SRM (Smart Rails Management) Technology: The Quattrocanali 2404 incorporates patented Smart Rails Management technology, enhancing the amplifier’s efficiency. This feature dynamically adjusts the power supply based on the load, significantly reducing power consumption while maintaining optimal performance. This technology also ensures minimal heat generation, contributing to the amplifier’s longevity and reducing the need for external cooling solutions.

Versatile Connectivity: This amplifier supports both low-impedance loads (from 2 Ω) and 70V/100V distributed lines. Users can configure the amplifier to operate in various setups, mixing different system types to suit specific installation requirements. This flexibility makes it ideal for diverse applications, from small venues to large-scale installations.

Comprehensive DSP Capabilities: The DSP+D versions of the Quattrocanali offer advanced digital signal processing features. Users can control and monitor the amplifier via Armonìa, enabling precise sound tailoring and system management from remote locations. This level of control allows audio professionals to adjust settings without being physically present at the site.

Robust Protection Mechanisms: The Quattrocanali 2404 is designed with extensive protection features. The fully protected circuit design includes clip limiters, DC protection, and short-circuit protection. Additionally, the thermal protection mechanism ensures the output stages operate safely at temperatures up to 80 °C (176 °F). These features safeguard both the amplifier and connected loudspeakers from damage.

Lightweight and Compact Design: Weighing only 7 kg (15.4 lbs) and occupying just 1 RU of rack space, the Quattrocanali 2404 is easy to install and transport. This compact design does not compromise on performance, offering high-grade sound accuracy in a space-efficient package. The use of standard Phoenix connectors for audio outputs enhances compatibility with existing systems.

User-Friendly Features: The amplifier includes user-selectable settings, allowing customization of gain and maximum output power for each channel. Built-in clip limiters can be defeated if desired, providing further control over audio output. The remote control via RS-485 facilitates operational diagnostics, making it easier to manage the amplifier in complex setups.
