4-kanavainen Class-D päätevahvistin Omnitronic XDA-1204 1200W RMS

The Omnitronic XDA-1204 4-channel Class-D amplifier delivers 1200W RMS in a compact, energy-efficient chassis designed for professional audio installations. The unit provides four independent output channels with Class-D topology, offering high power density and reduced heat generation compared with traditional amplifier classes. Built for continuous operation in fixed installations, small live sound rigs and event setups, this amplifier supports powering multiple speakers or zones from a single device while minimizing power draw and rack space.

Advantages

The Class-D design provides a high efficiency-to-power ratio, resulting in lower heat dissipation and reduced cooling requirements. Four channels allow flexible routing and multi-zone operation without additional amplifiers. Its compact form factor and professional connectors simplify rack mounting and integration into existing audio systems. The unit delivers consistent RMS power across channels, enabling reliable long-term performance in installations and event environments.

Key specifications

How to use

Install the amplifier in a ventilated rack space and connect line-level sources to the corresponding inputs. Configure the outputs to the appropriate speaker channels, observing speaker impedance and power handling to avoid overload. Adjust gain and any onboard level controls to match source levels and room acoustics. Ensure proper grounding and secure cabling; verify operation at low levels before applying full power. Routine inspection of connections and ventilation paths helps maintain consistent performance.

Recommendations

For reliable long-term operation, allow sufficient airflow around the amplifier, match speaker impedances to the amplifier’s recommended range, and avoid continuous operation at maximum RMS power to extend component life. Use balanced inputs where possible to reduce noise in installed systems.
