The 4x1 3G/HD/SD-SDI ASI Switcher from� Link Electronics �is a four-input video switcher that provides a convenient, low-cost way to route high definition and standard definition serial digital signals. This switcher is compatible with 270 Mb/s, 1.5 Gb/s, and 3 Gb/s serial digital interface signals. It can also be used for ASI and SMPTE 310M (19.4 Mb/s) signals, and the reclocking will be automatically be turned off. This switcher automatically equalizes the incoming SDI signal, compensating for greater than 1,000� of cable at 270 Mb/s, greater than 250� of cable at 1.485 Gb/s, and greater than 100� of cable at 2.97 Gb/s. The signal is then reclocked, with automatic rate detection for all popular data rates. The LEDs on the front panel indicate the data rate of the output video.

This multi-definition SDI 4x1 video switcher is capable of equalizing and reclocking all common serial digital signals, since it supports both standard and high definition signals. This makes it suitable for any application. The switcher�s versatility is illustrated by its ability to switch from SD to HD, SD to 3G, HD to 3G, and vice-versa. Another feature of this switcher is its ability to vertical interval switch when the inputs are synchronous. Vertical interval switching means that the switching takes place in the vertical interval of the video and therefore no glitch is seen in the active area of the video.

The 4x1 3G/HD/SD-SDI Switcher is a 1 RU chassis that is housed in the same case as the well-accepted 700 series. A black front panel distinguishes between the two series. Three 500 or 700 series can be mounted in the PRT-700 rack tray (sold separately).

One of the best Bat stories that I've read.
Format: Paperback
Coming off from The Long Halloween, Jeff Loeb and Tim Sale give us the sequel to their popular story tale in which we see Batman go at it with another year long mystery, while also giving us an origin story for the first Robin, Dick Grayson. After reading this book, I have come away having with even more love of the Dark Knight's mythology, while coming to see this as my favorite Batman story that I have read, even if it doesn't stand as well on its own. ON the narrative side of things, Loeb delivers a story fairly similar to the one he gave in The Long Halloween, though I feel this one is a bit more polished than Halloween was. Some have said that the retreading of plot structure have limited the way Loeb's later works are read, but I myself have no problem with it (for the most part), Loeb manages to do enough differently that you don't feel like you're reading the exact same story. The real big negative I'd have to give this graphic novel is that it really doesn't stand as well by itself than if you had read The Long Halloween. While I myself read that story before coming in to this one, I did see many connections that I would assume would through off any newcomers who hadn't read the prior story. But I will say that this is the story that had me invested the most emotionally. Without giving away any spoilers, that last page in the novel gave me such a cathartic experience that I really came to appreciate certain aspects of the Dark Knight's mythology, and how themes of loneliness were touched upon in a very genuine way. Looking at the art for the novel, Sale's work has improved much from The Long Halloween. I always mention in reviews concerning Sale that I was originally not a fan of his art, but after going through his work, you can't help but admire the level skill he manages to put in his drawings. There is a very big noir feeling in this novel (a plus for ) that is just delivered so well that any preferences in art I may have against Sale are put away in admiring the way he plays with lighting in the story. My biggest complaint for the art, which is a more of a personal thing really, is that I do not like the "pixie" costume they gave Robin (which is his default costume that many would associate him with). I have never really liked this costume, probably never will, but again, this is just me. Overall, I would say I really enjoyed the novel and would have to recommend it to any fans of the Batman (although I'd make sure you have read The Long Halloween first). This has come to be one of my most favorited Batman stories I've read, and I hope others will receive the same level of satisfaction that I have.

Great Sequel to Long Halloween
Format: Paperback
This takes all of the great elements of the Long Halloween and keeps it going. The two of those books together is a great story telling. Ticks all the boxes of a great Batman book. If you like this and Long Halloween check out The Penguin show on HBO Max. and if you like The Penguin but haven't read these two books you should since the show pulls a lot of influence from them.
