ADDENDUM - LA-2A INSTRUCTION MANUAL
All LA-2A Leveling Amplifiers after serial number 572
incorporate a leveling slope control switch. The purpose of this
switch is to allow s e lection of either limiter or compressor action
in the LA -2A.
Referring to Figure 1, page 8 the typical gain reduction
curve is illustrated for limiter operation. Beyond the break away
point the output does not increase with an increase of input l e vel,
producing a plot which is horizontal. When the switch is set for
compressor operation, the output will increase slightly with
increasing input level. The resulting curve will have a slope of
approximately 3:1, which me ans that an inCl' ea se of input level
of 100% will cause an output increase of 30%.
This switch is located on the chassis adjacent to the
optical a ttenuator (T 4A) soc k e t.
