Rane ECS Hardware (ECB 62e and ECM 82e) - Manual

HW Manual-1
ECS HARDWARE MANUAL ECS
ENGINEERED CONFERENCE SYSTEMS
Quick Start
The ECS Operating Manuals are split into two booklets
— one for ECS hardware and one for RaneWare® software.
Neither booklet includes service information. Should any
unit require repair, contact the Rane factory. Telephone, fax
and web info is on the rear of this manual.
Typically, only one ECM 82eA (with AEC) is required
per system. If your system requires more than eight mics,
you can add up to five ECM 82e Mixers (without AEC) for
a total of 48 mics. The QuickAdapt™ algorithm allows a
single AEC to operate the entire system. When using a
single AEC with multiple mixers, daisy-chain the ECM 82e
Mixers together using MIX OUT to MIX IN. The last mixer
in the chain and the one that connects to the MIX 1 input on
the ECB 62e must be the ECM 82eA. Only the ECM 82eA
requires its AEC Reference input to be connected to the
Mono output on the ECB 62e. See RW Manual-17.
Plain Old Telephone Service (POTS) type teleconfer-
encing, also know as phone add-on, requires an additional
Digital Hybrid. The Rane ECM 64e Conference System
with its DH 1e Digital Hybrid module can be added to
provide phone add-on support to the ECB 62e. If remote
diagnostics is desired, then add a Rane RPD 1 Programming
& Diagnostics unit or the Rane Via 10 Ethernet Bridge.
Since ECS is a programmable audio system, it must first
be programmed before it can pass audio. When power is
first applied to the ECB 62e, memory is set with all outputs
muted. For a typical system configuration, recall Memory 1
and inputs will be routed to outputs. To further simplify this
process, just recall Memory 16 and you are ready to adjust
mic levels. See RW Manual-21 for system setup procedures.
For more information there are four system applications in
the RaneWare Operators Manual.
Most echo problems are caused by improper microphone
placement and gain. To achieve good AEC performance, the
microphones must be properly set up, as shown on page
RW Manual-19 (in the ECS RaneWare Manual).
ECS Hardware Manual
This manual begins by explaining the options and
internal settings for each unit, since all optional accessories
must be installed and all internal jumpers set before
installation of the units into equipment racks. Next are
detailed descriptions of the front and rear panel features,
followed by detailed block diagrams and discussions, as
well as diagrams showing the signal flow making up the
critical “offsets,” or thresholds used by ECS. Then comes
instructions on Power, Audio & Data Connections, as well
as how to set each unit’s Device Address. Complete
electronic and mechanical specifications are found in the
Data Sheet.
Information on installing and running the control
software is found in the second booklet: ECS RaneWare
Operators Manual.
