FAQs
What devices can the SmallRig S70-A connect to?
The system includes three receiver types: a USB-C plug-in, a Lightning plug-in, and a camera-mount receiver with a 3.5mm output. This allows it to work with smartphones, tablets, and cameras without needing additional adapters. The plug-in receivers draw power directly from the device, keeping setup simple. You can also charge your phone while recording using the pass-through port.
How reliable is the wireless connection?
The S70-A uses 2.4GHz digital transmission with a working range of up to 300 metres in open conditions. In practice, this gives solid coverage for interviews, walk-and-talk shooting, and wider framing setups. The signal remains stable across typical shooting environments, provided there are no heavy obstructions. It is well-suited to both indoor and outdoor use.
How is the audio quality controlled?
The system records at 48kHz 24-bit and uses an integrated audio chip with auto-limiting to prevent distortion. You can adjust the sound using three noise-reduction levels and five gain levels when connected to a camera. There are also nine EQ presets that tailor the sound depending on the subject, such as speech or music. These controls help keep recordings consistent across different environments.
Can it record two people at the same time?
Yes. The system includes two transmitters, each with a built-in omnidirectional microphone. This allows you to record two speakers simultaneously, such as in interviews or presentations. You can choose between mono, stereo, or safety track modes depending on how you want the audio recorded. The safety track option is useful for protecting against sudden volume spikes.
How long does the battery last during use?
Each transmitter runs for up to 8 hours on a full charge. The included charging case extends the total runtime to over 40 hours, allowing you to recharge between takes or throughout the day. This makes the system practical for longer shoots or travel where access to power may be limited.
