Low Voltage Wiring Instructions for DSP420
NB. THE PRE-ASSEMBLED TERMINAL BLOCK SHOULD BE UNPLUGGED FROM THE PCB SOCKET PRIOR TO CONNECTION
The DSP420 requires the following connections:
1. Comms Input (pins 9&10)
2. Digital Audio Input (pins 13&14)
The Slave link (Pins 7&8) should be fitted for a Slave speaker and removed for a Master speaker.
If it is to be daisy-chained to a further speaker it requires the following additional connections:
3. Comms Output (pins 5&6)
4. Digital Audio Output (Pins 11&12)
If IR input is required from a sensor such as a Meridian 512, this can be connected to pins 1 to 3.
Typical connections are shown in the diagrams below.

Ground (see below) 11 Dig Out Digital Output to next speaker 12 D.O. Ground 13 Dig In Digital Input from other speaker or 14 D.I. Ground system
Meridian Digital Link is a suitable cable for the Comms and the Audio but is not UL approved. If alternative cable is
needed, the following specifications should be followed.
Comms: Single screened cable, 100pF/m or less
Digital Audio: 75 Ohm Coaxial cable, shielded with braid and foil
