Studer B30

The Studer B30 is a professional monaural tube reel-to-reel tape recorder introduced in 1957. It was one of Studer’s earliest portable tape recorders, designed primarily for mobile use and location recording.

Technical Overview of Studer B30:

Tape Transport & Mechanics:

• Tape Format: Mono (single track) on 1/4 inch tape.

• Tape Speeds: Supports up to 4 tape speeds ranging from 3.75 ips (9.5 cm/s) to 30 ips (76 cm/s).

• Tape Handling: Designed for portable and mobile use with robust mechanical design for reliability in field conditions.

• Reel Size: Compatible with standard reels suitable for professional tape recording.

Electronics:

• Amplification: Vacuum tube (valve) based electronics providing the warm analog sound characteristic of the era.

• Equalization: Standard NAB equalization adapted for professional applications.

• Power Supply: Switchable AC line voltage supporting 100, 120, 140, 200, 220, or 240 volts.

Portability and Use:

• Introduced as Studer’s first portable tape deck, making it popular for outside broadcasts and location sound recording.

• Built to withstand mobile operation demands with solid construction and simple controls.

• Often used by broadcasters and professional recordists before the widespread adoption of transistorized and solid-state devices.

Historical Importance:

• The B30 was released four years before the iconic Studer C37 tube tape machine.

• It represents one of the earliest steps in incorporating high-quality reel-to-reel tape recorders in mobile applications.

• The tube electronics of the B30 contributed to the classic analog sound favored in professional recordings of the 1950s.

The Studer B30 is notable for its portability combined with professional-grade tube circuitry, making it a valuable machine for high fidelity field recordings and an important part of Studer’s historical lineup
