Tech nical data

  • Manufacturer: Teac
  • Model: A- 3300 SX-2T
  • Type: Half-track Tape machine
  • Years of construction: 1976 - 1979
  • Manufactured in: Japan
  • Color: Silver / Black, housing side panels wood
  • Factory price approx.: 2'148 DM
  • The Teac A-3300 SX -2T is the high-speed version of the Teac A-3300 SX , as it has the playback speeds of 19cm/s and 38 cm/s in contrast to the A-3300SX (A- 3300SX 9.5 cm/s and 19 cm/s).
  • The high-speed version was only available as a 2-track version, while the A3300SX was sold as both a quarter-track and a half-track version. By doubling the width of the track and increasing the speed to 38cm / s, there is an improvement in the quiescent noise voltage from 58 dbm to 60 dbm. Often the A3300SX-2T is called a semi-professional machine, since it does not have balanced inputs. Nevertheless, it was often used as a master machine in professional productions (e.g. Gunther Gabriel). Due to its enormous robustness, it was used especially in Japan as a feed machine in cassette copying units. Both the A-3300SX and the high-speed version have microphone preamplifiers and a mixing console for mixing microphone and line signals. Both machines have trimmers for setting all the parameters that are necessary for calibrating the machine. It is possible to set the devices to four different types of tapes and to select the parameters of recording equalization and premagnetization on the front of the device by a switch.
  • As a disadvantage of the machine, it is often said that it is not very high controllable, about 514 nWeber at 38cm/ s. From the factory, the machine is set to 185 nWeber. This is due to the low volt number at which the preamplifiers work (about 22-23 volts).
  • Due to the existence of professional noise suppressors such as Dolby SR or Telcom C4e (improvement up to 30 dbm of the dynamics), this 'shortcoming' is obsolete, since at the same time significantly better values for distortion factor and channel separation result from lower modulation.
  • As the master machine, the A-3300SX-2T is a lightweight (about 22 kg) compared to the Telefunken M10 with 60 kg for the chassis alone. Nevertheless, it is extremely robust and has the best phase stability in stereo operation.
  • The equalization time constants correspond to the NAB standard, i.e., 50 + 3180 micro at 19 cm/s and 38 cm/s.
  • There is a button switch on the front to adapt to different torques for small and large coils.
  • In addition, the machine has switches for individual selection of the 2 tracks left and right as recording tracks.
