5. REAR PANEL
The rear panel features following connections:
Mains socket
The DP300 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 DP300 is connected to earth
and that the electrical installation fulfils the local safety regulations.
RS-232 socket
A 9-pin SUB-D connector for serial RS-232 communication is provided at the rear panel. This
connector allows bi-directional communication between the DP300 and a PC in order to remotely control
the parameters of the processor via software.
MIDI Sockets
Three 5-pin DIN connectors provide MIDI communication. MIDI IN, MIDI OUT and MIDI THRU
are provided.
Input Connectors (CH1, CH2) and Output Connectors (Output 1-6)
The DP300 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 DP300
(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).
