LA-80/LA-81

LA-8081
Line Amplifiers

The LA-80 and LA-81 line level converters were built for studio quality conversion between balanced and unbalanced line levels, offering the best integration of all types of equipment. Fine tuning trim pots are accessed on the front panel, offering ±6dB adjustment on individual outputs. Ground lift controls are available on each channel or globally for eliminating ground loops. On the bottom of the LA-80 is a channel link matrix that allows channels to be linked, utilizing the Line Amp as a distribution amplifier for splitting signals to multiple recorders, or for multizone sound routing applications.
