The SPC 4 is an antenna combiner designed for the IVM 4 in-ear monitor system.
The antenna combiner allows you to combine the output signals of up to four SST 4
stereo transmitters into a single antenna signal. The SPC 4 will only operate with the
SRA 2 W passive directional antenna or RA 4000 W passive omnidirectional antenna
from AKG.
The SPC 4 can be powered either from an AC adapter with an output voltage of
12 VDC/≥1.4 A (not included) or the optional PSU 4000 central power supply.
