The power supply is outboard, but not dual mono, like the LS 300. In keeping with the ‘9’ series of products, we took the best elements of our Reference design and built them into a more compact, simple, and elegant enclosure. This allows us to keep 95% of the sonics of the Reference product and reduce the price by nearly $5,000. I am quite pleased with the result.\n\u003cbr\u003e\u003cbr\u003e\n\u003cb\u003eFEATURES\u003c\/b\u003e\u003cbr\u003e\n(2) XLR Fully Balanced Inputs.\u003cbr\u003e\n(3) RCA Inputs.\u003cbr\u003e\n(1) RCA HT\/BP (Home Theater Bypass Input).\u003cbr\u003e\n(2) XLR Fully Balanced Outputs.\u003cbr\u003e\n(2) RCA Outputs.\u003cbr\u003e\nDual Remote 12V Trigger Outputs.\u003cbr\u003e\nRemote Control: Volume, mute and trigger outputs.\u003cbr\u003e\nTube Output: 6922\/6DJ8\/7308\/E88CC\u003cbr\u003e\nTube Rectified: 5AR4\/GZ34 and Equivalents.\u003cbr\u003e\nPure Class A.\u003cbr\u003e\nExternal Power Supply.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\n  \u003cdiv style=\"max-width:1200px;margin:0 auto;font-family:Arial,sans-serif;text-align:center;\"\u003e\n  \u003c!-- Image --\u003e\n  \u003cdiv style=\"background:#ffffff;padding:40px 20px;\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0529\/7117\/6085\/files\/3-ls-99-side-stock-tube-scaled.webp?v=1775147360\" alt=\"Product Image\" style=\"max-width:100%;height:auto;\"\u003e\n  \u003c\/div\u003e\n\n\u003chr style=\"border:none;height:2px;width:100%;margin:50px 0;background:linear-gradient(to right, transparent, #000000, transparent);\"\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv style=\"max-width:1200px;margin:0 auto;font-family:Arial,sans-serif;color:#333;\"\u003e\n\n  \u003c!-- Title --\u003e\n  \u003ch2 style=\"font-size:56px;margin:40px 0 30px 0;font-weight:800;\"\u003eTechnical Spec\u003c\/h2\u003e\n\n  \u003c!-- Grid --\u003e\n  \u003cdiv style=\"display:flex;flex-wrap:wrap;gap:40px;\"\u003e\n\n    \u003c!-- Column 1 --\u003e\n    \u003cdiv style=\"flex:1;min-width:280px;line-height:1.6;\"\u003e\n      \u003cstrong\u003eGain: \u003c\/strong\u003e\u003cbr\u003e\n11dB.\n\n      \u003cbr\u003e\n      \u003cstrong\u003eFrequency Response: \u003c\/strong\u003e\u003cbr\u003e\n      20Hz – 150Khz flat.\n\n      \u003cbr\u003e\n      \u003cstrong\u003eInput Impedance: \u003c\/strong\u003e\u003cbr\u003e\n      30K.\n\n      \u003cbr\u003e\n      \u003cstrong\u003eOutput Impedance: \u003c\/strong\u003e\u003cbr\u003e\n      100 ohm.\n\n    \u003c\/div\u003e\n\n    \u003c!-- Column 2 --\u003e\n    \u003cdiv style=\"flex:1;min-width:280px;line-height:1.6;\"\u003e\n      \u003cstrong\u003eNoise Floor: \u003c\/strong\u003e\u003cbr\u003e\n-110dB (unweighted).\u003cbr\u003e\n      \u003cstrong\u003eDimensions: \u003c\/strong\u003e\u003cbr\u003e\nPreamp = 10.5”W x 4.5”H x 12”D.
