Sony MHC DP1000D. Since it has not been used for a long time, when power is given recently, music plays but the sound is very low even at full volume. I am the 2nd owner, I have not shown it to any mechanic yet. The set's power line is direct. Almost all equalizer switches work. There is no problem with the volume button. It can be connected to anything via AUX line. The sound boxes are simply amazing. You can understand it by playing the sound boxes with any Bengali amplifier. 5-piece set including machine + box. No remote. Those who are interested should come and check it directly. The box + machine must be taken together. I will not sell separately. And please, genuine buyers come, check, and take it.
