Gold-plated Relays & Switches
The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts need to be made of special materials to permit loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.

Switching precise, swift and quiet
Swift and precise switching as between different instruments, effects loops or amps is essential in many live setups. To ensure this almost silently and wear-free, we have designed a finely tuned control system with a self developed spring located between the foot switch, our famous mushroom head, and the actual sensing device on the circuit board. A processor based on the ARM Cortex-M technology controls the switching operation very fast and precisely. While a conventional switch can handle a maximum of 20,000 switching operations, the interplay of the components used here enables a service life of 2 million switching operations. A hundred times more!

LEHLE Footswitch
The easy-action mushroom-shaped buttons characteristic of LEHLE products are mounted in the cover, so that your foot pressure is transmitted indirectly only, via a spring. Thus the electronics board is not exposed to mechanical loads, making your LEHLE virtually indestructible and guaranteeing years of trouble-free switching.

Voltage Internally Boosted to 30V
To exploit the dynamics of tube amplifiers to the full, the input voltage of Lehle products bearing this symbol is rectified from the power supply socket, then filtered, stabilized and boosted to 30V.

Adjustable Gain
Adjustment of volume or distortion using a gain controller is a vital feature in many situations. The gain controllers on the corresponding Lehle products feature black anodized aluminium knobs set back into the housing so that they can be easily fingertip rotated but keep their settings during performances and transportation.

Stereo
Many effects units feature stereo outputs. Or: instruments frequently have two pickup systems, e.g. a combination of conventional magnetic and Piezo types, to emulate an acoustic sound. Lehle accessories are ideal for trouble-free routing of such dual-channel stereo signals. All stereo-capable Lehle products are, of course, also suitable for mono operation.

Mono-to-stereo-switch
Integrate an effects pedal with a mono input and stereo output into the signal path.

The Lehle Parallel SW II is a compact and versatile line mixer designed to meet the highest tonal standards. The Lehle Parallel SW II mixes the signals from your effects units into your original signal, either before an amp or inserted into its effects loop. You can adjust send and return levels separately, and finely balance the effects signal to the original signal using the mix controller. All connections are realised in stereo, so your stereo effects pedals can be placed into the signal path of the Lehle Parallel SW II.
Thanks to the discrete Class A input stages with JFET technology, the Lehle Parallel SW II's inputs can handle high-impedance signals - from electric guitars, basses or acoustic instruments - as well as low-impedance signals - from keyboards, active electric guitars and basses - with a broad output range extending from 20 to 100,000 Hz.
With the new Lehle Parallel SW II it is now possible to combine mono and stereo signals. You can easily integrate effects pedals with mono input and stereo output into the signal path of the Lehle Parallel SW II without limitations.
The great dynamic range of the Lehle Parallel SW II makes it possible to blend rack-mount studio effects units with low-impedance line level into the guitar signal path, or insert effects pedals with their level-adjusted into an amp's effects loop.
To exploit the dynamics of tube amplifiers to the full, the input voltage is rectified from the power supply socket, then filtered, stabilized and transformed to 30 V.
The LEHLE-Switch works with a microcontroller and an intelligent True-Bypass-Relay-Circuit with active pop suppression circuit, thereby allowing the Lehle Parallel SW II to switch even faster than mechanical switches, noise-free and without wear.
The easy-action mushroom-shaped button characteristic of LEHLE products is mounted in the cover, so that your foot pressure is transmitted indirectly, via a spring. Thus the electronics board is not exposed to mechanical loads, making the Lehle Parallel SW II virtually indestructible and guaranteeing years of trouble-free switching.
The Lehle Parallel SW II has three operating modes, making the switch work as either a latching or momentary switch, allowing for short or rhythmic stutter-effects. The third mode combines a mixture of operating mode one and two: a short hit is latching, a long hit is momentary.
Placing no limitations on your creativity!
We take care of your signal so that you can take care of the music.

Q: Can I use the (serial) amp's fx-loop to mix effects to my guitar signal?
I dont want my signal to go 100% thru stompboxes or digital processors.
A: With the Lehle Parallel SW II only a part of the guitar signal can be blended with effects, the pure signal will not be routed completely thru the fx unit.

Q: How can I mix the two pickups of my instrument? My bass has two seperate outputs for piezo and magnetic pickup.
A: The Lehle Parallel Sw II can blend 2 pickup signals without any signal loss. One signal goes to the units input, the other pickup is plugged into the Parallel´s Return. Now the level and mix controls can be used to adjust your favourite sound.

Q: Does the buffer inside the Lehle Parallel SW II have the same function as the Lehle Sunday Driver?
A: Almost, the Lehle Sunday Driver was developed on the basis of the D.Loop´s buffer and has the option to increase the input impedance from 1MOhm to 4 Mohm. The Lehle Parallel´s buffer does not have this feature, but has a wider range, it works from -15dB up to +15dB.
