1. IN 1 Input jack

 

Connect the left output of your instrument or your stereo 

source here.

The 

Lehle Stereo Volume

 processes signals 

of synthesizers, keyboards, electric and acoustic 
instruments of all kinds, as well as samplers and 
effects units. The input impedance of the 

Lehle 

Stereo Volume

 is approx. 2 MOhm. It does not 

matter whether the connected signal has high or 
low impedance, or if it comes from a passive or an 
active pickup system.
If only this jack is connected, the input signal will 
nonetheless be distributed to both outputs.

2. IN 2 Input jack

 

Connect the right output of your instrument or your 

stereo source here.

If this socket remains free, the signal from IN 1 
will be distributed to both outputs (OUT 1 and 
OUT 2).

3. OUT 1 Output jack 

 

Connect the left input channel of your target device 

here.

For instance, this would be an amplifier, a mixing 

desk, an effects unit or an audio interface. The two 
outputs (OUT 1 and OUT 2) have low impedance 
and do not change their output impedance when the 
volume is altered via the volume pedal. Both outputs 
are balanced and can be tapped by TRS plugs (or 
unbalanced with TS plugs).
If the OUT 2 jack remains free whilst both inputs are 
connected, the 

Lehle Stereo Volume

 merges the 

input signals and sends them to OUT 1.

4. OUT 2 Output jack

 

Connect the right input channel of your target device 

here.

If this socket remains free whilst both inputs are 
connected, the 

Lehle Stereo Volume

 merges the 

input signals and sends them to OUT 1.

5. External power supply

 

Connect your external power supply here (9 -15 V DC 

or 7 -12 V AC).

For the 

Lehle Stereo Volume

 an external power 

supply is required.
This should provide a minimum of 9 V and no 
more than 15 V DC, but alternatively you can also 
connect an AC voltage source with more than 7
