Metric Halo Channel 1-4 Mic Pre Upgrade Kit

We based the LIO-8 on this platform, to provide the same sonic excellence for users that don’t need 8 channels of mic pres; editing, mastering and mix suites as well as those that use analog consoles or their own mic pres.So why add mic pres back?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) we give you the option to upgrade. We call this “Future Proof” and it’s part of the design philosophy at Metric Halo.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.SpecsRailsPreamp Rails ±15.8 VoltsPhantom Power 48 ± 0.1 VoltsMax Phantom Current Per Mic 10 maMic Pre Input + ADCInput Impedance 3.3 kΩDynamic Range (-60 dB, flat 0-22.05 kHz, typ) 115 dBDynamic Range (-60 dB, A-weighted, typ) 118 dBNoise Floor (flat 0-22.05 kHz, typ) 115 dBNoise Floor (A-weighted, typ) 117.9 dBGain Range -22 dB to +91.5 dBGain Precision ±0.05 dBGain Step 0.5 dBTHD D/A/A/D loop @ -12 dBFS 0.0007 %THD D/A/A/D loop @ -12 dBFS +12 dB Gain 0.0015 %THD D/A/A/D loop @ -0 dBFS 0.0023 %Crosstalk @ 1kHz -110dBIMD 1k component (19 kHz/20kHz @ +8dBu) -104 dBuEIN @ 60 dB Gain (150Ω Source Impedance) -130.50 dBuEIN @ 60 dB Gain (0Ω Source Impedance) -133.25 dBuAnalog Send Calibration (ADC = 0 dBFS) +21.5 dBuPhantom Power (Switchable Per Channel) +48 VoltsMic Pre + ADC Frequency Response+0/-0.1dB @ fs = 44100 Hz 8.9 Hz – 20.5 kHz+0/-1.0dB @ fs = 44100 Hz 2.9 Hz – 21.0 kHz+0/-0.1dB @ fs = 96000 Hz 8.9 Hz – 43.9 kHz+0/-1.0dB @ fs = 96000 Hz 2.9 Hz – 45.4 kHz+0/-0.1dB @ fs = 192000 Hz 8.9 Hz – 42.1 kHz+0/-1.0dB @ fs = 192000 Hz 2.9 Hz – 64.7 kHz5° low-end in-channel phase deviation point 20.0 HzInterchannel phase 0 Hz – 20 kHz< ±0.05°Crosstalk from SMPTE Input< -142 dBHow to get itInstalling the ULN-R option is simple- open the top casing, remove the DB25 block-off plate from the rear panel, install the mic pre(s) and riser card and replace the top casing. If you are not comfortable working with static-sensitive electronics, you can have us do the upgrade for you; when you order your upgrade, we will issue an RMA for you to send your unit into the Custom Shop and our technicians will install the option for you. Turn around time is typically 1 week from date of receipt of the unit.
