Product Overview

Transmitter (G-MARK G5.1 IEM)

The transmitter unit is the central hub of your monitoring system, responsible for broadcasting the audio signal to the bodypack receivers. It features a clear display for monitoring channel and frequency, along with controls for system configuration.

The transmitter features a display screen, control buttons for frequency modulation and sync, a power on/off button, a monitoring interface with volume control, and AF IN (R/L) inputs on the rear panel, along with antenna sockets and power input.

Bodypack Receiver

The bodypack receiver is a compact, portable unit that receives the audio signal from the transmitter and delivers it to your in-ear earbuds. It is powered by AA batteries and includes a volume control for personal adjustment.

The bodypack receiver includes a power switch and volume knob, a low battery indicator, and an RF signal indicator. It is designed for portability and personal monitoring.

Setup Instructions

Connecting the Transmitter

1. Connect the power adapter to the transmitter's DC IN (12V-18V) port and then to a power outlet.
2. Attach the included antenna to the ANTENNA socket on the rear of the transmitter.
3. Connect your audio source (e.g., mixing console, audio mixer) to the AF IN (R) and AF IN (L) inputs on the transmitter. Use the provided 6.35mm audio cable or XLR cables (not included) as appropriate for your setup.

Preparing the Bodypack Receiver

1. Open the battery compartment on the back of the bodypack receiver.
2. Insert two AA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment securely.
4. Connect the in-ear earbuds to the 3.5mm headphone jack on the bodypack receiver.

Operating Instructions

Powering On and Pairing

1. Turn on the transmitter by pressing the power button. The display will illuminate, showing the current channel and frequency.
2. Turn on the bodypack receiver by rotating the volume knob clockwise. The display will show the current channel and frequency.
3. To pair the receiver with the transmitter, ensure both devices are powered on. On the transmitter, use the frequency modulation buttons to select a desired channel. Press the SYNC button on the transmitter. Hold the bodypack receiver close to the transmitter's SYNC area (usually near the display) until the RF indicator on the receiver lights up, indicating a successful connection.

Adjusting Volume and Monitoring

• Adjust the monitoring volume for your earbuds using the volume knob on the bodypack receiver.
• The transmitter also features a front listener interface with an independent volume adjustment knob for direct monitoring.

Frequency Selection

The G5.1IEM system operates in the UHF band of 550 MHz to 580 MHz, offering 40 available channels. If you encounter signal interference, use the frequency modulation buttons on the transmitter to select a different, clearer channel. The system supports setting and storing multiple groups of preset frequencies.

The transmitter's display provides real-time information on UHF signal strength, channel, and frequency, allowing for precise adjustments.

Troubleshooting

No Audio from Receiver

• Power Check: Ensure both the transmitter and receiver are powered on.
• Battery Check: Verify that the receiver has fresh AA batteries and they are inserted with correct polarity.
• Audio Source: Confirm that the transmitter is receiving an audio signal from your connected source (e.g., mixer).
• Pairing Status: Check if the receiver is successfully paired with the transmitter (the RF indicator on the receiver should be lit). Re-sync if necessary.
• Volume Levels: Ensure the volume levels on both the transmitter's monitoring interface and the bodypack receiver are turned up.
• Earbud Connection: Make sure the earbuds are properly connected to the receiver's headphone jack.

Signal Dropouts or Interference

• Operating Distance: Ensure the transmitter and receiver are within the specified operating distance of 150-200 ft (45-60 meters).
• Channel Selection: Change the operating channel on the transmitter using the frequency modulation buttons to find a clearer frequency. The system offers 40 channels to choose from.
• Line of Sight: Minimize physical obstructions between the transmitter and receiver.
• External Interference: Check for other wireless devices operating in the same UHF frequency band that might be causing interference.
