FAQs

Can I record directly to my phone?

Yes, the system is designed with USB-C compatibility for direct recording into mobile devices.

How long does the battery last?

The transmitters offer up to 8 hours of use, and the charging case provides enough power to extend that to over 40 hours total.

Does the system support stereo recording?

Yes, the S 70 supports mono, stereo, and safety track recording modes for flexible post-production editing.

Can I adjust the audio while recording?

Yes, you can adjust the 5-level gain and noise reduction settings directly via the controls on the transmitter.

Is the microphone system compatible with DSLRs?

Yes, the system includes a dedicated camera-mounted receiver that attaches to the hot shoe of most mirrorless and DSLR cameras.

Troubleshooting

No audio signal detected on the recording device

Check the connection cable between the receiver and your device; ensure the gain level on the transmitter is not set to mute.

Intermittent audio dropouts

Ensure a direct line of sight between the transmitter and receiver, and verify that the system is not operating near heavy 2.4 GHz interference sources like Wi-Fi routers.

Audio sounds distorted or 'peaking'

Reduce the 5-level gain setting on the transmitter until the signal levels in your recording software show a safe peak range (typically around -6dB).

Pros and Cons

  • Comprehensive dual-channel recording for two subjects
  • Excellent battery life with portable charging case
  • High-fidelity 24-bit audio capture
  • Broad compatibility with cameras and mobile devices
  • On-device EQ and gain controls for quick adjustments

Cons

  • Transmitters may be bulky for certain clothing styles

Setup, Compatibility & Care

To begin using the S 70, simply remove the transmitters and receiver from the charging case. The system typically pairs automatically upon removal.

Compatibility: The system connects via the included camera-mounted receiver or the direct USB-C interface for mobile devices. Always ensure your device firmware is up to date to support external audio input.

Care Instructions:

  1. Keep the charging case closed when not in use to prevent dust accumulation on the charging pins.
  2. Clean the microphone capsules with a soft, dry brush to avoid moisture buildup.
  3. Store in a dry environment to protect the internal lithium-ion batteries.
  4. Avoid over-tightening the camera-mount adapter when attaching it to the hot shoe.
