XDA-1204

OMNITRONIC XDA‑1204 – 4‑Channel Class‑D PA Amplifier, 4×300 W (4 Ω)

SKU: XDA‑1204

Product Description

The OMNITRONIC XDA‑1204 is a lightweight 4‑channel Class‑D PA amplifier designed for professional installations, mobile setups and commercial sound reinforcement. Its integrated switch‑mode power supply ensures extremely low weight and a compact 1U rack profile, making it ideal for tight rack spaces and portable systems.

The amplifier delivers 4 × 300 W RMS at 4 Ω, 4 × 180 W RMS at 8 Ω, or 2 × 600 W RMS bridged (8 Ω / 100 V), providing flexible power options for multi‑zone installations, distributed audio systems and high‑performance speaker arrays. Selectable operating modes — stereo, parallel, or bridged — allow precise adaptation to different system designs.

Protection circuits include soft‑start, overheat, overload, short‑circuit and DC protection, ensuring stable operation in demanding environments.
