Setting Up and Using the MPL 1640
l. The gain structure is now correctly set—you’ve optimized the level of all sig-
nals coming into and out of the MPL 1640, and the end result will be mini-
mum noise and distortion and maximum clean sound. You’ll now find that
the majority of your mixes can be accomplished with most channel faders
and both Main L/R faders at or near their 0 (unity gain) position and that the
channel peak LEDs rarely if ever light (remember, if they do light, it means
that something is distorting!). If you need to make adjustments to the over-
all level, use the volume control of your power amplifier.
Because this procedure sets the optimum input gain of all channels, it also
sets the correct gain structure when using the MPL 1640’s alternative Bus
3/4 outputs. Following this procedure, if you opt to route a channel’s signal
to the Bus 3/4 outputs (by pressing in that channel’s Bus switch), simply set
the main Bus 3/4 level knob to its detented 0 (unity gain) position for best
signal-to-noise ratio.
If you encounter difficulty with any aspect of setting up or using your MPL 1640,
you can call Samson Technical Support (516-932-1062) between 9 AM and
