The most affordable of SMSL’s power amps, the A300 is a streamlined machine that shines where it matters most. It uses high-quality audiophile components and boasts must-have features like Bluetooth 5.0, a subwoofer pre-out, and dual or single channel modes. \nDual and BTL (single-channel)\nRun the A300 in dual-channel or BTL (single-channel mode). In dual-channel mode, it runs two independent speakers at 165Wx2 (4Ω) / 85Wx2 (8Ω). In BTL (single-channel mode), it runs one large speaker at 330Wx1 (4-8Ω). \nAdd a subwoofer \nThanks to a built-in high-pass filter circuit, the A300 can filter out the subwoofer frequencies in your main speakers and send them to a subwoofer to form a 2.1 system. Just connect a subwoofer to the subwoofer signal pre-output, and you’re ready to roll. \nBluetooth 5.0\nStream music directly to the A300 from your phone, computer, tablet, or laptop with Bluetooth 5.0. With longer transmission distance and better sound quality, Bluetooth 5.0 lets you control the music from up to 800 feet away. \nProduct highlights\n\nNew German Infineon digital high-power amp chip\nJapanese NJRC volume control chip\nSMSL SDB patented sound effects\nFeatures 2.1 system support\nBluetooth 5.0\nDedicated switching power supply\nNewly designed remote control\n\nSpecs\n\nInputs: RCA, Bluetooth, USB\nTHD+N: 0.004%\nSNR: 103dB\nChannel separation: 85dB\nCutoff frequency (in high pass mode): 50Hz\nInput sensitivity/ input impedance: 280mV/22kΩ\nOutput power\n\nStereo: 165Wx2 (4Ω) / 85Wx2 (8Ω)\nBTL: 330Wx1 (4-8Ω)\n\nPower consumption: 40W (normal volume)\nSize: 8.28” x 1.6” x 7.79”  (210.5 x 41 x 198mm)\nWeight 2.86lbs (1.3kg)\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132352192748.jpg?v=1654135272","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351045868.jpg?v=1654135811","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351340780.jpg?v=1654135469","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351504620.jpg?v=1654135471","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351373548.jpg?v=1654135467","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351537388.jpg?v=1654135638","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351471852.jpg?v=1654135641","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351439084.jpg?v=1654135274","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351209708.jpg?v=1654135815","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351144172.jpg?v=1654135819","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351406316.jpg?v=1654135277","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351242476.jpg?v=1654135632","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351111404.jpg?v=1654135635","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351308012.jpg?v=1654135450","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351275244.jpg?v=1654135454","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351078636.jpg?v=1654135457","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-smsl-headphone-amp-smsl-a300-power-amplifier-37132351176940.jpg?v=1654135465"],"price":195.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:00.447Z"},"share_url":"https://firestarter.network/l/lst_RLRofJvO","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
