ELA controller Omnitronic ELA-LS-Regler/Prog-Waehler 20W 18kHz Mono

Omnitronic ELA-LS-Regler/Prog-Waehler 20W 18kHz Mono is a mono ELA controller designed for level control and program selection in public address (ELA) systems. With a 20 W output and an 18 kHz specification, this unit is intended for paging and background music in shops, offices and small venues. The device integrates with existing ELA installations to provide straightforward volume adjustment and switching between program sources while preserving speech clarity and music fidelity within its specified frequency range.

Advantages

The controller provides precise level control for a mono ELA line and allows selection between program sources without complex configuration. Its 20 W output is suitable for small- to medium-scale distributed audio systems, and the 18 kHz frequency characteristic ensures reproduction of the upper audio band relevant for intelligibility and musical content. The unit is compact and designed for simple integration into public address setups, reducing installation time and operational complexity.

How to use

Connect the controller to the ELA distributed audio line following the device's connection diagram and ensure the system power is turned off during wiring. Route input sources to the program selection inputs and connect the output to the ELA amplifier or speaker line. Power up the system and use the level control to set an appropriate background music or paging level; switch between program sources as needed. Verify speech intelligibility and that the output level does not exceed the recommended level for the connected speaker line.

Recommendations

Place the controller in a dry, ventilated location away from strong electromagnetic interference. Perform level adjustments at typical operating volume and test page announcements from several positions to ensure even coverage. For larger distributed systems or where zoning is required, combine this unit with additional ELA components designed for multi-zone control and appropriate load matching.
