Input/Output Specifications Analog input specifications Input Connectors INPUT 1-32 *6 Gain +66dB -6dB Input Source Impedance Impedance Sensitivity*1 7.5 kΩ 50-600 Ω Mics & 600 Ω Lines -82dBu (61.6μV) -10dBu (245mV) Input Level Defined Level -62dBu (0.616mV) +10dBu (2.45V) Maximum Connector Non-Clip Level -42dBu (6.16mV) +30dBu (24.5V) XLR-3-31 type (Balanced)*2 *1. The sensitivity is the input level required for output at +4dBu (1.23V) or at the defined level when all the faders and level controllers are set to the maximum value. *2. XLR-3-31 connectors are balanced jacks (1=GND, 2=HOT, 3=COLD). *3. 0dBu=0.775 Vms for all specifications. *4. All the AD converters use 24-bit linear/128-times oversampling. *5. The INPUT connectors have +48V DC (phantom power) jacks, each of which can be turned on/off individually from the console software. *6.

XLR-3-32 connectors are balanced jacks (1=GND, 2=HOT, 3=COLD). *2. The PHONES connectors for stereo headphones are balanced jacks (Tip=LEFT, Ring=RIGHT, Sleeve= GND). *3. 0 dBu=0.775 Vms for all specifications. *4. All the DA converters use 24-bit linear/128-times oversampling. *5. The console has an internal switch for toggling the maximum output level. *6. This is a value measured with the PHONES LEVEL knob set to 10 dB below the maximum position. *7.
