The Kramer VM-1021N is a high-performance distribution amplifier engineered for both composite video and SD-SDI signals. Designed to meet the demands of professional AV, broadcast, and digital signage deployments, this unit ensures reliable signal distribution with smart, controllable compensation for the inevitable losses that occur in long cable runs. With its robust bandwidth, adjustable gain and peaking equalization, and convenient looping input, the VM-1021N delivers consistent picture quality across multiple outputs, making it an essential component in any professional video backbone. Whether you’re upgrading an existing installation or building a new system from the ground up, this compact amplifier provides the flexibility and reliability needed to keep every display synchronized, bright, and sharp.

  • Versatile signal support: The VM-1021N accepts both composite video and SD-SDI signals, enabling seamless integration with legacy equipment and modern digital gear in a single, compact unit. This flexibility reduces the need for multiple adapters and simplifies your signal chain, saving time on setup and testing while maintaining pristine video quality.
  • High bandwidth for peak performance: With a bandwidth specification of 350 MHz (-3 dB), the amplifier preserves high-frequency content and sharpness, minimizing edge artifacts and color smearing across long cable runs. This bandwidth headroom helps ensure that even demanding sources with fine detail stay crisp at the display end, providing reliable performance in busy AV environments.
  • Gain and EQ controls for precise compensation: The VM-1021N provides grouped level (gain) and equalization (peaking) controls, allowing operators to compensate for attenuation and distortion introduced by long cables. By adjusting these parameters, you can balance output levels across channels and recover lost high-frequency content to deliver consistent brightness and contrast across multiple displays, even when cables vary in length.
  • Looping input simplifies daisy-chaining: The looping input lets you feed the signal onward to additional devices without re-terminating or re-cabling. This feature is ideal for AV installations where multiple screens or devices must receive the same source, reducing clutter and preserving signal integrity through a simple, reliable loop-through path that scales with your system.
  • Selectable input signal and rugged build: The VM-1021N includes a selectable input signal option, enabling you to choose between composite video and SD-SDI based on your source. Built for professional use, the unit features robust connectors and a compact, rack-friendly footprint that fits easily into standard AV racks and cabinets, keeping installations tidy, accessible, and easy to service.

How to install Kramer VM-1021N

  • Plan your signal path: Determine which devices will receive the composite and SD-SDI outputs, and identify the longest cable runs where attenuation will be most noticeable. This planning helps you set the gain and EQ so every path remains consistent from source to display.
  • Connect the input: Attach your chosen source to the VM-1021N’s input connector, selecting the appropriate input signal type (composite or SD-SDI) using the unit’s controls or switch, as specified in the user manual.
  • Wire the outputs: Run individual cables from the VM-1021N’s outputs to each destination display or device. If you need to feed additional gear, use the looping input to daisy-chain without disturbing the main distribution path, keeping wiring clean and organized.
  • Adjust the controls: Use the grouped gain control to set the overall output level for each path and the peaking EQ control to compensate for high-frequency loss along the cable. Make small adjustments, then test each route for brightness, sharpness, and color accuracy across devices.
  • Power and verify: Connect the external power supply, power up the unit, and verify that all outputs carry clean video with synchronized timing. If you observe minor artifacts or drift, fine-tune the gain and EQ settings or adjust routing to minimize interference.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book. Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray. I wish it had been proofread - there are a lot of typos, but nothing too distracting.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more. I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things. It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic. I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together. I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray. Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat
