Lo-D D-X10 cassette deck front panel

The grand master of the Lo-D (by Hitachi) stereo cassette range, the DX10 is the connoisseurs choice for superlative sound reproduction. The Lo-D D-X10 is a high-end 3-head, direct-drive, auto-reverse cassette deck designed with sound quality as its top priority. This model represented Hitachi’s peak engineering under the Lo-D (Low Distortion) brand. Advanced 3-Head Reverse Design: The D-X10 features a newly developed titanium-sprayed R&P combination head with a precision reverse mechanism. The recording and playback heads are spaced just 1.4 mm apart, ensuring minimal loss and optimal tape-to-head contact. The rotating head uses a compact, high-precision ball bearing for ultra-smooth, stable rotation—maximizing the advantages of a true 3-head system. ATRS Automatic Frequency Response System: The ATRS (Automatic Tape Response System) uses a built-in computer to automatically measure and adjust the bias, recording sensitivity, and equalization for any tape type. It guarantees flat frequency response across almost all commercially available tapes. Preset test data is stored for metal, chrome, and normal tapes to ensure consistent results. Precision Tape Transport: A magnetic back-tension system keeps the tape in perfect contact with the head in both forward and reverse playback. The Uni-Torque Direct Drive motor ensures 0.03% wow & flutter (WRMS) and stable tape motion. The deck also includes a TF-55 Unitorque brushless motor for silent, vibration-free performance.
