Using Aux Sends and Returns
The MPL 1502s two Auxiliary sends allow you to combine the signal from
multiple channels and send the resulting mix to external devices such as effects
processors. When an Aux send knob is at the 0 position, the signal is routed
with unity gain (that is, no boost or attenuation). As it is turned clockwise from
the 0 position, the signal is boosted; as it is turned counterclockwise from the 0
position, it is attenuated. Both Aux sends are
post-fade; that is, the level of the
signal is determined by the input trim, the EQ settings, and the position of the
channel gain control. In other words, raising or lowering the input level of the
channel will affect the send level as well.
The MPL 1502 also provides two stereo Auxiliary returns. These allow you to
return signal from outboard devices, either in stereo pairs or monophonically
(many popular effects processors provide a single mono input but have two
stereo outputs). In practice, youll probably want to use the Auxiliary returns to
bring in signal from connected effects processors. If the effects processors have
stereo outputs, they should be connected to both the left and right Auxiliary
return inputs so that their stereo integrity is retained. If they have mono outputs,
you can route them to either the left or right inputs and then use the Auxiliary
return Balance control to adjust the relative level of each paired signal. In this
way, you can actually connect up to four monophonic devices to the MPL 1502s
Aux return section.
Each of the stereo Auxiliary returns is somewhat similar to a stereo channel,
except that a signal being brought into to a stereo channel can be equalized if
necessary and optionally sent on to other outboard devices (via Aux sends or
channel inserts).
