Reports

  • Report from "Tape Museum":
  • Series 40 details
  • Series 40 units are designed for faster and more versatile production:
  • Manual, Damp and Stop editing capabilities for fast and convenient editing (42B-dB).
  • 2 independent input and output level controls per channel. (42B-dB)
  • Monitor tracks or inputs as needed using individual pre-load and record selector switches plus output selector switch.
  • XLR jacks for inputs and outputs 600 ohm balanced.
  • Synchronous recording capability. The 42 2-track machine can be used for 1-track overdubs.
  • Tacho controlled digital display with positive or negative real time display.
  • Auto loader controls a "search-to-cue" in both directions during fast rewind.
  • Switching for input and output O-VU at -10dB and + 4dB (42 B-db).
  • A "Return-to-Zero" button acts as a second auto-locator, stopping the tape at "00:00".
  • Speed adjustment: for +/-12%.
  • Cue possibility with one hand.
  • Rear SMPTE connectivity (accessory) carries TTL levels and is compatible with Adam Smith, Audio Kinetics, BTX, Convergence, EECO, HD, Fernseh, United Media and other popular brands.
  • Retrofittable dbx noise reduction, dx4d, dx2d.
  • Series 40 units incorporate leading edge technology in electronics as well:
  • All amplifier stages are directly coupled to achieve lowest distortion and optimal frequency response even for very low frequencies.
  • The input amplifiers for the sync and playback heads incorporate ultra-low noise differential FET's for improved pulse and phase response.
  • Eight different supply voltages including bipolar 15V for all audio stages provide optimum reliability.

VU meter plus peak LED's allow fast and accurate indication of short high output peaks.
