- TDNS (Tape Duplication Noise Suppressor): Reduces noise during tape-to-tape copying, improving the quality of duplicated tapes.
- FLAT System: A feature for optimizing recording characteristics.
- Dolby HX-PRO: Enhances high-frequency headroom during recording, preventing saturation and improving dynamic range.

5. Maintenance
5.1 Cleaning Heads, Pinch Rollers, and Capstans
Regular cleaning is crucial for optimal sound quality and tape longevity. Clean these components after every 10-20 hours of use or if sound quality deteriorates.
- Open the cassette compartment.
- Using a cotton swab lightly moistened with isopropyl alcohol, gently clean the tape heads (record/playback and erase heads).
- Clean the pinch rollers and capstans, removing any tape residue.
- Allow all components to dry completely before closing the compartment or playing a tape.
5.2 Demagnetization
Over time, tape heads can become magnetized, leading to dull sound and increased tape hiss. Demagnetize the heads after approximately 50 hours of use or if you notice a degradation in sound quality. Use a dedicated tape head demagnetizer according to its instructions.
6. Troubleshooting

|---|---|---|
| No power | Power cord not connected; Power outlet faulty | Check power cord connection; Try a different outlet |
| No sound during playback | Audio cables incorrectly connected; Amplifier input not selected; Tape heads dirty | Check RCA cable connections; Select correct input on amplifier; Clean tape heads |
| Poor sound quality (dull, muffled) | Dirty tape heads; Magnetized tape heads; Worn tape | Clean tape heads; Demagnetize tape heads; Try a different tape |
| Tape speed fluctuates | Dirty pinch rollers/capstans; Worn drive belts (internal) | Clean pinch rollers/capstans; Contact service personnel for belt replacement |
