Bkpf-351 - Sony MK7807V1 Manual Book

Interface Processor D Series

BKPF-351

The BKPF-351 analog audio selector board is an eight
stereo input to one stereo output switching matrix for
analog audio signals. Cross point information is
memorized for 24 hours. Up to four BKPF-350 boards
can be integrated to form a 32 input, 1 output stereo
switching matrix. Inputs are via two D-sub 25-pin
connectors and the output via a Phoenix type 6-pin
connector.The BKPF Series function boards install in both
the PFV-D and the PFV-HD Series Interface Units. In a
PFV-HD Series Interface Unit, they can be installed
together with the HKPF Series function boards.
Features
* Eight analog stereo inputs, one stereo output switching
matrix * Simultaneous control of multiple signals with
matrix level setting * Control from BKS-R Series control
units via S-BUS network * Supports ISR
