Audio Processor-PD Series

Audio Processor-PD Series

The PD series digital divider/system processor has 4 inputs and 8 outputs coupled to the user interface, as well as all audio signal processing tools required for a precise divider and sound control system. It is simple and convenient to use, even without manual manipulation. You can control the gain, delay, and 9 filters of each input (you can set each filter as a parametric filter or high and low pass filters). You can set the frequency of each output and specify any input or any combination of inputs. In addition, 9 filters can be programmed to control (you can select each filter as a parametric filter or high and low pass filters), adjust the delay time and output gain, invert, control the compressor/equalizer To protect the speaker system. The external dimension of this processor is 1 standard rack space, and the input and output are XLR type connectors. 448 is a powerful tool in fixed installation and on-site sound reinforcement systems;
