With the Telex BP4000A4M Single-Channel Portable Beltpack Headset Station, you can stay in communication on an RTS, Audiocom, or Clear-Com intercom system. This wired beltpack station features auto-wiring scheme detection, which automatically recognizes the system you plug it into, and configures itself to be used with it.

The beltpack also features intelligent power management, so you can daisy-chain up to 40 beltpacks by using a single (optional) PS-20 power supply. A current pump circuit constantly keeps tabs on overall cable length, versus the actual current consumption, so each beltpack receives the voltage it needs.

The BP-4000 has additional features to help make it easy to integrate it into an intercom system, including guided setup and various communication controls. Connections are made by means of a male, 4-pin XLR connection.

Enhanced Talk Button Control

You have the option to set your talk settings to either "always on", "always off", or "switching". A built-in blinking lamp gives you a visual indicator to incoming calls.

Remote Microphone Kill Switch

Any user on the intercom can instantly mute the mics on all attached BP4000A4M beltpacks by sending an inaudible "kill signal". This feature can be overridden if needed, but is useful to have in situations where an open mic somewhere in the partyline needs to be immediately silenced.

Voice Guided Setup

Rather than configure internal jumpers and switches, short voice prompts help you navigate the menu options to configure the BP4000A4M. If needed, you also have the ability to reset the beltpack to factory default settings.

Headset Compatibility

The BP4000A4M has a 4-pin male XLR port that is compatible with a (separately available) 4-pin female XLR headset. Both dynamic and electret headset microphones are supported.

History of Egypt
Format: Kindle
Egypt has played a vital role throughout history. This book traces and evaluates the history of Egypt from ancient times until the modern period. During ancient times, the Pharaohs created a strong Egypt. During the Ottoman times, Egypt played a significant role as a regional power. Both French and British played a vital role in Egyptian politics. The Suez canal put Egypt, an important player in world commerce. The Nasser regime entered Egypt into cold world politics. The USA managed under Sadat to place Egypt at the American camp. Eventually, Egypt was the first Arab country to sign a peace treaty with Israel after various brutal wars. Egyptian culture dominated western civilization throughout the centuries. The reader will enjoy this book.

Great summary of Egyptian history
Format: Kindle
The book is—as the subtitle states—an “Overview of Egyptian History.” The book is a brief summary of Egypt’s long and interesting history. It starts with historical events: who were the rulers? What territories did Egypt conquer? Who conquered Egypt. The second part of the book discusses social, economic, and religious history. This primer lays out all of the above topics but with little detail so the reader may wish to select topics of interest to study in further depth elsewhere. Because Egypt’s history includes millennia, I find it hard to understand, so reading this book was valuable to me. The book is written in a style that makes it easy to read. It is not at all dry as some textbooks can be. I recommend this book to anyone who wants an overview of Egyptian history and look forward to reading other books in the series.

Far from enthralling, but I did learn
Format: Paperback
This book was a disappointment. It looked like exactly what I was looking for: an overview of the history, society, and culture of Egypt from ancient to modern times that wasn't 500+ pages long. I did learn a fair bit of information, but unfortunately, the book is far from "enthralling." It reads like a high school student's book report. In addition, it sometimes just throws terms out there with no explanation, and I found myself having to consult Google. For example, it says "Since hieroglyphs were difficult to create, the Egyptians developed hieretic writing, which was a type of cursive script. Later, demotic writing was developed for ordinary documents." What is demotic writing? How is it different from hieretic? The book doesn't even provide a picture. I had to go to Wikipedia to find out what these things are. This book needs slightly more detail and an author with better writing style / storytelling abilities. That said, it still may be the best short introduction available.
