Ampex PR 260

The Ampex PR-260 is a professional reel-to-reel tape duplicator system designed for high-speed commercial tape duplication, not a conventional consumer tape deck.

Key Technical Overview:

• Duplication Speeds: Supports 3¾, 7½, and 15 inches per second (ips) duplication, with masters running at standard audio speeds and duplicates produced at much higher speeds.

• Tape Capacity: Can handle reel sizes up to 14 inches, with tape lengths up to 4800 feet.

• Duplication Formats: Full track, half track, simultaneous double half-track duplicates, and two-track stereophonic duplicates.

• Frequency Response: ±2 dB from 50 Hz to 7.5 kHz at 3¾ ips duplicates; up to 15 kHz at 7½ ips duplicates.

• Signal-to-Noise Ratio: Greater than 55 dB for 7½ ips duplicates.

• Wow and Flutter: Less than 0.2% root mean square (RMS) measured at frequencies up to 300 Hz at any duplicating speed.

• Control System: Master playback unit controls multiple duplicating recorders (up to 10), with individual metering and adjustments for each.

• Amplification: Two high-power channel amplifiers feeding multiple slave recorders with minimal level variation.

• Physical Size and Weight: Large console standing about 36½ inches tall, requiring substantial floor space; components weigh between 260 to 335 lbs depending on configuration.

• Power Requirements: 115 V AC, 50 or 60 Hz, with typical current requirements around 12-14 amps for master and one slave.

Usage Notes:

• This system was employed in broadcast and commercial replication contexts for large-scale tape production.

• Designed for efficiency and audio fidelity at high duplication speeds.

• Features modular design for expansion as duplication needs grow.

The Ampex PR-260 represents a professional high-speed tape duplicating system, engineered for broadcast and commercial tape production environments where volume and quality are paramount. It offers flexibility in tape formats, speeds, and duplication methods, backed by a robust control and amplification system that supports up to ten simultaneous duplicating units.

This system embodies the industrial strength and high-fidelity demands of mid-20th-century tape replication technology.
