Boss NS-2 Specification

The Boss NS-2 Noise Suppressor is a compact and highly efficient pedal designed to eliminate unwanted noise and hum from guitar and bass signal chains without compromising the integrity of the original audio signal. It features an intuitive design that seamlessly integrates into any pedalboard setup. At its core, the NS-2 employs a proprietary noise detection circuit that effectively preserves the natural decay of notes, ensuring a clean and noise-free output.

The pedal includes essential controls such as Threshold and Decay, allowing users to fine-tune the noise reduction process according to their specific requirements. The Threshold control sets the level at which the noise suppression begins, while the Decay knob adjusts the time it takes for the noise reduction to take effect after the signal drops below the threshold.

Additionally, the NS-2 offers a unique Send/Return loop, enabling users to isolate and silence specific sections of their effects chain, further enhancing its versatility and effectiveness. This loop is particularly useful for managing noise from high-gain pedals or amplifiers. The pedal operates using a standard 9V power supply and features Boss's renowned durability and reliability, ensuring it withstands the rigors of live performances and extensive use.

With its compact dimensions, the Boss NS-2 fits easily into any rig, making it an essential tool for musicians seeking to maintain a pristine sound without sacrificing tone. Its ability to deliver transparent noise suppression has made it a staple for guitarists and bassists worldwide.

Boss NS-2 F.A.Q.

How do I connect the Boss NS-2 to my pedalboard?

To connect the Boss NS-2 to your pedalboard, use the 'Send' and 'Return' jacks to create a loop. Connect your noisy pedals (like distortion or overdrive) between the 'Send' and 'Return'. Connect your guitar to the 'Input' and your amp to the 'Output'. This setup helps eliminate noise from your pedals.

Why is my Boss NS-2 not reducing noise effectively?

Ensure that the 'Threshold' and 'Decay' knobs are set correctly. The 'Threshold' should be set just above the noise level, and the 'Decay' should be adjusted to control how quickly the noise gate closes. Also, verify that the cables and connections are secure.

What is the function of the 'Decay' knob on the Boss NS-2?

The 'Decay' knob on the Boss NS-2 controls the time it takes for the noise gate to close after the signal falls below the threshold. A shorter decay will result in a quicker gate closure, while a longer decay allows for a more natural sound as the note sustains.

Can the Boss NS-2 be used in front of the amp and in the effects loop simultaneously?

Yes, the Boss NS-2 can be used both in front of the amp and in the effects loop simultaneously by utilizing its send/return loop feature. Connect your pedals that are before the amp to the 'Input/Output' and those in the effects loop to the 'Send/Return'.

How can I power the Boss NS-2 pedal?

The Boss NS-2 can be powered using a 9V battery or a 9V DC power adapter. If using a power adapter, ensure it is a Boss PSA adapter or a compatible power supply with center-negative polarity.

Is it possible to power other pedals using the Boss NS-2?

Yes, the Boss NS-2 has a DC Out jack that can be used to power other pedals. Make sure the total current draw of the connected pedals does not exceed the power supply's capacity, typically 200 mA for the Boss PSA adapter.

What should I do if my Boss NS-2 is not turning on?

Check the power source, whether it is a battery or a power adapter. Ensure the battery is not depleted or the adapter is properly connected and functioning. Also, check the input cable, as the pedal requires a plug in the input jack to power on.

How can I use the Boss NS-2 with a high-gain amp setup?

For a high-gain amp setup, connect the guitar to the NS-2's input, then use the 'Send' jack to connect to the amp's input. Effects in the amp's loop should connect from the NS-2's 'Return' to the amp's return. This setup helps manage preamp noise and effects loop noise simultaneously.

What is the 'Reduction' mode on the Boss NS-2?

The 'Reduction' mode on the Boss NS-2 allows you to manually engage the noise reduction circuitry. In this mode, the pedal continuously reduces noise, which is useful for silent tuning or checking connections without noise interference.

How do I maintain my Boss NS-2 pedal for optimal performance?

To maintain your Boss NS-2, regularly check and clean the jacks and footswitch to prevent dust buildup. Replace the battery as needed, and ensure the pedal is stored in a cool, dry place when not in use to prolong its lifespan.
