BKPF-L754
The BKPF-L754 is an audio signal generator board that has a dual audio signal generator. Each signal generator can be selected between 1 kHz and 440 Hz (440 Hz or 400 Hz is selectable) via GPI or the on-board switch. Three outputs of each of these two signals are provided. Normally the left and right channels carry the same frequency, but they can be switched to carry different frequencies.
The BKPF-L754 is especially of use as an audio identification for video sources, or as a centralized tone source.
BKPF-L Series function boards can be installed into PFV-L
Series Interface Units in any combination.
