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.

CUSTOMIZING ECS

Before installing ECS components, there are a few options

that need to be determined first. All but one of these require

removing the top covers before installation.

ECS 62 STEREO EXPANSION MODULE

See the description and installation diagram of the ECS 62

Stereo Expansion module into the ECB 62e Base on page HW

Manual-6. The ECS 62 installs by seating the card onto

factory installed standoffs on the motherboard.

ECB 62e BASE WITH BOTH STEREO & MONO

PORTS

The ECB 62e Base and ECS 62 Stereo Expansion module

are shipped with jumpers in the stereo position. Both mono

and stereo sources may be used by changing the Mono

Jumper blocks as described on page HW Manual-6.

Mono Input signals must be wired to both the Left and

Right Inputs of the Base. Both Left and Right Port Outputs

produce the same mono signal. See Figure 1 below, and page

HW Manual-12 for mono source cable wiring.

Only the bottom ports (Right Channel) are monitored by

the Base. Therefore, threshold detection and metering are not

operational from the ECS 62.

ECM 82eA MIXERS WITH AEC

Systems may or may not require an AEC. Systems that do

require an AEC are those that require teleconferencing.

Although most video codec's have an AEC, their AEC

typically cannot operate with auto-mixers. It is always best to

use the ECM 82eA with a video codec. Systems not requiring

an AEC are those that only require speech reinforcement.

There are times you may wish to install multiple ECM

82eA’s. These are systems with a group of table microphones

where the General or Chairperson sits, and a group of ceiling

microphones or a gallery area. For these types of systems you

may want to set the table's ECM 82eA to soft suppression and

the other ECM 82eA to moderate or strong suppression. For

these types of systems connect each MIX OUT of the ECM

82eA to its respective MIX # input on the ECB 62e.

ECM 82e MIXER POST-GATE/PRE-GATE SWITCH

When installing a sound system with zones, it’s best to use

a Post-Gate mix of the Mics to create a Zone from the AUX

Output. This maintains the NOMM level for the Mixer. See

Applications - System 4 in the RaneWare Operators

Manual.

RaneWare note: the AUX Output is not turned On or Off

from the Mixer Output control.

This switch is set to Post-Gate at the factory. For installa-

tions requiring recording, place this switch in the Pre-Gate

position. This provides a more natural sounding recording.

This switch is located inside the ECM 82e Mixer. See the

diagram on page HW Manual-10.

ECM 82 MIXER PRE-AEC/POST-AEC SWITCH

Under normal circumstances a single AEC is used for 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. For this type of configuration the MIX IN switch

on the ECM 82eA must be placed in its PRE-AEC position.

Rane ships the MIX IN switch on the ECM 82e in PRE-AEC

position.

The ECM 82e Mixer is shipped with the MIX IN (on the

rear panel) being mixed with the microphones before the

Echo Canceller. The internal MIX INPUT switch allows the

MIX IN to be combined with the microphone signals before

the Echo Canceller, thus providing echo cancellation to the

microphones of the upstream Mixer. To change to the Mix

Input to the pre-Echo Canceller setting, set the internal MIX

INPUT switch to the POST-AEC position. See the diagram on

page HW Manual-10 to locate the switch.
