Rane ECS Hardware 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.
