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.

8. Ventilation - The appliance should be situated so that its location or position dose not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.
9. Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.
10. Power Sources - The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.
11. Grounding or Polarization - The precautions that should be taken so that the grounding or polarization means of an appliance is not defeated.
CAUTION:
TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
ATTENTION:
POUR EVITER LES CHOCS ELECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU' AU FOND.
The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
12. Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
13. Cleaning - The appliance should be cleaned only as recommended by the manufacturer.
14. Nonuse Periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.
15. Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.
16. Damage Requiring Service - The appliance should be serviced by qualified service personnel when:
A. The power supply cord or the plug has been damaged; or B. Objects have fallen, or liquid has been spilled into the appliance;
or C. The appliance has been exposed to rain; or D. The appliance does not appear to operate normally or
exhibits a marked change in performance; or E. The appliance has been dropped, or the enclosure damaged.

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 purchas­ing 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 RM­2 is automatically muted, while you can manually mute it whenever you want. See page 6 for details.

"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 switc h the input. (3) When the unit does not lock to the external digital cloc k while selecting the digital input.
<Note>:
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.
When you turn on the power, both the user mute and system mute functions are
