Saramonic Ultra 03 Black + 2 Lavalier Microphones Saramonic

Podrobný popis

The Saramonic Ultra 03 is a professional two-channel wireless microphone system with timecode for straightforward sound and picture alignment. It offers 32-bit float onboard recording, handles up to 130 dB SPL without clipping and, with its detachable external antenna, keeps the link stable at up to 300 metres. The black kit also includes two lavalier microphones and is built for film production, live events and demanding sound environments.

Saramonic Ultra 03

Two black 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.

Timecode for multi-camera shoots

Built-in timecode stamps every clip with frame accuracy, so audio and video from several cameras line up in post within seconds. Supported frame rates are 23.98, 24, 25, 29.97 DF, 29.97 and 30 fps; for any other rate choose the closest one, for example 23.98 fps for 47.96 fps.

Clean sound even in noise

Loud singing, motor racing or filming next to aircraft: in low gain mode the transmitter captures sound up to 130 dB SPL without clipping and keeps levels above 125 dB in check. ClearVoice noise cancellation filters out the background noise.

Rain is no problem

The transmitters are IPX5-rated, so rain does not have to stop the shoot. Transmitters and receiver run 6 hours, can be charged while recording, and with the charging case the kit keeps going for up to 24 hours.

Additional information

Built-in timecode syncs sound and picture with frame accuracy across several cameras within seconds, which greatly simplifies post-production. Distortion protection helps capture clean sound even in extremely loud surroundings, while the detachable external antenna strengthens the signal and extends the wireless range for reliable production use.

8 GB of internal memory backs up the wireless transmission and stores 32-bit float recordings with the dynamic range needed to rescue both quiet and overloaded passages in post. ClearVoice intelligent noise cancellation is joined by Vocal Boost and Low-Cut modes, and automatic gain control adjusts levels while recording. The transmitter is IPX5-rated against water and heavy rain. A 1.1-inch HD AMOLED touchscreen gives direct control of the receiver, and 3.5 mm TRS, USB-C and Lightning connectivity supports cameras and mobile devices. The transmitters and receiver run up to six hours per charge.
