EQ III
The EQ III Plug-In provides a high-quality 
7 Band, 2–4 Band, or 1 Band EQ for adjusting 
the frequency spectrum of audio material.
EQ III is available in the following formats:
•7 Band: TDM, RTAS, AudioSuite
• 2–4 Band: TDM and RTAS only
•1 Band: TDM, RTAS, AudioSuite
EQ III supports all Pro Tools session sample 
rates: 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz, 
48 kHz, and 44.1 kHz. EQ III operates as a mono 
or multi-mono plug-in only. Stereo and multi-
channel tracks are supported through multi-
mono operation. 
EQ III can be operated from the following con-
trol surfaces:
• Digidesign D-Control
• Digidesign ProControl
• Digidesign Control|24
• Digidesign 002
• Digidesign Command|8
• Mackie HUI-compatible controllers
EQ III has a Frequency Graph display that shows 
the response curve for the current EQ settings 
on a two-dimensional graph of frequency and 
gain. The frequency graph display also lets you 
modify frequency, gain and Q settings for indi-
vidual EQ bands by dragging their correspond-
ing points in the graph.
By choosing from the 7 Band, 2–4 Band, or 
1 Band versions of the EQ III plug-in, you can 
use only the number of EQ bands you need for 
each track, conserving DSP capacity on TDM 
systems.
