The Blackmagic Design Spares - Smart Videohub 20x20 - PCB Front is the dedicated interface and control board for the 20x20 model of the Smart Videohub. This component is situated directly behind the front panel and acts as the physical interaction layer between the operator and the main routing engine.

Front Panel Control Logic

This PCB is responsible for translating every manual command into data that the Main PCB can execute. It manages the specialized components that allow for "at-the-router" crosspoint changes:

  • Rotary Encoder Interface: Houses the logic for the machined metal spin knob, allowing for high-speed scrolling through dozens of inputs and outputs.

  • Button Matrix: Controls the tactile buttons for "Take," "Clear," and menu navigation, including their integrated backlighting.

  • LCD Driver Logic: While the LCD itself is often a separate panel, this board contains the bridge circuitry that sends video thumbnails and source/destination labels to the screen.

Visual Feedback and Monitoring

The Front PCB is essential for the Videohub's unique "Visual Routing" feature. It coordinates the display of live video icons on the front panel LCD, ensuring that as you scroll through ports, you get a real-time visual confirmation of the signal. If the front display is flickering, the buttons are unresponsive, or the spin knob is skipping entries, the Front PCB is the likely culprit.

Connectivity and Communication

The Front PCB connects to the Main PCB via a high-density ribbon cable. This connection is the lifeline of the front panel, carrying:

  • Power: Drawing voltage from the main power distribution to run the LCD and button LEDs.

  • Command Data: Sending user-initiated routing changes to the crosspoint matrix.

  • Status Data: Receiving label information and signal status from the Main PCB to display to the user.

Key Features

  • Genuine OEM Part: Specifically engineered for the Smart Videohub 20x20 chassis.

  • Direct Tactile Restoration: The primary fix for mechanical failures of the front buttons or the rotary encoder.

  • Integrated Design: Comes pre-populated with all necessary switches and the mounting bracket for the spin knob.

  • Plug-and-Play Internal Interface: Designed for a straightforward connection to the internal wiring loom.

Technical Installation Note

Replacing the Front PCB is less invasive than a Main PCB swap but requires careful handling of the unit's aesthetics:

  • Faceplate Removal: You must remove the front magnesium alloy faceplate to access the mounting screws for the board.

  • Encoder Alignment: When re-installing, ensure the rotary encoder shaft is perfectly centered in the faceplate opening before tightening to prevent the knob from rubbing or sticking.

  • Ribbon Cable Safety: The cable connecting this board to the Main PCB is sensitive to electromagnetic interference; ensure it is routed along its original path and seated firmly in its ZIF (Zero Insertion Force) connector.

  • LCD Protection: During the swap, be careful not to touch the surface of the LCD or the inside of the acrylic window to avoid trapping fingerprints or dust that will be illuminated by the backlight.

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.

Mid.
Color: Light Purple
The chair is fine, and reasonably easy to put together. However, I've been using it for a little over a year and a half, and it's already falling apart. Random parts of it have fallen off, which is fine because it was still functional. But now the most frustrating part is that the wheels continue to pop off, and while the first attempts to pop them back on worked, they will not stay on now. This is obviously greatly impacting the stability, and I will need to purchase a replacement soon. For this price and lack of long-term durability, I would not buy again.

Alexa messed me up, but the company of the chair made it right!
Color: Light Purple, Color: Light Purple
I wanted something small with arms that moved out of the way when I wanted to slide my chair all the way into my desk for more space. This fit the bill. I loved the color blue and I had that in my cart for a bit. One day Alexa mentioned that an item that was in my cart was on sale. It was the chair. I let it be ordered. When it came it didn't exactly look blue to me. But I kept putting it together thinking maybe it was the lighting in the room I was assembling it in. I brought it to my craft room and lo and behold it is light purple. I looked at my order and sure enough it said light purple. Boo! I looked in my saved cart and the chair was gone. So I accepted it for an error. The next day I checked to see if I could return it. Thought I could, till I read that I would have to pay to return it. So I wrote the seller to tell them to ignore the return. And that was that. Till a couple days later I get an email from the seller asking if I would like a full refund or a replacement at no cost. I was like heck yeah send me the blue one. I was thrilled and I wanted to thank the seller for doing this without the return of the other chair. But I could not find a place to do that now. So here is where I will thank you. Thank you so much for doing this for me. You guys are AWESOME!. I love the chair and I love the blue color. I find it very comfortable, lite, easy to adjust, the size works great for me, and for the price the quality fits my needs. I do hope it lasts me for quite some time. Thanks again!

Awesome chair definitely recommend
Color: Blue, Color: Blue
It was amazing the color was spot on and it was very very easy to put together and the size is amazing for my 11 year old daughter maybe not for an older person it doesn’t recline as much as it says so if you want a reclining chair maybe I don’t recommend this chair but the quality is amazing and the adjustment capability is incredible the noise level is at 0 it is an amazing chair we just got it so I don’t know so much about the dupability so if you want this chair for a child or a tween maybe even a teen easy to put together beautiful blue color this is the chair for you.

Easy instructions, comfortable cushions
Color: Pink
I just put it together and I love it!!! It's so comfortable and it was easy to put together. You can rock it back and forth which helps your back. The seat is very wide and the cushion is thick. Pink is my favorite color, and this chair satisfies my pink obsession.
