Review DOLBY Rare Original 1960s Type Noise Reduction Stretch Unit

Introducing the Dolby A301 1960s Noise Reduction Stretch Unit, a rare and intriguing piece of audio technology with a rich history. This unit was originally designed and manufactured by Dolby Laboratories in the 1960s, a time when the film industry was making the transition from mono to stereo sound. The A301 was a crucial component in the process of improving the overall audio quality of films during this period.

The Dolby A301 is a noise reduction stretch unit, which means it was specifically engineered to reduce unwanted background noise and expand the dynamic range of audio recordings. It achieved this through a process called "variable compression," which adjusts the compression ratio based on the loudness of the audio signal. This allows quieter sounds to be heard more clearly while maintaining the integrity of the louder sounds.

The unit's design is as impressive as its functionality. The Dolby A301 features a sleek, compact chassis with a silver finish and a series of knobs and switches that allow for precise adjustments to various parameters. These controls include:

1. Level control: This knob sets the overall gain level of the input signal.

2. Noise reduction control: This knob adjusts the amount of noise reduction applied to the signal.

3. Stretch control: This knob determines the degree of audio expansion, allowing for more dynamic range.

4. High-frequency boost: This switch adds a boost to the high-frequency range to compensate for the noise reduction process.

5. Bypass switch: This switch disengages the noise reduction process for comparison purposes.

The Dolby A301 also comes equipped with a pair of XLR inputs and outputs, allowing for easy integration into any audio system. Its sturdy construction, combined with its unique and iconic design, makes it a valuable addition to any audio enthusiast's collection.

In summary, the Dolby A301 1960s Noise Reduction Stretch Unit is an essential piece of audio technology history. Its ability to reduce noise and expand the dynamic range of audio recordings revolutionized the film industry and continues to capture the interest of audiophiles today. With its distinctive design and precise control features, this unit is more than just a piece of equipment; it's a testament to the passion and innovation that drove the early days of audio engineering.

Details:

This gave a sort of high-end sheen. Power Cord NOT Included. This is an original A301 2-channel unit built in London during the late 1960s with a complete discrete signal path. We brought the output of vocal back to another fade and summed compressed signal with Dolby about 60/40 a track.

From a Mix Magazine Interview: Cain still remembers one of the effects that was employed on Perry's vocal, trick he learned from producer Keith Olsen: We had an old 2-track Dolby processor, which we pulled cards seven and three out. We printed it that way. These units are famously used for the Dolby A Trick otherwise known as Stretch Mods which have earned a reputation achieving an air effect of lead vocals Like Journeys don't Stop Believing Engineers during 1970s and 1980301 vocal compressor/expanded, bass guitar compressor, etc. Risky stuff but it became Steve Perry's sound.

The unit will need to be restored and recapped by a qualified technician.
