The Lehle Sunday Driver is a high end preamp with a convenient compact format.
The Lehle Sunday Driver XLR is a compact-format 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 realize all of their musical potential. The XLR variant adds a symmetrical XLR output and a ground-lift switch to the classical Lehle Sunday Driver spec.
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 high-quality JFET technology, provides two modes, which are selected using a switch with gold-plated contacts. In mode D (= Driver), 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 pick-ups can cause. The signal remains powerful and clear, retaining its dynamics and brilliance. Mode S (= Sunday) multiplies 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.
