Additional Information

The TEAC A-4300 is a mid-high fidelity, solid-state, 4-track, 2-channel stereo reel-to-reel tape deck produced in Japan between 1973 and 1978. It is designed primarily for consumer use but incorporates features that approach semi-professional quality.


Track and Head System

  • 4-track, 2-channel stereo system (quarter-track format).

  • Four heads: erase, record, and two playback heads allowing bi-directional playback.

  • Heads made of permalloy, known for durability and good magnetic properties.

Tape Transport and Motors

  • Three motors:
    One dual-speed hysteresis synchronous capstan motor for precise tape speed control.
    Two eddy current induction reel motors for stable tape tension and smooth tape winding.

  • Tape speeds: 3¾ and 7½ inches per second (9.5 cm/s and 19 cm/s).

  • Maximum reel size: 7 inches (18 cm).

  • Wow and flutter: 0.06% at 7½ ips, 0.09% at 3¾ ips, ensuring stable playback speed without noticeable pitch variation.

  • Rewind time: approximately 160 seconds for 1800 feet of tape.

Frequency Response and Sound Quality

  • Frequency response:
    At 7½ ips: 40 Hz to 24 kHz ±3 dB
    At 3¾ ips: 40 Hz to 16 kHz ±3 dB

  • Signal-to-noise ratio: approximately 58 dB at full modulation.

  • Harmonic distortion: about 1% at reference level.

  • Channel separation: 50 dB at 1 kHz, with crosstalk around 60 dB at 1 kHz.

  • Sound quality rating: around 6/10, with long-term reliability rated about 7/10.

Inputs and Outputs

  • Inputs: 2 microphone inputs (0.25 mV, 600 Ω or more), 2 line inputs (100 mV, 50 kΩ).

  • Outputs: 2 line outputs (0.3 V, 10 kΩ), 1 headphone output (0.05 V, 8 Ω).

  • Connectors include RCA and DIN types.

Additional Features

  • Single-direction recording with bi-directional playback (no auto-reverse).

  • Index counter repeat function for automatic replay of selected tape sections.

  • Bias and equalization switches for normal or high-output/low-noise tape types.

  • Record lock-out switches to prevent accidental recording.

  • Control guides to mark settings for easy recall.

  • Optional RC-140 remote control available.

  • Solid build with wood side panels and silver/black finish.

Physical Specifications

  • Dimensions: approximately 18 x 19¼ x 8½ inches (457 x 489 x 216 mm).

  • Weight: about 23 kg (50.6 lbs).

  • Power consumption: around 90 W.
