The CG-1800 from Tascam is specifically designed for small to large-scale video/audio synchronization systems. An OCXO (oven-controlled crystal oscillator) is used for its high precision and because it's not affected by the temperature of the environment. With a clock frequency precision of 0.01 ppm the unit delivers high-precision synchronization with a frequency stability of +/-0.005 ppm or less per day.

External clock jitter is reduced using an original circuit design that incorporates a high-performance video clock generator engineered with a FPGA and a PLL (phase-locked loop) circuit with a discrete filter. This enables a stable clock signal to be provided to the video/word outputs, improving system stability.

In addition to twelve Wordclock outputs and four video outputs, the digital outputs include two AES3/AES11 and two S/PDIF outputs, making this unit useful for large-scale audio/video synchronization systems and a wide variety of other applications. Of the twelve Wordclock outputs, two also support x2 Fs, x4 Fs and 256 Fs output, enabling them to be used in systems with Pro Tools and other DAW software.

The unit features multiple functions to support maintenance and the identification of issues if problems occur, allowing the device to provide troubleshooting support. Additionally, a logging function enables issues to be listed, and saved to a CSV file format on a USB flash drive. A self-correction function allows users to conduct maintenance using an external signal input and simple operations.

Amphenol BNC connectors on the chassis use nuts for coupling for extra durability, along with a single circuit board used for each connector. This provides good resistance to the twisting and pulling of cables, and the suppression of interference between connectors.

  • Internal clock uses a high-precision OCXO (oven-controlled crystal oscillator) that is not influenced by the temperature of the environment
  • External input connector that supports 10 MHz, allowing creation of systems with even higher precision
  • Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
  • Numerous output connectors, including twelve Wordclock outputs, enabling the use in large-scale audio synchronization systems
  • Supports input and output of a variety of video signal formats, including NTSC, PAL and HD Tri-level
  • AES3 and AES11 signals can also be used for external master clock input sources
  • Analyzer function that can measure output device termination
  • Optimal levels can be provided to other devices by adjusting Wordclock output levels
  • Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS) (requires a separate PPS-output 10 MHz oscillator with a built-in GPS antenna)
  • Wordclock performance up to 192 kHz
  • 0.1% pull-up/down for 24F (Film) and 29.97F (NTSC), and 4% pull-up/down for 24F (Film) and 25F (PAL)
  • Up to four system settings can be saved to buttons for recall, and saved settings can be imported and exported via USB
  • Durable Amphenol manufactured nut-coupling BNC connectors
  • Independent circuit boards for each connector prevents contact failures due to twisting
  • Panel-lock switch can be used to prevent inadvertent changes to unit operation
  • 128 x 64-pixel organic EL display with a wide viewing angle
  • Firmware updates possible using the USB port

Great buy!
We utilized this text during my Group Psychology course in my masters program. I felt it was very informative and is referred to highly by several of my colleagues. I had sold the text back to my campus book store a few years ago, but have decided I will benefit from having a copy available to me over my development as a professional. The information within this text, specifically the theories described by Yalom, are also incorporated into the state licensure exam, so it is a good reference to have when studying for this exam as well.

Excellent definitive group process textbook - not dry or verbose
Yalom certainly conveys his knowledge, research, and experience clearly in an organized, interesting, and engaging way that makes this textbook easy reading, but not at all simplistic. Had to stop and "chew" on material often to absorb. A must for anyone who has the responsibility of facilitating a therapy group. Not for support group-related work, especially. This is process group 100%.

The Most Clear and Accessible (Not to Mention Funny) Treatment of the Trinity I Have Ever Encountered
Format: Paperback
The Trinity may be the most difficult Doctrine of the Church to understand and it is even more difficult to explain clearly; yet it is also central and essential to the Christian Faith. This makes it very difficult for those of us in ministry who want to teach about the Nature of God with accuracy, clarity, and care. More often than not, discussions of God’s Triune nature involve analogies of water, apples, hats, and other such symbols that never seem to really help anyone’s understanding and serve only to muddy the theological waters. Stephen Bullivant’s concise, fair-minded, humorous, and incredibly accessible work is truly a breath of fresh air. It has brought much needed relief from bad analogies and incredible clarity to a difficult topic. I will even go so far as to say it has re-shaped both my thinking about and teaching of the Trinity. What I love most about this book is that I can recommend it to anyone. The clarity of thought with which Bullivant writes, and the ease with which he uses pop-culture and humor to illuminate complex ideas make this a rare book on theology that provides the reader with both the erudition of a scholar and the art a communicator. I have been teaching from this book at our church since I read it last Spring and I can attest from the feedback that I have gotten that it has been a game-changer on the topic of the Trinity for many people here. Quite a few have told me that the way Bullivant explains the Trinity has brought them clarity one this the Doctrine for the first time in their Christian experience. I cannot recommend this book highly enough for anyone in ministry that is looking for a way to communicate a very difficult theological topic with clarity, humor, humility, and care.

A Clear, Readable, and Necessary Contribution
Format: Paperback
This is a clear, readable, and necessary book. The Trinity is the central mystery of the Christian faith, but it can be difficult to articulate in a simple and coherent way. As one who regularly teaches the topic in the Catholic high school setting, I appreciated the very accessible approach that the author takes. Anyone who struggles with the basic meaning of the doctrine would benefit from this text, as would those who are tasked with explaining it to others. From the very first page of the book, the author presents the doctrine of the Trinity through three basic statements: 1. There is only one God. 2. The Father, the Son, and the Holy Spirit is each God. 3. The Father, the Son, and the Holy Spirit are not the same. Besides a very good opening chapter on the ability to speak about God at all, the entire book is basically an unpacking of why the Church came to believe in these three statements and the problems (aka heresies) that arise when any one of the three is denied. Over the course of the book, the reader will become familiar with many of the key biblical texts underlying the doctrine of the Trinity and the early theologians who defended it. While this is not primarily a work of doctrinal history, the arguments are almost entirely based on the thought of these fourth and fifth century theologians. Two points are worth noting, though neither was a "deal breaker" for me: First, be ready for lots of references to popular culture. I was surprised to see mentions of everything from Wayne's World and Borat to the song Achy Breaky Heart and the Three Amigos. These are no doubt great examples from the author's experience, as university teacher, in connecting the subject matter to his student audience. But in almost every instance I found myself drawn away from the topic at hand and in some cases I was left pondering the usefulness of the gratuitous reference itself. Luckily, I got almost every single one--until a late reference to the British TV series Father Ted forced me to look it up on Google. Second, I'm not sure if this book is still in such an early printing that it hasn't been physically typeset yet, but my edition looked as though an inkjet printer produced it. In an age of Retina display screens, it was a bit odd being disappointed in the quality of actual printed text. Overall, I highly recommend the book. I've just ordered the author's previous book from Paulist Press and look forward to his future works.

This book is good if you wish to know the heresies of the Trinity. It does not cover the inner working relationships of the Trinity.
