Introduction
Thank you very much for purchasing the Fostex Model RM-2.
The Model RM-2 is a rack-mountable powered monitor system which allows
you to monitor digital or analog audio signals.
It incorporates a 10 W x 2 power amplifier and outputs signals from the inter-
nal speakers (or from the headphones output jack). You can check the input
level via the 26-dot LED meters.
Read this owner's manual thoroughly before using. We hope you will use the
RM-2 for a long time.

Important Safety Instructions
1)
2)
3)
4)
5)
6)
7)
Read these instructions.
Keep these instructions.
Heed all warnings.
11) Only use attachments/accessories
specified by the manufacturer.
12) Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the apparatus.
When a cart is used, use caution when
moving the cart/apparatus combination
to avoid injury from tip-over.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings.
Install in accordance with the
manufacturer's instructions.
8)
9)
Do not install near any heat sources such
as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that
produce heat.
13) Unplug this apparatus during lightning
storms or when unused for long periods
of time.
14) Refer all servicing to qualified service
personnel. Servicing is required when the
apparatus has been damaged in any
way, such as power-supply cord or plug
is damaged, liquid has been spilled or
objects have fallen into the apparatus, the
apparatus has been exposed to rain or
moisture, does not operate normally, or
has been dropped.
Do not defeat the safety purpose of the
polarized or grounding-type plug.
A polarized plug has two blades with one
wider than the other. A grounding type
plug has two blades and a third grounding
prong. The wide blade or the third prong
are provided for your safety.
If the provided plug does not fit into your
outlet, consult an electrician for
replacement of the obsolete outlet.
10) Protect the power cord from being walked
on or pinched particularly at plugs,
convenience receptacles, and the point
where they exit from the apparatus.

Names and functions
After turning on the power
Each time you turn on the power, the RM-2 is muted and the "MUTE" indicator flashes. (Figure 1 below
shows the condition of the status information section when you first turn on the power after purchas-
ing the RM-2.)
To use the RM-2, therefore, press the [CH SEL] key to unmute the RM-2 (see Figure 2 below).
The "MUTE" indicator turns off. In particular conditions, the system mute function works and the RM-
2 is automatically muted, while you can manually mute it whenever you want. See page 6 for details.

6) Monitor output level controls
These dual concentric controls adjust the
speaker output (or headphones output) levels.
The outer control adjusts the left channel level,
while the inner control adjusts the right
channel level.
By long press of the [CH SEL] key, you can mute
the unit, while the [MUTE] indicator flashes (this
is called "user mute"). Pressing the [CH SEL] key
again release muting and the [MUTE] indicator
turns off. See page 6 for the user mute func-
tion.
7) PHONES jack
This jack is used for connecting headphones.
When a plug is inserted, the internal speakers
are cut.

"System mute" and "user mute"
The RM-2 has two mute functions. One is the "user mute" function which allows you to manually
mute the unit whenever you want, while the other is the "system mute" function which automatically
mute the unit in particular conditions.
User mute: The user mute function allows you to mute the unit manually by pressing and hold-
ing down the [CH SEL] key until the [MUTE] indicator lights up (the level meters show the input
levels regardless of the mute condition). You can release muting by pressing the [CH SEL] key
briefly.
System mute: The RM-2 is automatically muted in any of conditions (1) through (3) below (un-
like the user mute, the level meters do not show the input levels in this case). The system mute
function is activated to prevent the noise from being generated from the speaker units. In the
cases of (1) and (2) below, muting is released after a few seconds. In the case of (3), muting is
released when the unit locks to the external digital signal.
(1) When you turn on the power.
(2) When you press the [INPUT] switch to switch the input.
(3) When the unit does not lock to the external digital clock while selecting the digital input.
<Note>: When you turn on the power, both the user mute and system mute functions are
activated. Therefore, system muting is automatically released after a few seconds but user
muting is not released automatically. So you have to press the [CH SEL] key to release user
muting.
The MUTE indicator shows mute status. When the system mute is active, the MUTE indicator is lit.
When the user mute is active, the MUTE indicator flashes. As the user mute status takes priority to
the system mute status, the MUTE indicator shows the status as follows.
