Easy measurement with the push of a button! A wide-range audio tester with a measurement frequency of 10Hz to 90kHz.
The "OT-1003" is an audio tester that measures and evaluates using digital processing. The measurement frequency range has been expanded to 10Hz to 90kHz, compared to the conventional OAT-900 (20Hz to 20kHz), making it suitable for measuring and evaluating so-called high-resolution products. After creating the reference data for evaluation, measurements can be performed with the push of a single button, making operation very simple. 【Products that can be measured】 ■ Stereo headphones ■ Stereo handsets (stereo headphones + microphone) ■ Handsets ■ Receivers (speakers) simultaneously for 2 units (or 1 unit) ■ Microphones *For more details, please download the PDF or feel free to contact us.
