    ABOUT THE PURE XLR PREAMP

    The Pure XLR Preamp has the same great sound and low noise circuitry asthe best-selling K&K Pure Preampwith the addition of a DI balanced XLR output and a phase switch.

    The Pure XLR Preamp is specially designed to complement our line ofPure pickups. However, due to its adjustable input gain and widefrequency range it will work with many more applications. The Pure XLRPreamp features +/-20 db bass, mid, and treble controls, plus anadjustable input gain control. Its noiseless circuitry providesunsurpassed clarity and power and the adjustable input gain allows youto dial in the precise amplification factor needed for your instrument.

    The addition of the phase switch is one of the most important tools forlive sound amplification of any acoustic instrument. Phase switches areusually marketed as a feedback-controlling device, but they accomplishmore than just that. Every acoustic instrument projects sound waves ina certain phase. The phase that is projected out of the amplifiedspeaker source needs to be "in phase" with the acoustic instrument'sown soundwaves or the result will not be optimal. If the amp projectsin the opposite phase, the acoustic instrument will fight its own soundand no balanced tone can develop. Round and warm tone is only achievedwhen acoustic and amplified sound oscillate in the same phase. The PureXLR Preamp's phase switch allows for instant correction of this problem.

    An LED light indicates if phantom power is present. The unit canoptionally be powered by a 9-volt battery, which will not be drained aslong as the phantom power provides more than 10 volts.

    Frequency response is 10-30,000Hz. The bass control is set to roll ofat 100Hz, the midrange at 1.5kHz with extra large bandwidth and thetreble are set at 10kHz. Input impedance is 1 meg. Output impedance onbalanced XLR and 1/4" line out is 100 Ohm. The 1/4" line out canconveniently be used as a monitor out or for connection to a tuner.
