Pure XLR Preamp - This offering from K&K uses the electronics of their standard beltclip Pure Preamp, but provides a DI balanced XLR out socket as well as a 1/4" line-out, plus a phase switch to ensure that your instrument is acoustically matched to your speaker system.
It is particularly well-suited to K&K's Pure pickup range, but due to its adjustable input gain and wide frequency range it will work with many more applications. The Pure XLR Preamp features +/-20 db bass, mid, and treble controls, plus an adjustable input gain control. Its simple and super-noiseless circuit provides unsurpassed clarity and power and the adjustable input gain allows you to dial in the precise amplification factor needed for your instrument.
It is 9-volt battery or phantom power operated. An LED light indicates if phantom power is present. The battery will not be drained as long as the phantom power provides more than 10 volts.
Frequency response is 10-30,000Hz. The bass control is set to roll off at 100Hz, the midrange at 1.5kHz with extra large bandwidth and the treble are set at 10kHz. Input impedance is 1 meg. Output impedance on balanced XLR and 1/4" line out is 100 Ohm. The 1/4" line out can conveniently be used as a monitor out or for connection to a tuner.
It's comparable with the Baggs Para DI preamp - while it lacks the Baggs' notch filter and has simpler EQ, it's very high quality and is more robust for stage use.
