{"product_id":"rockboard-ha-1-402441","title":"HA 1","description":"\u003ch3\u003eRockBoard HA 1: a monitoring headphone amplifier designed to focus on the essentials\u003c\/h3\u003e\u003cp\u003eThe RockBoard HA 1 embodies the idea of accessible and hassle-free personal monitoring: a compact unit, immediate connectivity, and straightforward controls. It serves as a direct link between an audio source (mixer, interface, headphone\/line output depending on your setup) and your in-ear monitors, allowing you to take control of your volume without monopolizing front-of-house settings. When every minute counts before a gig, it provides a quick solution to secure a clear and consistent monitor mix.\u003c\/p\u003e\u003ch3\u003eFor which musicians and daily uses?\u003c\/h3\u003e\u003cp\u003eThe HA 1 is aimed at singers, drummers, keyboardists, guitarists, and bassists who want a stable headphone monitor mix without relying on a wedge monitor and without suffering from level fluctuations on stage. In small clubs, it helps improve clarity while limiting feedback risks associated with traditional monitors. During rehearsals, everyone can maintain consistent listening comfort, which enhances tuning, rhythmic cohesion, and the group's dynamics. At home, it becomes a practical tool for cleanly working on rehearsal mixes or signals sent from an interface, with volume control always at hand.\u003c\/p\u003e\u003ch3\u003eKey features: reliable monitoring, quick to set up\u003c\/h3\u003e\u003ch4\u003eA combo input to adapt to your source\u003c\/h4\u003e\u003cp\u003eThe combined XLR \/ 6.35mm Jack input facilitates integrating the HA 1 into various setups. You can simply insert it between a mixer output and your in-ear monitors, or use it as a personal monitoring solution whenever a compatible signal is available. This versatility reduces the need for adapters and helps maintain efficiency during stage changes or quick setups.\u003c\/p\u003e\u003ch4\u003eStereo or mono: the right mode without complication\u003c\/h4\u003e\u003cp\u003eThe stereo\/mono switch is a major asset when conditions are less than ideal. If you receive a stereo feed, you retain a more natural image, useful for positioning vocals, keyboards, and ambience. If the feed is mono (or if you want a centered and homogeneous listening experience), switching to mono avoids surprises and ensures coherent sound in both earpieces. Simply plug in, choose \"stereo\" or \"mono,\" then adjust your level: the workflow is immediate.\u003c\/p\u003e\u003ch4\u003eVolume control on\/off: maximum responsiveness on stage\u003c\/h4\u003e\u003cp\u003eThe volume potentiometer integrates the on\/off function, simplifying use between songs, during soundcheck, or when changing instruments. This direct approach is especially suitable for musicians who want a single, clear, and fast control without menus or secondary settings. Result: less hesitation, more focus on playing.\u003c\/p\u003e\u003ch4\u003eBattery life and indicator: the right reflex before the set\u003c\/h4\u003e\u003cp\u003ePowered by 2 AAA batteries, the HA 1 offers up to 12 hours of autonomy, a reassuring format for long sessions. The battery status LED helps anticipate power levels: you check at a glance and avoid discovering a power drop at the wrong moment. The external battery compartment with clip closure allows quick replacement, practical when stage time is limited.\u003c\/p\u003e\u003ch4\u003eRobust design and mobility\u003c\/h4\u003e\u003cp\u003eIts aluminum chassis and sturdy belt clip are designed for intensive use: transport, stage, rehearsals, frequent travel. Worn on the belt or attached nearby, it remains discreet and limits cable strain. The compact format also helps keep a clean setup, particularly appreciated in tight environments (crowded stages, pits, small rehearsal rooms).\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eBlack\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eheadphone amplifier for in-ear monitoring\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eEnclosure\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003ealuminum, compact and lightweight format with belt clip\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eControls\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003evolume on\/off, stereo\/mono source selector\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eIndicator\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003ebattery status LED\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eInput\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003ecombo XLR \/ 6.35mm Jack (stereo)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eHeadphone output\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e3.5mm stereo Jack\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eMaximum output power\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e2 x 110 mW at 16 Ohms\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eOutput impedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eless than 0.1 Ohm\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003ePower supply\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e2 AAA batteries (not included)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eBattery life\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eup to 12 hours\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eBattery access\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eexternal compartment with clip closure\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e141 x 30 x 36 mm\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e111 g\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Rockboard","offers":[{"title":"Default Title","offer_id":54360899682579,"sku":"402441","price":35.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/76ce1603fc2f8bcf66d7051e9c651060ca195bce_ROCKBOARD_HA1_6e13d4e4-b5ea-491d-b916-f5c9e94ea861.jpg?v=1787399115","url":"https:\/\/woodbrass.shop\/products\/rockboard-ha-1-402441","provider":"Woodbrass.com","version":"1.0","type":"link"}
