in the low octaves and can cause excessive compression. Our ears may tend to associate loudness with

mids or high mids for some sounds and one may be wanting the compressor to regulate and smooth

perceived loudness. Removing some amount of low frequencies that the compressor “sees” can help

especially if one is compressing deeply (-8 dB or more)

Link

When link buss is provided by the 500 series rack, install modules and use switch to link. Note that

other devices using the link buss cannot be installed at the same rack at the same time.

When link buss is not provided (i.e. API rack), a jumper wire must be used to connect adjacent or

multiple modules. We have provided a 2 pin connector on back for a jumper cable to link modules.

Both pins carry the link signal so that single wire jumpers can be used to link multiple modules in daisy

chain fashion. Cables may be aquired through your local dealer at the time of purchase.
