The Lehle Dual SGoS is the second evolutionary stage of the highly successful programmable switcher for two amps plus tuner. This unit makes it possible to play through two amplifiers individually or simultaneously, either as a stand-alone unit or in a network with other Lehle SGoS switchers. A particularly popular combination is the Lehle Dual SGoS with the Lehle D.Loop SGoS. Programming is as easy and intuitive as you would expect from a Lehle product, and can also be done remotely, using MIDI program change commands. Hum loops are completely excluded, thanks to electrical isolation of outputs A and B by the Lehle LTHZ high-end transformer. Gold-plated-contact relays, ground switches and phase inverters assure the full, loss-free guitar sound. The potentiometers are in the signal path when output A and B are active simultaneously, and the volume of the two amps can be balanced - producing a third sound you've never heard before! Output T, basically intended for instrument tuners, can also be used for a third amp or for a second channel for amp B, opening up even more potentials. The gold-plated-contact relays feature active pop-and-click suppression, outputs A and B can be muted for undisturbed instrument tuning. Welcome to the new Duality! For two amps plus tuner with high impedance LTHZ transformer and gain reduction The Lehle Dual switches the signal via gold-plated relays to outputs A, B or T Outputs A and B can be operated at the same time on two different amps, since A to B is galvanically isolated by the high-end transformer Lehle LTHZ - ground loops are thereby excluded With the potentiometers, the outputs A and B can be attenuated separately The output T is available for a tuner or a third amp The two inputs can be stereo-routed to outputs A and B. In addition, the Lehle Dual has a gold-plated phase reversal and a ground switch The Lehle Dual can be controlled via MIDI and networked with other Lehle SGoS switches Power supply available as an option
