With an impressive 2 x 95 watts RMS at 2 Ω, the little QUANTUM QS-TWO is anything but slim. On the contrary, it drives loudspeaker systems with 4, 3 or 2 Ω impedance without difficulty and remains very stable even under critical loads. With a mono bridge output of 190 watts RMS at 4 Ω, it can also elicit a lot of bass from subwoofers. Incidentally, it impresses with its high-end sound: thanks to the huge bandwidth of up to 60,000 Hz and a sensationally low distortion factor of <0.007% (THD + N @ 5W), the QS-TWO is way ahead.

ESX masters the construction of Class D power amplifiers so well that the QS-TWO can come up with a sensational efficiency of up to 90% and EMC interference-free. The modern technology saves electricity, relieves the vehicle's electrical system and protects the high-quality components from overheating. Thanks to the high degree of efficiency, no thick power cables need to be pulled. If you want it to be very easy, you can use the QS-TWO-ISO, which can be supplied via a pre-assembled ISO cable harness, e.g. can be connected behind the car radio.

Very basic
Format: Paperback
The idea of the book is to be condensed and concise but there is too much information that should be expanded on that is not. The writers of this book seem to think students using the book have a strong pediatric background but for FNPs that isn’t always the case. I found myself having to do research outside of the book to understand the chapters. Also there were many typos and mislabeled diagrams.

Poorly written
Format: Paperback
I had to get this for my class. I wish I had a different textbook because it is poorly written, does not explain details, hard to follow the sentences in a certain sections, A LOT of typos (totally misspelled name of the disease). I don't think this is very good textbook material.
