Features

►The TP-428 PRO is a newly upgraded and powerful processor. Within this device, there are 4 analog inputs, 2 digital AES3 inputs, and 8 analog outputs. Meanwhile, the 64dit floating point DSP processor with the sampling rate of 96 kHz is selected as the central processor, greatly improving the dynamic range of the signal processing. Overall, the dynamic range data for this device includes 135dB of dynamic range (input) and 120dB of dynamic range (output). In addition, FIR filters are configured in all eight output channels. And there are 10 PEQ segments in each input and output. At the same time, EQ can be set to Bell, High Shelf, Low Shelf, Notch, Allpass, Band Pass, High Pass, and Low Pass. The maximum input/output level is +23dBu.

►Through the operation of the front panel or remote-control application, this device can be connected to a PC or MAC to perform DSP settings. During the parameter setting process, the signal status of each input and output channel is calculated and monitored in real time. This software can be used to control multiple devices simultaneously. In a typical (default) DHCP configuration, the number of machines under simultaneous control can be as high as 250.
