Frequently Asked Questions - RM-2 FOSTEX

How do I unmute the RM-2 after turning it on?

Press the [CH SEL] key briefly. The MUTE indicator will turn off and audio will be heard.

How do I select between analog and digital inputs?

Use the [INPUT] switch on the front panel. Set to ANALOG for analog signals or DIGITAL for AES/EBU digital signals.

Can I monitor only the left or right channel?

Yes. Press the [CH SEL] key repeatedly to cycle through: Stereo, Mono (L+R), Mono (L only), Mono (R only). The current selection is shown by indicators in the status section.

How do I use headphones with the RM-2?

Plug headphones into the PHONES jack (1/4" stereo). When inserted, the internal speakers are automatically cut off. Use the dual concentric monitor output controls to adjust volume.

What does the 'system mute' function do?

The system mutes automatically in three conditions: (1) at power-on, (2) when switching input, and (3) when the digital input loses lock. Muting is released after a few seconds or when lock is regained.

How can I manually mute the RM-2?

Press and hold the [CH SEL] key until the MUTE indicator starts flashing. This activates user mute. Press the key briefly to unmute.

What is the difference between the peak and VU metering modes?

When digital input is selected, the meters use peak metering (0 dB = 0 dBFS). When analog is selected, they use VU metering (0 dB = +4 dBu or -10 dBV). Peak values are held for three seconds in digital mode.

What power cord is required for my region?

For US/Canada: 120 VAC 60 Hz. For Europe: 230-240 VAC 50/60 Hz. Use the supplied power cord and ensure the voltage matches your outlet.

How should I clean the RM-2?

Clean only with a dry cloth. Do not use any liquids or sprays. Refer to the safety instructions for more details.

What should I do if the RM-2 does not power on?

First, check that the power cord is securely connected to both the unit and the AC outlet. Verify the outlet is working. If the problem persists, consult qualified service personnel; do not attempt internal repairs.

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 RM-2 is automatically muted, while you can manually mute it whenever you want. See page 6 for details.

1) Internal speakers

2) LED level meters

These meters show the input levels of digital or analog input signals.

When the [INPUT] switch is set to DIGITAL	The levels of digital input signals are shown by peak metering. The peak value is hold for three seconds.
When the [INPUT] switch is set to ANALOG	The levels of analog input signals are shown by VU metering. The peak value is hold.
When digital input is selected: Peak metering, 0 dB: 0dBFS When analog input is selected: VU metering, 0dB: +4 dBu/-10 dBV

3) Status information section

This section indicates the status of the [CH SEL] key and [INPUT] switch, as well as mute on/off status. See page 6 for details.

4) [INPUT] (input select) switch

This switch selects the input signal between analog and digital.

ANALOG(□)	You can monitor the analog signals received via the [ANALOG INPUT] connectors.
DIGITAL(□)	You can monitor the digital signal received via the [DIGITAL INPUT] connectors. When the unit receives a correct digital signal and works correctly, the "DIGITAL" indicator in the status information section lights. When the unit does not receive a correct digital signal or does not work correctly, the "DIGITAL" indicator flashes.

: When switching the input signal (between analog and digital), the system mute function works and unit is automatically muted for a while (the [MUTE] indicator lights). This prevents the noise from being generated from the speaker units when switching the signal. Muting is automatically released after a few seconds. See page 6 for details about the system mute function.

5) [CH SEL] (channel select) key

This key switches the channel(s) to be monitored.

Each press of the key switches the channel(s) in the following order (by default when turning on the power, "stereo" is selected).

The current selection is shown by the indicators in the status information section (see page 6 for the indication of channel selection).

graph TD
    A["Stereo"] --> B["Mono (L+R)"]
    B --> C["Mono (L only)"]
    C --> D["Mono (R only)"]
    D --> A

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 function.

The following shows which signal is output from each internal speaker unit for each channel selection.

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.

7) PHONES jack

This jack is used for connecting headphones. When a plug is inserted, the internal speakers are cut.

8) [ANALOG INPUT] connectors (XLR / 1/4" combi-jacks)

You can connect an XLR-3-12C connector or 1/4" plug to each of these combi-jack type [ANALOG INPUT] connectors (you cannot insert both together). Each connector accepts a +4 dBu analog signal via XLR connection or a -10 dBV analog signal via 1/4" connection.

	HOT (+)	COLD (-)	Ground
XLR	Pin 2	Pin 3	Pin 1

9) [DIGITAL INPUT] connector (XLR connector)

This connector accepts an AES/EBU digital signal at the sampling frequency within the 44.1 kHz to 96 kHz range. You can connect an XLR-3-12C connector.

	HOT (+)	COLD (-)	Ground
XLR	Pin 2	Pin 3	Pin 1

10) [POWER] switch

This switch turns the power on or off. Each time you turn on the power, the RM-2 is muted for preventing the noise from being generated from the speaker units (the "MUTE" indicator flashes).

11) [AC IN] connector

Connect to the AC outlet using the supplied power cord. Make sure that the AC outlet voltage matches the unit.

Indication of channel selection

You can see which channel(s) is/are now selected by the [CH SEL] key via the status information section, as below.

"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 holding 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 (unlike 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.

: 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.

		System mute
		OFF	ON
User mute	OFF	Unlit Lit
	ON	Flashing	Flashing
