{"product_id":"atlasied-tsd-pa122g","title":"AtlasIED TSD-PA122G 2-Channel Low Ohm Power Amplifier","description":"\u003cp\u003eThe AtlasIED TSD-PA122G is a two-channel low-ohm power amplifier engineered for fixed-install applications where reliable, straightforward amplification is the priority. AV integrators and systems designers working on small to mid-size commercial spaces — classrooms, boardrooms, conference rooms, and projection system installs — will find its 12W-per-channel output at 4Ω sufficient to power multiple passive loudspeakers without transformer-based distribution complexity.\u003c\/p\u003e\u003cp\u003eUnlike 70V distribution amplifiers, the TSD-PA122G operates in the low-ohm domain, making it a clean, cost-effective solution when speaker runs are short and load management is handled at the zone level. Bridged mono operation at 24W into 8Ω extends its utility to single-zone installs requiring more headroom. The amplifier accepts both balanced Phoenix-style and unbalanced RCA inputs simultaneously, accommodating a wide range of source equipment found in installed AV racks.\u003c\/p\u003e\u003cp\u003eDesigned as part of the AtlasIED TSD ecosystem, this amplifier draws external DC power via a separately purchased TSD-series power supply, allowing multiple TSD modules to share a single supply when current budgets allow. This modular approach keeps rack footprint minimal while supporting scalable multi-room builds. The removable connectors and knobs simplify service and future system modifications without rewiring.\u003c\/p\u003e","brand":"Atlas Sound, L.P. - Mitek","offers":[{"title":"Default Title","offer_id":52445850960056,"sku":"20016","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/20016_ATLAS-TSD-PA122G_ALT03sqr.jpg?v=1783457892","url":"https:\/\/soundpro.com\/products\/atlasied-tsd-pa122g","provider":"SoundPro","version":"1.0","type":"link"}
