Presonus Audio electronic ACP88 user manual Stereo Compressing/Limiting

BASIC SETUP & APPLIC ATIONS

such as 2kHz to 8kHz, the Compressor will apply the Gain reduction more to the sibilance because it is now 'seeing' more signal around the frequency of the sibilance. You will need to adjust the frequency of the equalizer to locate your source of sibilance more precisely. Parametric equalizers are most effective for this type of compression but you can get by with most any equalizer.

Stereo Compressing/Limiting.

The Linking feature of your ACP-88 will allow you to have up to four stereo Linked pairs of Compressor/Gates. As you may have read in the section in Chapter Two on the Link function, this is easily achieved by pushing in the Link button on the right-hand channel thus creating a Linked Stereo Pair. The channel on the left becomes the Master for the Linked stereo pair and all functions on the Right channel (with the exception of the Bypass switch) become inoperative. Meters on the right channel will behave as before but have no significance since the Gain reduction for this channel is being derived from the Left channel.

To avoid confusion, it might be useful to turn the Compression Ratio to 1:1 on the channel with the Link button pushed in (the right channel). This will eliminate all Gain reduction and effectively turn off the Gain reduction meters. The Gain reduction is of course being derived from the Master channel.

The Link LED indicates when a signal is being passed from the Linked channel to the Master channel. It will ONLY light up when signal is applied to the Linked channel.
