For all headphones
The Phonitor x offers connections for standard headphones with jack plug and for balanced headphones a 4-pin XLR connector.
Thanks to the enormous output power of 18 watts, all headphones are driven effortlessly.
Headphones or Speaker
The OUTPUT switch turns the headphone amplifier into a preamplifier – simply switch from headphones to speakers and the selected source signal goes to both analog audio outputs, RCA and XLR.
In the center position (mute), no signal reaches the outputs. The VU meters light up red.
To the power amplifiers
or to the active loudspeakers you can use the balanced XLR- for long, and the RCA sockets for short cable runs.
Practical are the AMP CTL sockets to which power amplifiers with 12V trigger inputs can be connected to switch them on and off together with Phonitor x.
“With the new DAC768xs module, the Phonitor x really shows its phenomenal qualities as a headphone amplifier and preamp, even with digital sources connected.”
Dr. Martin MertensEAR IN
Milled from solid
is the big 45mm Volume control. Its mass together with the motorized Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further.
The red marker LED makes the setting visible even in darkened environments.
Volume RC
The volume can be remote controlled with any infrared remote control, that the Phonitor x simply learns.
To do this, press the IR programming button and then the buttons for louder and quieter.

Learning made easy
This video explains how you can use any infrared remote control to remotely control the volume.
“The Phonitor x is one of the most extraordinary headphone amplifiers on the market with a meticulous level of detail and unrestrained musical playfulness. Period.
Holger BiermannLow Beats
Source of joy
Up to six (6 !) stereo sources can be connected to Phonitor x:
XLR, RCA, USB, Coax, Optical and AES/EBU
Phonitor x accepts a large variety of audio connections. Balanced via XLR or unbalanced via RCA connectors.
With the optional DAC768xs, three additional digital sources can be added.
The DAC768xs
The highly acclaimed AKM AK4490 Velvet Sound™ premium DAC chip is used as the converter chip in the optional digital-to-analogue converter, which thanks to its new architecture reproduces the finest sound details.
It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256.
“I am sufficiently enamored with the Phonitor x that I have decided to buy one; which is the highest recommendation I can give any component.”
Ian DunmoreHeadphones.com
Good ol' times
Two mechanical VU meters visualize the input levels for the left and right audio channel.
Finding the middle
is not always easy. By our very nature, hearing can be leaning more to the left or more to the right. This is especially obvious when listening with headphones.
That’s why Phonitor x has the uniquely finely resolved laterality control. With it, the center can be found perfectly.
With the mode switch you can choose between stereo or mono playback. To the right, the laterality control is switched on.
“In a word: awesome.The Phonitor x always delivered a spotless, honest and tremendously dynamic sound.

The VOLTAiR Technology
What exactly is that?
And what does it do?
Good questions need good answers. And that’s what the 120V video gives you.

VOLTAiR is that good
In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
