Tender specification: DFM-110 Active line source speaker high frequency module with electronically controlled dispersion The high frequency module is equipped with 16 1" compression drivers. They are arranged in a horn-loaded line. Each driver is operated with its own integrated 120 W Class-D amplifier. Depending on the application, the module can be combined with other high frequency and low/mid frequency modules. The modules are vertically connected to each other via an easy-to-use, integrated mechanism. The integrated DSP technology enables precise control of the vertical dispersion in real time. The vertical opening angle can be adjusted from 0° to 90° in 0.1° increments. The inclination angle can also be adjusted in 0.1° increments from -40° to +40°. Two independently controllable sound beams can be generated. Both beams use the entire line and can be moved along the entire line length. The control as well as the remote monitoring is performed in real time using a PC and software. The module has digital AES/EBU connections and can optionally be supplied with control and audio signals simultaneously via a manufacturer-specific network technology. The signal processing in the loudspeaker module is entirely digital. Factory-integrated presets protect the speaker systems by selective, multi-stage multiband limiting. The user DSP offers comprehensive settings for routing, EQ, delay, X-over, gate, compressor and limiter. These tools are available both on the input and output sides and can be stored in 100 user presets. The frequency transmission range is 1.7 kHz to 16 kHz. The maximum sound pressure level is 148 dB SPL. The module is 224 mm wide and 274 mm deep and thus has extremely compact dimensions. The ballproof enclosure is made of multiplex birch plywood with structured paint. The aluminum rear panel and the steel front grille are powder-coated. The standard color is black. Other colors can be realized on customer request. Equipped with universal power supply (100 - 240 V 50/60 Hz AC) with monitoring of mains voltage, load and temperature to protect the unit. The adjustable Auto Power Save function ensures minimum energy consumption. Silent operation in idle mode thanks to a temperature-controlled fan.
