Chapter 1 – Introduction
1.1 Welcome
Thank you for choosing Waves! In order to get the most out of your new Waves plugin, please take a
moment to read this user guide.
To install software and manage your licenses, you need to have a free Waves account. Sign up at
. With a Waves account you can keep track of your products, renew your Waves
Update Plan, participate in bonus programs, and keep up to date with important information.
We suggest that you become familiar with the Waves Support pages: /support. There
are technical articles about installation, troubleshooting, specifications, and more. Plus, you’ll find
company contact information and Waves Support news.

1.2 Product Overview
The API 2500 is a versatile dynamics processor that lets you shape the punch and tone of mixes with
absolute accuracy. Its dual channel design lets the 2500 also function as two separate mono channels
via a single compression setting. Using auto-makeup gain, you can adjust Threshold or Ratio while
automatically maintaining a constant output level. With both Feed Back and Feed Forward compression
types, the API 2500 boasts a wide range of incredibly musical parameters which have made it a favorite
of engineers the world over
.
Waves API 2500 User Manual

1.3 Concepts and Terminology
There are 3 main parameters that set the API 2500 from other compressors: Thrust, Compression
Type, and its adjustable Knee. When used in conjunction with one another, these parameters give the
API 2500 unprecedented flexibility.
Knee
Sets the knee, the manner in which the compressor begins to reduce the gain of the signal.
• In the Hard position, gain reduction begins immediately at the set ratio.
• In the Med position, there is a slight fade-in to the set ratio.
• In the Soft position, there is an even more gradual fade-in to the set ratio.
Waves API 2500 User Manual
- 5 -
Thrust
Sets the Thrust, a proprietary process that inserts a High Pass Filter at the RMS detector input, limiting
compression response to lower frequencies while applying additional compression to higher
frequencies.
• In Norm mode, there is no filter and the 2500 functions like a normal compressor.
• In Med mode, there is a slight attenuation of the low frequencies and a slight boost of the high
frequencies, with a flat mid range affecting the signal into the RMS detector. This reduces
pumping caused by low frequencies and increases the RMS detectors’ sensitivity to higher
frequencies, affecting higher frequency signal peaks.
• In Loud mode, a gradual linear filter attenuates level by 15dB at 20hz and increases level by
15dB at 20khz. This decreases low frequency pumping while increasing higher frequency
compression.
Waves API 2500 User Manual
- 6 -
Type
Sets the Compression type, which determines the signal source being fed to the RMS detector.
• In New (Feed Forward) mode, the compressor works like newer VCA-based compressors. The
RMS detector sends a signal to the VCA that is an exact ratio of the desired compression, set
by the ratio control.
• In Old (Feed Back) mode, the RMS detector receives a signal from the VCA output, and then
feeds the VCA a signal based on the set signal ratio.

1.4 Components
WaveShell technology enables us to split Waves processors into smaller plug-ins, which we call
components. Having a choice of components for a particular processor gives you the flexibility to
choose a configuration suitable for your material.
The API 2500 has two component processors:
API 2500 Stereo – A stereo compressor that may also be used as two parallel mono processors.
API 2500 Mono – A mono compressor with an external sidechain option.
Waves API 2500 User Manual
- 8 -
Chapter 2 – Quick Start Guide
For those of you who are experienced users of audio signal processing tools, we recommend that you
approach the API 2500 as you would any compressor which you are already familiar. Keep in mind that
its Thrust, Compression Type, and Knee parameters offer capabilities that transcend other, more
conventional, processors.
Newer users should explore the API 2500’s preset library and use its presets as starting points for their
own experimentation. These presets also serve as a valuable introduction to compression techniques in
general, and offer a glimpse into the workflow of professional audio engineers.
We encourage all users to experiment with the API 2500’s settings in order to better understand its
unique processing power.

A note about Sidechain:
Sidechain lets you trigger the compressor using an external source, which is fed into the RMS detector
and controls the compression of the input signal. Sidechain may only be used in New (Feed Forward)
mode. An external sidechain trigger cannot be used in Old (Feed Back) mode; attempting to do so
automatically switches the compressor to New (Feed Forward) mode.
3.3 Link Section
L/R Link
Sets the percentage of linkage between the left and right channels
.
While in Link mode, each channel
is still controlled by its own RMS detector, which prevents loading and slaving from either side.
Range
IND, 50%, 60%,70%,80%,90%,100%
Default
100%
Shape
Uses HP and LP filters to adjust the shape of L/R linking. This enables you to remove particularly
high or low frequencies when adjusting the linking. Shape can be used, for example, to prevent
percussive instruments on one channel from coupling and causing unwanted compression on the
other channel. When HP and LP are both selected, a band pass filter is used to determine the
shaping of L/R linking. Click on the Shape button to cycle between the four filter options.
