14.The left and right channels imbalanced? (one side is louder than the other)?

RR11 uses a purely analog circuit. The analog circuit is characterized by a warmer sound, more durable. But due to the limitations of the potentiometer process, a slight difference in material (potentiometer left and right channel slightly material differences) will cause the volume difference.

Especially at low volumes, the volume imbalance phenomenon may be more pronounced.

RR11 has been selected by us at the factory. The products from the factory are within the standard range, so you can use them with confidence.
