About the CD-400B
The Marantz CD-400B is a specialized demodulator that extracts four discrete audio channels from CD-4 encoded records, enabling true quadraphonic playback. It features an automatic noise reduction circuit to minimize record noise without affecting frequency response, and an automatic carrier level control that optimizes performance for the cartridge in use. The unit can also process non-CD-4 records without adjustment, automatically detecting the format and switching modes as needed. Built for high fidelity, it includes proprietary noise reduction and crosstalk reduction technologies for enhanced playback quality. The CD-400B is switchable between 2-channel and 4-channel modes, making it versatile for both stereo and quadraphonic systems.
