About the product:

The Sony TC-K44 incorporates many of the outstanding features of the TCK22, including metal tape capability, Dolby noise reduction, and the Tri-Duty DC servo motor.

To these, the K44 adds a frequency generator servo system, for even better tape speed stability, a Sendust and Ferrite head and LED Peak Program Meters.

Recording levels on the K44 can be monitored on bright, sixteen segment, light emitting diode (LED) Peak Program Meters. Because LEDs have no mechanical inertia to overcome, they can follow the transient peaks of music with outstanding accuracy.

The K44 has the same complement of convenient controls and operating features as the K22. plus three additions.

First is punch-in recording, the ability to go from the Play mode directly into the Record mode, without first pressing Stop. punch-in recording permits more professional results when taping material onto a previously recorded track.

Second, the Record Mute allows you to blank out broadcast commercials and other interruptions, while remaining in the Record mode.

Third, and finally, the K44 incorporates a volume control for manual adjustment of the headphone output levels.
