VPM220 Cascading
The VPM220 provides 360° sound pickup and an optimal pickup range of six meters. In a
large conference room (of about 40 to 50 square meters) with only one VPM220, audio far
from the VPM220 becomes problematic; cascaded VPM220s can help alleviate this problem.
Dynamically cascading, connecting, or disconnecting VPM220s will not interrupt a
conference.
The TE40 and TE50 can be connected to only one VPM220 while the TE60 can be connected
to two cascaded VPM220s.
