The m501 from Grace Designs is a 500 series microphone preamp module, based on the company's m101 microphone preamp. While the 500 series market has plenty of colored preamp options, the natural, musical clarity of the m501 makes it a welcome addition. This circuit is for engineers who wish to capture their sources with as little coloration or distortion as possible.

The m501 module features a balanced, transformerless design, with 48V phantom, a 75Hz high-pass filter, and a 1/4" HI-Z instrument input. Also standard is a ribbon microphone mode, which raises the input impedance, bypasses the input decoupling capacitors and deactivates 48V phantom to protect delicate ribbon microphones from damage.

Definitely Recommend
Format: Paperback
This book is very helpful and I definitely recommend it as a resource. It simplifies complex concepts and is organized by body system. It highlights the major health conditions in each body system and provides a simple and concise explanation. At the end of every concept a mini quiz is offered to test comprehension. I’ve found this book very useful during the semester and I’m sure I’ll find it helpful for boards.

I worked through this book and used the on-line accompaniment prior to testing for my NP license. I passed, so I’d say it was effective!

It's good but Leik is better
Format: Paperback
This is a fairly good review book for the FNP exam and I've had professors recommend it's use. However, the review book by Leik is better in that it delivers information in a short-and-sweet way that still covers the most crucial information. Fitzgerald requires a little more reading and unfortunately I just don't have the attention span for that anymore. I need short paragraphs, bullet points, and the most crucial information that will give me success for the FNP exam and Leik provides that a little more than this.
