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.
Ricevitore Bodypack
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.

Istruzioni per l'uso
Accensione e associazione
- Turn on the transmitter by pressing the power button. The display will illuminate, showing the current channel and frequency.
- Turn on the bodypack receiver by rotating the volume knob clockwise. The display will show the current channel and frequency.
- 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 SINCRONIZZAZIONE 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.
Regolazione del volume e monitoraggio
- 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.
Selezione della frequenza
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.
Risoluzione dei problemi
No Audio from Receiver
- Controllo dell'alimentazione: Assicurarsi che sia il trasmettitore che il ricevitore siano accesi.
- Controllo della batteria: Verify that the receiver has fresh AA batteries and they are inserted with correct polarity.
- Sorgente audio: Confirm that the transmitter is receiving an audio signal from your connected source (e.g., mixer).
- Stato di associazione: Check if the receiver is successfully paired with the transmitter (the RF indicator on the receiver should be lit). Re-sync if necessary.
- Livelli del volume: Ensure the volume levels on both the transmitter's monitoring interface and the bodypack receiver are turned up.
- Collegamento auricolari: Make sure the earbuds are properly connected to the receiver's headphone jack.
Signal Dropouts or Interference
- Distanza operativa: Ensure the transmitter and receiver are within the specified operating distance of 150-200 ft (45-60 meters).
- Selezione canale: 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.
- Linea di vista: Ridurre al minimo gli ostacoli fisici tra il trasmettitore e il ricevitore.
