ECM 64e
CONFERENCE SYSTEM
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.

CONFERENCING SYSTEM
ECM 64e Applications
For simple external control, using switch closures, use the
MRP/EXT (DB-15 female) connector on the rear panel. From
this connector memories can be recalled and some control
functions can be performed. Control functions on this
connector include Off Hook, Privacy, Volume Up and Down
and Mute. Status signals are also available from this connector which include Off Hook, Privacy, Mute and Ring.
Full control of the ECM 64e, including programming,
DTMF dialing and receiving status signals are available via
the rear panel RW 232 port. This port can interface directly to
any RS-232 port on a personal computer or control system.
Status LEDs on the front of the ECM 64e indicate Input
and Output Signal present and Overload conditions, Off Hook
(OH), Ring (RNG), Privacy (PRV), Mute (MUT), AutoAnswer (AA), a monitored input or output Level Meter, RW
232 communication (COM) and Power.
Front panel controls include Mic Gain switches for Line
or Mic inputs, OFF HOOK to connect to and disconnect from
a telephone call, VOLUME DOWN and UP to control
Program (OUT 1) level, and PORT STEP to select which
Input or Output to monitor on the LEVEL Meter.
• ECM 64e by itself - Small presentation room requiring a
programmable audio system with up to four microphones,
two line inputs and three outputs. Combined with a Rane
SRM 66, the ECM 64e makes a great audio system for hotel
room combining.
• By installing the DH 1e, the ECM 64e becomes a digital
hybrid to interface with a standard POTS type telephone
line. This is also a useful add-on to the larger ECS (ECB
62 with an ECM 82a).
• By installing the ECA 2, the ECM 64e becomes an audio
system for a small video conference room connected by a
four-wire device, such as a video codec or a personal
computer that supports Voice Over IP.
Non-Volatile Memories
Batteries not included. All memories are stored in an
Electrically Erasable Prom (EEPROM) with a data retention
of 200 years. Stored Memories may be recalled by remote
switch contact closures using the Memory Recall Port (MRP)
or RS-232. The translation between switch closure and the 16
Memories is programmable. Current settings, called working
memory, are also non-volatile. Selecting a memory transfers
its contents to working memory.
Typical ECM 64eAD installation
The ECM 64eAD is preprogrammed to operate out of the box
using the following system configuration:
• Mix In routed to the AEC In
• Out 1 is used for the room speakers and the AEC Ref.
• Line In, Aux In and Hybrid routed to Out 1 (Program)
• AEC Out, Aux In and Hybrid routed to Out 2 (video codec)
• Mix In, Line In, Aux In and Hybrid routed to Out 3 (VCR)
• AEC Out, Line In and Aux In are routed to the Hybrid

with a four-wire device, such as a Video Codec or a
personal computer that supports Voice Over IP.
• Small conference room requiring full duplex conferencing
with both a standard POTS type telephone line and a fourwire device.

RaneWare®
Rane’s software called RaneWare (under Windows 95
and 98SE), is included at no extra cost, allowing the units to
be controlled in real time. RaneWare is available free from
Rane’s website, www.rane.com. The software’s easy-to-use
graphical interface features control of all parameters, and
extensive on-line help. Memories may be recalled, copied,
and stored. A Site Control window is provided with password
protection so that all units can recall stored memories without
further access. Local Edit mode allows parameters to be
viewed and edited without affecting a unit. These parameters
can then be sent to a unit or saved in a file. The software is
operational even without an ECM 64e connected, using an
offline device. The Rane RPD 1 may be used to control the
ECM 64e from a remote location using a modem. Also the
Rane Via 10 Ethernet Bridge allows remote control of the
ECM 64e over a 10Base-T Ethernet.
