The API 3124MV is a 4-channel mic preamp with an additional audio mixer with transformer balanced output.
The API 3124 is similar to the 3124MB+ but adds variable output level control adding more flexibility suited to modern recording workflows. It also uses a 3:1 output transformer switch lets you change the amount of gain provided by each stage (input, transformer and output) while using the variable output to keep the levels in check.
