System information
Figure 4: Block diagram
Two-channel active amplifier with DSP filter control.
Description
The PSC2 is a plate amp for use in powered speaker systems. As an active speaker controller, a PSC2
can form the basis of a powerful active two-way monitor.
Figure 4 shows the audio path of the PSC2. The module has two 400Watt UcD modules implemented
and is also available with a digital audio input AES/EBU, called the PSC2.400d version. The supply
voltage is provided by a Switched Mode Power Supply (SMPS400) module, also a module from Hypex
Electronics.
A PC controls the PSC2 through the USB port. This connection is used to upload the configuration
and filter settings. It will also be possible to update the firmware through USB.
