Mcintosh PF-4025i-D mini-disc & CD 2DIN car radio, with AUX. The Burr Brown PCM-1710U DAC is responsible for the high-quality sound. 

Made in Japan. Radio is also Japanese, need a frequency converter. It's in the kit. With it, FM stations are good and stable. I would be happy to convert this head unit to 107.9 FM, but unfortunately in this particular model the processor does not support it, need to unsolder it, reflash and re-solder to the board, and then there is a high probability that the minidisc mode will be lost((.

Includes Addzest Japanese-made six MD changer with full control from Mcintosh head unit (including titles) and optical output.

Its built-in amplifier head unit has no, so it installed RCA-outs to external amplifiers, there is a wire control inclusion of the amplifier. To clarify: In the original, these are balanced outputs, so if your external amplifier supports switching to this mode, it is better to use a balanced line. But it also works with simple amplifiers.

Also added AUX, an external input for any audio device, and the music through it sounds great! On and off AUX mode is controlled by the T.I. button on the front panel. Very convenient. The original Japanese T.I. mode and AM radio, respectively, do not exist, they are removed from this head unit. 
If the buyer needs it, I'll convert everything back to a Mcintosh amplifier. The amplifier and cable are also available, but at an additional cost.

Of course the minidisc and CD work, the mechanisms are fully serviced and lubricated, the laser heads are cleaned. The head unit was completely disassembled to the last bolt, all body parts were cleaned of dirt and grease, handles and buttons were disinfected.
