Its dual mode design lets the amplifier work as a stereo amplifier for a two-channel setup or as a mono amplifier when paired into a scalable left and right configuration.\u003c\/p\u003e\u003ch3\u003eBalanced Input Flexibility\u003c\/h3\u003e\u003cp\u003eZA3 supports RCA, XLR, and 1\/4 inch TRS input options, giving listeners multiple ways to connect DACs, preamps, streamers, and other line-level audio sources. The balanced input path is useful for systems where lower interference and cleaner signal routing matter, especially on desks, shelves, and compact component racks.\u003c\/p\u003e\u003ch3\u003ePower for Stereo or Mono Systems\u003c\/h3\u003e\u003cp\u003eWith a Texas Instruments TPA3255 Class D amplifier chip, the ZA3 supports 2 to 8Ω speakers and rated output up to 155W x2 at 4Ω with a 48V\/5A power supply in stereo mode. In mono mode, it delivers rated output up to 235W x1 at 4Ω, letting users pair two ZA3 amplifiers for a dedicated left and right speaker setup.\u003c\/p\u003e\u003ch3\u003eSubwoofer Output and System Control\u003c\/h3\u003e\u003cp\u003eAn active subwoofer output makes it easier to build a 2.1 channel listening system with passive speakers and a powered subwoofer. The 12V trigger input allows synchronized power control with compatible devices, reducing the need to turn each component on or off separately.\u003c\/p\u003e\u003cp\u003eThe aluminum alloy chassis, side ventilation, dust covers, and whole-body heatsink support stable operation in compact spaces. Swappable DIP8 dual op amp support also gives advanced users room to tune the amplifier to their preferred sound profile.\u003c\/p\u003e","brand":"Cleanbox Technology","offers":[{"title":"Default Title","offer_id":47322192642204,"sku":"ZA3-FOSI","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/2147\/3180\/files\/o5xz5uyxjzpr_d4d43f2e-01dc-4c87-b3f6-6435cd0d5335.jpg?v=1786010209","url":"https:\/\/focuscameras.shop\/products\/fosi-audio-za3-balanced-stereo-amplifier-lrfgzj","provider":"Cypress \u0026 Main","version":"1.0","type":"link"}
