Marantz CD400


The Marantz model CD-400B is a simple to operate demodulator for obtaining four discrete channels from CD-4 records.

The unit incorporates an automatic noise reduction circuit to minimize record noise without affecting frequency response, and an automatic 30Hz carrier level control which selects the optimum carrier level for the cartridge being used.

Non CD-4 records may also be played through the CD-400B without affecting their performance.

The controls do not have to be adjusted to play non CD-4 records; when they are played and the mode switch is in the 4 CH Auto position, the Radar indicator will illuminate and the record will automatically be demodulated into four discrete channels.

re: CD400

ThereĀ“s an missprint. CD-4 Carrier signal is a 30KHz and not a 30Hz ! Anyone have a CD-400B version service manual or least a circuit schematic ? Thanks before hand.
