The thermal design allows the amplifier to maintain optimal performance levels without overheating, ensuring long-term stability in various applications.

Versatile Connectivity: The QUATTROCANALI 2404 DSP+ is engineered to support both low-impedance (Lo-Z) loads starting from 2 Ω and 70V/100V distributed lines. This flexibility makes it suitable for a wide range of installations, from live events to fixed installations in commercial spaces. Users can mix different load types, tailoring the system to their specific needs.

Advanced DSP Capabilities: The DSP+ version of the amplifier offers extensive control and monitoring options via Armonìa software. Users can easily customize audio settings and manage the system remotely, which streamlines operations in complex setups. The integration of AES67 digital audio networking enhances signal routing capabilities, allowing seamless connectivity with other digital audio devices.

Robust Power Supply: The amplifier features a cleverly engineered power supply that ensures reliable operation even in mission-critical applications, such as fire alarm systems. This design guarantees consistent performance when connected to an Uninterruptible Power Supply (UPS), providing peace of mind in critical situations.

Comprehensive Protection Features: The QUATTROCANALI 2404 DSP+ includes a fully protected circuit design with multiple safety features. These protections encompass AC voltage protection, clip limiters to prevent distortion, DC protection, and thermal protection. Furthermore, the automatic reset for short circuit protection ensures that the amplifier remains operational during unforeseen events, safeguarding both the unit and connected loudspeakers.

Compact and Lightweight Design: Weighing just 7 kg (15.4 lbs) and occupying a single rack unit (1 RU) of space, this amplifier is compact and lightweight. This design facilitates easy installation, racking, and transport, making it ideal for touring professionals and fixed installations alike.

Remote Monitoring and Control: Users can remotely monitor and control the amplifier through various interfaces, including the RS-485 connection for diagnostics and operational settings. This capability provides full system oversight, enhancing user experience and enabling quick adjustments when necessary.
