USING AND TESTING
Bring up the level on the PA system. It is good practice to always test 
at a low volume to ensure proper connections have been made and all 
devices in the signal chain are working. This way, should a device not 
be turned on or a connector not fully pushed in, it will not create a loud 
transient ‘pop’ in the PA which in turn could blow a tweeter or annoy your 
audience. 
Check the status of the two footswitch LED indicators. If the indicator 
labeled ON is not illuminated, depress the footswitch to un-mute and turn 
on the StageDirect’s outputs. If you are using a stage amp, slowly turn up 
the volume and test it as well. 
USING THE -10DB PAD
If you hear distortion, check to make sure the trim control on the PA 
is set correctly. If the problem persists your instrument signal is likely 
overloading the StageDirect input. This can happen when connecting 
high-output electronic instruments like keyboards and bass guitars with 
active pickups. To eliminate the distortion, engage the StageDirect’s PAD 
using the switch on the top panel. When set to the -10dB position, this 
switch reduces the sensitivity of the instrument input which will eliminate 
overload distortion. 
USING THE TUNER OUTPUT
The StageDirect is equipped with a separate output for an electronic 
tuner. The tuner output is not affected by the MUTE footswitch and is 
always on to let you quickly adjust your tuning on the fl y or in silence 
when the MUTE footswitch is engaged. The connection is made using 
a standard hi-Z ¼” instrument cable. For best results, use the shortest 
possible cable to connect your tuner.
