Lehle 1@3



Lehle about the SGoS version

The Lehle 1at3 SGoS is a genuine True-Bypass Switcher that routes the incoming signal to up to three outputs (e.g. amps, tuner, effects). Output B and the C->B socket can be used as a loop, enabling you to switch instantly between the pure original signal and the signal with effects. The Lehle 1at3 SGoS can be controlled and synchronized with other Lehle SGoS Switchers via MIDI.

Lehle (2003)

The Lehle 1@3 enables you to switch between amps via gold-plated relays. The signal is routed with no semiconductors and no corruption to Output A, B or C.

  1. input signal
    The input signal enters this socket. It is automatically routed to A if the Lehle 1@3 is not active, and B and C are therefore muted.

  2. Loop (Return)
    If this socket is assigned and C is activated, the signal applied here is routed to B. In this way, effect units can be serially routed into the amp, which is connected to B. Effects which influence your sound even when not active can thus be bypassed by pressing the B button. This means that they are in the signal path only when they are really needed.

  3. output
    The signal is routed with no semiconductors directly via gold-plated relays to Output A, B or C provided the corresponding button has been pressed. The input signal can only be routed to one output. The other two outputs are therefore muted. In case of a power unit failure the signal will be routed to A.

  4. power supply
    The Lehle 1@3 requires a power supply of between 8 and 20 V. Polarity is of no importance. The supply voltage is internally rectified and stabilized in order to guarantee trouble-free operation. A thermal cut-out automatically trips and switches the unit off if a short-circuit occurs. A correctly fitting plug connector for the power-supply socket of the Lehle 1@3 is supplied. This can be soldered to the required power unit if necessary.

  5. Master-Slave with other switchers
    Each Lehle 1@3 can be easily retrofitted with a DIN socket in order to permit parallel operation with other Lehle switches in master/slave mode.

  6. LEDs behind a magnifying lens
    The high-intensity LEDs installed behind a magnifying lens make it easy to read the switching state (A, B or C) even under spotlights.

  7. indestructible switching mechanism
    The buttons which control State A, B or C are actuated inside the switch by means of a virtually indestructible switching mechanism.

  8. solid box / easy to fix
    The base of the Lehle 1@3 can be secured without difficulty. First remove the four housing screws for the cover, and then screw the base of the switch to a base-plate using the two screws supplied with the unit, the washers and the spacer elements.
