Inputs

Switch L position : RCA analog input x 8
Switch B position : XLR analog input x 2
Switch A position : RCA analog input x 2
Trigger in (DC 0V~15V). Floating or (DC 3V~15V) as running ; less than 0.7V as standby.
Outputs

Stereo Speaker Out x 8
Line Out : XLR analog Out x 2 , RCA analog Out x 2
Trigger Out (12V,＜0.1A)
DC 5V Output via Type-A USB Connector (Maximum output 1.6A) x 2
Inputs switch:

L: Each channel has an independent input (Line In)
B: All inputs are transmitted through XLR cable (Bus B)
A: All inputs are transmitted through RCA cable (Bus A)
Bus Function:

Bus L: When the switch is in the L position (Line In), each channel has an independent input to drive each corresponding speaker output.
Bus B : When the switch is in the B position(Bus B), all inputs are transmitted through Bus B XLR cable , the left channel drives speaker outputs 1, 3, 5, and 7, the right channel drives speaker outputs 2, 4, 6, and 8 and Bus Output can feed Bus Input of another MCX-800MZ.
Bus A: When the switch is in the A position(Bus A), all inputs are transmitted through Bus A RCA cable , the left channel drives speaker outputs 1, 3, 5, and 7, the right channel drives speaker outputs 2, 4, 6, and 8 and Bus Output can feed Bus Input of another MCX-800MZ.
