The Lehle Sunday Driver XLR is a compact­format high-end preamp for all types of electrical
and acoustic instruments - a preamp that enables
electric guitars and basses, acoustic guitars, and
also other stringed instruments (such as violins,
cellos and double basses) to unfold all of their
musical potential.

The XLR variant is equipped with a balanced XLR
output and a ground-lift switch. On stage, it can
be used as a compact DI box and as a line driver
for long cable distances. In studio use its broad
output range of 20 to 100,000 Hz makes it ideal
as a recording preamp or as a DI box, whether as
a battery-operated stand-alone unit, or integrated
into existing setups.
The Lehle Sunday Driver XLR, with its high­quality JFET technology, provides two modes,
which are selected by a switch with gold-pla­ted contacts. In mode D for “Driver” (switcher
pressed), the input signal is amplified with
absolutely no modification. This eliminates the
signal losses that long cable routings and/or
impedance matching errors with high-impedance
signals from passive pickups can cause. The signal

remains powerful and clear, retaining its dynamics
and brilliance. Mode S for “Sunday” (switcher not
pressed) multiplies the input impedance by four,
bringing out previously inaudible details. As gain
increases on the Lehle Sunday Driver XLR, the
sound takes on an unmistakable and characteristic
warmth. There is no distortion at any stage, and
the signal remains clean at all times, even at the
maximum gain setting of 15 dB. To exploit the
dynamics to the full, the input voltage is rectified
from the power supply socket, filtered, stabilized
and then doubled to 18V. The Lehle Sunday
Driver XLR is totally free of background noise,
thanks to its studio-standard signal-to-noise ratio
of better than -100 dB.
