Microphone preamp with volume and tone control compatible with the T-8000 matrix.
The T-8000C and T-8000D are remote control boards that are connected to the T-8000 matrix via standard universal CAT5 cable when there is a need to adjust the volume of sources or make calls from remote locations in the matrix. Each control matrix has 8 x RJ45 sockets for remote control from the preamp module. CAT5 cabling is used because of cost, ease of installation, but also because it integrates RJ 485 communication, audio transmission and 24 V power supply at the same time. This family of modules also includes a more complex model the T-8000B.
