{"product_id":"black-lion-b173-quad-401534","title":"B173 Quad","description":"\u003ch3\u003eA Classic Preamplification Legend, Now in a Multi-Channel Studio Format\u003c\/h3\u003e\u003cp\u003eThe B173 Quad follows the tradition of \"1073-style\" preamps: an approach that favors \u003cstrong\u003ehigh headroom preamplification\u003c\/strong\u003e, \u003cstrong\u003emusical harmonic saturation\u003c\/strong\u003e when pushing the gain, and a sense of \u003cstrong\u003etexture\u003c\/strong\u003e often sought after during tracking. While this type of preamp is frequently used channel by channel, this \u003cstrong\u003e4-channel\u003c\/strong\u003e version allows you to achieve the same sonic aesthetic across multiple sources simultaneously, all within a practical \u003cstrong\u003e19-inch rack\u003c\/strong\u003e format ideal for studio setups.\u003c\/p\u003e\u003ch3\u003eWho It's For and What It's For: Recording, Light Reamping, and Conversion Front-End\u003c\/h3\u003e\u003cp\u003eThis preamp is designed for sound engineers, demanding home-studiers, and project studios seeking a characterful \u003cstrong\u003efront-end\u003c\/strong\u003e to drive a converter or audio interface. With its \u003cstrong\u003e4 channels\u003c\/strong\u003e, it is particularly relevant for drums (kick\/snare\/overheads), ensembles (stereo piano + vocals, quartet, percussion), or to unify the color on multi-mic recordings. The \u003cstrong\u003eDI inputs\u003c\/strong\u003e on channels 1 and 2 also facilitate direct recordings (bass, guitar, keyboards) with a livelier grain than a standard instrument input.\u003c\/p\u003e\u003ch3\u003e\"Class A\" Sound with Transformers: Dynamics, Thickness, and Control\u003c\/h3\u003e\u003ch4\u003eHigh Gain and Solid Headroom\u003c\/h4\u003e\u003cp\u003eWith a \u003cstrong\u003emicrophone gain from 12 to 70 dB\u003c\/strong\u003e adjustable \u003cstrong\u003ein steps\u003c\/strong\u003e, the B173 Quad suits both dynamic microphones requiring lots of gain and modern condensers. Its \u003cstrong\u003emaximum output level of +28 dBu\u003c\/strong\u003e helps preserve dynamics and handle transients, while the \u003cstrong\u003e48 V\u003c\/strong\u003e phantom power switching per channel simplifies session use (no need to activate phantom power across the entire rack).\u003c\/p\u003e\u003ch4\u003eCinemag Transformers: Character and Coherence\u003c\/h4\u003e\u003cp\u003eThe \u003cstrong\u003eCinemag transformers\u003c\/strong\u003e on input and output contribute to the sound: fuller lows, present mids, and a pleasant harmonic compression when approaching limits. This allows you to sculpt the recording right at tracking by adjusting the \u003cstrong\u003einput gain \/ output level\u003c\/strong\u003e relationship to achieve either a clean and spacious capture or a denser, more textured signal.\u003c\/p\u003e\u003ch4\u003eDI on Channels 1 and 2: Convenient for Electric Sources\u003c\/h4\u003e\u003cp\u003eChannels 1 and 2 feature an \u003cstrong\u003easymmetrical 6.3 mm jack instrument input\u003c\/strong\u003e, useful for quickly recording a bass line, guitar, or synth. The high DI input impedance ensures good compatibility with passive pickups and better attack preservation, while benefiting from the same characterful analog path.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:2;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eNumber of channels\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e4\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eRack unit\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e2\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:1;--wb-r:9;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eChannels 1 and 2\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eadditional DI input\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eDI input impedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e1.1 MOhm (unbalanced)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:2;--wb-r:10;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eMax input level\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003emic input +1 dBu \/ DI input +18 dBu\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eMax output level\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e+28 dBu\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:3;--wb-r:11;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e10 -
