Radial Engineering HIGHLINE STEREO Stereo Passive Line Guitar Amp IsolatorAmp simulators are more popular than ever, but they present a unique set of problems for guitar and bass players who want to interface them with a PA system. While amp sims can produce line level outputs, they often have " unbalanced connectors that aren't designed for long cable runs, and they encounter hum and buzz from ground loops when connected directly to the PA. The Radial Highline Stereo is the ultimate line isolator for stereo amp simulators

Amp simulators are more popular than ever, but they present a unique set of problems for guitar and bass players who want to interface them with a PA system. While amp sims can produce line-level outputs, they often have ¼" unbalanced connectors that aren't designed for long cable runs, and they encounter hum and buzz from ground loops when connected directly to the PA. 

The Radial Highline Stereo is the ultimate line isolator for stereo amp simulators and pedalboards. Equipped with dual Jensen transformers, the Highline Stereo delivers clean, balanced signals with maximum clarity and retains the full output of your gear. Designed with Radial’s rugged build quality, it’s a dependable choice for live or studio use. Dual XLR and Thru outputs handle stereo setups, while XLR Sum and Thru Sum functions provide seamless mono compatibility without compromising your tone.

Features

  • No loss of signal strength or tone when connecting to a mixer.
  • Radial's renowned reliability and build quality. 
  • Precision-wound Jensen Transformer delivers exceptional clarity and warmth.
  • Passive, plug-and-play design requires no external power. 

Input 

  • Stereo Inputs: Left and right ¼" input jacks to connect to the balanced or unbalanced outputs from amp sims & guitar pedals.
  • Thru: Left and right ¼" outputs to feed a pair of stage amplifiers.
  • XLR Sum: Sums the left and right input channels to mono at both XLR outputs, allowing you to retain your pedalboard settings when there’s only room for a mono input on the mixer.  
  • Thru Sum: Sums the left and right input channels to mono at both Thru outputs, allowing you to feed a stereo signal to the mixer while monitoring locally with a single amplifier

Output

  • Stereo Outputs: Stereo XLR outputs provide balanced & isolated signals for feeding the inputs of a mixer.
  • Lift: Ground lift switch eliminates hum and buzz from ground loops

Just Right!
Format: Hardcover
Now in its second edition, this book by Terry G. Carter, J. Scott Duvall, and J. Daniel Hayes lives up to its subtitle: a hands-on approach to preparing, developing, and delivering the sermon. It strikes me as a success because of its clear value as a first textbook for someone learning how to put together a sermon. It does better than most at keeping a big-picture view as it assembles the pieces of the sermon. There are other books that, perhaps, dive deeper into the details – the works of Jerry Vines comes to mind – but this one may be “just right” for a wide array of readers. The book is divided into three parts: eight chapters on developing and preaching a sermon, three chapters on preaching the New Testament, and four chapters on preaching the Old Testament. Duvall and Hays had earlier produced a hermeneutics textbook entitled Grasping God’s Word, which is also published by Zondervan, so this book assumes an understanding of hermeneutics and goes straight into putting together a sermon after that work has been done. The first chapter introduces their 11-step sermon process. Chapter 2 covers the first five steps: grasp the meaning of the text in their town, measure the width of the interpretive river, cross the principlizing bridge, consult the biblical map, and grasp the text in our town. As you can see, they word this information in practical terms aimed at our maximum understanding. Again, they avoid being either too shallow or too deep and succeed at being “just right”. After all that wonderful help for putting the sermon together, the other two parts on the Old and New Testaments look at the genres and their unique challenges for the preacher found in each. Most of these were wonderful. The value of the chapter on preaching Revelation might correspond to your own prophetic viewpoint. Actually, they tell you that that might be the case when you preach the Book of Revelation. If you’ve been called to preach and are trying to figure out how to put a sermon together, you owe it to yourself to check this book out. I received this book free from the publisher. I was not required to write a positive review. The opinions I have expressed are my own. I am disclosing this in accordance with the Federal Trade Commission’s 16 CFR, Part 255.

Great reference
Format: Paperback
I used this reference a good but when I was new to practice in a walk-in clinic. From animal bites to corneal abrasions to toenail avulsions, it gave concise treatment recommendations that helped me through my cases. While I need to rely on it a lot less now, I did purchase this to update an older edition and I’ve been equally happy with it

Terrific resource
I work in an urgent care and have been practicing for a little over a year now. This is the perfect resource! I love the ebook option as well with videos that walk you through some procedures. I would definitely recommend buying this if you are a new provider or new to an urgent care setting!
