Typical uses
The Lehle Parallel L universal properties make it equally suitable for live use on stage and in the concert hall, and for studio recording sessions. The
following few pages show a number of typical applications in which the Lehle Parallel L is a rational addition to your gear!

Without a Lehle Parallel L, injecting effects into the signal path can cause all kinds of problems, especially if you're using older, so-called "vintage"
effects which, as every player knows, produce a unique sound, but generally falsify the original signal very noticeably. The Lehle Parallel L will help
you here in several ways:
Optimum effect level: Because you can to select an optimum mix ratio between the original and the effect by using the MIX controller (9), you can
Y
mix exactly the amount of effect you want into the original signal.
Minimum noise: The ability to adjust the level of the effect device connected using the Send and Return controllers means that noise is reduced to
Y
the absolute minimum. It can be a good idea to increase the Send level when using effect units that generate powerful background noise, since
this enables you to get more signal and less noise in the effect sound.
No sound losses in Bypass mode: The True-Bypass switch (12), with its gold-plated contacts, makes sure that the signal passes through switched-
Y
off effect units with no loss (genuine "True-Bypass").
What to do:
1. Connect your instrument to the Input socket (1) of the Lehle Parallel L.
2. Connect your amplifier to the Output socket (6) of the Lehle Parallel L.
3. Connect the Send socket (3) of the Lehle Parallel L to the input of your effect unit.
4. Connect the output of your effect unit to the Return socket (5) of the Lehle Parallel L.
5. Use the Send (8) and Return (10) controllers on the Lehle Parallel L to adjust the level of the effect unit connected optimally.
6. Use the MIX controller (9) on the Lehle Parallel L to select the desired effect level.
7. Use the True-Bypass switch (12) to switch between the instrument's original signal and the mix of original and the effect signal (the LED will then
show red).

Many amplifiers feature only one serial effects loop, which means that the signal is routed entirely via this loop between the preamp and the power
amplifier. In many cases, the level on the serial effects loop will be too high for any effects pedals which you might try to connect at this point. The
Lehle Parallel L enables you to adjust the level for these effects optimally by turning the Send controller (8) down slightly. Turn the Return controller
(10) up again, to increase the level back to that of the amplifier's effects loop.
The signal will often lose warmth, intensity and depth - everything, that makes up the unique sound of a good tube amplifier! - when digital effect
processes are used in a serial effects loop. With the Lehle Parallel L, however, you can add the effect signal to the original sound - with the pleasing
result that you lose none of your amplifier's excellent sound characteristics and don't have to do without the effect sounds you love.
What to do:
1. Connect the Send output from the serial effects loop of your amplifier to the Input socket (1) of the Lehle Parallel L.
2. Connect the Output socket (6) of the Lehle Parallel L to the Return input of your amplifier's serial effects loop.
3. Connect the Send socket (3) of the Lehle Parallel L to the input of your effect unit.
4. Connect the output of your effect unit to the Return socket (5) of the Lehle Parallel L.
5. Use the Send (8) and Return (10) controllers of the Lehle Parallel L to adjust the level of the effect unit connected optimally.
6. Select the desired effect level using the MIX controller (9) on the Lehle Parallel L.
7. Use the True-Bypass switch (12) to switch between the instrument's original signal and the mix of the original and effect signals (the LED will then
show red).
