The Q-Sys PTL-1 (Pilot Tone Load) is a circuit that provides a 22 kHz impedance “soak” at the end of a 70V/100V loudspeaker line. When used in combination with a QSC DataPort amplifier or CXD-Q amplifier and Q-Sys, the PTL-1 becomes a vital component in the real-time monitoring of each loudspeaker line. When a 22 kHz pilot tone (outside of the audible range of human hearing and undetectable above the program material) is transmitted along each loudspeaker line, Q-Sys Designer is able to easily detect a deviation in the impedance at 22 kHz. A significant drop below a pre-determined impedance will signify that a short-circuit has occurred, while a significant rise above a pre-determined impedance will signify that an open-circuit has occurred.
Each failure scenario will generate time-stamped events into the Q-Sys Event Log, and even trigger alert messages if desired. The system designer can select whether the pilot tone is only generated during a scheduled maintenance check, or whether it is always active and providing real-time diagnostics on every zone.
