HAIRBALL FET RACK Active link instruction

Passive and active link both have their advantages. The advantages of using active link include:

• unlike passive link, attack times are not doubled when using an active link
• does not require an external adaptor or calibration
• activate linking with the push of a button
• links easily to Purple Audio MC77

To activate linking, set both link PCBs to the ON position and set one unit to SEND and the other to RECEIVE. Start by matching the settings on both units. This includes input, output, attack, release, and ratio.
Once you have the desired compression you may notice that your GR is a little less in one unit due to side-chain tolerance differences. To get the two units tracking the same, you’ll need to adjust the attack on one unit slightly. Typically adjusting the attack on one unit will make tracking worse, and the other will make tracking better.
Now that the units are tracking properly, they may have slightly different output levels. Using your DAW metering or +4/+8 on the FET/RACK units, adjust the output level using the output controls.
