Over MHLink, the preamps can sit up to 100 meters from the control position with no added latency and none of the signal degradation typical of long low-level mic cable runs.

Eight ULN-R preamps in one unit removes the risk of tonal mismatch between different preamp models pulled together from outboard gear. Every channel shares the same -22 dB to +91.5 dB gain range in 0.5 dB steps, the same 115 dB flat dynamic range, and the same -110 dB crosstalk figure at 1 kHz, giving predictable, repeatable results regardless of which of the eight channels is in use.\n\n\u003ch3\u003eOne Unit Instead of Multiple Outboard Devices\u003c\/h3\u003e\nRather than patching the LIO-8 into external preamps through additional line inputs and cabling, the full 1-8 kit closes the entire mic signal path inside one unit — fewer failure points, less cabling in the rack, simpler gain staging when setting up a session. THD across the D\/A\/A\/D loop at -12 dBFS measures 0.0007%, so even with all eight channels running simultaneously the path stays transparent, without the distortion buildup typical of mixing gear from different vendors.\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEight ULN-R preamps identical to those used in the ULN-8\u003c\/li\u003e\n\u003cli\u003eIncludes an 8-channel DB-25 input board\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\u003eConsistent tonal character across all eight channels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel number: 003-11013\/16X2\u003c\/li\u003e\n\u003cli\u003eChannel count: 8 (1-8)\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":54336243761489,"sku":"46186","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/MetricHaloLIO-88Channel_1-8_ULN-RPreampKit.jpg?v=1784569302"},{"product_id":"metric-halo-lio-8-4-channel-1-4-uln-r-preamp-kit","title":"Metric Halo LIO-8 4 Channel (1-4) ULN-R Preamp Kit","description":"\u003cdiv lang=\"en\"\u003e\n\u003cstrong\u003eMetric Halo LIO-8 4 Channel (1-4) ULN-R Preamp Kit\u003c\/strong\u003e — an expansion module adding four ULN-R preamps to channels 1-4 of a LIO-8, bundled with an 8-channel DB-25 input connector board.\n\nUnlike the 5-8 kit, this one includes the 8-channel DB-25 input board, making it the natural starting point for a LIO-8 owner who has so far only used line-level inputs and wants ULN-8-grade mic inputs for the first time.

This kit removes that limitation by bringing in the same ULN-R preamp design used in the ULN-8 — gain range from -22 dB to +91.5 dB, 0.5 dB steps, ±0.05 dB precision. A 115 dB flat dynamic range and a 117.9 dB A-weighted noise floor mean tracking vocals or acoustic guitar directly into the LIO-8 no longer requires an outboard preamp or a compromise in signal path.\n\n\u003ch3\u003eA Foundation for a Full 8-Channel System\u003c\/h3\u003e\nInstalling the DB-25 board together with the first four channels sets up the unit for a full 8-mic-input expansion later with no extra wiring — just add the 5-8 kit down the line.

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.

Mute-A-Rang solves this at the hardware level — relays break the signal path in the analog domain, delivering silent, click-free muting independent of DSP state or host software behavior. That matters when running loud monitor systems in a control room, where every switching transient is audible and fatiguing over a long session.\n\n\u003ch3\u003eUpgrading Without Replacing the Whole Unit\u003c\/h3\u003e\nRather than a costly interface replacement or a full mkIV conversion, this kit lets owners retrofit relay mute functionality onto an existing ULN-8 or LIO-8 3d while keeping the current digital platform and any installed expansion cards intact.
