The Lehle 3@1 enables you to
switch between a range of instruments in stereo via gold-plated relays.
The signal is routed with no semiconductors and no corruption via inputs
A, B or C to the outputs.
1.
Output The stereo signal is routed directly via gold-plated relays to
the two outputs. One output can, for instance, be connected to the
amplifier and the other used for the tuner.
2. The stereo signal is routed directly via gold-plated relays
optionally via Input A, B or C to the two outputs. Volume on Inputs B
and C can be adjusted by means of trim pots. It is necessary to remove
the housing cover using its four screws in order to set the
potentiometers the first time. The potentiometers are located at the
same level as their inputs.
3. The input signal from A is automatically routed to the two outputs if
the Lehle 3@1 is not active.
4. Power supply The Lehle 3@1 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 jack of the Lehle 3@1 is supplied. This can be soldered to
the required power unit if necessary.
5. Master-Slave with other switchers Each Lehle 3@1 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 3@1 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.
