Audio transformer Omnitronic ELA-T100 100W – line matching transformer for 100 W PA systems

The Omnitronic ELA-T100 100W is a line-matching audio transformer designed for use in 100 V public address (PA) speaker systems. It provides impedance and level matching between amplifiers and long-distance 100 V speaker lines, ensuring consistent audio distribution and reducing power loss across distributed loudspeaker networks. The transformer is intended for fixed installations where multiple speakers are connected to a central amplifier over extended cable runs.

Advantages

The Omnitronic ELA-T100 supports efficient power transfer and helps maintain signal integrity on 100 V lines. Its design enables accurate level matching to protect amplifiers and speakers while minimising hum and interference in distributed systems. Compact construction and straightforward integration into existing PA setups make it suitable for a variety of installation environments.

Key specifications

How to use

Install the transformer between the amplifier output and the 100 V speaker line, following standard wiring practices for distributed loudspeaker networks. Select the appropriate tap or connection to set the required speaker power level and match the amplifier load. Ensure secure mechanical mounting and proper cable connections to avoid signal degradation. Verify correct operation by testing the system at low volume before normal operation.

Recommendations

Use the Omnitronic ELA-T100 in systems that require reliable line-matching for 100 V speaker networks. Match power taps to the speaker requirements, maintain correct grounding and observe recommended cable runs to minimise interference and maintain even distribution of audio throughout the installation.
