Mute-A-Rang solves this at the hardware level — relays break the signal path in the analog domain, delivering silent, click-free muting independent of DSP state or host software behavior. That matters when running loud monitor systems in a control room, where every switching transient is audible and fatiguing over a long session.\n\n\u003ch3\u003eUpgrading Without Replacing the Whole Unit\u003c\/h3\u003e\nRather than a costly interface replacement or a full mkIV conversion, this kit lets owners retrofit relay mute functionality onto an existing ULN-8 or LIO-8 3d while keeping the current digital platform and any installed expansion cards intact. This makes sense for studios already invested in the 3d ecosystem that need reliable hardware monitor muting without taking on the full mkIV feature set.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRelay-based muting on monitor output signal paths\u003c\/li\u003e\n\u003cli\u003eInstalls inside the existing 3d unit without a full electronics swap\u003c\/li\u003e\n\u003cli\u003eEliminates clicks and pops typical of software-driven mute\u003c\/li\u003e\n\u003cli\u003eNo mkIV upgrade required to gain this functionality\u003c\/li\u003e\n\u003cli\u003eAlready standard on mkIV units — kit applies only to the 3d platform\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel number: 000-50049\u003c\/li\u003e\n\u003cli\u003eCompatibility: ULN-8 3d, LIO-8 3d, LIO-8\/4p 3d\u003c\/li\u003e\n\u003cli\u003eUpgrade type: internal relay module, unit-mounted\u003c\/li\u003e\n\u003cli\u003eScope of operation: monitor output signal paths\u003c\/li\u003e\n\u003cli\u003emkIV status: built-in as standard, kit not required\u003c\/li\u003e\n\u003cli\u003eInstallation: service-level, requires opening the unit chassis\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Metric Halo","offers":[{"title":"Default Title","offer_id":54336243990865,"sku":"46183","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/MetricHaloMute-A-RangMonitorMuteKit.jpg?v=1784569271","url":"https:\/\/wrdtunes.com\/en-fr\/products\/metric-halo-mute-a-rang-monitor-mute-kit","provider":"Wired Tunes","version":"1.0","type":"link"}
