833 FAQ

Why did you name it the 833?

The 833 is similar to the tried and true 633 but with substantially more powerful hardware.

When can I get one?

The 833 is shipping Monday, 9/16/19.

I own a 633, why should I consider the 833?

The 833 has several advantages to the 633, including:

  • 3 additional microphone preamplifiers
  • 2 additional channels
  • 256 GB Internal SSD
  • 3 recordable media
  • 12 Record tracks
  • Dedicated trim and fader controls for channels 1-6
  • Flexible routing 
  • Recordable Return
  • Dual L-Mount battery charging
  • 3-band EQ on every channel
  • Word Clock In and Out
  • Powerful processing architecture with multiple FPGAs
  • Supports multiple third-party USB control surfaces
  • Advanced transport controls via companion app SD-Remote
  • Post-roll
  • Track arming during recording
  • Track to media routing
  • TA5 headset port
  • Bus Sends
  • Tunable Timecode
  • High speed USB file transfer

How big is the 833?

The 833 is roughly the size of the 633. The 833 has more depth but is slimmer than the 633.

What production bags fit the 833? 

Bags designed for the 633 may or may not be suitable for the 833. This depends on the size of L-Mount batteries attached. For example, the CS-633 bag will house the 833 but only with 2200 mAH L-Mount batteries. 

What are my options for powering 833? 

833 can be powered via DC input on a TA4 connector or two L-Mount batteries. The power sources operate in series, allowing for long run times.

Can the 833 charge the L-Mount batteries? 

Yes. There are two built-in chargers, one for each battery. These can be turned off via the menu.

Why did you choose to use the TA4 for power instead of the 4-pin Hirose on previous Sound Devices products?

Battery charging can draw over 3 A alone, and 4-pin Hirose connectors are only rated for 2 A. The TA4 connector provides up to 5 A per pin and allows for the use of smart batteries.

How should I wire the TA4 to connect to a standard battery?

For a normal battery, only use pins 1 and 4 for connection.

Are the new smart batteries specific for the 833 only?

No, you can use smart batteries from AudioRoot, Inspired Energy, etc. We have our own labeled smart battery called the XL-SmartBattery

What battery information can the 833 read/display?

Various battery telemetry, including accurate time remaining, will be coming in a future firmware update.

Is the 833 difficult to operate?

No – the 833’s tactile interface makes it perfect for run-and-gun productions. However, we recommend taking a couple of hours to familiarize yourself with the 833 before using it in mission-critical applications. For users familiar with Sound Devices’ 633, 664, 688 or Scorpio, the 833 will feel very similar. The menus and physical controls are very much alike. 

How is routing different from the 633 and 788T?

Unlike the 633 and 788T, the 833 has a full I/O matrix and multiple mix buses, just like the Scorpio. Each physical input can be routed to any combination of buses, tracks, and outputs. The 833 features 6 analog inputs, 8 channels, and 12 record tracks.

See Block Diagram

Can I send channels at different levels to multiple buses?

Yes. All channels feed the Left and Right mix bus post-fader. The four additional buses can be fed from any channel, pre- or post-fade, or with a unique bus send level. 

8 channels?

Yes. All 8 channels can be fed from any of the six analog mic or line inputs, AES3 or AES42 (XLR inputs 1), or the Return (Rtn). All channels are fully featured with trim, delay, polarity, high-pass filters, 3-band EQ, stereo or MS linking, and pre- and post-fade limiting. 

See Block Diagram

I see front panel controls for 6 channels. How do I control channels 7-8?

Each of the 8 channels has an associated Channel screen from which you can setup any channel parameter. Trims, faders, and bus sends for channels 7-8 are controlled through their channel screens which may be accessed via the Menu or by using the star toggle switches + PFL toggle. For physical fader and trim control of channels 7-8, a supported third-party USB control surface can be used. 

6 microphone preamplifiers? Do they all support 48 V phantom power?

Yes, and phantom provides a full 10 mA per channel. 

How do I properly wire the TA5 Headset?

When wiring a headset with the TA5 connector, it is important that the balance microphone signals are wired to shielded twisted pair separate from the headphone signals. Keep in mind that there can be >80 dB of amplification between the mic and the headset, and just a bit of bleed between the mic signal and headphone signal can lead to oscillation. 

You can also buy a premade headset, such as these options from Remote Audio.

Does 833 support the SL-6?

The 833 does not support the SL-6. The SL-6 can be used with the Scorpio or 688. 

Can I use my CL-1, CL-2, CL-6, CL-8, CL-9, or CL-12 with the 833?

The 833 is built with an entirely new architecture which does not support these products.

Can I control 833 from a USB Control Surface with linear faders?

Yes. The 833 supports the ubiquitous MCU (Mackie Control Universal) protocol which many USB-connected control surfaces use. You can custom-map buttons on a MCU-based controller to functions on the 833, or use one of the following supported USB control surfaces:

  • iCON Platform M+ (w D2 Display)
  • iCON Platform X+
  • iCON Platform B+
  • Behringer X-TOUCH
  • Mackie MCU Pro

Can I use other MCU controllers not on your list?

