LC1-PIB Pilot‑tone Indication Board The loudspeakers have provision for optional mounting of the Pilot‑tone Indication Board. This small PCB with LED can fixed into a holder, connected to a light conductor standard fitted. The presence of the pilot‑tone can be visually checked by means of the flashing of the LED, integrated in the front grille rim. The required level of the pilot tone signal is 4 V rms @ 20 kHz and the load to the amplifier from these boards is negligible.
