Metric Halo LIO-8 8 Channel (1-8) ULN-R Preamp Kit — a complete kit adding eight ULN-R preamps across channels 1-8, bundled with an 8-channel DB-25 input board, for the LIO-8 interface.
The kit combines into one purchase what would otherwise require two separate modules (1-4 and 5-8) plus an input board — delivering a full 8-channel ULN-8-grade mic input path on a single LIO-8 unit right away. It suits a studio that already knows it needs a full-size mic input chain, without a staged rollout.
Eight Matched Mic Channels for One Session
On band tracking sessions — drum overheads, vocals, guitars — consistency across channels matters as much as the quality of any single path. 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.One Unit Instead of Multiple Outboard Devices
Rather 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.KEY FEATURES
