Rane ECM 64e - Manual (Page 4)

Manual-4
Typical ECM 64eAD Installation
The ECM 64eAD is preprogrammed to operate out of the
box using the following system configuration. Run RaneWare,
choose
Device > Restore Memories from File, and load the
ECM 64e file AP1.C64. In this example we will not use
custom names, just the defaults to keep things clearer.
In this configuration:
• Mic Mix is routed to the AEC IN
• Out 1 is used for the AEC REF
• Line, AUX and HYBRID are routed to Out 1 (to the
loudspeaker amplifier)
• AEC OUT, AUX and HYBRID are routed to Out 2 (to the
video codec)
• Mic Mix, Line, AUX and HYBRID are routed to Out 3 (to
the record VCR)
• AEC OUT, Line and AUX are routed to HYBRID.
The AP1.C64 file uses two Memories:
• Memory 1 is set for the above application
• Memory 2 allows local speech reinforcement.
In Memory 1, since Out 1 is used for the AEC Reference,
Mics cannot be sent to Out 1 for local speech reinforcement. If
Mics are sent to both the AEC Input and the AEC Reference,
the AEC will not perform properly.
The Memory 2 application solves this problem by chang-
ing the AEC Reference from Out 1 to the mix of Line In and
Aux In. Since Out 1’s Limiter is no longer part of the AEC
Reference, Memory 2 disables Out 1’s Limiter.
See Memory & Security on page Manual-9 for more
information.
Refer to the Appendix for an example of a larger system
combining the ECM 64e with ECS.
