Direct Drive Capstan Motor: Eliminates belts for the capstan, leading to more accurate and stable tape speed, reduced wow and flutter, and lower mechanical noise.
2-Motor Transport: A dedicated motor for the capstan and another for the reel drive ensure smooth and independent operation of tape movement functions.
SX Head (Sendust Extra): This record/playback head, made of a permalloy and Sendust alloy, was designed for excellent frequency response, low distortion, and good wear resistance, especially with metal tapes.
Metal Tape Compatibility: Capable of recording and playing Type I (Normal), Type II (CrO2), and Type IV (Metal) tapes, offering versatility in tape selection.
Dolby B and dbx Noise Reduction: Incorporates both Dolby B and dbx II noise reduction systems, providing effective reduction of tape hiss and expanding dynamic range for cleaner and more dynamic recordings and playback.
Solenoid Transport Controls with IC Logic: Features light-touch, solenoid-operated transport buttons with an IC logic system. This allows for direct mode changes without having to press "Stop" first, reducing the risk of tape damage.
Output Level Control: Offers a manual output level control for adjusting the playback volume.
Microphone and Line Inputs: Provides both microphone inputs (typically with a 1/4" jack) and line-level inputs (RCA connectors) for versatile recording options.
Line Output: Standard RCA line output connectors for connecting to an amplifier.
Fluorescent Meter: Usually equipped with a clear and responsive fluorescent meter to monitor audio levels during recording and playback.
Timer Recording/Playback: Often includes a timer function for unattended recording or playback when used with an external timer.
Remote Control Capability: Some models supported a wired remote control for added convenience.
