Using the AUX SEND jacks
When the AUX SEND jacks of the MD4S are used, a single external effect processor can be used
simultaneously by two or more input channels. For example when you are re-recording several
channels to two tracks or when mixing down, you can use this method to apply an effect such as
delay or reverb while adjusting the depth of the effect independently for each channel (track).
When using the AUX SEND jacks to connect an external effect processor, connect the AUX
SEND jacks 1 or 2 to the input jacks of the external effect processor, and connect the output
jacks of the effect processor to LINE INPUT jacks 5 and 6 or 7 and 8.
External effect connections when using the AUX SEND jacks
With this setup, rotating the AUX controls of the input channels toward the 1 or 2 position
will mix the signals from the input channels (in mono) and send them via the AUX SEND 1 or
2 jack to the external effect processor. The output signals from the effect processor will be
mixed via the LINE INPUT jacks 5 and 6 (or 7 and 8) into the ST bus. Normally, the technique
of using the AUX SEND jacks to apply effects is used for effects in which the original sound is
mixed with the processed sound (e.g., delay, reverb, chorus etc.). In general, you should make
settings on the effect processor so that it will output only the processed sound, and use the
MD4S mixer to adjust the mix of the original sound (the signal sent from the input channel to
the ST bus) and the effect sound (the signal sent via LINE INPUT jacks 5–8 to the ST bus).
