Questions about this item

Does the 9.0 V adapter run hot or draw much power when the SoundBox is on all day?

The adapter accepts 100-240 VAC at 50/60 Hz and delivers a steady 9.0 V output, so heat and power draw stay modest during continuous use.

What must I already own to use this 3.19 mm plug adapter?

You need a Serene Innovations TV SoundBox that takes a 3.19 mm barrel connector at 9.0 V DC.

Will this 9.0 V supply work with an older SoundBox that used a different voltage?

Only if the older unit also requires exactly 9.0 V DC through a 3.19 mm jack; otherwise the voltage mismatch could cause damage.
