Analog open-reel tape Recording The Masters LPR35 1/4" (7.62 mm) — 3608 ft reel

Recording The Masters LPR35 1/4" (7.62 mm) — 3608 ft reel is an analog open-reel tape supplied on a single reel, intended for professional audio recording and playback on compatible reel-to-reel machines. The tape uses the LPR35 formulation, a standard choice for balanced frequency response and reliable dynamic range on 1/4" tracks. With a long 3608 ft length, the reel supports extended recording sessions and archival transfers without frequent reel changes.

Advantages

The tape provides stable transport and consistent magnetic properties suitable for studio transfers, mastering tasks, and long-duration live or field recordings. Its LPR35 formulation is known for providing a neutral tonal balance and predictable bias requirements, making it compatible with a broad range of recorders. The long single-reel format reduces interruptions during lengthy sessions and is appropriate for professional studios and archival facilities.

Suitable for

• Studio multitrack transfers and single-track mastering
• Archival audio preservation and tape-to-digital transfers
• Long-duration live recording or continuous monitoring
• Compatibility testing and tape machine maintenance

Key specifications

• Tape width: 1/4" (7.62 mm)
• Tape length: 3608 ft
• Formulation: LPR35 (standard ferric-type formulation for balanced performance)
• Reel format: single open-reel compatible with standard 1/4" reel-to-reel machines
• Intended use: professional recording, mastering, transfers, archival storage

How to use

Load the tape onto a compatible reel-to-reel machine following the machine manufacturer’s threading and tensioning guidelines. Set recorder bias, equalization, and speed according to the LPR35 specification and the target tape speed for your project; common operating speeds for 1/4" tape include 7.5 and 15 ips depending on the desired fidelity and recording duration. Perform a calibration or test recording to verify azimuth alignment, bias level, and head operating conditions before critical recording or transfer sessions.

Usage recommendations

Store the reel in a cool, dry environment away from magnetic fields and extremes of temperature and humidity. Handle tape by the reel flanges and avoid touching the tape surface. Use proper demagnetization (degaussing) and head cleaning procedures on playback and recording machines to maintain consistent audio quality and prolong tape and machine life.
