Harman/Kardon 400XM cassette deck

 High technology metal cassette deck

The hk400XM is our top of the line cassette deck, and offers you the best of both worlds. High performance. And the sophisticated operating controls normally found only in professional equipment.

To start with, the 400XM is the most sophisticated design we ofer, with Dolby HX headroom extension, soft touch solenoid controls for fast, easy transport control, a two-motor transport for low wow and flutter (only 0,03%), and a 3-head configuration for simultaneous monitoring during the recording process.

Frequency Response is flat (±3 dB) for 15 to 20,000 Hz, with a Signal-to-Noise Ratio of 68 dB, using Metal tape and Dolby circuitry.

The 400XM's separate bias and equalization controls, tone generators and playback calibrators allow you to control all facets of the recording process for perfect results no matter which tape formulation you choose. LEDs indicate headroom safety to prevent saturation. We've even included a special shifting Dolby mark on the record level indicators. With conventional tape formulations, the Dolby mark remains in its normal position. But when metal tape is used, the Dolby mark automatically shifts upward to remind you of the new, higher setting you can use.

In addition to our Auto Program Search System, which lets you scan forward or backward automatically to sample each selection on the cassette, the 400XM also features an auto rewind/replay system. Engage the rewind system and when the tape ends the deck will automatically rewind the tape to its beginning. With both rewind and replay engaged, the deck will replay the tape automatically, too, rewinding and replaying each time the cassette ends.
