Setup
1. Battery Installation
- Unscrew the lower part of the transmitter body to access the battery compartment.
- Insert two (2) AA alkaline batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Securely screw the lower part of the transmitter body back into place.

- Gently screw the microphone head onto the transmitter until it is firmly seated. Do not overtighten.
3. Powering On/Off
Locate the power button on the transmitter. Press and hold the power button for a few seconds to turn the unit on or off. The display will illuminate upon power-on.
4. Synchronization with Receiver
For wireless operation, the HT4500 must be synchronized with a compatible AKG wireless receiver. Refer to your receiver's manual for detailed synchronization instructions. Generally, this involves:
- Setting the receiver to scan for available frequencies.
- Initiating the synchronization process on the transmitter (e.g., via infrared or manual frequency setting).
- Confirming successful pairing on both the transmitter and receiver displays.
Operating Instructions
Basic Operation
- Mute Function: The transmitter features a mute switch. Activate it to temporarily silence the microphone output without powering down the unit.
- Display Information: The integrated display shows critical information such as the selected frequency, channel, and remaining battery life in hours. This real-time display helps in managing operational time effectively.
Transmission Power
The HT4500 offers up to 50mW transmission power, ensuring robust radio signal strength for long-distance applications and reliable performance in challenging RF environments. Adjusting transmission power may be possible via the transmitter's menu or in conjunction with the receiver, depending on local regulations and operational needs.
Antenna Technology
The unique dipole-antenna design of the HT4500 ensures reliable transmission even when one pole of the antenna is partially or completely covered by the user's hand, minimizing signal dropouts during performance.
Maintenance
Cleaning
- Wipe the exterior of the transmitter with a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and internal components.
- Regularly inspect the microphone grille for debris and gently clean if necessary.
Battery Care and Replacement
- Replace batteries promptly when the display indicates low power to avoid interruption during use.
- Remove batteries if the transmitter will not be used for an extended period to prevent leakage and damage.
- Dispose of used batteries according to local regulations.
Storage
Store the HT4500 in a cool, dry place, away from direct sunlight and extreme temperatures. Use the original packaging or a protective case to prevent physical damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Dead or incorrectly installed batteries. | Replace batteries with fresh AA alkaline batteries, ensuring correct polarity. |
| No audio output | Transmitter muted; incorrect frequency/channel; receiver not powered or connected; microphone head not properly attached. | Check mute switch; ensure transmitter and receiver are on the same frequency/channel; verify receiver connections; re-attach microphone head securely. |
| Intermittent signal or dropouts | Interference; excessive distance from receiver; low battery; antenna obstruction. | Change frequency/channel; reduce distance to receiver; replace batteries; ensure clear line of sight to receiver antenna. |
| Poor audio quality (noise, distortion) | Interference; gain settings incorrect; damaged microphone head. | Change frequency/channel; adjust gain settings on transmitter and receiver; try a different microphone head if available. |
