1981 Teac X-1000R / dbx
back to galleryspecifications

The X-1000R dbx was a high quality, three motor, quarter-track stereo tape deck.

Several variants were produced with the following suffixes:

R (bi-directional record/playback)
dbx (DBX-I noise reduction system)

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:

  • Pitch Control
  • Tape Lifter
  • Dupli-Sync
  • Illuminated VU meters
  • Auto Spacer
  • Auto Timer

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.
