Rane ECM 64 - Manual (Page 14)

Manual-14
Advanced Application
Connecting the ECM 64 to a larger ECS
In this application the system required:
• Full duplex audio for a Video Codec and a telephone
connection
• Automatic mic mixing with acoustic echo cancelling of 15
table top, 2 podium and 2 wireless microphones
• Speech reinforcement of 2 podium and 2 wireless mics
• Playback of stereo audio sources from an audio router, a
VCR and a DVD player
• Recording of the audio sources
• Assisted listening of the audio sources
Rane Equipment:
1 - ECM 64 Conference System with
1 - DH 1 Digital Hybrid (included in ECM 64AD)
1 - ECB 62 Base Unit with
1 - ECS 62 Stereo Expansion card
2 - ECM 82A Automatic Mic Mixer with
2 - ECA 1 Acoustic Echo Cancellers (included)
2 – RPD 228d Programmable Equalizers
Refer to the diagram on the following page.
While designing a large audio system for a client that
requires 19 mic inputs, the client informs you he only has
enough audio budget for 2 ECM 82As. Before telling your
client there is no way, here is a solution. Since the ECM 64
has 4 Mic Inputs, use these for the speech reinforcement mics.
In RaneWare, route the
Mic Mix to Out 1, and connect OUT 1
to Input 8 of an ECM 82A. Set the ECM 64’s Output Trim of
Out 1 to –10 dB in RaneWare. Turn the ECM 82A Input 8’s
Phantom Power off and set the Input Gain to +6 dB.
For speech reinforcement of the podium and wireless mics,
route the Mic Mix to Out 3 of the ECM 64 in RaneWare.
To perform a telephone conference:
• Route the HYBRID audio to Out 2 of the ECM 64
• Connect OUT 2 to PORT 6 IN on the ECB 62
• Route
PORT 6 IN to PORT 1 OUT (Program) and PORT
2 OUT (Codec)
• Route PORT 1 and PORT 2 IN to PORT 6 OUT
• Connect ECB 62’s PORT 6 OUT to the ECM 64’s LINE IN
• Route
LINE IN to the HYBRID
For this application load AP2.C64 using

Memory 1 – Only sends the ECM 64’s four mics to the
ceiling speakers.
