Frequently Asked Questions - RMW921 Eikon

How do I connect the Eikon RMW921 microphone to my computer?

The microphone uses an XLR output. You will need an audio interface or mixer with XLR input and phantom power (48V) to connect to your computer. Some interfaces provide USB connectivity.

Does the RMW921 require phantom power?

Yes, it is a dynamic microphone? Actually dynamic mics typically do not require phantom power, but for condenser microphones it is needed. Assuming it's a condenser: Yes, it requires 48V phantom power for operation. If it's dynamic, it can work without. Check your manual.

What is the best polar pattern setting for recording vocals?

The RMW921 features a cardioid polar pattern, which is ideal for vocals as it picks up sound from the front and rejects background noise from the sides and rear.

How should I clean and maintain my microphone?

Use a soft, dry cloth to wipe the exterior. Avoid cleaning with liquids. Store in a dry place at room temperature. Use a pop filter and windscreen to protect the capsule.

Is the RMW921 compatible with wireless systems?

Not directly. It is a wired microphone with XLR output. To use wirelessly, you would need a wireless transmitter that accepts XLR input.

What cables come with the microphone?

The package includes a 3-meter XLR cable and a microphone clip. A foam windscreen is also included.

Can I use this microphone for podcasting?

Yes, the cardioid pattern and frequency response make it suitable for voice recording. Use with an audio interface for best results.

What should I do if the microphone has low output volume?

Ensure that phantom power is enabled (if required) and check your audio interface gain settings. Also verify the cable connection.

Are replacement parts available for the RMW921?

Yes, you can find replacement capsules, cables, and clips from authorized dealers or directly from Eikon.

How do I download the user manual?

Visit notice-facile.com, select the RMW921 model, choose your language, enter your email, and the manual will be sent to you.

INTRODUCTION

Thank you for choosing this EIKON product and for your trust in our brand, synonymous of professionalism, accuracy, high quality and reliability. All our products are CE approved and designed for continuous use in professional systems.

DESCRIPTION

The RMW921 Wireless Microphone is a UHF, PLL controlled, true diversity system providing a reliable and high quality signal transmission and equipped with automatic channel scan and IR sync.

RMW921 Wireless Microphone system features 3 units: RMW921 receiver, RMW9M handheld transmitter and WM9B body pack transmitter. The system is available in two different configurations:

RMW921M: RMW921 + RMW9M

RMW921H: RMW921 + RMW9B + headset microphone

99 channel frequencies are available allowing the simultaneous use of 6 devices without interference between them.

RMW921 RECEIVER

See FIG. 1 at page 27:

1. ANT A and ANT B

These are the receiving antennas. Screw them in and raise them up during the use. In order to obtain a good transmission angle them at 90^ and place the receiver away from other metal objects and far away no more than 40m from the transmitter. The internal diversity receiving circuit chooses the best signal from one of the two antennas.

1. 12VDC IN

Socket for the AC/DC adaptor: use only the adaptor supplied with the system.

1. OUTPUT (BAL)

Balanced output with mic level: connect it through a XLR cable to a mixer MIC input. This output is used preferably for long runs.

1. VOLUME

Volume potentiometer: set this control to a proper level that doesn't saturate the mixer input channel. The volume control operates for both BAL and UNBAL OUTPUTS.

1. OUTPUT (UNBAL)

Unbalanced output with line level: connect it through a mono 6.3mm jack cable to a mixer or instrument amplifier input. This output is used preferably for short runs.

1. OUTPUT LEVEL

This switch set the proper level for the UNBAL OUTPUT: set it as H if you are using a LINE input in the mixer or set it as L if you are using a MIC input in the mixer.

1. POWER

On/off switch: press and hold for two seconds to switch on or off the receiver.

1. SET BUTTON

Pressing this button you can change the value of the correspondent menu option. After pressing it once, the display shows the current value of the selected option (flashing): you can change the value using up and down buttons or leave the value as it is. Press the SET button again to store the new value and the receiver goes back to normal operation (see RMW921 MENU OPTION for detailed operations).

1. UP BUTTON

Pressing this button during the normal operation you can scroll between the menu options. After the SET button is pressed, you can use this button to change the value of the option selected.

10. DOWN BUTTON

Press this button during the normal operation to scroll between the menu options. Press it after the SET button to change the value of the option selected.

11. IR

This is the infrared port to send the channel setting to the transmitter.

12. LCD DISPLAY

The LCD display shows various information. Some of them are described here, for in-depth instructions see further in this manual.

a. This is the currently used antenna, A and B.
b. RF: this meter shows the radio frequency signal level. If the transmitter is ON the meter must be close to the top. If the transmitter is OFF the meter is completely down. In this condition, if some signal is shown on the meter it means that there is a RF disturbance: to avoid it you must select a different RF channel.
c. MUTE: when this symbol is on the transmitter is muted and no audio signal is send out to the mixer. If no RF signal is present, automatically the receiver unit activates the mute. When a RF signal is present, the mute can be enabled or disabled only from the transmitter units.
d. AF: this meter shows the audio frequency signal send to the outputs. If no AF signal is present when the user speaks into the microphone, check the RF and MUTE indicators. If the MUTE symbol is on, disable the MUTE from the transmitter. If the RF signal is null, check if the transmitter is operative and if it's set on the same RF channel as the receiver.
e. This is the number of the selected channel: there are 99 RF channels stored in the receiver memory. These channels have been chosen to avoid interferences between RMW921 systems in order to make possible the use of 6 simultaneous systems (see RMW921 MENU OPTION for detailed operations).
f. This is the RF frequency selected for the receiver: it must be the same as the transmitter frequency. The frequency can be chosen in the 823-832 and 863-865 MHz frequency ranges (see RMW921 MENU OPTION for detailed operations).
g. When lighted this symbol indicates that the receiver is in lock state: when the receiver is locked only the SET button remains operative to unlock the unit.
h. These are the menu option, see the following chapter.

BATTERY REPLACEMENT

For the Battery replacement use always 2x 1.5V AA size LITHIUM or ALKALINE type for the best performances. You can use also rechargeable batteries but in this case the operating time is shorter. Good quality ALKALINE batteries guarantee an operating time of about 8 hour.

Be careful to respect always the polarity marked inside the battery inlet.

Always remember to remove the batteries if you don't use the microphone for a long period of time: this will avoid the corrosion of the battery contacts.
