Lehle Little Dual A-B-Y Maximum SignalFidelity Amp Switching Guitar Pedal



 

 

TheLehle Little Dual is the Lehle Dual SGoS's little sister, a maximumsignal-fidelity amp switcher for two amps. Both amps are activatedsimultaneously using the left footswitch, while the right is used toswitch back and forth between them. High-intensity LEDs make it easy toread off switching state A or B, or A and B, even under high-powerspots.
The centerpiece of the Lehle Little Dual is its high-end Lehle LTHZtransformer, which electrically isolates output A from output B, makinghistory of hum loops - permanently! The Lehle Little Dual features agold-plated-contact phase inverter and a gold-plated-contact groundswitch. The two inputs can also be routed in stereo to outputs A and B,if you use the stereo signal of an effect unit as the input, forexample. This also makes it possible to route instruments equipped withtwo pick-ups, including many acoustic and hybrid guitars, and alsodouble basses, via two amplifier systems - with no complications. Thesesystems can be operated either in alternation or in parallel - withouthum, and without sound losses, needless to say! The Lehle Little Dual -small, but so utterly effective!

Q:What is galvanic isolation?
A:Background noise, generated by ground loops, occurs again and againwhen two electronic devices are connected to each other, and the LehleLittle Dual provides a simple but extremely effective remedy wheninstalled between the two units. The two devices are electricallyisolated when the `A´ output is used, eliminating this background noise.
The protective earth conductor and the ground connection of the audiosignal create a loop which will pick up external interferencegenerated, for example, by coils. Such interference will impair thesignal. The Lehle LTHZ transformer included in the Lehle Little Dualelectrically isolates the ground connection. The hum loop is thusbroken at this point.

Q:Does the galvanic isolation color my sound?
A:No, neither sound nor dynamics will be altered, the signal is passingthe switcher without any loss in strength or frequency. We use ourself-developed Lehle LTHZ transformers for this, the selection of highquality components guarantees a rich sound throughout the fullfrequency range.

Q:Is the signal suitable for a mixer/recorder? I would like to play thrumy effects and simultaneously record a dry signal for later re-amping.
A:No problem, just make sure the mixer/recorder features a HiZ input,otherwise the instrument will sound flat and lifeless. Optional theoutput signal can be balanced by using a TRS to XLR connection.

Q:Can I use the Little Dual for acoustic guitars with onboard preamp?
A:Absolutely! The switcher works passively and can handle all kinds ofaudio signals without distortion or loss, for weaker piezo signals aswell as stronger line level signals.

Q:Can the Little Dual/Dual SGoS be used as DI box since it has 14"sockets?
A:Yes, you get a balanced or unbalanced (mono-) signal fromtransformer-isolated output A when using a stereo (TRS) cable.

Q:Does it affect the sound and dynamics of my instrument when I use theLittle Dual without power supply? In the manual it says the power isonly for the LEDs.
A:It makes no difference since the switcher works passive. Power isindeed only for the LEDs, neither dynamics nor sound will be altered inany way.
