Installation applies only to units that already have the input board wired — the module itself mounts into the existing connector slot without additional signal cabling.\n\n\u003ch3\u003eLow-Noise Signal Path at High Gain\u003c\/h3\u003e\nCapturing quiet sources — ribbon mics, subtle vocal takes, distant-miked acoustic instruments — demands 60-90 dB of gain without lifting the noise floor of the signal chain. The ULN-R covers a gain range from -22 dB to +91.5 dB in 0.5 dB steps at ±0.05 dB precision, giving fine control instead of coarse jumps that force a re-take. Dynamic range sits at 115 dB flat (0-22.05 kHz) with a noise floor of 115 dB flat \/ 117.9 dB A-weighted, so pushing gain high on a quiet source doesn't add audible hiss to vocal or string tracks in the mix.\n\n\u003ch3\u003eScalable System Expansion Without a New Interface\u003c\/h3\u003e\nInstead of purchasing a separate 8-channel interface, a LIO-8 owner adds the 5-8 module to an existing input board and reaches a full 8 channels of ULN-8-grade mic preamps. THD across the D\/A\/A\/D loop at -12 dBFS measures 0.0007%, and crosstalk between channels at 1 kHz stays at -110 dB — figures that matter when tracking a full band simultaneously, where every added channel needs to hold the same transparency as the first four.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFour ULN-R preamps identical to those used in the ULN-8\u003c\/li\u003e\n\u003cli\u003eHandles dynamic, condenser, and ribbon mics plus line and instrument-level signals\u003c\/li\u003e\n\u003cli\u003e+48V phantom power, independently switchable per channel\u003c\/li\u003e\n\u003cli\u003eHigh rejection of RFI and common-mode noise\u003c\/li\u003e\n\u003cli\u003eChannels 5-8 require a pre-installed 8-channel DB-25 input board\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel number: 003-11013\u003c\/li\u003e\n\u003cli\u003eInput impedance: 3.3 kΩ\u003c\/li\u003e\n\u003cli\u003eDynamic range (flat, 0-22.05 kHz): 115 dB\u003c\/li\u003e\n\u003cli\u003eDynamic range (A-weighted): 118 dB\u003c\/li\u003e\n\u003cli\u003eGain range: -22 dB to +91.5 dB, 0.5 dB steps\u003c\/li\u003e\n\u003cli\u003eTHD D\/A\/A\/D loop @ -12 dBFS: 0.0007%\u003c\/li\u003e\n\u003cli\u003eCrosstalk @ 1 kHz: -110 dB\u003c\/li\u003e\n\u003cli\u003ePhantom power: +48V, switchable per channel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Metric Halo","offers":[{"title":"Default Title","offer_id":54336243892561,"sku":"46185","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/MetricHaloLIO-84Channel_5-8_ULN-RPreampKit.jpg?v=1784569282","url":"https:\/\/wrdtunes.com\/fr\/products\/metric-halo-lio-8-4-channel-5-8-uln-r-preamp-kit","provider":"Wired Tunes","version":"1.0","type":"link"}
