Mackie DX8 instruction manual SIGNAL-FLOW Diagram, Outputs A/B

RECORD Out

These RCA connectors supply unbalanced line-level signals from the BUS A and BUS B outputs. Use these outputs to connect to the inputs of a recorder, or as additional line-level outputs to connect to an external power amplifier. The signals are the same as the main outputs.

OUTPUTS A/B

These 3-pin Phoenix-type connectors supply a balanced line-level signal from BUS A and BUS B.

LOGIC I/O

This 25-pin D-Sub connector provides 10 logic control inputs and 10 logic control outputs (open- collector). These inputs can be used to control a wide variety of DX8 functions via external switching. The outputs can be used to provide logic for external indicators for a number of internal settings and conditions. The function of each logic input and output can be programmed via software to suit individual applications. See page 13 for the Logic I/O pinouts.

REMOTE BUS

This 3-pin Phoenix-type connector can be used to attach optional remote controls to the DX8. Several

remote controls can be connected to each other in a daisy-chain fashion to extend the remote control functionality of the DX8.

COMM PORT

This is identical to the COMM PORT on the front panel. Use this to connect to an RS-232 serial port on a personal computer or third-party controller (i.e., show controller) for external control of the DX8.

EXPANSION SLOT

The optional DX10e card can be installed here. It provides eight additional independent balanced output mixes.

24 VDC POWER

The DX8 can be powered using a 24 VDC power supply. This can serve as the primary power supply for the DX8, or as a backup supply in case of an AC power failure. The DX8 seamlessly switches to the backup supply if there’s a power loss. When both AC power and 24V DC power are connected, the AC power is used and no current is drawn from the DC supply.

IEC AC Socket

Connect the supplied AC linecord to the IEC AC socket.
