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.
