Manufacturer's Description
Sony has built the deck with high-density Permalloy tape heads for long life. For noise reduction, the TC-WE475 is outfitted with both Dolby B, the encoding standard used on most prerecorded cassettes, and Dolby C, which buys you another 10 to 20 dB or so of noise reduction beyond that offered by Dolby B (around 10 dB). Use Dolby when recording and, if a tape has been recorded using Dolby, when listening.
Two other technologies specifically heighten the quality of your recordings. During loud level peaks, Dolby HX Pro dynamically adjusts the bias signal (a supersonic and basically sacrificial tone your deck uses to push distortion out of the audible range), effectively letting you record "hotter"--that is, louder on tape--without compressing the high-frequencies of your program material. Secondly, an onboard MPX filter blocks the 19 kHz multiplex pilot tone of FM stereo broadcasts for proper Dolby noise-reduction tracking when you record off the air.
Other features include full-logic, feather-touch transport controls and twin electronic tape counters (one for each deck), which come in handy when you're making a compilation from a variety of source tapes. If you have a Sony audio/video receiver, you can operate the deck from your receiver's remote control.
