Analog input characteristics

Input Connectors	GAIN	Input Impedance	Source Impedance	Input level			Connector
				Sensitivity*¹	Nominal	Max. before clip
INPUT 1-32 *6	+66dB	7.5 kΩ	50-600 Ω Mics & 600 ΩLines	–82dBu (61.6μV)	–62dBu (0.616mV)	–42dBu (6.16mV)	XLR-3-31 type (Balanced) *2
	–6dB			–10dBu (245mV)	+10dBu (2.45V)	+30dBu (24.5V)

*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. QL1: INPUT1-16
