INTRODUCTION
Thank you for choosing this PROEL 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 RMW821 Wireless Microphone is a UH F, PLL controlled, true diversity system providing a reliable and
high quality signal transmission and equipped with automatic channel scan and IR sync.
RMW821 W ireless Microphone system features 3 units: RMW821 receiver, RMW8M handheld transmitter
and WM8B body pack transmitter. The system is available in two different configurations:
RMW821M: RMW821 + RMW8M
RMW821H: RMW821 + RMW8B + headset microphone
99 channel frequencies are available allowing the simultaneous use of 6 devices without interference
between them.
RMW821 RECEIVER
See FIG. 1 at page 27:
1. ANT 1 and ANT 2
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 50m from the transmitter. The internal diversity receiving circuit chooses the best signal
from one of the two antenna.
2. 12VDC IN
Socket for the AC/DC adaptor: use only the adaptor supplied with the system.
3. 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.
4. 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.
5. 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.
6. 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.
7. POWER
On/off switch: press and hold for two seconds to switch on or off the receiver.
8. 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 RMW821 MENU OPTION for detailed operations).
9. 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.
7
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 is ANT 1 and B is ANT 2.
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 RMW821 systems in order to make
possible the use of 6 simultaneous systems (see RMW821 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 821-832 and 863-865 MHz frequency ranges (see RMW821
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.
