The DS-6 D/A range extender is used in the DS-6 decentralised PA system as well as in the higher-level TIMM system.

It enables a monitored control of an amplifier with a loudspeaker circuit over a distance of up to 6 kilometres to the DS-6 node. For universal use, several supply options are available for the DS-6 D/A range extender. The standard connection of the DS-6 D/A range extender is via a local power supply, in the immediate vicinity or via the amplifier.

In addition, the DS-6 D/A range extender can be supplied directly via the DS-6 mains node. Phantom powering (two-wire operation) for shorter distances is also provided. With phantom powering, the DS-6 range extender can be powered directly via the U_k0connection line, so no additional power supply is required.

Connected amplifiers can be monitored for failure via a potential-free fault signal input and these fault signals can be forwarded via the DS-6 or TIMM system.

For industrial operation, the board provides a potential-free line/contact for switching on the connected ampli- fier. The DS-6 D/A range extender requires a free U_k0 port on the DS-6 U_k0 II adapter.
