The dedicated AC line interface for the professional user.

Particularly suitable for universal use.

The FunkTronic LIM-AC/NL line interface is specially designed to connect especially the new generation control units Major 4a/NL and Major 5a/NL (multi-wire) to a 2-wire PTT (leased) line connection to a transmitter/interface. It also requires the LIM-AC/NL (with an optional built-in notch filter PCB) to suppress the pilot tone if multiple control units are connected in parallel. The FunkTronic LIM-AC/NL is approved according to the European TBR-15 standard.

Key features in brief:

• Connection possibility to a keypad connect to a 2-wire AC line connection
• Transmitter control using a 3300 Hz pilot tone
• Built-in possibility in the LIM-AC for a notch filter PCB to suppress the pilot tone
• Adjustable in/outputs and line level using trimpotmeters
• The asymmetrical In/Outputs are not galvanically isolated
• Supply voltage 12 Volt DC to be fed from the power supply of the base station
