Low Power Standby is a standard feature on the L1 Pro family of products. If a product is left on with no detectable audio source for four hours, it will enter a low-power “standby” mode. The product is “woken up” by pressing the power button. Using the L1 Mix app, you can disable the Low Power Standby mode so your L1 Pro system will not turn off after four hours with no detectable audio source.
