The LA-40mkiii, LA-80mkii and LA 81mkii line level converters are built for studio quality conversion
between balanced (+4 dBu/–20 dBu) and unbalanced (–10 dB) line levels, offering the best integration of all types of equipment. LA-40mkiii is equipped with four RCA inputs and outputs as well as four XLR inputs and outputs. LA-80 MKII offers eight unbalanced RCA inputs and eight balanced XLR outputs, and LA-81 MKII has eight balanced XLR inputs and eight unbalanced RCA outputs. Each of the three converters has a switch matrix that allows channels to be linked, utilizing the unit as a distribution amplifier for splitting signals
to multiple recorders, or for multizone sound routing applications.
Switches on the bottom panel allow to select a nominal level of +4 dBu or –20 dBu for each channel and ±12 dB trim pots on the front panel make perfect level matching easy. LEDs on the front panel indicate signal presence for each channel. Ground lift switches are available on each channel or globally for eliminating ground loops.
