Mark L MLC - Mix 1 and Mix 2 Detailed Operation; Mix 1 Input and Output Configuration; Mix 2 Input and Output Functions

Mix 1 consists of four pairs of Left and Right
inputs, two External split outputs, and two pairs of MIX 1 outs. All of these jacks are
for mono plugs, and are intended for line level signals.
For mono signals, use only the Left input and the signal will feed into both the Left
and Right channels.
After the four inputs are combined, their overall volume is controlled by the MIX 1
knob on the front panel, and the resulting signal is passed to the two sets of Mix 1 Out
jacks.
Mix 1 In 1 and the External Split
You will blend the outputs of your effects with the pure tone of your preamp. In most
cases, the output of your preamp (or your amp's effect send) will be connected to Mix
1 In 1. The External Split outputs are copies of the signal coming in Mix 1 In 1. These
outputs are used to drive the inputs of your effects devices.
Mix 1 Outputs
There are two separate identical stereo pairs of outputs for Mix 1. Mix 1 is also
internally connected to Mix 2. These outputs can be used to drive the inputs of more
stereo effects devices for a second "stage" of processing. The outputs of these effects
can then be connected to Mix 2 inputs. In this way you can have two stages of parallel
effects, one cascading into another. In Section 6 you will see how it all comes together
in a system.
Mix 2
Mix 2 consists of four pairs of Left and Right inputs, and one pair of MIX 2 outs.
After the four inputs are combined, their overall volume is controlled by the MIX 2
knob on the front panel, and the resulting signal is passed to the Mix 2 Out jacks, and
to the Cabinet Simulator circuitry (which feeds the rear panel Direct Outs and the front
panel Balanced Outs).
Mix 2 In 1
If the Mix 2 In 1 jacks are empty, the stereo output of Mix 1 will be fed into Mix 2.
Inserting a plug into them will break this normal connection between the
two mixers.
Mix 2 Outputs
The Mix 2 Outs carry the sum of all the Mix 2 inputs. This is the output to connect to
your power amp, or to your amp's effect return jacks. If you need an output with the
Cabinet Simulator, then use the Direct or the Balanced Outs instead.
