System 3: Distance Learning
This illustrates a distance learning application using
broadband video that requires reinforcement of the teachers’
Mics. There are 2 teacher Mics and 10 student Mics, a
connection to 3 other classrooms using a video demodulator,
a VCR and a video modulator. The mics are evenly spread
between the ECM 82es. To reinforce the teachers, the Post
Gate Outputs from these mics on the ECM 82eA #1 are tied
together and connected to the Input of Port 6 on the ECB 62e.
Port 6 is then routed to the Output of Port 3. Since the Output
impedance of the Post and Pre Gates are 300 ohms, tying
these Outputs together creates a passive mixer. Do not use
P3
Prog Contribute when local Mics are routed to Port 3.

1 ECB 62e Base
1 ECM 82eA Mixer with Echo Canceller
1 ECM 82e Mixer
1 MA 3 Multichannel Amplifier with TF 407 transoformers
RaneWare Setup
The file for this application is called AP3V2.ECS, located
on the RaneWare disk. This file has 8 preset operational
Memories.
Memory 1 - Room Controller operational mode. In this mode
all Port Outputs have their Input select checkboxes cleared
and all Mic Inputs are
Active and set to Automatic opera-
tion. This is performed by selecting the Port Memory
settings from Preset Memory 1 at start-up, allowing the
Room Controller to know the start-up condition of ECS.
Memory 2 - Selecting this Preset Memory connects the
Conference Room (Port 1) to Video Network 1 (Port 2).
Memory 3 - Selecting this Preset Memory connects the
Conference Room (Port 1) to Video Network 2 (Port 3).
Memory 4 - Selecting this Preset Memory connects the
Conference Room (Port 1) to Video Network 3 (Port 4).
Memory 5 - Selecting this Preset Memory bridges the Confer-
ence Room (Port 1), Video Network 1 (Port 2), Video
Network 2 (Port 3) and Video Network 3 (Port 4) together.
Memory 16 - Preconditions the Port Inputs and the Mic Inputs
for alignment.
