12. POWER AMP MODE SWITCH
This two-position switch
lets you choose which signal
paths from the mixer section
are sent to the internal power
amplifi ers. It only affects the
speaker-level outputs (3).
Stereo Mains
In the upper switch position, the output
from channel A is the left side of the
main mix, and the output from channel
B is the right side of the main mix.
Choose this position to play a stereo
show.
Mains/Monitor
In the lower switch position, channel A
is the main mix (in mono), and channel
B is the monitor mix. In this setup, you
could run a mono PA system on channel
A, and a passive stage monitor system
on channel B.
13. POWER AMP INPUTS
These 1/4" TS unbalanced inputs allow you
to connect line-level signals directly to the
input of the internal power amplifi ers.
The internal amplifi ers will then only play
the audio that enters here from the outside
world. The master level (28), graphic EQ
(25), and amp mode switch [12] will have
no effect, and the meters (26) will not show
the levels. Only the series 69 EQ switch [33]
will affect the output. Plugging anything into
these inputs does not affect the line-level
outputs.
You could patch a device between the
main outputs [11] and these inputs, in which
case, the controls and meters will work,
except for the amp mode switch.
These inputs are also useful when you
need more channels than the powered
mixer provides. You could connect the line-
level outputs from an external mixer, and
use this external mixer to control the mix
and levels playing in loudspeakers attached
to the powered mixer. You could also
connect the main line-level outputs (11) to
the external mixer to merge the powered
mixer’s channels and the external mixer’s,
for even more channels.
The external mixer or device will
control the volume, so turn it down
at fi rst, or the powered mixer may
come on at full volume.
