[. . . ] Adjust the Notch control until this feedback is eliminated (usually between one and two o'clock on the dial). 3 Prefix - Stereo Blender 3. Increase the volume some more and play (on the low E string) the fifth fret A and above. Flip the phase switch to the position that eliminates feedback in this region. Slowly increase the Volume again, until you start to hear a high squeal. Lower the Contour slider all the way down and adjust the Frequency slider until the squealy feedback is eliminated. Raise the Contour slider (if possible) to just below the threshold of feedback. See diagram on page 9 SETUP Battery Compartment Pull the small tab at the top of the Onboard BlenderTM toward you. The body of the preamp will swing out, revealing the battery compartment. Observe the polarity marks on the battery clip and install a fresh 9V alkaline battery accordingly. 4 USER GUIDE Microphone Trim Control A small circular potentiometer is located on the side of the preamp that faces the back of the guitar. Set the Blend slider to the center position and with a small slotted screwdriver and adjust the Trim Control until both the microphone and pickup levels are balanced to your taste. Endpin Jack When you plug into the endpin jack, the Prefix Pro Blend switches on. To conserve the battery, remove the instrument cable from the endpin jack when the system is not being used. It is a good idea to turn down your amp or mixer input before you plug into the endpin jack. Doing so will protect your speakers (and your ears) from loud pops. Battery Low LED Plug into the endpin jack and the Low Battery light will flash momentarily, indicating that the power is on. When the Low Battery light stays on, it is time to change the battery. 5 Prefix - Stereo Blender CONTROLS Volume Control This is a master volume control for both the pickup and the microphone. Set this as high as possible (without distorting your amp or mixer) for the cleanest signal. Notch and Phase These controls work hand in hand to suppress two adjacent ranges of acoustic feedback. When you set them properly, you can play your instrument as loud as you like, feedback free. Notch Tune the Notch filter to scoop out the lowest range of feedback when you play bass notes between the open low E string and (up to and including) the forth fret G sharp on the same string. Low frequency "cavity resonance" feedback can usually be squelched by setting the Notch control between one o'clock and two o'clock on the dial. Note that for instruments that do not suffer from low frequency feedback, the notch can be defeated by moving the dial to the Off (seven o'clock) position. Phase Switch Flip the Phase switch back and forth until you find the position that sounds best and subdues mid-bass feedback. Mid-bass feedback generally occurs when you play bass notes above the fourth fret G sharp on the low E string. Bass This control affects the under-saddle pickup signal only!A Boost here will add depth and weight to the sound the instrument. 6 USER GUIDE Lower Feedback Range (E to G#) Upper Feedback Range (A and above) 7 Prefix - Stereo Blender Contour EQ The Contour slider and the Frequency knob make up this EQ.
