Some questions for sa750

1

Hi . I am using JBL SA750 with 4312
I have few questions for da750

  1. Sometimes, when turning on the device…
    power relay clicking sound occurs more than 5(?)tims
    (Clinking clicking… turn on)
    Why is it like this?

  2. I usually use it in standby mode (power button on the back, JBL logo on the front stays red). Sometimes I don’t use it for more than 3 days. Wouldn’t it be better to turn off the power completely when not in use?

Thanks for reading this.
Hope you’re doing everything well.
