The Whirlwind PB12 is a passive press box microphone output expander, housed in a rugged steel case, for Whirlwind's PRESSPOWER 2 and PRESSMITE active press box line outputs, or any other live press conference or forum application where a line level feed is available. It is intended for broadcast and commercial conferencing applications.

The PB12 distributes one line level input to multiple mic level outputs. Each output is transformer-isolated, providing superior interchannel isolation and ground lifting, helping to noise problems. Whirlwind's own TRSP-2 transformers are used throughout.

For Use in Press Conference Situations    1 x Line Input    12 x Mic Outputs    Transformer-Isolated Outputs    Ground-Lifted Outputs    Rugged, Cold-Rolled Steel Construction

1 to 12 line in/microphone out passive press box expander for broadcast and business conference applications

Rugged, all-steel housing with convenient carrying handle

Transformer isolation and grounding for each output eliminate interchannel and RF noise

Q: 1. When shooting in slower 1080p rates, can the camera downsample from 4k internally and without line skipping?

A: Yes. In HD, you can downsample from 4K internally without line skipping. This is similar to the URSA Mini Pros.

Q: 2. Any plans to add a Super16 crop mode?

A: You can do an HD window crop in camera that would work for S16 lenses. To get full sensor 4K a third party would need to create an expander

Q: 3. Which is better for film,A7III or BMDPCC4K?

A: neither use film, they are DIGITAL

Q: 4. Does the HDMI output contain audio channels for viewing in an external monitor?

A: Yes, the HDMI output contains 2 channels of audio for monitoring.

Q: 5. Will there be a crop mode which accommodates the S16 lenses many of us bought to use on the original Pocket Cinema Camera?

A: You do an HD window crop in camera that would work for S16 lenses. To get full sensor 4K a third party would need to create an expander.

Q: 6. Most of us who dedicate ourselves to video, we have several EF frame lenses. My question is, there are 2 types of EF lens adapters to M4 / 3. One that everyone uses for the GH5 and another that is designed for the BM Pocket. This last adapter of Metabones is totally compatible with the camera for being 4k or even there is not a perfectly compatible adapter for this camera? And my other query is that a 14mm and a 24mm in how much varies the focal length with the adapter?Thank you

A: Since the camera hasn't been released yet, we don't know if those adapters will work with this camera. The Pocket Cinema Camera 4K has a 1.9 crop factor when compared to a full frame sensor which would make a 14mm lens 26mm and a 25mm lens a 46mm.

Q: 7. Will there be a crop function in 4K/UHD to Super 16 size so we can use our C-Mount lenses??

A: Hmmm my answer was deleted I see...

Q: 8. Can we use the BlackMagic SpeedBooster from the original pocket camera?

A: While it will still be mechanically compatible, the BMPCC Speedbooster is for a specific sensor size. Since the sensor in this camera is bigger than the Pocket CinemaCamera, it will not be optically compatible and vignetting will occur.

Q: 9. On the B&H specs sheet for the BMPCC 4K, it says that the data rates for RAW are 21 to 203 MB/s. On the specs sheet provided on the Blackmagic site, it say that the highest possible data rate for RAW is 135 MB/s. Has there been an update and B&H didn't change their specs sheet? Or is this simply a mistake on B&H's specs sheet?

A: The 203 Mb number is listed on the Blackmagic site in the constant quality mode. The two sites have the same numbers but may not be presented exactly the same. The manual has a more complete listing of rates and formats.

Q: 10. What is the maximum/fastest shutter speed?

A: With the camera not being released until the fall, this is not information we have available at this time. Once we get closer to the camera's release and the manual is available online, we should be able to answer this question.
