DSP Requirements for TDM <strong>Plug</strong>-<strong>Ins</strong><br />

The tables on the following pages show the total<br />

number of instances of each <strong>DigiRack</strong> TDM<br />

plug-in that can be powered by a single DSP<br />

chip on the Pro Tools 24 MIX card and the DSP<br />

Farm. DSP usage differs according to card type.<br />

Though there are a total of 6 DSP chips on a<br />

Pro Tools 24 MIX card, certain plug-ins, such as<br />

the Mod Delays, require a specific type of DSP<br />

chip to function. The tables indicate the number<br />

of compatible chips per card for each plugin.<br />

<strong>Plug</strong>-ins used in multi-mono format on greaterthan-stereo<br />

tracks require one mono instance<br />

per channel of the multi-channel audio format.<br />

A multi-mono EQ used on a Dolby <strong>5.1</strong> format<br />

track, for example, requires six mono instances<br />

since there are six audio channels in the Dolby<br />

<strong>5.1</strong> format.<br />

Because multi-channel versions of the Compressor<br />

II, Limiter II, and Expander Gate II plug-ins<br />

are available for use on greater-than-stereo<br />

tracks, separate instance counts are given for<br />

those configurations.<br />

The tables that follow show theoretical<br />

maximum performance when no other<br />

plug-ins are sharing available DSP resources.<br />

You will typically use more than<br />

one type of plug-in simultaneously.<br />
