Features of CRI ADX™AT
Adv. 1 Sound design on real machines
The sound quality can be reproduced in the production environment, and the sound source can be created
while checking it in real time.
Volume adjustments are measured on the actual vehicle, and the set values can be determined and
completed on the spot.
Adv. 2 Rapid response to small-lot car models and deliveries
It can be simply handled by replacing the sound source data, and can also be applied via OTA (Over-the-Air).
On the other hand, the same sound source data can be used without modification,
even if the hardware is different.
Adv. 3 Low power consumption and high volume
Unique full-digital amplifiers provide highly efficient output.
And it contributes to efficiency by reducing cost, mounting area, and power consumption.
