Surface Pro 9 and MS Audio Dock at the Microsoft Visitor Center

Yesterday, I had the pleasure of attending a demo showcase at the Microsoft Visitor Center in Redmond, Washington. The drive was lovely with uncharacteristically warm and sunny weather. It was so warm, in fact, that we were running the air conditioner – in October! There was a bit of haze in the air from all the wildfires on the West coast, but since the air quality index was not in the red, we decided to turn off the air conditioner and cruise with the windows down.

But we didn’t come to enjoy the weather – this trip had a very specific focus:

  1. take measurements of the Surface Pro 9 to see what accessory cross-compatibility there is with the Surface Pro 8 and Surface Pro X

  2. be on the lookout for any cool features that the tech press missed

I can confirm that the Surface Pro 9 is the same form-factor and thickness as the Pro 8, but with the port spacings of the Pro X. Here is a side-by-side:

More specifically, the physical changes between the Pro 8 -> Pro 9 are:

  • volume and power button location changed from sides to top edge

  • no 3.5mm headphone jack

  • USB-C/Thunderbolt ports moved to left-side of device in same spot as the Pro X

  • SurfaceConnect/SurfLink docking port shifted up by 69.8mm to the same spot as the Pro X

Pen and type-cover compatibility is unchanged since magnet and keyboard connector locations are the same. Below are photos showing the measurements of the Pro 9. I used the wrong lens for close-ups so apologies for the mild distortion. Click for higher-resolution photos.

I also got to experience the Microsoft Audio Dock ($249.99 USD). It is a USB-C dock with the following features:

  • Docking

    • integrated 1m USB-C laptop cable

    • 60W PD laptop charging

    • 1x HDMI 2.0 (4K60)

    • 2x USB-C (10Gb/s / 7.5W)

      • one port with DP alt mode for 1x4K60 video or 2x 4K60 via separate MST hub w/DSC

    • 1x USB 3.x (10Gb/s / 7.5W)

  • Audio

    • integrated stereo speakers

      • 2x ~50mm woofers (15W total)

      • 2x ~25mm tweeters (5W total)

    • up to 90dB SPL (probably measured at 1kHz and 0.5m distance?)

    • based on Rockchip RK2108 SoC with integrated audio codec

    • Texas Instruments TAS5805 23-watt Class-D amplifier chip

    • 70Hz-10KHz for music / 200Hz-8kHz for audio/video conferencing

    • two omnidirectional microphone “arrays”

  • Other

    • dedicated Teams button along with volume, mute and pause/play

    • Barrel-jack style PSU

    • optional Presenter+ remote ($79.99 USD)

The build quality is a amazing and the sound even better. The demo staff graciously accepted my request to disconnect the dock from the demo system and we discovered together that the rubber foot has a cavity where you can coil-up the cable. Is this simply to hide the cable to reduce desk clutter? Or is it for travel? Given the size and weight and the companion power brick, I’m not sure how useful this would be for traveling. But then it dawned on me that there could be a forthcoming lithium-ion powered version that could double as a portable wireless Bluetooth speaker.

The MS staff could neither confirm nor deny this.

It is obvious that the Dock was designed with accessibility in mind. Each of the ports has distinguishing tactile bump dots. The full size USB port with two, USB-C one, and HDMI a pill-shaped bar. The USB-C port adjacent to the HDMI port also had a printed logo indicating its monitor capability.

I’m planning a return visit within the next week, so let me know if there is anything you want to know.
