OT-1020 is a thermometer that measures the temperature of the speaker’s voice coil unit. It follows any signal source (sine wave, white noise, pink noise, standard load test noise, music source) from 20Hz to 20kHz.
Displays graphs and values of temperature and input voltage versus time.
A BTL amplifier can also be used, and this unit can be controlled simultaneously by one PC (up to 5 units), and up to 20 voice coils can be measured simultaneously.
In addition, compared to the conventional model (OMT-405), the stability of measured va lues has been further improved.
