Description

The ECM 64e Conference System is part of Rane’s

Engineered Conference System (ECS) line of professional

audio products. When all you have is a small conference room

requiring four mics, two line-level devices and a telephone,

and you want the best in full duplex conferencing, the ECM

64e is the product of choice. Like Rane’s larger conference

system, the ECB 62 and ECM 82, the ECM 64e is flexible in

many different applications. The ECM 64e can work on its

own for presentation and conference rooms, or as an add-on

for the larger ECS.

The ECM 64e has six inputs and four outputs, and is

basically four independent six channel matrix mixers. All

audio inputs and outputs use Euroblock type connections. All

audio connections use Euroblocks. All Inputs are balanced

except for the external AEC Reference which is unbalanced.

Inputs include:

• Four programmable mic or line-level Inputs with rear panel

selectable phantom power that are mixed to one audio mix,

called Mic Mix

• Two programmable line-level Inputs called Line In and

Aux In

• A selectable external AEC Reference.

Outputs include:

• Three programmable balanced Outputs.

• Two unbalanced outputs (AEC Reference Out and AEC

Out).

• When installed, the optional Digital Hybrid (DH 1e)

becomes the fourth programmable Output.

There are two optional modules for the ECM 64e, the DH

1e and the ECA 2. The DH 1e is a Digital Hybrid and allows

for connecting to a Plain Old Telephone Service (POTS), also

called a two-wire phone line. The ECA 2 is an Acoustic Echo

Canceller module, required when using the ECM 64e for

conferencing applications. Using optional modules gives the

system designer more applications flexibility. By ordering the

ECM 64eAD, both of these modules are factory installed.

The ECM 64eAD supports both two-wire and four-wire

audio connections. Two-wire connections use standard

telephone lines. A two-wire line consists of one balanced

audio line used for both the transmit and receive audio paths.

A four-wire connection uses separate audio pairs for the

transmit and receive audio paths. Devices such as a video

codec, audio over ISDN (like the Telos Zephyr™) and

personal computers that support Voice Over IP use four-wire

audio connections.

The ECM 64eAD can operate as a standalone conference

system by itself, with switch closures using the MRP/EXT

Port, or with a personal computer running RaneWare® or

with a RS-232 based control system like Panja or Crestron.

To operate the ECM 64eAD by itself, just connect

microphones, a speaker, a telephone line, and a telephone set

for dialing. From the front panel, use the OFF HOOK button

to connect and disconnect the ECM 64eAD to and from the

phone line, and use the VOLUME buttons for Program level.
