A further, entirely practicable use of the Lehle Parallel L is as an active DI box. The unfalsified signal is then routed via the Send socket (3) to the
input of a mixer, stage box or an A/D converter or sound card, while the accustomed sound can be heard simultaneously from the amplifier.
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. Use the U/B mode switch (2) on the Lehle Parallel L to select whether the Send output (3) will supply a balanced or an unbalanced signal (see the
instructions for the U/B mode switch above).
4. Connect the Send socket (3) of the Lehle Parallel L to the input of your target device.
5. Turn the MIX controller (9) on the Lehle Parallel L all the way to the right, so that you have 100 % of the original signal on the output.
6. Use the Send controller (8) on the Lehle Parallel L to set the optimum output level.
7. Use the True-Bypass switch (12) to switch the signal on Send ON (LED shows red) or OFF.
8. Done!
Note: The signal present on the Send socket (3) is not electrically isolated from the output. Ground loops may thus occur and cause undesirable
background noise. In this case, a Lehle P-Split II, which electrically isolates the signals via its built-in LTHZ transformer, and thus eliminates all
background noise, can be connected between the units.
