Las Vegas, NV (January 5, 2017)—The annual CES show is underway in Las Vegas, and while the products introduced there tend to be focused on consumer audio, understandably, there’s always some interesting debuts that catch our eye. This year, two items stood out in the annual pre-show deluge of press releases—both are intended for improving audio when using smartphones for video production, so that while the products are inexpensive and aimed perhaps at guerilla video shoots, they also step away from the realm of typical consumer goods.

At $99, Roland is introducing the GO:MIXER, a compact audio mixer for smartphone video production. Compatible with iOS and Android smartphones, GO:MIXER connects digitally via an included cable, providing stereo sound. With multiple inputs available, users can connect a mic, musical instruments, and media players, and mix them all together live while they shoot.

GO:MIXER is powered by the smartphone connection, measures 3.75 inches square and supports connecting up to five sources at once via inputs for a vocal mic, guitar/bass, stereo keyboard, and two stereo line-level devices (such as music players, drum machines, etc.). Front-panel knobs provide hands-on mixing for the mic and instruments. There’s also a stereo output jack for monitoring the sound via headphones or an external amplification system, plus a dedicated panel knob for adjusting the monitor level.

Elsewhere at the show, Samson is unveiling its $199 Go Mic Mobile, which it bills as the world's first professional wireless microphone for smartphones. Users can capture audio on the go via Go Mic Mobile's compact, dual-channel receiver that mounts and connects directly to a smartphone or DSLR camera. The dual-channel receiver allows users to transmit and mix digital audio on two separate channels. The receiver’s rechargeable lithium-ion battery offers up to six hours of high-definition wireless operation without draining a smartphone battery. Mobile filmmakers can also use the included shoe mount adapter to attach the Go Mic Mobile?s dual-channel receiver to a DSLR camera or professional camcorder.

Go Mic Mobile transmits uncompressed, low latency audio and can operate up to 100 feet utilizing the 2.4 GHz frequency band. Go Mic Mobile offers a frequency response of 10 Hz/22 kHz and a bitrate of 48 kHz. It also includes a switchable 1/8-inch headphone/mic output with volume control for monitoring or connecting to an analog input (3.5 mm cable included), and will be available in handheld, lavalier (beltpack) and shotgun mic configurations when it ships in May 2017.