Due to the idiosyncrasies present in many controllers, Sound Devices cannot guarantee proper operation with controllers other than the supported controllers listed above. You are able to custom-map 833 functions to any MCU-based USB controller, but we cannot offer technical support in these cases.

How do you get 12 tracks from 8 channels?

Each channel has an isolated track, and adding the four recordable mix buses (L, R, B1, B2) results in up to 12 available recorded tracks.

How many tracks can I record at the various sampling rates?

All 12 tracks can be recorded at 192 kHz.

Can I arm or disarm tracks during recording?

Yes. When a track is armed or disarmed during recording, a new file is created, including the added track, or excluding the disarmed track, respectively. The two files will be sample-continuous. This feature is great for unscripted productions or any production where recording never stops. 

It appears that most recorders have a maximum file size of 4 GB? What if I want to record long events without the files splitting at 4 GB?

833 supports the exFAT file system and RF64 WAV (64-bit) files. This allows file sizes up to 16 EB (ExaBytes – 260). In other words, you can fill up the entire 256 GB internal SSD with a single, unsplit file.

Is there internal storage? 

Yes. The 833 has an internal 256 GB SSD. 

Can this SSD be replaced by a user?

Any user modifications, including drive replacement, nullify the warranty. We highly recommend having Sound Devices Service replace the drive. Replacement drives will be available as a service part in the future. 

What can I use as a file deliverable to production?

In addition to the internal SSD, the 833 can record to two SD cards, which may be easily delivered to post. 

What is the recommended SD cards to use with the 833?

At this time, the Sound Devices SAM-32SD card is approved.

Why won’t the SD card slide easily into the slot?

SD cards must be inserted label-side down. 

My Read/Write speeds from my computer to the 833 SSD and SD cards is slower than I anticipated?

Make sure the USB-C cable in use is USB3.1 or better. USB2 cables do not have all the needed conductors and will greatly reduce transfer speeds.

Can I record to an external drive or USB storage device? 

The 833 can record to the internal SSD, SD 1, and SD 2 simultaneously. USB Storage devices are not supported.

I noticed when I format the SSD and SD cards I’m not seeing the full capacity advertised.

We over-provision (reserve free space on) the media for optimum performance.

Is there a mobile device remote application? 

Yes. The SD-Remote companion Android application is available. The 833 connects via USB to Android tablets, which provides a robust data connection and device charging through a single cable. The app offers a large display for metering and timecode, scene, take and note editing, track arming, soloing, muting, transport control, sound reports, and more.

What are the minimum Android requirements to run the SD-Remote app?

SD-Remote requires an Android tablet running 6.0 Marshmallow. 

Does the SD-Remote app support Samsung DeX?

SD-Remote does not support DeX. It is recommended to disable DeX when using SD-Remote. 

My 833 won’t connect to SD-Remote on my tablet. Is there a workaround?  

On some tablets, data connection performs better when the USB current is limited to 500 mA instead of 1.5 A. Try setting Menu > Power > USB-A Charge Output to 500 mA.

Does the app connect over Bluetooth?

SD-Remote will eventually be supported over Bluetooth connection. 

Will SD-Remote be available for iOS?
Yes, an iOS version of SD-Remote will be available in the future. 

Can I use Sound Devices Wingman?

Wingman is for 6-Series and MixPre II Series only. 

Does 833 have an on-board Dugan Automixer? 

Yes. It is always a pleasure working with our friend Dan Dugan. The built-in Dugan Automixer allows automixing of channels 1-8. Automixing attenuation of each isolated channel is vividly displayed on the front panel LCD and Ring LEDs. 

Will 833 support MixAssist? 

This feature will be available in a future release. 

I work outdoors, how does the LCD perform in sunlight?

We carefully selected the LCD based on size and performance – both indoors and out. The transflective LCD is clearly visible in direct sunlight. 

What does the antenna connection do? 

In the future, the antenna will be used to connect the 833 via Bluetooth to SD-Remote, the companion application for Android and iOS. 

When can I get one?

833 is shipping now. Contact your preferred Sound Devices reseller to place your order. 

Can I use a USB Keyboard, SD-Remote, and a Control Surface at the same time?

The 833 supports USB hubs via the USB-A connector, allowing you to run multiple supported USB devices simultaneously. Run SD-Remote, a USB Keyboard, a supported USB control surface, USB lights, etc…we have not tested USB pencil sharpeners, USB vacuum cleaners, USB lava lamps, or any other such devices.

Will the 833 have Dante? 

The 833 was designed to be a lightweight, portable bag companion. Dante is particularly useful for larger scale cart-based productions with considerably more I/O. If Dante is needed in your workflow, please consider the Scorpio. 

I see 32-bit A/D Converters listed in the specs. Is that the same thing as a 32-bit float bit depth?

The A/D converters used on the Scorpio and 833 are 32-bit resolution parts, but this is unrelated to 32-bit float files. The ability to record in 32-bit float is a future possibility.
