MAKING CONNECTIONS
As with all audio equipment, ensure system levels are turned off before making any connections. This will help avoid turn-on or plug-in
transients that could damage more sensitive components such as tweeters. There is no power switch on the SW8. As soon as you connect
the power supply, it will turn on and one of the LED’s below the AB select switch will illuminate to let you know power is on. To prevent
accidental disconnect, there is a cable lock next to the power input jack that is used to loop-through the power cable.
Connect your two playback machines to the SW8 inputs and send the output to your monitor system using the rear panel D-Sub. Before
you hit play... set the SW8 in ‘start-up mode’ as follows:

Always test at a low volume as this will reduce possible damage due to improper connections. Turn on both playback systems and try
switching between inputs A and B by depressing the front panel AB select switch.
If all is well, connect the XLR-male outputs from the front panel to your main PA mixer. These outputs are isolated to help eliminate the hum
and buzz that often fi nd their way into audio systems. If you encounter noise, try lifting the ground by depressing the lift switch adjacent
to each output. In the event that you hear distortion, check to make sure your signal levels are not overloading the input on your console
by adjusting the preamp trim. If the problem persists, simply depress the global PAD on the SW8 and the input sensitivity going to the
transformer isolated XLR outputs will be reduced by -20dB. The PAD switch is recessed to prevent being accidentally depressed during a
live show.

Front panel XLR outputs feed the main PA system.
Using the mute switch
The SW8 is equipped with a mute function that turns off the XLR outputs on the front
panel. This innovative feature enables the playback technician to mute the outputs going
to the PA while leaving the D-Sub output unaffected. This lets you cue up tracks or make
level adjustments ‘on the fl y’ without disturbing what may be happening in the main PA
system.
To use the mute function, depress the MUTE switch on the front panel. An LED indicator
illuminates when the function is active to alert you the XLR outputs are muted. Depress
the MUTE switch again to turn the function off and restore playback through the XLR
outputs.
