Additional Information
The Ampex 985 reel-to-reel tape deck is a stereophonic tape recorder introduced in the 1960s, frequently found as part of the Ampex Music Center system. This premium deck was designed for home hi-fi enthusiasts and bundled with a tuner and speakers for a complete audio setup.
Three-Head Design: Offers separate erase, record, and playback heads, supporting tape monitoring and sound-on-sound capabilities for flexible recording and editing.
Tape Monitoring: Enables real-time listening during recording, crucial for precise home recordings and semi-professional use.
Pause Control: Provides enhanced user control during taping sessions, convenient for segmenting recordings.
Frequency Response: Designed for high fidelity, especially at the standard tape speeds (typically 3¾ and 7½ ips) used in home machines of this era.
Inputs/Outputs: Features preamplifier inputs for microphones and line sources, along with speaker outputs tailored to Ampex’s slide-on and bookshelf speaker designs.
Bundling: Commonly sold with two dynamic microphones and slide-on speakers that could be separated up to 20 feet for flexible sound staging.
Physical Build: Walnut finish, sturdy construction, reflecting Ampex’s focus on aesthetics and reliability for domestic interiors.
The Ampex 985 emphasized ease of operation and sound quality, making it popular among home recordists. Its three-head arrangement allowed advanced tape manipulation and monitoring, while its bundled microphones and speakers delivered a comprehensive music system experience. Models like the 985A were direct descendants of Ampex’s pro-audio expertise adapted for high-end consumer use.
In summary, the Ampex 985 is a classic stereo tape deck offering 3-head monitoring, versatile inputs/outputs, a premium build, and system integration—all catering to audiophile-grade home music recording and playback.
