduction MUTE Reduction Mute on © INPUT Jack Connect an electronic/electric musical instrument such as a guitar. * Plugging in this jack automatically turns the unit on, so disconnect the cord from the jack when the unit is not in use. ® RETURN Jack This is where the signals from the effect units are returned. ® Pedal Switch By pressing the pedal, effect ON/OFF (Normal/ Reduction in the Reduction mode, and Reduc-tion/Mute in the Mute mode) can be controlled. © Thumb Screw Loosen the screw to open the cover for battery replacement. * Do not remove the screw from the cover, or you may loose it. ■ BATTERY REPLACEMENT © Loosen the screw on the pedal to open it. © Take out the battery from the batten/ housing and disconnect the battery snap. © Connect the battery snap to a new battery and replace it to the battery housing. © Place the coil spring to the spring base and close the pedal. * Make sure that the battery snap is not caught in the pedal or coil spring. © Insert the screw into the pedal guide and firmly tighten the screw. t> Use one 9-volt battery. IMPORTANT NOTES AC ADAPTOR To place the NS-2 in the BOSS Carrying Box BCB-6, you need to attach the supplied rubber feet to the BCB-6 shown below. A manganese battery will last for about 5 hours. This depends on the kind of the batte...
