- AKG D660 S Hypercardioid Dynamic Microphone
Note: Additional accessories such as XLR cables or microphone stands are typically sold separately.
Setup
- Connecting the Microphone: The D660 S uses an XLR connector for audio output. Connect a standard XLR cable (not included) from the microphone's XLR output to an XLR input on your mixer, audio interface, or karaoke machine. Ensure the connection is secure.
- Power Source: This is a dynamic microphone and does not require phantom power. It operates via a corded electric connection through the XLR cable to your audio device.
- Placement: For optimal sound capture, position the microphone appropriately for the sound source. The hypercardioid polar pattern is designed to focus on sound directly in front of the microphone while rejecting sounds from the sides and rear.
Operating Instructions
- Powering On/Off: The microphone features an integrated ON/OFF switch on its body. Slide the switch to the "ON" position to activate the microphone. Slide it to the "OFF" position when not in use to prevent unwanted noise or feedback.
- Gain Staging: Adjust the input gain on your connected mixer or audio interface to an appropriate level. Avoid setting the gain too high, which can lead to distortion, or too low, which can result in a weak signal.
- Recommended Uses: The D660 S is versatile and recommended for singing, karaoke, and voice recording. Its hypercardioid pattern makes it suitable for live performances where isolation from other sound sources is desired.
Maintenance
- Cleaning: Use a soft, dry cloth to wipe the microphone body. For the grille, a soft brush can be used to gently remove dust or debris. Do not use liquid cleaners directly on the microphone.
- Storage: When not in use, store the microphone in a dry, cool place, away from direct sunlight and extreme temperatures. Using a microphone pouch or case can protect it from dust and physical damage.
- Handling: Handle the microphone with care. Avoid dropping it or subjecting it to strong impacts, as this can damage the internal components.
Troubleshooting
If you encounter issues with your AKG D660 S microphone, please refer to the following common troubleshooting steps:
- No Sound Output:
- Ensure the microphone's ON/OFF switch is in the "ON" position.
- Check that the XLR cable is securely connected at both the microphone and the audio input device.
- Verify that the input gain on your mixer or audio interface is turned up.
- Test with a different XLR cable if possible, to rule out a faulty cable.
- Confirm that the audio input channel on your device is selected and not muted.
- Distorted or Weak Sound:
- Adjust the input gain on your audio device. If the sound is distorted, the gain might be too high. If it's weak, it might be too low.
- Ensure you are speaking or singing directly into the front of the microphone, utilizing its hypercardioid pattern effectively.
- Check for any damage to the microphone grille or body.
- Feedback (High-pitched squealing):
- Reduce the overall volume or the gain on the microphone channel.
- Reposition the microphone further away from loudspeakers or monitors.
- Ensure the microphone is not pointing directly at a speaker.
If these steps do not resolve the issue, please contact AKG customer support or your retailer for further assistance.
