Follows description from Equipboard:

The Boss NS-2 Noise Suppressor is a compact analog guitar and bass effects pedal that eliminates unwanted background noise and hum without altering the instrument's fundamental tone. It works by detecting the clean signal from your instrument and separating it from any added noise, effectively silencing the signal during quiet pauses. 

How it works

The NS-2 uses a fast-acting, high-quality VCA (Voltage Controlled Amplifier) and envelope-detecting circuits to distinguish between the guitar's sound and background noise. When the signal drops below a certain threshold, the pedal acts as a noise gate, muting the signal. This analog circuitry is designed to create a smoother, more organic cutoff than conventional noise gates, preserving the instrument's natural playing feel and note decay. 

Features and controls

The NS-2's features provide versatility for various setups. 

• Unique Send/Return Loop: This is a key feature that distinguishes the NS-2. Placing your high-gain, noise-producing pedals (such as distortion and overdrive) within the NS-2's loop allows the pedal to detect your clean guitar signal separately from the noise generated by the effects. This ensures optimal noise reduction while preserving your tone.
• Threshold Knob: This control sets the level at which the noise suppression begins. You can adjust it based on your instrument's signal and the amount of noise in your rig.
• Decay Knob: This knob adjusts how long it takes for the sound to fade to silence after the input drops below the threshold. A longer decay setting creates a more natural sound, while a faster setting creates the tight, choppy gating effect favored by many metal players.
• Mode Switch: This switch offers two operating modes:
• • Reduction Mode: When you engage the pedal, it suppresses the noise. When you bypass the pedal, the signal passes through normally.
  • Mute Mode: Engaging the pedal completely mutes your signal, which is useful for tuning or switching instruments silently.
• DC Output Jack: When powered with a PSA-series adapter (sold separately), the NS-2 can distribute power to other pedals on your pedalboard, helping to reduce cable clutter.
