This manual provides detailed instructions for the proper use and care of your HeiL GMElite Microphone. The GMElite is specifically designed for amateur radio communications, featuring dual high-performance dynamic elements to accommodate various communication requirements. Please read this manual thoroughly before operating the microphone to ensure optimal performance and longevity.

2. Key Features

• Dual Dynamic Elements: Equipped with two distinct high-performance dynamic elements, selectable via a switch, to suit different communication needs.
• WIDE Position (Heil Elite Element): Provides a smooth, articulate audio response from 60Hz to 16 kHz, with a traditional +4 dB peak centered at 2 kHz. This setting is ideal for a balanced, studio-quality SSB signal with excellent voice articulation and a robust low end.
• NARROW Position (HC-5.1 Element): Delivers a smooth response from 200Hz to 8 kHz. The HC-5.1 element is designed for compatibility with older radio transceivers or for modern transceivers utilizing onboard DSP EQ, offering full-range broadcast audio or tailored DX/Contest audio through EQ adjustments.
• Soft-Touch PTT Switch: Features a Push-To-Talk switch wired to pins 3 and 4 for transmit control.
• XLR Connectivity: Microphone audio is fed to pins 1 (shield) and 2 of the four-pin XLR connector.
• Included Accessories: Comes with a foam windscreen and a 5/8"-27 microphone clip, compatible with standard booms and desk stands.

3.4 Connecting to a Transceiver

The GMElite microphone uses a four-pin XLR connector. It requires a HEIL CC1 Connecting Cable (sold separately) to interface with your specific amateur radio transceiver.

• Connect the XLR end of the HEIL CC1 cable to the microphone's XLR port.
• Connect the other end of the HEIL CC1 cable to the microphone input of your amateur radio transceiver.
• Ensure a secure connection at both ends.
• Note: The PTT switch is wired to pins 3 and 4. Microphone audio is fed to pins 1 (shield) and 2. Consult your transceiver's manual for specific microphone input wiring requirements.

4. Operating Instructions

4.1 Element Selection

The GMElite microphone features a switch to select between two distinct dynamic elements: WIDE and NARROW.

• WIDE Position: Select this for a full-range audio response (60Hz – 16 kHz) with enhanced voice articulation and a strong low end. This is suitable for general SSB communications where a rich, broadcast-quality sound is desired.
• NARROW Position: Select this for a tailored audio response (200Hz – 8 kHz). This element is optimized for older transceivers or for situations requiring a more focused audio profile, such as DX or contest operations, especially when combined with your transceiver's DSP EQ.

4.2 Push-To-Talk (PTT) Function

The soft-touch PTT switch on the microphone controls your transceiver's transmit function.

• Press and hold the PTT switch to transmit.
• Release the PTT switch to return to receive mode.

4.3 Audio Level Adjustment

Adjust the microphone gain and audio processing settings on your amateur radio transceiver to achieve optimal audio levels and clarity. Refer to your transceiver's instruction manual for specific adjustments.

5. Maintenance

5.1 Cleaning

• Wipe the microphone body with a soft, dry cloth.
• Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the finish or internal components.
• The foam windscreen can be gently removed and cleaned with mild soap and water, then allowed to air dry completely before reattaching.
