The API 525 is perhaps the most successful solid state feedback compressor in history. It delivers dynamics control behavior unlike VCA "feed forward" compressors so common today. A remarkable multi-function "ceiling" control can increase gain reduction (lower threshold) while simultaneously raising output level to match, so the user can alter dynamics "on the fly" without level changes. This re-issue design has been taken from the original blue prints and spec control drawings from the API archives.

Release times vary with frequency, with high frequency/full bandwidth content released faster than just low frequency for natural envelope tracking. Attack time is fixed, chosen to catch the fastest peaks, without "pumping". Equally useful as a tracking, mixdown or program compressor/limiter, the benefits of the API 525 are most obvious to those who use compression on a regular basis. "Vintage" dynamics control, an easy to use multi-function control set, and a wide range of 500 Series mounting options assure that the 525 will surpass your most critical applications. With the addition of a hard-wire bypass switch, a balanced input, and a pinout that is the same as all the other 500 series modules, the 525 is still, after 25 years - "the sound". Two or more 525s can be linked for multi-channel compression.

The 525 Feedback Compressor/Limiter makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life, and uniformity which are characteristic of API products.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
