INTEGRAL-MA2004

The INTEGRAL-MA2004 is a 2U rack-mount matrix amplifier designed for permanent installation applications. It delivers 4 x 500 W at 4 ohms and integrates a powerful DSP engine with 4 analog inputs, 4 amplified outputs, and 4×4 DANTE digital audio networking, enabling flexible and scalable system configurations.

Control, configuration, and monitoring are managed via ALMA™ software or ALMAweb over IP networks, as well as through third-party systems using OSC (Open Sound Control). DANTE audio channels can be processed internally and routed back into the network when required. The amplifier supports both low impedance and high impedance (70V/100V) systems, ensuring compatibility with a wide range of installation scenarios.

The unit incorporates a full matrix architecture with advanced routing and priority management capabilities, allowing it to operate as a central control element within the system. Internal memory supports more than 100 global presets and over 200 output channel presets, including optimized configurations for DAS AUDIO systems. Each output channel can be configured independently, enabling tailored system setups across multiple zones or speaker models.

Local operation is available via a 1.54” OLED display with rotary controls, providing intuitive access to essential parameters such as input and output levels, preset recall, mute, source selection, link management functions, and priority settings. Signal level monitoring is also available directly from the front panel.

For external integration, the INTEGRAL-MA2004 includes a GPIO (General Purpose Input/Output) interface with 3.3V logic level, ground connection, and eight configurable pins via ALMA™, facilitating control from external devices.

Two of the analog inputs can be configured as microphone inputs with 12V phantom power. The unit also integrates an Ethernet switch for daisy-chain network connections, eliminating the need for external switches. In addition, Wi-Fi and Bluetooth connectivity enable direct wireless operation via ALMAweb.
