4 - The PatchMix DSP Mixer Main Section Auxiliary Effects & Returns The section immediately below the TV Screen is where you assign the Auxiliary Effects. In a traditional mixing console, auxiliary effects sends are used to send part of the signal to outboard effect devices, then return the effected signal back into the mix using the effect returns. This is called a sidechain routing because the aux signal takes a detour through the effects before being summed back into the main mix. Sidechain effects are usually effects that you might want applied to several channels, such as reverb. Effects such as EQ and compressors are usually NOT used as sidechain effects because they can cause unpredictable results when returned to the main bus. The Wet/Dry mix setting in the effect should normally be set to 100% when the effect is inserted as a sidechain effect. This is because the Aux Return Amount will control the wet/dry mix.

By turning the Aux Return amount all the way down and dropping an Insert Send into the chain, you can send the Auxiliary bus to any output you wish. See "Insert Section" for more information., Sync/Sample Rate Indicators The Sync/Sample rate Indicators show the current session's sample rate and whether it is internal or slaving to an external source. The display indicates which sample rate is currently in effect. If an external source is being used, the Source display reads "EXTERNAL." When slaving to an external master source, the clock may drift slightly or change dramatically (i.e. abrupt sample rate change or unplugging of physical master source). PatchMix DSP is tolerant to minor drifting within the supported rates of 44.1k, 48k, 88.2k, 96k, 176.4k and 192k, but if the sample rate drifts out of this range the "LOCKED" LED will extinguish. If the external clock source makes a radical sample rate change from the lower rates of 44.1k/48k to a higher rate or between any of the higher rates, the hardware automatically switches to internal 48kHz clock until the proper external clock is restored. The "LOCKED" LED will be off and the two units are NOT synchronized. Always check the "LOCKED" LED when using an external clock source to make sure you are samplelocked.
