four endpoints listening.
Two Users Talking on Same Channel / Four Users Listening
Figure 8
Examples
Workflow (worst-case scenarios where most or all talk keys are latched):
Theater: 1 HMS-4X, 20 HXII-BP, 8-10 channels. 1 Production channel, HXII-BP evenly
distributed on other channels (3-4 persons per channel), all over IP (connected to a
single 24 port switch)
Rehearsal: All Talk latched, many people listening to 2-3 persons talking at the same
time.
Bandwidth usage:
- 300kbps from each HXII-BP to switch
- 600-900kbps from switch to each HXII-BP
- 20*300kbps = 6Mbps from switch to HMS-4X
- 20*(600-900) = 12-18Mbps from HMS-4X to switch
Larger Theater: 3 linked HMS-4X, 39 HXII-BP evenly distributed over the 3 HMS-4X, 15
channels.
Rehearsal: All Talk latched, many people listening to 2-3 persons talking at the same
time.
Bandwidth usage:
- 300kbps from each HXII-BP to switch
