Turning amplifier gains down can hide some of it, but that also gives away usable output and does not fix the source of the problem. The NGM is for that specific integration issue: standing hiss or background noise coming through the signal path between tracks or during quiet passages.\u003c\/p\u003e\u003cp\u003eThe NGM watches the incoming signal and opens or closes the audio path around a user-set threshold. That lets the system stay quiet when the source is effectively idle, then pass the music normally once the signal rises above the gate point.\u003c\/p\u003e\u003ch3\u003eWhere it makes sense\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM integration where the factory source or amplifier leaves an audible background noise floor\u003c\/li\u003e\n\u003cli\u003eAftermarket systems with a known source-level hiss that remains after proper gain structure and wiring have been verified\u003c\/li\u003e\n\u003cli\u003eRCA-level or supported speaker-level signal paths\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis is not a universal cure for every alternator whine, bad ground or damaged component. Those problems should be repaired at the source. The NGM is useful when the system is electrically correct but the source architecture itself leaves standing noise that needs to be gated.\u003c\/p\u003e\u003ch3\u003eSignal flexibility\u003c\/h3\u003e\u003cp\u003eARC supports both low-level RCA and speaker-level input, with speaker-level input capability up to 20 volts and output capability up to 7 volts. That makes the module useful in both conventional aftermarket signal chains and selected factory-radio integration jobs where a high-level signal has to be managed before it reaches the next component.\u003c\/p\u003e\u003cp\u003eARC also provides selectable filtering behavior so the module can be configured around the actual noise problem instead of treating every installation the same.\u003c\/p\u003e\u003ch3\u003eNGM vs. SRI vs. BXM\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eChoose NGM\u003c\/strong\u003e when the problem is standing background noise or hiss in an otherwise usable signal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoose SRI\u003c\/strong\u003e when the factory system divides the music across multiple band-limited speaker outputs and those signals need to be summed into a usable full-range feed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoose BXM\u003c\/strong\u003e when the signal is clean but the system needs perceived low-frequency extension without simply piling on boost below the speaker's useful range.\u003c\/p\u003e\u003ch3\u003eManufacturer specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLow-level RCA and speaker-level input capability\u003c\/li\u003e\n\u003cli\u003eSpeaker-level input capability up to 20 V\u003c\/li\u003e\n\u003cli\u003eOutput capability up to 7 V\u003c\/li\u003e\n\u003cli\u003eUser-adjustable noise-gate operation\u003c\/li\u003e\n\u003cli\u003eSelectable filter behavior\u003c\/li\u003e\n\u003cli\u003eCompact installation format\u003c\/li\u003e\n\u003cli\u003ePower, ground and remote-turn-on connection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARC Audio","offers":[{"title":"NGM","offer_id":51792891085033,"sku":"NGM","price":124.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0311\/8134\/0811\/files\/arc-audio-ngm-noise-gate-module.jpg?v=1788432416","url":"https:\/\/smscaraudio.com\/products\/arc-audio-ngm-noise-gate-module-rca-speaker-level-oem-noise-control","provider":"SMS Car Audio","version":"1.0","type":"link"}
