for Details on the series 40

the units of The 40 series are designed for faster and more versatile production:

Manual, Damp and Stop the editing capabilities for quick and convenient Editing (42B-dB)
2 independent controls for input Level and output Level per channel. (42B-dB)
Monitor tracks or inputs as they are needed, using individual pre-load and recording selector switches plus output selector switches.
XLR sockets for inputs and outputs 600 ohm balanced.
Synchronous recording option. The 42 2-track machine can be used for 1-track overdubs.
Speedometer-controlled digital display with positive or negative real-time display.
An auto-loader controls a "searchto-cue" in both directions during fast rewinding.
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 and stops the tape at "00:00".
Speed adjustment: for +/-12%
Cue possibility with one hand.
Rear SMPTE connection option (accessory) carries TTL level and is compatible with the devices of Adam Smith, Audio Kinetics, BTX, Convergence, EECO, HD, TV, United Media and other well-known brands.
Retrofittable dbx noise reduction, dx4d, dx2d
The devices of the 40 series also include cutting-edge technology in electronics:
All amplifier stages are directly coupled in order to be able to achieve the lowest distortions and optimal frequency response even for very low frequencies.
The input amplifiers for the sync and playback heads contain extremely low-noise differential FET's for better pulse and phase behavior.
Eight different supply voltages including bipolar 15V for all audio levels offer optimal reliability.
VU-Meter plus peak LEDs allow a fast and accurate display of short high modulation peaks.
