Description

NEW – Returned shipment The amplifier module with integrated DSP is intended for installation in active loudspeaker systems. With three amplifier channels, it is suitable for both 2.1 systems and active three-way loudspeakers. The two identically configured channels each deliver 450 W at 8 Ω, while the third channel provides 900 W. At 4 Ω, 2 × 720 W and 1440 W on the third channel are available. The integrated DSP has four channels, of which outputs A, B and C can be used. Output D remains unused on this module. Two balanced XLR inputs are provided for signal input; two parallel audio outputs enable integration into the internal signal distribution of the loudspeaker system. Configuration can be carried out either via the encoder on the module or by software. Speakon connectors or KF25C-7.62 screw terminals are available for the loudspeaker paths. The DSP provides input and output EQs, high-pass and low-pass filters, delay and a peak limiter. Up to 20 user presets can be stored. The frequency range extends from 20 Hz to 20 kHz.

The two amplifier channels with identical output can power two loudspeaker paths, while the more powerful third channel is intended for another path. The unit is integrated into a balanced audio signal path via the two XLR inputs. The connection to the loudspeaker paths is made via Speakon or KF25C-7.62 screw terminals. To adapt the system, input and output signals can be processed using EQ, and high-pass, low-pass, delay and limiter functions can be used. The settings can be made directly on the encoder or via the software and then saved as presets. When planning and installing, the output powers, connected impedances, required operating voltage, installation dimensions and channel assignment must be matched to the respective loudspeaker design.
