*1. INDP7, 8 are set by terminal resistor common to main source and mixing source (simultaneous use is also available).
*2. INMPN and INMN are input dedicated to mixing. If differential is received by ISOLATOR, they become negative input of INDP8.
*3. At single input, receipt of 8ch by ISOLATOR becomes 4CH.
*4. Digital Audio Input can be also set to output depending on setting of resistor.
