Equipped with the same features as EM 2000 but designed as a twin receiver,
EM 2050 makes it possible for the RF signal to be looped through with the help
of an integrated active splitter. With this design, you can set up systems with
up to 16 channels without using external splitters. An integrated equalizer and
guitar tuning device complete the package.
