Sennheiser ASP2 Passive Antenna Distribution
Passive 2 x 1 : 4 antenna splitter. The ASP 2 allows a single pair of antennas to feed up to four EM 500 G2, EM 300 G2 or EM 100 G2 receivers. Incorporates DC distribution for distributing the DC supply voltage of the NT 1 power supply unit to up to four receivers.
By combining two ASP 2, an 8-channel system can be operated with only two antennas.
