The Studer A820 Multitrack Recorder is a professional analogue tape machine designed to combine advanced electronic control with precision mechanical engineering. Developed as part of Studer’s continued evolution of multitrack recording systems, the Studer A820 Multitrack Recorder integrates modular construction, processor-controlled operation, and extensive configuration flexibility to meet the requirements of high-end studio environments.
The Studer A820 Multitrack Recorder was engineered around a highly refined tape transport system, designed for stability, precision, and long-term reliability. The transport incorporates a rigid mechanical structure with precision components manufactured to tight tolerances, ensuring accurate tape handling and consistent performance across a range of operating conditions. The machine supports reels up to 356 mm in diameter and is designed for both horizontal and vertical operation, with configurable console mounting options.
A key aspect of the Studer A820 Multitrack Recorder is its processor-controlled architecture. A multiprocessor system manages both transport and audio functions, allowing programmable operation, automated calibration, and flexible configuration of machine parameters. This system enables precise control over tape motion, braking, and tension, as well as integration with synchronisation and control systems.
The Studer A820 Multitrack Recorder features programmable transport behaviour, including adjustable shuttle and cue functions, as well as programmable winding speeds. The capstan drive system is designed for low vibration and stable tape speed, supporting multiple selectable tape speeds and ensuring accurate playback and recording performance. Automatic tape tension control and braking systems contribute to consistent tape handling and reduced mechanical stress.
Audio performance is supported by modular electronics, with plug-in audio cards providing ease of maintenance and configuration. The machine supports multiple track formats and head configurations, including full-track, stereo, and multi-track variants. Equalisation standards such as NAB and CCIR are supported, with selectable time constants and calibration options.
The Studer A820 Multitrack Recorder includes integrated timecode capability with SMPTE/EBU compatibility, supporting multiple frame rates and synchronisation with external systems. A dedicated timecode channel allows simultaneous recording and playback of timecode alongside audio, with adjustable delay compensation to maintain alignment between code and audio tracks.
Operational flexibility is further enhanced by programmable control panels, digital displays, and memory functions that allow storage and recall of machine settings. The system supports remote control interfaces, serial communication, and integration with external synchronisers and automation systems.
The Studer A820 Multitrack Recorder was introduced in the late 1980s as part of Studer’s professional analogue recorder range.
