OT-1020 4ch Voice coil temperature meter<\/a><\/h3>\r\n

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, the stability of measured values has been further improved.\"\"<\/a><\/p>\r\n

OMT-205AH Voice coil temperature meter<\/a><\/h3>\r\n

\u00a0When OMT – 205 A including OMT-205AH system was modified , this system input signal of 600Vp-p using AP-1203.
Measurement can follow the signal source of sine waves, white noise, pink noise, or music source in the frequency range from 20Hz to 20kHz.<\/p>\r\n

\u00a0 The measured temperature and input voltage are simultaneously displayed on exclusive digital displays. For recording of the changing input voltage and temperature, two DC output terminals are provided and simultaneously recorded to show the relationship between the two.<\/p>\r\n

\u30fbThis unit can use BTL power amplifier as well as single-ended power amplifier.<\/p>\r\n

Optional unit : Data Recorder Model OT-1009<\/a><\/p>\r\n
