LEHLE LITTLE DUAL (DISCONTINUED)
The LEHLE LITTLE DUAL is the LEHLE DUAL SGOS's little sister, a maximum signal-fidelity amp switcher for two amps. Both amps are activated simultaneously using the left footswitch, while the right is used to switch back and forth between them. High-intensity LEDs make it easy to read off switching state A or B, or A and B, even under high-power spots.
The centerpiece of the LEHLE LITTLE DUAL is its high-end LEHLE TRANSFORMER HZ transformer, which electrically isolates output A from output B, making history of hum loops - permanently! The LEHLE LITTLE DUAL features a gold-plated-contact phase inverter and a gold-plated-contact ground switch. 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, for example. This also makes it possible to route instruments equipped with two pick-ups, including many acoustic and hybrid guitars, and also double basses, via two amplifier systems - with no complications. These systems can be operated either in alternation or in parallel - without hum, and without sound losses, needless to say! The LEHLE LITTLE DUAL - small, but so utterly effective!
The protective earth conductor and the ground connection of the audio signal create a loop which will pick up external interference generated, for example, by coils. Such interference will impair the signal. The LEHLE TRANSFORMER HZ transformer included in the LEHLE LITTLE DUAL galvanically isolates the ground connection. The hum loop is thus broken at this point.
