It consists of two paths that share a common control knob which works both as a variable attenuator for the SEND path and a variable boost control for the RETURN path, so the net gain of the whole system is unity. The range of the SEND loss/RETURN boost control is from -6dB to -30dB ref. line level, but it can be additionally shifted down by 20dB using a push button on the front panel. Some guitar effects are not designed to be in-phase, so when using such an effect via the LLI-5A and doing parallel processing some phase cancellation may occur. To overcome that issue a phase polarity switch is included in the send path of the LLI-5A. The SEND path, which also includes a ground-lift switch, can be used as a "re-amping" tool. The RETURN path can be used as a clean DI. The operation of the LLI-5A module comes down to connecting effects in the loop, choosing the proper phase and setting the right operation level. Too high an operation level results in excessive distortion from the effects in the loop, whereas too low level results in excessive noise. The LLI-5A is extremely easy to use and features very short signal path ensuring high sound quality.
