The LF Audio WTH-PRO is a wireless temperature monitoring hub built to keep an eye on the heat inside extreme car audio builds, supporting up to 16 sensors split between 8 infrared and 8 thermocoupling probes. It streams real-time readings to the AuralSync app, WVC Knob, WDD, or WDD-LITE, and multiple WTH-PRO units can be linked together to cover a large installation.

Industrial differential signaling filters out the electrical noise thrown off by high-amperage cabling and digital amplifiers, so readings stay stable near power distribution blocks, amplifier banks, and high-output alternators. Up to four custom temperature zones per component can be configured, giving clear visual cues as temperatures approach critical thresholds.
