Description

SPL Pro-Fi Series Phonitor x Headphone Amplifier & Preamplifier with DA Converter and VOLTAiR Technology (Silver)The silver 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.

The silver 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.

Not true to size
Size: 8, Color: (100) White/Pomegranate/Rush Red
The shoes are beautiful, same as the picture. Super comfortable and very lightweight, but wait to big, I’m a size 8 and bought a size 8 as usual, I never had any problem with the UA shoes before, this shoes are about 2 inches bigger on my feet. I will return them and order probably a size 6 & 7 to see which one fit better. That’s the only reason I’m not giving a 5 starts!!!!

Great fit, support and quality
Size: 6.5, Color: (101) White/White/Metallic Silver
I bought as a gift for my wife, she loves everything about them, the fit, support, and quality. These are to replace a pair of Under Armor shoes that served her well and lasted a long time.

Not a fashion statement, but the best for my feet
I’ve had these for a year & alternate between these & a pair of Nikes & they’re still in great shape. I tried just about every brand in my hunt for walking/light jogging sneakers, and for me, these were by far the most comfortable, even over $160 New Balances & expensive Diadora & ASICS…Adidas Ultraboost etc. Every foot is different - for me, different shoes press against the inner foot bone uncomfortably, and there’s no issue with that here. The sole is thick & cushiony which I find supportive, and my feet don’t feel overly compressed. There is a nice little bounce which each step. True to size. I’d recommend.
