A810 Tape Recorder

About the A810 Tape Recorder

The Studer A810 is a professional 1/4" reel to reel tape recorder designed for high-end studio, broadcast, and film applications. It features four selectable tape speeds (3.75, 7.5, 15, and 30 ips) with a microprocessor control system that manages operator controls, tape transport, and audio electronics. The machine supports mono, stereo, and four-channel versions and offers balanced floating inputs and outputs with optional transformers. It includes programmable audio parameters stored digitally for each tape speed and tape formulation, eliminating the need for manual trimmer adjustments. The A810 has a highly rigid die-cast aluminum chassis, quartz-controlled capstan motor servo, electronically controlled tape tension, and non-contacting tape tension sensors for gentle tape handling. It also features a built-in monitor speaker, selectable NAB or CCIR equalization, tape bias switch, sync facility, zero locator, and transfer locator. The machine is suitable for horizontal or vertical operation and can be rack-mounted or console-mounted. It is known for excellent frequency response (30 Hz to 20 kHz at 30 ips), signal-to-noise ratio ranging from 50 to 70 dB depending on configuration, and robust mechanical and electronic design. The A810 is highly regarded for its sound quality, reliability, and ease of use with programmable function keys and digital displays. It weighs approximately 30 kg and consumes about 100 W idle and 300 W during recording. The machine is considered a workhorse that can last indefinitely with proper maintenance.
