Tuner LED Display
The BASS, MIDDLE, TREBLE controls are a 3-band equalizer for
controlling tone.
The center detent on these tone controls yields a flat tone response.
“+12" boosts the tone; “12"cuts the tone.
The LED will light when the battery has lost power. Replace the
battery when this light is on.
This LED light will flash when a cable is connected to the output
jack of the pickup system. This shows the battery is good.
The PHASE button controls the phase of the pickup in relationship to
the phase of the speaker that are being used with the system.
Pushing this button will put the pickup “out of phase” with the
speaker. When the button is out the pickup is in phase.”
“
This control is most useful for feedback control and will provide a
tone color. Once you experiment with the settings of this control you
will find more about how it works.
The VOLUME controls the output volume. At “0" it is completely OFF.
At “10" it is loud.
