{"product_id":"lem-commercial-d-drive-1-2k4h-ae","title":"LEM Commercial D-Drive 1.2k4h-ae","description":"\u003ch3\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/h3\u003e\u003cp class=\"MsoNormal\"\u003eThe D-Drive 1.2k4h-AE is the new compact 1\/2-rack amplifier from LEM Commercial, designed to offer high performance, advanced management, and maximum reliability in modern fixed installations. It is part of a new generation of power amplifiers with integrated DSP, all sharing a web-based control platform that allows for configuration and monitoring from any browser, without the need for dedicated software.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe heart of the D-Drive 1.2k4h-AE is a high-performance DSP based on the ADI Sharc platform, capable of managing a full 4 × 4 matrix and a set of extremely advanced processing functions. The processing includes high-resolution FIR filters, parametric and dynamic equalizations, compressors, expanders, and per-channel delay, with the possibility of using presets dedicated to both the device and the loudspeakers.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe power section utilizes proprietary Class-D technology with independent converters, designed to provide low background noise, linear frequency response, and a rated power of 4 × 150 W into low-impedance loads. The compact 1\/2-rack format allows for easy integration in installations where space is limited, while maintaining the same philosophy of efficiency and reliability as the higher-tier model.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eControl is managed via Webcon, an integrated web interface that offers simultaneous multi-user access, compatibility with any browser on PCs, tablets, and smartphones, and a unified workflow for managing multiple devices. The platform allows for real-time monitoring, level management, muting, device identification, configuration of GPIOs, IP wall panels, and the use of open APIs for integration with third-party systems.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIn terms of connectivity, the D-Drive 1.2k4h-AE features analog inputs as well as AES\/EBU and AES67 digital inputs, ensuring high flexibility for integration into networked audio systems. The outputs are available on Euroblock and\/or speakON connectors, while the front panel hosts a modern interface optimized for the 1\/2-rack format, designed for compact installations and multi-zone systems. A dedicated blank panel allows the amplifier to be mounted in a standard 19” rack space, or two D-Drive 1.2k4h-AE units can be mounted in the same width using the two side ears and a top metal fixing plate.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe cooling system uses a configurable, thermally controlled fan, which ensures consistent performance even under heavy conditions. The wide-range power supply ensures full compatibility with international electrical grids, while system protection is handled by a complete set of intelligent functions: automatic HF signal inhibition, protection against overvoltage, short circuits, overtemperature, and other critical conditions.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eFrom a construction standpoint, the D-Drive 1.2k4h-AE uses audiophile-grade components, including high-quality operational amplifiers, resistors, capacitors, and selected driver chips, to ensure a clean and natural audio output.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe D-Drive 1.2k4h-AE therefore represents a new-generation compact amplifier that is powerful, efficient, and designed to integrate naturally into modern professional audio ecosystems. The combination of advanced DSP, high-efficiency amplification, native web control, and networking options makes it an ideal choice for installations requiring quality, reliability, and centralized management in restricted spaces.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003e\u003cspan style=\"color: #00b050;\"\u003eUser benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 0cm;\"\u003e\n\n\u003cli class=\"MsoNormal\" style=\"mso-list: l1 level1 lfo1;
