| 1981 Teac X-1000R / dbx | |
 |
The X-1000R dbx was a high quality, three motor, quarter-track stereo tape deck. Several variants were produced with the following suffixes: The R model featured six heads, full auto reverse on both record and playback while the dbx models were equipped with a professional DBX-I noise reduction system. Braking was electrically-assisted, and the tape was handled by a dual capstan drive. A three position tape-type selector gave the user optimum bias and equalisation for normal, LH or EE tape. |
An electronic digital tape counter gave 'real-time' positioning. Other features included:
The unit was available in matt black or silver finish, and either rack-mountable or in a wooden case. Additional images, a full service manual and set of circuit diagrams for this recorder are featured on the CD-ROM. |
