Saramonic Ultra 04

Two white transmitters with 32-bit float onboard recording and timecode, a receiver with an AMOLED touchscreen, an external antenna and a charging case — plus two lavalier microphones. A two-channel system for camera, phone and computer.

A transmitter with 8 GB of memory

The transmitter weighs 35 g, measures 45.5 × 33.5 × 15 mm and has a fixed metal clip. Its built-in MEMS microphone handles up to 130 dB SPL, and a 32-bit float backup is recorded to 8 GB of memory. The IPX5 rating withstands rain, and an external microphone can be plugged in too.

A receiver with a touchscreen

The 1.1-inch AMOLED touchscreen and a control knob set gain, noise cancellation and output mode. The detachable external antenna extends the range from 250 to 300 m. The receiver offers real-time monitoring, playback without unplugging and output to two devices at once.

A 2,900 mAh charging case

The case holds and charges both transmitters and the receiver. Its 2,900 mAh battery extends the total runtime of the kit to 24 hours. The case measures 117 × 48.5 × 62.4 mm and weighs 210.5 g.

Two lavalier microphones

The kit includes two lavalier microphones with 3.5 mm plugs that connect straight to the transmitters. Use them wherever the microphone should hide under clothing or sit closer to the speaker’s mouth — in interviews, reports and weddings.

Up to 24 hours of runtime

The transmitters and the receiver run 6 hours per charge and can be charged while recording. The 2,900 mAh charging case recharges them more than once, so the whole kit keeps going for up to 24 hours.

32-bit float recording

With onboard recording enabled, the transmitter stores audio at 48 kHz / 32-bit float. Quiet and overloaded passages can be evened out in post without clipping or added noise. Files are split every 30 minutes, and the oldest recording is overwritten when the memory is full.

ClearVoice and auto gain

ClearVoice noise cancellation switches on with a single press and has three levels in the app. Vocal Boost and a 150 Hz Low-Cut shape the voice, and automatic gain control (AGC) keeps levels in check without manual adjustment.

Mono, stereo and safety track

In stereo each transmitter records to its own channel; in mono both are combined into one. The safety track mode records a backup 6 dB lower; to use it, the tracks must be separated in post-production.

Studio-grade sound

Sampling at 48 kHz / 24-bit, a signal-to-noise ratio above 90 dB and a 20 Hz – 20 kHz frequency range capture vocal detail with minimal noise in any environment.

Recording with headroom for post

32-bit float onboard recording captures a wider dynamic range than regular 16-bit or 24-bit recording. Each transmitter has 8 GB of memory and doubles as a standalone recorder; recording can start automatically at power-on so you never forget to press record.

Loud places without clipping

A street concert, singing or motorsport: in low gain mode the transmitter handles up to 130 dB SPL without distortion. ClearVoice noise cancellation and automatic gain keep speech intelligible even in busy surroundings.

Up to 300 metres of range

In addition to two built-in antennas, the system has a detachable external antenna that boosts the signal and extends the range from 250 to 300 m. With 25 ms latency the link also suits sports and action shots from a distance.

Additional information

The Saramonic Ultra 04 wireless microphone system delivers professional sound for demanding content creators. Designed for two people, it includes two compact clip-on transmitters with built-in omnidirectional microphones, two lavalier microphones and 32-bit float recording with timecode for precise audio-video sync. Its advanced features include ClearVoice noise cancellation, automatic gain control and IPX5-rated transmitters for reliable use in any environment.

The two-channel receiver connects via 3.5 mm TRS, USB-C and Lightning, so it works with cameras, phones, tablets, computers and recorders. The external antenna extends line-of-sight range to up to 300 m, and 128-bit encryption protects the transmission. Both transmitters record internally at 32-bit float / 48 kHz to 8 GB of memory, and files transfer over USB-C. The included charging case recharges the kit on the go.

The white finish blends discreetly with light clothing, which makes the kit a good fit for weddings, interviews, podcasts, livestreams and filming on the road. The Saramonic Ultra 04 comes with all the accessories you need to start recording wirelessly straight away.

The receiver measures 54 × 34.1 × 18 mm and weighs 37 g. The transmitters have a 495 mAh battery and the receiver a 465 mAh battery; each runs about 6 hours and recharges in 1.5 hours, while the charging case takes about 2 hours to charge. The 2.4 GHz link uses GFSK modulation, and both transmitters hold up to 10 hours of internal recording at 32-bit float / 48 kHz.
