{"type":"firestarter.listing","listing":{"id":"lst_93mVy6cX","product_name":"VMV A1 PRO Gallium Nitride Power Amp","category":"Speaker Amp","description":"\nA new kind of power amp\n\nThe VMV A1 PRO is a compact high-power amplifier that uses gallium nitride (GaN) transistors—an alternative to silicon that switches faster, runs cooler, and wastes less energy. That means less distortion, tighter transients, and a more compact form factor that doesn’t need a giant heatsink to keep its cool. Whether you’re driving full-size stereo speakers or bi-amping in mono mode, the A1 PRO delivers ultra-clean power.\n\nGallium nitride inside\n\nGallium nitride (GaN) is one of the biggest improvements to power amplification in decades. Unlike traditional silicon transistors, GaN devices can switch at much higher frequencies—up to 1MHz in the case of the A1 PRO. That ultra-fast switching drastically reduces \"dead time,\" the micro-moments when both output transistors are briefly off. Less dead time means less distortion, especially in high-frequency content where timing errors tend to smear detail and sap clarity.\n\nMono mode for extra muscle\n\nWant more power? Switch it into mono mode. With a pair of A1 PROs, you can quadruple the power output and take on more demanding speaker loads. Mono mode gives you up to 400W into 4Ω—enough headroom to power floorstanding speakers with ease. \n\nPrecise volume control  \n\nThe PGA2311 is a digitally-controlled analog volume chip from Texas Instruments that offers precise control and ultra-low distortion. If you’ve ever dealt with volume drift, channel imbalance, or noise at low levels, you’ll appreciate what it brings to the table.\n\nSafeguards built in\n\nThe A1 PRO comes with full-protection circuitry against overheating, overcurrent, and more. You probably won’t trigger them, but it’s good peace of mind, especially if you're running a high-efficiency rig in mono mode.\n\nClean power from a dedicated supply\n\nThe power supply is an audio-grade, high-power switching unit built to match the amp’s dynamic demands. It stays quiet under load and uses just 0.5W in standby, so you can leave it in your rack without worr","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011715.jpg?v=1744741359","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011716.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011726.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011725.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011724.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011723.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011722.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011721.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011720.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011719.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011718.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011717.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011728.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011729.jpg?v=1760652015","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-vmv-speaker-amp-vmv-a1-pro-gallium-nitride-power-amp-1156011727.jpg?v=1760652015"],"price":495,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.661Z"},"share_url":"https://firestarter.network/l/lst_93mVy6cX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
