{"product_id":"black-lion-b12a-quad-401532","title":"B12A Quad","description":"\u003ch3\u003eA \"312A\" Approach: The DNA of a Classic in a 4-Channel Rack\u003c\/h3\u003e\u003cp\u003eDesigned around a \"312A\" preamp architecture, this 4-channel preamplifier follows the tradition of quick, clean, and musical takes, with comfortable gain reserve and wide frequency response. The goal is clear: to offer a coherent analog front-end capable of handling percussive sources like snare drums or toms, while remaining refined enough for vocals or acoustic guitars. The 1U format and external power supply make it a logical choice for a modern studio rack, whether working in a demanding home studio or control room.\u003c\/p\u003e\u003ch3\u003eWho Is This 4-Channel Preamp For and What Are Its Use Cases?\u003c\/h3\u003e\u003cp\u003eThis model is aimed at sound engineers, producers, and musicians who want to \u003cstrong\u003emultiply microphone inputs\u003c\/strong\u003e without sacrificing quality, with straightforward ergonomics and useful controls. The 4 channels facilitate drum recording (overheads, snare, kick, room), capturing small ensembles, or vocal production by layering multiple takes with a consistent tonal character.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eadditional DI inputs on channels 1 and 2\u003c\/strong\u003e meet current needs: recording a bass direct, a guitar for reamping, or synths, while keeping the possibility to use the other two channels for microphones. This hybrid configuration is ideal for quick sessions alternating between mic and line\/instrument inputs without reconfiguring the entire patch.\u003c\/p\u003e\u003ch3\u003eKey Features: Control, Headroom, and Low Noise Serving the Recording\u003c\/h3\u003e\u003ch4\u003e70 dB Gain and Handling Strong Sources\u003c\/h4\u003e\u003cp\u003eWith a \u003cstrong\u003emicrophone gain range from 26 to 70 dB\u003c\/strong\u003e, the preamp covers both sensitive microphones and more demanding models. For high-level sources, each channel has a \u003cstrong\u003e-18 dB attenuator\u003c\/strong\u003e on the mic input, useful to avoid upstream overload and maintain adjustment headroom. The \u003cstrong\u003emaximum output level of +26 dBu\u003c\/strong\u003e also contributes to excellent headroom in an analog chain.\u003c\/p\u003e\u003ch4\u003eBuilt-in DIs for Instruments and Modern Sources\u003c\/h4\u003e\u003cp\u003eChannels 1 and 2 feature a dedicated \u003cstrong\u003eDI input\u003c\/strong\u003e, with \u003cstrong\u003eDI gain from +10 to 53 dB\u003c\/strong\u003e and an \u003cstrong\u003einput impedance of 1.1 MOhm\u003c\/strong\u003e (unbalanced), promoting healthy interaction with guitar and bass pickups. The \u003cstrong\u003emaximum DI input level of +18 dBu\u003c\/strong\u003e allows accommodating active instruments and some line outputs without stress, depending on the level sent.\u003c\/p\u003e\u003ch4\u003eEssential Recording Tools: 48 V, Phase, and Multi-Mic Coherence\u003c\/h4\u003e\u003cp\u003eIn multi-mic recording, details save time: the \u003cstrong\u003eswitchable 48 V phantom power\u003c\/strong\u003e per channel ensures compatibility with condenser microphones, \u003cstrong\u003ephase inversion\u003c\/strong\u003e facilitates alignment between multiple mics (snare top\/bottom, stereo pair, close and room mic), and the -18 dB pad secures the most energetic takes.
