GAINControls the amount of Gain introduced to a Preset. The higher the Gain, the harder the preamp is driven.4. BASSTurning the BASS control will adjust the warmth and low-end depth of your sound.5. MIDDLEAdjusting the MIDDLE control will vary the amount of body in your sound by boosting or cutting midrange frequencies. 6. TREBLEIncreasing the TREBLE will make your sound brighter and more cutting. Turning the TREBLE down will decrease tonal edge and make the sound softer. 7. VOLUMEControls the volume level within a selected Preset. Because GAIN, BASS, MIDDLE, TREBLE & VOLUME are stored as part of a Preset, these panel tone controls only become active when they are used. This means that until they are turned their position is not related to their setting within a Preset. When you turn a tone control it becomes active. The display screen will show its current setting and the stored setting. When a GAIN, BASS, MIDDLE, TREBLE or VOLUME control is activated the EXIT/STORE LED will flash red to show that the Preset’s stored settings have changed.7810131412212322111.
