The OMNITRONIC ELA-T5 is a passive 100 V audio transformer for amplifiers or speakers without an integrated 100 V transformer. It converts low-impedance audio signals to 100 V signals and provides five selectable RMS power taps: 0.625 W, 1.25 W, 2.5 W, 3.75 W, and 5 W. The transformer supports 4 Ω, 8 Ω, and 16 Ω systems, has a 50–15,000 Hz frequency range, and measures 6 × 3.5 × 3.5 cm.
