Teac A-7300RX 2-Track Master Recorder Reel to Reel

TEAC A-7300RX 2-Track Master Recorder

The Teac A-7300RX tape deck is designed for the serious professional or demanding audio enthusiast who not only wants to record live musical performances, but also aims to create high-quality recordings from a variety of audio sources such as turntables, network players, CD players, and other line-level equipment.

It is one of the first tape decks in the world to feature the dbx Type-I noise reduction system, enabling an exceptional dynamic range exceeding 100 dB while minimizing tape hiss. This makes it ideally suited for capturing both live and studio-quality sound with outstanding fidelity.

Thanks to the combination of the dbx system, built-in mixing capabilities, versatile input options (including multiple microphone and line inputs), and precision engineering, this recorder stands as a testament to TEAC’s core philosophy: delivering reliable, high-end recording instruments that meet the exacting demands of musicians, audiophiles, and professionals around the world.

Mechanics and Tape Transport:

To ensure very stable and precise tape movement, high-quality mechanical components are used:

• A precision die-cast aluminum chassis guarantees durability and dimensional stability.

• Dynamically balanced impedance rollers reduce flutter and uneven tape travel.

• An oil-damped tension arm ensures constant tension, smooth starts, and prevents audio skipping.

• Short distances between the heads and capstan minimize modulation distortion.

• The tape is guided with constant angle and tension for accurate playback.

• The DC servo motor operates without mechanical contact, making it silent, low-maintenance, and electronically controlled for constant speed.

• The entire mechanism is driven by a logic-based IC circuit (no relays or mechanical switches), ensuring reliability and smooth, direct operation – including instant playback from fast-forward or recording during playback.

Sound Quality and Recording Functionality:

The recorder offers extensive recording capabilities:

• Four microphone inputs (two per channel), allowing stereo mix recordings with multiple microphones.

• Two line inputs per channel, for mixing multiple line-level sources.

• Microphone and line inputs can also be mixed simultaneously.

• The microphone amplifier features a high 45V supply, direct-coupled PNP/NPN transistor design, and a wide dynamic range.

• Each channel includes a 20 dB microphone attenuator to prevent clipping from loud signals.

• The record master volume allows for simultaneous adjustment of all input levels.

• A memory marker on the input volume knob enables quick return to a preset position.

Monitoring, Editing, and Operation:

• Equipped with a precise peak level meter (-40 dB to +5 dB) with a 10 ms response time to capture fast transients.

• Cue and edit functions allow you to manually locate track beginnings or exact edit points.

• A hinged/openable head housing facilitates editing and maintenance.

• Pitch control allows tape speed adjustment within ±5%.

• The linear counter displays elapsed time in minutes and seconds, accurate to within ±1.5%.

• Real-time pause, memory auto-stop, and timer-controlled recording/playback (with optional timer) are also available.

Additional Features:

• A 4-track playback head for compatibility with standard stereo recordings.

• dbx-encoded output and decode/copy function for noise-free dubbing.

• MPX filter to suppress pilot tones during FM radio recordings.

• A 3-position tape selector, with independent settings for bias and equalization.

• Output volume with click-stop at reference level for accurate alignment with external equipment.

A full-function remote control RC-170 was available as an optional accessory.
