Introduction

Check the included items

The following items are included with the M-480. Make sure that
all of them are present:

• The M-480 itself

• Power cord

* Use only the power cord that was included with the M-480.

• REAC connector covers (three)

• Channel number sticker

• Ferrite cores (four)

• Owner’s manual (the document you’re reading)

• Cover

Conventions used in this manual

985

The explanations in this manual include illustrations that depict
what should typically be shown by the display. Note, however,
that your unit may incorporate a newer, enhanced version of the
system, so what you actually see in the display may not always
match what appears in the manual.

Names

The following input/output units can be connected to the M­480’s REAC ports:

• S-1608 stage unit

• S-0816 FOH unit

• S-4000S 40-channel I/O modular rack (Ver. 2.010 and later)

• S-0808 8x8 I/O UNIT

• S-4000M REAC MERGE UNIT

Basic knowledge about REAC

About REAC

The REAC (Roland Ethernet Audio Communication) interface is
the core of this system. It uses a proprietary protocol based on
Ethernet technology, and allows 40 channels of digital audio to
be sent in each direction via a single Cat5e Ethernet cable.

REAC can do the following:

• Send 40 channels of digital audio in each direction

• Send audio up to 100 meters on one Cat5e cable

• A switching hub or the S-OPT option can be used to extend
the cable.

• Use a switching hub to easily split the signal

• The transmission delay between REAC devices is extremely
small (approximately 375 microseconds)

When the signal passes through a switching hub, there will be
approximately 200 microseconds of delay for each unit.

About cables

Since Cat5e Ethernet cables are used, it’s very easy to connect
REAC devices to each other. Cat5e Ethernet cables are commonly
used for computer network connections, and have RJ45 plugs.

Types of Ethernet cable

There are two types of Ethernet cables. Although both types have
the same exterior appearance, their RJ45 plugs are wired
differently, as follows:

Introduction

The REAC port on the M-480 does not support REAC EMBEDDED
POWER. When you connect an S-0808, install an external battery
on the S-0808 to power via the DC IN port. Note, however, that
when the connection on the M-480 is made via an S-4000M or S­4000D, the S-0808 is powered by the S-4000M or S-4000D, and
so no external battery is needed.

In this manual, we may abbreviate these units as the S-1608, S­0816, or S-4000S, or may refer to them collectively as input/
output units.

Text enclosed in square brackets [ ] indicates a button. For
example, the direction to “press [METER]” means that you are to
press the METER button.

If a secondary name is shown for a button, such as [DISP (BUTTON
ASSIGN)], the text in parentheses indicates the function that the
button has when pressed while holding down [SHIFT].

In the case of function buttons, the function is given in
parentheses, such as [F1 (LINK)].

• Crossover cable

The internal wiring of the cable is crossed at each RJ45 plug.
This means that the connections of the RJ45 plugs will differ
at each end of the cable.

• Straight cable

The internal wiring of the cable is the same at each end.

Crossover cables (such as Roland SC-W20F, Roland SC-W100S, or
Roland W100S-R) should be used when connecting to the REAC
ports on this product.

Certain cautions apply if you’re using a conventional switching
hub with this system. For details, refer to “REAC applications” (p.

142).

Ethernet connectors

Ethernet cables use RJ45 plugs. REAC equipment provides an
RJ45 connector for each REAC port.

fig.RJ45andREAC-j.eps

Introduction

RJ45 plug

For critically important communication, it is vital to protect the
RJ45 plug and connector. For such situations, REAC RJ45
connectors use a sturdy Neutrik EtherCon plug. Using the
EtherCon RJ45 plug allows a latched-type connector similar to an
XLR plug.

The Neutrik Corporation provides EtherCon RJ45 plugs, as well as
EtherCon plugs that can be added to the RJ45 plug of
commercially available Ethernet cable.

The RJ45 connectors of REAC ports can accept either RJ45 plugs
or EtherCon plugs.

Cautions for handling Cat5e cables

• Do not apply excessive force to Cat5e cables.

• Do not bundle (bend) a Cat5e cable to a radius less than 25
mm, or fold it in two.

• Do not tightly bundle a Cat5e cable.

• Do not place multiple Cat5e cables in parallel for an
extended distance.

• Do not place Cat5e cables near a source of electrical noise
(power supply cord, motor, fluorescent lights, etc.).

REAC connections

Here is a typical example of connections using the S-1608.

When connecting REAC devices to each other, the REAC mode of
one device must be set to REAC master, and the REAC mode of
the other must be set to REAC slave.

In this system, the M-480 is normally set to be the master (FOH
setting), while the input/output units are set to be slaves.

For a more detailed description of connections, refer to “REAC
applications” (p. 142).

OUT9–40 CH1–32 DIRECT OUTS

You can change the input/output settings. For details, refer to
“Input/output patchbay” (p. 86).

Cautions when making REAC connections

• REAC connections are designed so that noise will not be
produced even if you hot-swap (plug or unplug a live
connection). However in rare cases, noise may occur at the
audio output of the system. To prevent hot-swapping from
causing damage to your speakers or other equipment
connected to the audio outputs, please observe the
following points:

• Make REAC connections while holding down the [MUTE ALL
OUTPUTS] of the input/output unit

• Before you make REAC connections, mute the outputs using
[F6 (MUTE ALL OUT)] in the MUTE GROUP screen (p. 114).

Cat5e Ethernet cables up to 100 meters long are supported. If
you need a longer connection, we recommend that you use the
optional S-OPT.

14

In some cases, the muted state will continue even after you
release your finger from [MUTE ALL OUTPUTS] of the input/
output unit. In this case, press [MUTE ALL OUTPUTS] once again
to mute, and then release your finger to unmute the unit.

Placement

Introduction

Attaching the ferrite core

Before using the M-480, you must attach the ferrite cores to the

Ethernet cable or coaxial cable. This is for the purpose of

preventing electromagnetic noise; do not remove it.
