FAQs:
What devices does the SmallRig S70-C2 connect to?
The S70-C2 is designed for content creators and streamers using Android phones. Its USB-C plug-in receiver connects directly to compatible mobile devices and runs on plug-in power from the device. The receiver also includes a port for charging the connected phone while recording. This keeps the setup small, with no separate camera receiver or audio cable needed for phone-based recording.
How discreet are the transmitters on camera?
Each transmitter uses a semi-concealed design with exposed parts measuring 2.9 x 0.9cm. The transmitter weighs just 8.8g, so it sits lightly on a collar without pulling the fabric down. The clip holds it in place while keeping the visible part small. This makes it easier to record clean speech without a large mic drawing attention on camera.
How does the S70-C2 handle loud voices or sudden peaks?
The ATS3031 chip supports 48 kHz/24-bit recording and includes an auto limiter. When a voice suddenly gets louder, the limiter suppresses the peak before it clips and distorts. You can also set the gain level before recording, so the input sits at a more suitable level for the speaker. This gives you more usable audio when recording interviews, vlogs or short videos with changing speech volume.
What sound controls are built into the system?
The S70-C2 includes three noise-reduction levels, five gain levels, and three mixing modes. Noise reduction reduces background sound around the speaker, while gain adjustment raises or lowers the input volume. Mono, stereo, and safety track modes allow different ways to record two speakers or protect against loud moments. Nine EQ presets, including general, rich, bright, male and female, shape the tone for different voices and recording situations.
How long does the microphone system battery last?
Each transmitter runs for up to 8 hours on a single charge. The included charging case has an integrated battery, extending the total runtime to over 40 hours. Between recordings, the transmitters return to the case and recharge while stored. That gives enough power for several days of vlogging, streaming or interview work before the case itself needs charging through USB-C.
