No idea on the chipset. No voice prompts or beeps - the only indication of interaction is via led. I have not done much testing - just connected to my win10 laptop and a spare set of Kenwood speakers (6Ohm 40W) and very happy with the result. This unit is made in ChinaNakamichi seems to be one of the last Japanese manufacturers still making audio equipment.
Do you know if they are using a CSR/Qualcomm chipset or a Chinese one? Does it have English/British voice prompts
or just beeps to indicate the different modes?
