Not a single component or design feature was compromised during the conversion to a smaller package. As a result, the circuit boards are packed with all kinds of delightful components, including a robust Cinemag input transformer! The power supply is the backbone of any preamplifier design and can have a huge impact on the overall sound and performance of the preamplifier. The +24V rail needed to power the BLACK LION AUDIO B173 500 is carefully converted from the +\/- 16V rails of a 500 series rack using a custom DC-DC converter circuit specifically designed to avoid any unwanted noise or modulation from the signal path. Complete isolation is then achieved through the use of inductors, ferrite beads, decoupling capacitors, power regulation, and a custom enclosure surrounding the entire circuit. The BLACK LION AUDIO B173 500's discrete \"Class A\" circuitry combined with high-end components offers a new approach to a classic sound that will not disappoint!\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003e500 series format (requires 500 series rack)\u003c\/li\u003e\n\n\u003cli\u003eCinemag Input Transformer\u003c\/li\u003e\n\n\u003cli\u003eEdcor Output Transformer\u003c\/li\u003e\n\n\u003cli\u003e80dB Gain\u003c\/li\u003e\n\n\u003cli\u003eHi-Z Input (passive, unbalanced)\u003c\/li\u003e\n\n\u003cli\u003ePhantom Power\u003c\/li\u003e\n\n\u003cli\u003ePhase Switch\u003c\/li\u003e\n\n\u003cli\u003eOutput Attenuator\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch4\u003eMic Section\u003c\/h4\u003e\n\u003cul\u003e\n\n\u003cli\u003eMaximum microphone input level: +1 dBu\u003c\/li\u003e\n\n\u003cli\u003eInput Impedance: 200Ω\u003c\/li\u003e\n\n\u003cli\u003eGain: +12 dB to +80 dB\u003c\/li\u003e\n\n\u003cli\u003eEquivalent Input Noise (noise floor): -103 dB\u003c\/li\u003e\n\n\u003cli\u003eTHD + N (@ +4dBu output):\u003c\/li\u003e\n\n\u003cli\u003e.072% at +8 dBu Gain\u003c\/li\u003e\n\n\u003cli\u003e.074% @ +29 dBu Gain\u003c\/li\u003e\n\n\u003cli\u003e.082% @ +44 dBu Gain\u003c\/li\u003e\n\n\u003cli\u003e.152% at +60 dBu Gain\u003c\/li\u003e\n\n\u003cli\u003e.709% @ +76 dBu Gain\u003c\/li\u003e\n\n\u003cli\u003eBandwidth (1kHz, 150Ω source, unweighted): 10Hz to 30kHz\u003c\/li\u003e\n\n\u003cli\u003eHi-Z Section\u003c\/li\u003e\n\n\u003cli\u003eTHD + N (@ +4dBu output):\u003c\/li\u003e\n\n\u003cli\u003e.0045% @ +10 dBu\u003c\/li\u003e\n\n\u003cli\u003e.0076% @ +15 dBu\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch4\u003eOutput Section\u003c\/h4\u003e\n\u003cul\u003e\n\n\u003cli\u003eMaximum output level: +29 dBu\u003c\/li\u003e\n\n\u003cli\u003eOutput Impedance: 600Ω\u003c\/li\u003e\n\n\u003cli\u003ePower Supply\u003c\/li\u003e\n\n\u003cli\u003e+24 V supplied by very low noise,\u003c\/li\u003e\n\n\u003cli\u003ecustom power supply (500 series rack\u003c\/li\u003e\n\n\u003cli\u003erequired)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch4\u003eDimensions\u003c\/h4\u003e\n\u003cul\u003e\n\n\u003cli\u003eMeasurements: 38.1 mm x 165.1 mm x 135.35 mm\u003c\/li\u003e\n\n\u003cli\u003eWeight: 0.54 Kg\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"BLACK LION","offers":[{"title":"Default Title","offer_id":53993909190989,"sku":"B173500","price":369.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/94629-large_default.jpg?v=1779947570","url":"https:\/\/musicdelivery.net\/en\/products\/black-lion-audio-b173-500-preamplificatore-microfonico-serie-500","provider":"Music Delivery","version":"1.0","type":"link"}
