The BKPF-L753A analog audio distribution board
distributes an analog stereo audio signal to four outputs or
an analog monaural audio signal to eight outputs. A gain
control allows the input reference level to be varied
between -4 dBm and +12 dBm. Phoenix type connector
for each distribution block carries its input and output
signals.
Features
* Single or dual distribution configuration (selectable with
on-board switch) * Eight distribution outputs of a mono
analog audio input * Four distribution outputs of a stereo
analog audio input * Low noise * Gain control function
The BKPF-L Series function boards install in the PFV-L Series Interface Units
in any combination with other BKPF-L Series function boards.
