3.2. Præstationskarakteristika
- Extended frequency response for natural sound reproduction.
- Meget lav selvstøj for rene optagelser.
- Exceptional low-frequency reproduction.
- High output level and high input SPL capability.
- No cross-over distortion.
- Extremely uniform polar response.
- Superior common mode rejection and suppression of radio frequency interference.
4. Opsætning og tilslutning
The Shure KSM32 is a condenser microphone and requires 48V phantom power to operate. Ensure your mixer, audio interface, or preamplifier provides phantom power before connecting the microphone.
- Montering: Secure the KSM32 microphone into the provided shock mount or swivel mount. Attach the mount to a standard microphone stand.
- Forbindelse: Connect a balanced XLR cable from the microphone's output to an input on your mixer, audio interface, or preamplifier. Ensure the XLR cable is in good condition.
- Fantomkraft: Activate the 48V phantom power on your connected device. The microphone will not function without it.
- Få Staging: Adjust the input gain on your mixer or interface to achieve an appropriate signal level, avoiding clipping or distortion.
5. Betjeningsvejledning
5.1. Betjening og justeringer
The KSM32 features two switches on its body for sound shaping:
- Attenuation Switch (Pad): This switch provides a 0 dB or -15 dB attenuation. Use the -15 dB setting when recording very loud sound sources (e.g., close-miked drums, loud guitar amplifiers) to prevent input overload and distortion in your preamplivligere.
- Lavfrekvent filterkontakt: This switch offers three settings:
- Flad: No low-frequency roll-off.
- -6 dB/octave below 115 Hz: Reduces low-end rumble and proximity effect.
- -18 dB/octave below 80 Hz: Provides a steeper low-frequency cut for more aggressive rumble reduction or to compensate for extreme proximity effect.
5.2. Anbefalede anvendelser
The KSM32 is a versatile microphone suitable for a wide range of recording and live sound applications:
- Stemme: Solo vocals, background vocals, voice-overs, broadcasting.
- Akustiske instrumenter: Piano, acoustic guitar, drums, percussion, strings.
- Wind Instruments: Brass and woodwind instruments.
- Low-Frequency Instruments: Double bass, electric bass, kick drum.
- Overhead Miking: Drums or percussion.
- Ensembles: Choral or orchestral recordings.
- Værelsesstemning: Capturing the natural sound of a room for guitar amplifiers or drums.

7. Vedligeholdelse
Proper care and maintenance will ensure the longevity and optimal performance of your KSM32 microphone.
- Rensning: Use a soft, dry cloth to clean the microphone body. Do not use harsh chemicals or abrasive cleaners. For the grille, a soft brush can be used to gently remove dust or debris.
- Opbevaring: When not in use, store the microphone in its padded carrying bag to protect it from dust, moisture, and physical damage. Avoid storing in extreme temperatures or high humidity.
- Håndtering: Always handle the microphone with care. Avoid dropping it or subjecting it to strong impacts, as this can damage the delicate internal components.
8. Fejlfinding
If you encounter issues with your Shure KSM32 microphone, refer to the following common troubleshooting steps:
- Ingen lydoutput:
- Ensure 48V phantom power is enabled on your mixer or interface.
- Check all cable connections. Try a different XLR cable to rule out a faulty cable.
- Verify that the input gain on your mixer/interface is set appropriately.
- Confirm the correct input channel is selected on your audio device.
- Forvrænget lyd:
- If the sound is distorted, check if the -15 dB attenuation switch is engaged for loud sources.
- Reduce the input gain on your mixer or interface.
- Ensure the microphone is not placed too close to an extremely loud sound source without proper attenuation.
- Excessive Low-End or Rumble:
- Engage the low-frequency filter switch to reduce unwanted low-end noise or proximity effect.
- Adjust microphone placement to reduce proximity effect (moving the microphone slightly further from the source).
- Intermittent Sound or Noise:
- Inspect XLR cables for damage or loose connections.
- Ensure the microphone is securely mounted and the internal shock mount is functioning correctly to minimize handling noise.
- Check for potential sources of electromagnetic interference (EMI) near the microphone or cables.
If these steps do not resolve the issue, please contact Shure customer support for further assistance.
