MX400 User’s Guide
* 0dB=0.775V R.M.S
Input Specifications
*1. Sensitivity is the lowest input level that will produce an output of +4dB (1.23V) or the nominal output level when MX400 is set to
maximum gain (i.e. all level controls and faders set to maximum).
*2. XLR-type connectors and phone jacks (TRS) are balanced (Tip=HOT, Ring=COLD, Sleeve=shield).
*3. Insert phone jacks (TRS) are unbalanced (Tip=out, Ring=in, Sleeve=GND).
*4. Phone jacks are unbalanced.
*5. The talkback jack is unbalanced.
*6. In these specifications, when dB represents a specific voltage, 0dB is referenced to 775mV RMS,and when dBV represents a specific
voltage, 0dBV is referenced to 1V RMS.
