Production Sound

If you’ve watched a film or episodic series made in the past twenty years, you’ve heard audio recorded on Sound Devices equipment. Known in particular for mixer-recorders, robust build quality and exceptionally quiet microphone preamplifiers, Sound Devices is the world leader in professional sound equipment for professional sound mixers.

8-Series

Each 8-Series portable mixer-recorder possesses unprecedented recording power, a fully-customizable routing matrix, and a rugged, efficient interface. The Scorpio, 888, and 833 excel in any production scenario thanks to their ultra low-noise preamplifiers, Dante in and out (Scorpio/888), two automixing algorithms, optional noise suppression plugins, remote control from phones and tablets via the SD-Remote application and plenty of flexibility for inputs, outputs, media, control surfaces, and powering.

Longtime Sound Devices user Deian Humphreys, AMPS, purchased a Scorpio for his work on Doctor Who.

“One of the main factors for me in purchasing the Scorpio was its track count. I needed something that would not only accommodate the growing number of tracks that I record on a day to day basis, but also stand the test of time – I doubt I will ever need 32 but it’s reassuring to know that I will never run out of inputs.

The first thing that struck me was how it sounded – I was blown away. Having had a demo of it’s menu and was aware of its capabilities, I hadn’t until now actually listened to the Scorpio. The same microphones, the same headphones, the same ears, the difference was the Scorpio. I was bowled over by what I was hearing and felt completely justified in spending my hard-earned cash!”

Chris Welcker is a production sound mixer based out of New Orleans, Louisiana who primarily mixes feature films and television.

“We would be shooting in everything from swamps, forests, beaches, mountains, plains and on stage. This time, I chose the 833 and SL-2 as the centerpiece for a new system. The 833 could access and control settings of not only the receivers plugged into the SL-2, but also could remotely control the gain on my Wisycom LFA Active antennas….this system provided the perfect balance of size and capability.”

Wireless

Building off the legacy of Audio Limited, Sound Devices wireless combines legendary British audio quality with the best of American design. Designed for the technical demands and requirements of today’s RF-hostile environments, microphones simply sound better on the A20 Digital Wireless System. The A20-Mini transmitter and A20-RX receiver offer forward-thinking features like SpectraBand 470 MHz – 1525MHz Tuning Technology, GainForward Architecture, and full remote control.

Jonathan Wyatt, AMPS, relied solely on the Audio Limited A10 System to capture the finer points of dialogue for BBC and HBO’s hit series “Gentleman Jack.”

“..When the A10’s came out I knew they would sound incredible. Compared with other radios the A10’s sound fantastic! They have a terrific limiter. We love the app, having non-invasive control over the transmitter is great.

I own 14 A10-TX units and there’s no problem with spacing the frequencies. We can get up to 20 kits running in CH38 so that’s fantastic.”

MixPre II Series

The MixPre II Series is lightweight, compact, and highly portable. Its 32-bit float bit depth offers an astounding 142 dB of dynamic range in a small chassis that is perfect for long days of bag work. Like the 8-Series, the MixPre II Series features boutique preamplifiers designed by Sound Devices, so you can get pristine sound during budget productions.

When production sound mixer Matt Brodnick traveled to Japan to work on a film, he packed his MixPre-6 for a lightweight, carry-on-friendly set up.

“With a small cast and simple workflow, the MixPre-6 recorder was perfect for this project…My entire sound kit was built to fit within my carry-on luggage for extra peace of mind.”

Sound Devices Brings Group Powering and Recording to the A20-Mini with Version 2.00

REEDSBURG, WIS., OCTOBER 11, 2021 – Sound Devices is proud to announce that firmware version 2.00 for the A20-Mini and its companion application A20-Remote introduces shared controls for A20-Mini transmitter groups. Now, all transmitters can be powered up and down simultaneously or made to start and stop recording with a single tap from a smartphone or tablet. In A20-Remote, sound professionals can create custom groups with selected transmitters or use an automatically-created all-transmitter group. The high-efficiency Bluetooth® 5.2 connection provides excellent remote control range and near-instant, simultaneous control.

A20-Mini Firmware v2.00

Download Firmware v2.00

Note: To ensure best performance, always run the latest version of A20-Mini firmware with the latest version of A20-Remote. 

New

  • Support for A20-Remote group powering and recording. Allows for control of power on, power off, record, and stop of all transmitters or custom groups.
  • New “LEDs” menu via A20-Remote. Provides options for turning the A20-Mini LEDs on and off. 
  • New “Resume record state upon powering on” option via A20-Remote. When active, the A20-Mini automatically resumes recording if the transmitter was recording when last powered down.

Change

  • Jamming timecode while in record mode now begins a new WAV file stamped with the jammed timecode value.  

Fixed

  • Fixed issue where batteries could drain when A20-Mini was left connected to a timecode source or a powered off PowerStation-8M. 
  • All A20-Mini transmitters inserted in a PowerStation-8M now reliably mount as mass storage devices to a computer. 
  • Fixed issues where timecode could get out of sync.
  • Rare events where A20-Mini goes unresponsive after disconnecting USB-C without first ejecting from the computer no longer occur.

GainForward Samples

These audio samples were recorded to demonstrate the advantage of using GainForward on the A20-Mini versus traditional gain staging found on other analog and digital wireless systems. All files were recorded from the same takes on an 833 via an A10-RX in an SL-2 using a pair of Shure TwinPlex TL46 lavalier microphones.

These are the raw isolated files from the 833 and have not been altered from the original recordings.

Included in the download:

Whisper to Scream A10.wav: The A10-TX gain is set to 40 dB for the take. The first two lines are whispered then the trim gain is reduced to -17 dB on the 833. Notice that even though the trim gain is reduced, the transmitter gain is still too high and yields an unusable distorted file.

Whisper to Scream A20.wav: Using GainForward there is no gain to be set on the A20-Mini. The trim gain on the A20-Mini channel on the 833 is reduced to -2.5 dB. When the shouting starts the audio is unclipped and usable.

Scream to Whisper A10.wav: The A10-TX gain is set to 0 dB for the take. The first two lines are shouted then the trim gain is increased to 47 dB for the whispered portion. Increasing the trim gain drastically brings up the noise floor present on the A10-TX.

Scream to Whisper A20.wav: For the whispered section the trim gain on the A20-Mini channel on the 833 is increased to 44 dB, which yields a usable file with no added noise.
