1. Водич за подешавање
This section provides instructions for the initial setup of your CAD Audio GXLIEM4 system.
1.1 Распакивање и почетни преглед
Carefully unpack all components and verify that all items are present and undamaged. The system includes:
- GXLIEM4 Quad Mix Transmitter Base Station
- 4 GXLIEM Bodypack Receivers
- 4 MEB1 High-Performance Earbuds
- Rack Mount Ears and Hardware
- Antenna Relocation Kit
- Повер Адаптер

1.2 Инсталација предајника
- Монтажа на рацк: Attach the included rack mount ears to the sides of the GXLIEM4 transmitter using the provided screws. Secure the transmitter into a standard 19-inch equipment rack.
- Антенска веза: Connect the two included antennas to the BNC connectors labeled 'ANT A+B' and 'ANT C+D' on the rear panel of the transmitter. For optimal reception, ensure antennas are positioned vertically and unobstructed. An antenna relocation kit is provided for remote antenna placement if needed.
- Аудио улаз: Connect your audio mixer's auxiliary outputs to the corresponding input jacks (Input A, Input B, Input C, Input D) on the rear of the GXLIEM4 transmitter. Each input corresponds to a discrete mix for a bodypack receiver.
- Прикључак за напајање: Connect the power adapter to the 'DC INPUT 13-18V/300mA' jack on the rear panel and plug it into a suitable power outlet.

1.3 Подешавање пријемника за тело
- Инсталација батерије: Open the battery compartment on the back of each bodypack receiver. Insert two AA batteries, observing the correct polarity (+/-). Close the compartment securely. The bodypack receivers are designed for standard AA alkaline batteries.
- Повезивање слушалица: Plug the MEB1 earbuds into the 3.5mm headphone jack on the top of the bodypack receiver. Ensure a secure connection.

2. Упутство за употребу
This section details the operational procedures for your GXLIEM4 system.
2.1 Укључивање/искључивање
- предајник: Flip the power switch on the front right panel of the GXLIEM4 transmitter to the 'ON' position. The display for each channel will illuminate.
- Пријемник за тело: Rotate the volume knob on the top of the bodypack receiver clockwise until the display illuminates. Continue rotating to adjust the volume.

2.2 Frequency Selection and Synchronization
The GXLIEM4 system operates in the 900 MHz band, offering frequency agile performance to avoid interference.
- Selecting a Frequency: On the desired transmitter channel, use the 'DOWN' and 'UP' buttons to navigate through available frequencies. Observe the 'AF' (Audio Frequency) and 'RF' (Radio Frequency) indicators. A clear channel will show stable RF.
- IR Synchronization: Once a frequency is selected on the transmitter, align the IR sensor on the bodypack receiver (located near the battery compartment) with the 'IR' window on the corresponding transmitter channel. Press and hold the 'IR' button on the transmitter until the bodypack receiver's display updates with the new frequency. This synchronizes the bodypack to the transmitter channel.
2.3 Adjusting Mixes and Volume
- Transmitter Mix Level: The audio input level for each channel is controlled by your external audio mixer. Ensure appropriate signal levels are sent to the GXLIEM4 inputs.
- Bodypack Receiver Volume: Use the 'VOL' knob on the bodypack receiver to adjust the personal monitoring volume to a comfortable listening level.
2.4 Earbud Usage
Insert the MEB1 earbuds comfortably into your ears. Proper fit is crucial for optimal sound isolation and bass response. Experiment with different ear tip sizes if provided to find the best seal.
3. Одржавање
Regular maintenance ensures the longevity and optimal performance of your GXLIEM4 system.
3.1 Чишћење
- Transmitter and Receivers: Wipe surfaces with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Еарбудс: Clean ear tips regularly with a damp крпом. Уверите се да су потпуно суви пре него што их поново причврстите.
3.2 Замена батерије
The bodypack receivers provide over 10 hours of battery life with fresh AA alkaline batteries. Replace batteries when the low battery indicator appears on the bodypack display to prevent unexpected power loss during use.
3.3 Складиштење
When not in use, store the system in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries from bodypack receivers if storing for extended periods to prevent leakage.
КСНУМКС. Решавање проблема
This section addresses common issues you might encounter with your GXLIEM4 system.
| Проблем | Могући узрок | Решење |
|---|---|---|
| No audio from bodypack receiver | Low/dead batteries; incorrect frequency; disconnected earbuds; transmitter not powered on; no audio input to transmitter. | Replace batteries; resynchronize frequency; check earbud connection; ensure transmitter is powered; verify audio input from mixer. |
| Interference or dropouts | Conflicting frequencies; excessive distance from transmitter; obstructions; low battery. | Scan for a clear frequency and resync; reduce distance to transmitter; ensure line of sight; replace bodypack batteries. The 900 MHz band is generally less susceptible to TV/FCC interference. |
| Short battery life on bodypack | Old or low-quality batteries; high volume settings. | Use fresh, high-quality alkaline AA batteries. Reduce volume if possible. |
| Bodypack not syncing with transmitter | IR sensors not aligned; IR button not pressed long enough; transmitter channel not active. | Ensure direct line of sight between IR sensors; press and hold IR button until sync is confirmed; verify transmitter channel is powered and active. |
