PA amplifiers for fixed and mobile sound systems – from compact mono power amps to high-power multi-channel units. 100-volt technology and low-impedance versions for every application.

100-volt technology (ELA): In 100 V systems all loudspeakers transform via line-matching transformers onto the shared 100 V bus – thin cable cross-sections even over long distances (up to 1,000 m), unlimited speakers in parallel, easy zone control via volume attenuators. Typical applications: department stores, schools, railway stations and public buildings. Low-impedance (4–16 Ω): Direct amplifier–speaker connection, higher audio quality, minimal power loss – ideal for short cable runs and high-quality audio.

Key features: balanced XLR/RCA inputs, limiter circuit to protect connected loudspeakers, short-circuit and over-temperature protection, zone control for up to 8 independent coverage areas, emergency-paging input with priority switching to EN 60849 standard. Form factor: 19-inch rack mount (1–4U) or compact table-top units.
