Android (QMix-UC)Android 5.0 (Lollipop) or laterAndroid™ smartphone or tabletNote: The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio signals.Technical SpecificationsMicrophone PreampInput Type XLR Female, balanced, lockingFrequency Response to Direct Output (at unity gain) 20-40 kHz, ±0.5 dBuFrequency Response to Main Output (at unity gain) 20-20 kHz, ±0.5 dBuInput Impedance 1 kΩTHD to Main Output (1 kHz at unity gain) 0.005%, +4 dBu, 20-20 kHz, unity gain, unwtdS/N Ratio to Main Output (Ref = +4 dB, 20 kHz BW, unity gain, A-wtd) 94 dBCommon Mode Rejection Ratio (1 kHz at unity gain) 65 dBGain Control Range (±1 dB) 0 dB to +65 dBMaximum Input Level (unity gain) +22 dBuPhantom Power (±2 VDC) 48 VDC, switchable per channelTape InputsType RCA Female, unbalanced (stereo pair)Maximum Input Level +12 dBuMain OutputsType XLR Male, balancedRated Output Level +24 dBuOutput Impedance 100ΩMix OutputsType XLR Male, balancedRated Output Level +24 dBuOutput Impedance 100ΩHeadphone OutputType ¼” TRS Female, active stereoMaximum Output 100 mW/ch. @ 60Ω loadFrequency Response 20 Hz – 20 kHz (± 0.5 dB)THD+N 0.01%, 1 kHz, max gain, 20 Hz BW, unwtdS/N Ratio 96 dB, 1 kHz, max gain, 20 Hz BW, unwtdSystem CrosstalkInput to Output -90 dB (Ref = +4 dBu 20 Hz-20 kHz, unwtd)Adjacent Channels -87 dB (Ref = +4 dBu 20 Hz-20 kHz, unwtd)Noise Gate / ExpanderThreshold Range -84 dB to 0 dBAttack Time 0.02s to 500 ms / 0.5 msRelease Time 0.05s to 2sExpander Attenuation Range 2:1 (fixed)Noise Gate Attenuation Range -84 to 0 dBKey Filter 2nd-order, resonant bypass; Q=0.7Key Listen Off, 40 Hz to 16 kHzCompressorThreshold Range -56 dB to 0 dBRatio 1:1 to 14:1Attack Time 0.2 ms to 150 msRelease Time 40 ms to 1,000 msAuto Attack and Release Attack = 10 ms, Release = 150 msCurve Types hard and soft kneeLimiterThreshold -56 dB to 0 dB / -28 dBFSRatio ∞:1Attack 20 msHold 10 msRelease 20 msParametric EQType 2nd-order shelving filterLow (Lowpass or Bandpass) 36 to 465 Hz, ±15 dBLow Mid (Bandpass) 90 Hz to 1.2 kHz, ±15 dBHigh Mid (Bandpass) 380 Hz to 5 kHz, ±15 dBHigh (Highpass or Bandpass) 1.4 kHz to 18 kHz, ±15 dBQ (sweepable for each band) 0.1 to 4 / Low Q= 0.55, Hi Q=2.0Graphic EQ31-Band 1/3-Octave Controls Center frequencies (Hz): 20, 25, 32, 40, 50, 63, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1k, 1.3k, 1.6k, 2k, 2.5k, 3.2k, 4k, 5k, 6.4k, 8k, 10k, 13k, 16k, 20k.
