  • You may find yourself needing pres after purchasing a LIO-8. Rather than forcing you to buy more gear (or sell your LIO to buy a ULN-8) you have the option to upgrade. This also lets you build a system over time; buy a LIO-8 today to get outstanding conversion and processing. Add four channels of ULN-R mic pres later, and another four after that. You can even add a +DSP license to your LIO-8 to tap into the full capabilities of the 2d card in your LIO-8. Another benefit of having the ULN-R mic pres onboard is that you can take advantage of the LIO's flexible signal routing to use the Mic and Line inputs with the Sends to create pre-A/D convertor insert points.

    What's so great about the ULN-R pres?
    The ULN-R mic pre possesses virtually every characteristic that is coveted in a Mic Preamp: exceptionally low noise at all gains, exceptionally high gain, excellent common mode and RFI rejection, incredibly flat frequency response, and ultra-low distortion. It simply increases the level of what you put into it without having to consider the nature of the source: Dynamic Mics, Phantom Powered Mics, Ribbon Mics, turntables, Instrument or line level signals are all handled with equal ease and quality.
