6.0 Link Section
The LINK section of the 50
th
Anniversary 2500 controls the amount each channel will influence the
gain reduction of the opposite channel. This allows “center-image shifting” caused by differing
amounts of gain reduction on each channel to be reduced or eliminated.
Most stereo compressors only allow 100% linking between channels. The 50
th
Anniversary 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 50
th
Anniversary 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 50
th
Anniversary 2500 offers very accurate compression while providing the
flexible and precise control needed to achieve exacting results in any application.
