200/500 Series
Letter from the President

Dear Audio Professional,

API has a history rooted in the 1960s — the decade when the search for preserving audio quality was at its most frantic. The now-legendary recordings that were made during the '60s and '70s live on today as historic landmarks for the music industry. I am proud to say that API was an integral part of that past and is proud to carry on that tradition.

Today API is both pleased and gratified to continue to play a major role in the recording and production of music. As we enter our fifth decade of manufacturing the best audio gear we can, API stands ready to deliver that same warm analog "magic" that we have been known for since the 1960s.

I was thrilled with the opportunity to acquire API more than 10 years ago, and I am just as thrilled today, as it remains an exciting time to be producing such extraordinary audio equipment. The "standard" API products like the 512c Mic Preamp, 525 Compressor and the 550b EQs continue to win listening tests, technology awards, and new fans, while the "newer" products such as the 2500 Bus Compressor, the A2D Mic Pre, the 527 Compressor and the phenomenally successful 1608 console demonstrate just why API gear is involved in so many of today's top recorded projects – everything from slammin' demos to chart-topping hits.

With our long-standing tradition of providing a no hassle, 5-year parts warranty on every product we make, the demand for API continues to increase. I invite you to make an investment in the API tradition, and in turn, I would like to welcome you to the 'API club' of enthusiastic and dedicated Audio Professionals.

Best regards,
Larry Droppa

An Abbreviated History of API

In 1968, Automated Processes, Inc. was formed by engineers and music professionals with a vision. Today API is well known for many contributions to the field as well as a long-standing trademark warm sound. The 2520 amplifier, a unique amp invented by co-founder Saul Walker has been and will continue to be at the heart of all API discrete products. The 2520 continues to provide reliability and sonic purity unmatched by the competition. The early API consoles met the needs of music, commercial and broadcast industries.

API became the leading audio broadcast console manufacturer for radio and television networks and high profile stations. In addition, recording studios, large and small, began using API.....and receiving rave reviews from engineers and producers. There are over 700 API consoles across the nation and around the world, including the three major networks. Over forty years later, many of these consoles are still in daily use in some of the most prestigious recording and broadcast facilities in the world because, to date, there are few, if any consoles of equal sound quality at such a cost-effective price.
