The red Pro-Fi Series Phonitor x Headphone Amplifier and Preamplifier from SPL offers connections for headphones operated both balanced and unbalanced. It has an advanced built-in dual power amp that drives headphones balanced which is twice the power of the standard 1/4" jack. This tightens the bass response and makes the overall playback even more relaxed and transparent. The front houses a 4-pol XLR connector to connect the balanced headphone. Both the standard and the 4-pol headphone outputs can be used simultaneously.

Phonitor x is not just a headphone amplifier but also a full-fledged stereo preamplifier. There is provision for connecting up to five stereo sources - two in the analog domain offering XLR connectors for a balanced source and RCA connectors for an unbalanced source.

When Phonitor x operates as a preamplifier together with the Performer as power amplifier both units can be wire-linked for simultaneous power on/off. Therefore, both units AMP CTL sockets need to be connected with a 3.5mm mono-jack cable. When switching to headphone, listening the performer can automatically be powered down. To engage this feature set DIP switch #6 on the bottom of the Phonitor x to ON. The Phonitor Matrix delivers the most realistic playback on headphones.

The Phonitor x comes equipped with a DA converter. The available inputs are expanded by USB, coaxial, and optical digital stereo inputs. The DA converter supports sample rates up to 192 kHz with 24-bit. It syncs automatically to the sample rate of the selected digital input.

The VOLTAiR 120V Rail Technology is developed and manufactured to run on an operating voltage of 120V, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers. It reproduces finest details and delivers a totally relaxed sounding audio experience. The music sounds natural and hearing fatigue is reduced.

A fundamental message for preparing the heart, mind and body
Format: Hardcover
"Preparing your heart for marriage: Devotions for Engaged couples" is a great devotional that should be used by certain couples who follow a certain type of Christian spirituality to help prepare for married life. As the author Gary Thomas stresses, marriage is an entirely different ballgame from dating. No matter how long (or how short) you've been dating your beloved, living with them and learning how their personality works in daily marriage life is the key. These are 30 pre-marriage devotionals that do not require a Biblical reading with them, and have questions for reflections at the end. First, the pluses of this book. The black and white pictures and the layout of the book is just gorgeous. This is a perfect gift for a couple who has just been engaged. The preparation for marriage is realistic. This book deals with myths regarding a perfect marriage are, what communication is and how to continue to learn to love the other person even when times are tough (it's called taking your marital vows seriously). Now, the issues I have with the book. There is a big emphasis on being sexually pure before marriage. A lot of people will like this approach. However, some of the most religious people I know don't believe in this anymore, and feel this is a lesser sin. Some people who might be open to Christianity might be turned off by the heavy handiness of this subject in this work. This is a very Southern Baptist approach to sexuality. When I read about the author's credentials (teacher and writer in residence at the Second Baptist Church in Houston, TX which is one of the largest fundamental churches in Tx) I was not surprised by his approach. While I understand this approach and there are scriptural references to this approach, it may not be appealing to those questioning the validity of Christianity or to those who are interested in exploring becoming a Christian. Overall, this is a good gift. My Husband and I are an old married couple by now, and we enjoyed the book together and read it in one sitting, discussing the questions at the end. I think this can be used by older married couples. (We decided to revisit our courting days and asked some of the questions at the end of each devotional in past tense). I note the author seems to have devotionals for married couples and has written 18 other Christian oriented relationship books as of this writing. This is good for engaged or newly married couples who have a fundamental bent, or who are willing to either skip the sexual purity chapters or discuss the importance of sexuality in their present married/engaged life.
