About This Listing
The Pure XLR Preamp has the same great sound and super low
noise as the time-proven K&K Pure Preamp
with the addition of a DI balanced XLR out and a phase switch. It is
9-volt battery or phantom power operated, features a 1/4" line-out,
plus the XLR active balanced output in a compact package.
The Pure XLR Preamp is specially designed to complement our
line of Pure pickups. However, 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.
An LED light indicates if phantom power is present.
The unit can optionally be powered by a 9-volt battery, which will not
be drained as long as the phantom power provides more than 10 volt.
Frequency response is 10-30,000Hz. The bass
control is set to roll of 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.
Phase
switches are usually marketed as a feedback-controlling device, but
they accomplish more than just that. Every acoustic instrument projects
sound waves in a certain phase. The phase that is projected out of the
amplified speaker source needs to be "in phase" with the acoustic
instrument's own soundwaves or the result will not be optimal. If the
amp projects in the opposite phase, the acoustic instrument will fight
its own sound and no balanced tone can develop. Round and warm tone is
only achieved when acoustic and amplified sound oscillate in the same
phase. The Pure XLR Preamp's phase switch allows for instant
correction of this problem.
