Introduction

The AtlasIED MWRCVR wireless receiver is the ideal choice for a variety of applications ranging

from classrooms and conference rooms to lecture halls and live presentations. Designed to

work in conjunction with either the MWHHM wireless handheld microphone or the MWBTP

wireless belt pack microphone, the MWRCVR allows for great flexibility in sound reinforcement

applications. With the ability to connect to a variety of devices via the included balanced XLR

or unbalanced line output the MWRCVR can be used with a variety of amplifiers or mixers to

address the needs of any installation. Multiple units can be used in a single installation since

the unit receives transmission via the UHF frequency band and pairs to individual MWHHM or

MWBTP on available channels. The unit can be used as a standalone piece on a shelf or desk

or it can be rack mounted by itself or with a second MWRCVR using the rack mount kit, model

MWRMK (sold separately).

Key Features

• Multi-function LCD display for channel / frequency, volume level, and signal strength

• Patented technology for 2-way data transfer between transmitter and receiver

• 100 frequencies available through the 25MHz signal band

• Dual antennas reduce distortion

• IR sensor for connection to wireless microphone

• Selectable mic or line output

Applications

• Classrooms

• Conference Rooms

• Lecture Halls

• Live Presentation

Changing Channel / Frequency

1. Press and release SET button until the CHANNEL | FREQUENCY page appears (Fig 1).

2. Press UP or DOWN button to select a new channel. As the channel changes, the frequency

changes accordingly (Fig 2).

3. After a channel is chosen, wait 5 seconds to store the setting.

Synchronizing Channels on the Receiver and Transmitter

Align infrared areas of the receiver and microphone within 12" (30cm).

A. Changing the receiver’s channel

1. Press the synchronizing button on the microphone (Fig 4).

2. The microphone’s LED will illuminate, indicating the frequency is being transmitted to the

receiver and that the receiver is synchronizing channels with the microphone (Fig 5).

3. “COPIED BY IRDA” will appear on the receiver’s LCD, indicating that the receiver has been

successfully synchronized (Fig 6).

B. Changing the microphone’s channel

1. Press the synchronizing button on the receiver (Fig 7).

2. “IRDA DATA SEND” will appear on the receiver’s display (Fig 8).

3. “IRDA TX FINISH” will appear to denote data transferred (Fig 9).

If this does not synchronize the channels, ensure the IR sensor panels are properly aligned and

are located within 12" (30cm) of each other and try synchronizing again.

Channel Scanning

For an interference-free operation, a cleaner channel might be necessary if the current one

receives too much interference. Before scanning, the transmitter must be switched off.

1. Press and release SET button until the AUTO SCAN page appears (Fig 10).

2. Press UP or DOWN button to find and locate a clear, interference-free channel (Fig 11).

3. After a channel is chosen, wait 5 seconds to store the setting.

Adjusting Volume Level

1. Volume adjustment can be made from the home screen (Fig 12).

2. Press UP or DOWN button to choose a new level (Fig 13).

3. After the level is adjusted, wait 5 seconds to store the setting.

Adjusting Squelch Level

When interference is encountered try reducing the sensitivity of the receiver, thus less

susceptible to interference.

1. Press and release SET button until the SQUELCH SETUP page appears (Fig 14).

2. Press UP or DOWN button to choose a new level between 1 and 10 (Fig 15).

3. After the level is adjusted, wait 5 seconds to store the setting.

Since increasing the squelch level will also reduce the reception distance, it’s recommended

to choose the lowest level that can eliminate the interference. If this still does not solve the

problem it means this frequency is not suitable. Adjust the squelch back to its preset level and

use the scan function to locate a clear, interference-free channel.

Audio Output Connection

Balanced Output: XLR connector provides balanced audio output signal from this jack to the

mixer / amplifier. Use an audio output cable with “XLR” or “Cannon” connector, connect one

end to the balanced output jack of the receiver, and the other end to the “LINE IN” or “MIC

IN” jack of the mixer / amplifier.

Level Switch Setting: When connecting to the LINE / AUX IN of a mixer / amplifier, switch to

“LINE” position (Fig 16). DO NOT use the “MIC” position as they may not deliver a sufficient

output level. When connecting to the “MIC IN” jack of a mixer / amplifier, switch to “MIC”

position (Fig 17). Distortion may occur at the wrong level position.

Audio Output Connection

Unbalanced Output: 1/4" line output connector provides unbalanced audio output signal from

this jack to the mixer / amplifier. Use an audio output cable with 1/4" PHONE PLUG connector.

Connect one end from the unbalanced output jack of the receiver, and the other end to the

“LINE IN” or “MIC IN” jack of the mixer / amplifier.

Level Switch Setting: When connecting to the LINE / AUX IN of a mixer / amplifier, switch to

“LINE” position (Fig 18). DO NOT use the “MIC” position as they may not deliver a sufficient

output level. When connecting to the “MIC IN” jack of a mixer / amplifier, switch to “MIC”

position (Fig 19). Distortion may occur at the wrong level position.

Receiver Installation

1. For best operation, the receiver should be at least 1m above the ground and 1m away from

a wall or metal surface to minimize reflections.

2. The transmitter should also be at least 1m away from a wall or metal surface to minimize

reflections. The microphone should also be at least 1m away from the receiver.

3. Keep antennas away from noise source such as motors, automobiles, neon light as well as

large metal objects.

Rack Mounting

The receiver can be cabinet-mounted by either one or two units. If only one receiver is to be

mounted, an optional kit is available (Fig 21). If two receivers are to be mounted, they can be

assembled by another kit (Fig 22).
