5. REAR PANEL

The rear panel features following connections:

Mains socket

The DP400 features a 3-pin IEC socket for mains supply. The fact of having a switched mode

power supply, allows the use of a wide range of mains specifications: from 90 to 264 VAC at frequencies
between 47 and 63 Hz. Before switching on the unit, please ensure that the DP400 is connected to earth
and that the electrical installation fulfils the local safety regulations.

Input Connectors (CH1, CH2) and Output Connectors (Output 1-6)

The DP400 has two inputs (CH1 and CH2) on three-pin female XLR sockets. The pin layout is

following: Pin 1 is Ground, Pin 2 is +signal (hot) and Pin 3 is –signal (cold). The six outputs of the DP400
(OUTPUT 1-6) are on three-pin male XLR sockets. As in the input connectors, Pin 1 is Ground, Pin 2 is
+signal (hot) and Pin 3 is –signal (cold).
