The BKPF-L653 is a AES/EBU distribution board that
operates in single eight-output or dual four-output modes
for 75 Ω AES/EBU signals. Ten BKPF-L653 fit in one 2U
PFV-L10 frame and provide high packing density of up to
80 AES/EBU distribution outputs within 2U rack space.
Features
* Single or dual distribution configuration (selectable with
on-board switch) * Eight distribution outputs from one
AES/EBU stereo pair input * Four distribution outputs from
two AES/EBU stereo pair inputs * 75 Ω unbalanced
AES/EBU inputs and outputs * Automatic cable
equalization * Data re-clocking for jitter reduction
The BKPF-L Series function boards install in the PFV-L Series Interface Units
in any combination with other BKPF-L Series function boards.
