Hello, The SM-621 speaker was purchased for a hard of hearing individual. She has had complaints from other residents in her complex that the TV is too loud after 9 pm. She refuses to use the headphones and tends to go to sleep with the tv/speaker on. Does this speaker have a sound limiting option? Or, can that function be controlled through the tv setting. Also, does it have a sleep setting that will automatically turn off the speaker even with the tv still on?

The SIMOLIO SM-621 speaker has Automatic Signal Control (ASC), which stabilizes volume and prevents sudden loud sounds, acting as a sound limiting option. However, there is no mention of a sleep setting that automatically turns off the speaker.
