Increasing the volume
In some cases, the volume of the AUX device may be quieter or louder, or the usual maximum possible volume cannot be reached. On some devices, it is possible to adjust the volume separately. In this case, start at a medium volume and increase it gradually. This enables you to determine whether the system is able to play tones at high volume without distorting them.
