Speck Electronics LiLo - Manual (Page 8)

An important benefit of the LiLo is the ability to mix 32 line signals in “real
time” from the standard 16 channel mixer (or 48 with the 24 channel LiLo).
You could, for example, have the 16 outputs from D/A converters (Protools,
Radar, etc.) connected to the 16 "Line-B's" and at the same time the "Line-
A's" can be used for 16 other line signals such as mic preamps, samplers, or
additional outputs from D/A converters...all ending up at the stereo and group
mix busses.
The dual path signal routing is possible because the LiLo's input channels use
separate line preamps for Line-A and Line-B rather than switching XLR
inputs into a common preamp stage. This combination of dual channel line
amps, Group Select switch [12], and Aux Select switch [20] can virtually
double the input capacity of the LiLo.
Figure 2 shows one example of the “dual path” signal flow. In this example,
the Group Select switch is pushed to select Line-B as the source for the GRP
1 and GRP 2 assign switches. The group assigns are then routed to their
respective master that are then mixed to the stereo mix output. At the same
time, Line-A is mixed through the channels fader, pan, and mix assign.
