Studer A816

The Studer A816 is a professional analog reel-to-reel tape recorder introduced in the mid-1980s as part of Studer’s high-end lineup, including models like the A810, A812, and A820. It incorporates advances in microprocessor-controlled transport mechanisms and sophisticated audio electronics, making it ideal for mastering and broadcast applications.

Technical Overview of the Studer A816:

Tape Transport & Formats:

• Tape Speed Options: 30, 15, 7.5 inches per second (ips).

• Tape Width: 1/4 inch (6.35 mm), 2-track stereo format.

• Tape Reel Capacity: Standard 12.5-inch metal reels.

• Tape Transport: Servo-controlled with precision DC brushless capstan motor.

• Spool motors and pinch roller motor are electronically controlled for stable tape handling.

• Tape tension controlled electronically and mechanically for consistent tape travel.

• Fully modular transport for ease of maintenance and headblock interchangeability.

Audio Electronics:

• Integrated advanced phase correction circuits in record and playback amplifiers.

• Equalization switchable between NAB and CCIR standards.

• Signal-to-Noise Ratio: Typically around 74 dB at 15 ips.

• Frequency Response: Extended bandwidth from approximately 20 Hz up to 22 kHz at 30 ips.

• Wow and Flutter: Very low wow & flutter spec, about 0.015% at 15 ips and 0.010% at 30 ips.

• Amplifiers are modular and accessible, enabling quick servicing and calibration.

• Controls for stereo/mono operation and tape type tuning.

Controls & Features:

• Digital microprocessor-based control and diagnostics, allowing storage of calibration parameter sets.

• Electronic transport control with programmable function keys.

• Display includes hexadecimal parameters for precise setup and diagnostics.

• Optional time code recording versions and audio safety/ready switches.

• Tape scissors and tape marker integrated on the headblock assembly.

• Library wind and slow spool functions minimize tape wear.

• Supports horizontal, vertical, or inclined mounting.

Physical Characteristics:

• Dimensions (HxWxD): Approximately 900 × 630 × 660 mm.

• Power Consumption: About 90 W in stop, 150 W during play/record, 190 W during rewind/fast forward.

• Voltage selection: 100 to 240 V AC, 50–60 Hz.

• Weight: Generally around 50 kg (depends on configuration).

The Studer A816 combines the mechanical groundwork of earlier models like the A810 and A812 with refined microprocessor control systems for transport and audio. It is widely praised for its audio quality, reliability, and ease of maintenance in professional mastering, broadcast, and archival environments
