LA-40mkII
TA SCAMs  LA-40mkII w as built with the same top notch line lev el converters  as the  LA-80 a nd LA-81, but combines both directions of  conversion in onebo x.   Fine tuning trim pots are accessed on the front panel, off ering ±6dB adjustment on individual outputs.   Ground lift controls  are available  on each channel or globally f or eliminating ground loops.  A channel link ma trix on the bottom  of the LA-40mkII allows channels to be  linked, utilizing the  line amp as a distribution  amplifier.  This is  great for splitting signals for distribution to  multiple recorders or  for multizone sound routing.
