{"product_id":"biamp-920-01949-00001","title":"Biamp Voltera A 300.4 Four-Channel 300W Amplifier","description":"\u003cp\u003eThe Voltera A 300.4 addresses the need for adaptable amplification in commercial environments where loudspeaker types, mounting constraints, and acoustic sensitivity vary. Its four Class D channels support mixed-load systems with independent per-channel selection of 100 V, 70 V, 8-ohm, or 4-ohm operation, eliminating the need for separate amplifiers when distributed and low-impedance speakers coexist in the same installation.\u003c\/p\u003e\u003cp\u003ePower sharing mode allows any channel to deliver up to 150 watts when additional output is required, providing twice the symmetric allocation without reconfiguring the system. Manual per-channel controls including high-pass filtering, gain trim with up to 3 dB boost, and fixed 4 dBu input sensitivity ensure repeatable commissioning and predictable behavior across diverse source equipment and loudspeaker models.\u003c\/p\u003e\u003cp\u003eThe half-rack chassis ships with mounting solutions for standard 19-inch racks and remote placement behind displays, under tables, above ceilings, or within furniture. Thermally controlled fan operation supports whisper mode for noise-sensitive applications such as conference rooms and private offices, while TAA compliance, CE marking, UL listing, and 5-year warranty coverage meet institutional procurement and reliability requirements for long-term commercial deployments.\u003c\/p\u003e","brand":"Biamp Systems","offers":[{"title":"Default Title","offer_id":52451771383992,"sku":"152490","price":1309.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/152490_BIAMP-Voltera-A-300.4_ALT01.jpg?v=1782918336","url":"https:\/\/soundpro.com\/products\/biamp-920-01949-00001","provider":"SoundPro","version":"1.0","type":"link"}
