Effects Switcher:
Where effects out-number aux sends or returns
on a live FOH console, the SW4 can help by
being able to switch between effects without
repatching or taking up additional channels. This
is very helpful especially when using vintage gear
where changing effects on a specifi c processor
cannot be done via midi control. The effects
inputs are connected together with 'Y' cables so
one aux line out from the console will connect
two effects inputs. This enables the engineer to
set levels on both effects at the same time. The
outputs can then be connected to input A and B
on the SW4. The output of the channel on the
SW4 can now be connected to one aux or effect
return on the console. With the SW4 PFL bus
and headphones, you can monitor each effect
without switching or routing signal back into the
console and PFL at the console. This is very
handy as a 'preview' monitor before a switch is
made. Using the JR•2 foot switch input, a change
can be automated with a contact closure from a
show control system.
Backing Tracks Switcher:
This application shows the SW4 switching
between a primary and backup DAW multi-track
to provide backing tracks for a live performance.
Should the primary multi-track stop playing, the
technician can switch the SW4 to the backup
DAW. To handle eight tracks of playback a second
SW4 unit is slaved by connecting the JR•2 link
'out' jack from the master SW4 to the JR•2
remote 'in' jack. This allows the master unit to
pass switching and mute commands to the slave.
Both SW4 units are set up so that all channels
switch at the same time and the technician can
trigger the switching using the JR•2DT or the A/B
switch on channel-1. To facilitate monitoring and
cueing of the backing tracks, the mono output
from each SW4 is connected to additional mixing
console channels and the PFL system on the
SW4's is set to monitor the backup multi-track.
The technician can then use their mixing console
to listen to the SW4's PFL system or the DAW
systems to ensure playback is in sync.
