6.0 Link Section

The LINK section of the 2500+ controls the amount each channel will influence the gain reduction of
the opposite channel.
reduction on each channel to be reduced or eliminated.
Most stereo compressors only allow 100% linking between channels. The 2500+ allows for linking to
start at IND (independent), where each channel operates as a separate compressor with 0% influence
between channels. 50% to 100% in six additional steps can be applied the amount of linkage between
channels. 100% will yield equal gain on both channels. At the same time, each channel is still controlled
by its own detector, preventing loading and slaving from one side, which many times creates errors.
In addition, the 2500+ allows the response speed of the Left/Right control voltage link to be filtered
so the link acts on peak information (FAST) or RMS information (SLOW). If both are selected, both
peak and RMS information is attenuated in the control voltage link, resulting in very subtle linkage.
In combination, the 2500+ offers very accurate compression while providing the flexible and precise
control needed to achieve exacting results in any application.

L/R LINK: Sets the percentage of the control voltage link between the Left
and Right channels
• IND (independent): No linkage between channels; channels
operate independently of each other with no influence from the
opposite channel
• Percent: 50, 60, 70, 80, 90, and 100% fixed steps
