I wanted a Teac AD-RW900 buy in order to digitize my oodles of chrome cassettes with wonderful photographs from the eighties and nineties, or even play it back to me already after my previous cover has (JVC-UX1) given up the ghost. Then I could burn the cassettes to audio CDs or make overdubs on a USB stick. Fortunately, I've been doing online in the manuals. The Teac AD-RW900 has significantly worse data in the frequency response, it is recommended that you do not play a C90 cartridge, normal blank CDs are not to be used, but only the expensive audio blanks, and the MP3 files to work with indisputable compression. In contrast, the 890 Dolby HX-Pro, better frequency response, and otherwise all the amenities you expect from earlier: Auto Stop, all cartridge locations playable, good signal to noise ratio and good frequency response. You can digitize with any ordinary PC or laptop, with the Audio Recorder or Audacity. With VLC you can select file formats and select the degree of compression. So I stopped the appointment of the RW 900 and ordered the W-890-R. This is the better way. A decent analog device, the rest for the PC. One need only a commercially available adapter from RCA to small stereo plug. The Teac W-890-B sounds good, has a robust mechanics, it is possible with both decks in succession 2 times 90 minutes listening to music. It has a sophisticated analog recording technology from one deck to another, a speed control, you can add a microphone mix and adjust the MIC volume. I'll hardly use because you can halt with PC (VLC) perfect to take digital. But to play my rich collection cassette, the device is ideal. Well, some prefer to buy a second-hand high-end equipment for little money. I have no desire to fuss around me in a short time with worn-out drive belt. Thank Teac that there is this new device.
