Phonitor se

OUR ENTRY MODEL INTO THE WORLD OF VOLTAIR HEADPHONE AMPLIFIERS.

The Phonitor se is focused on the essentials – without compromising on quality.
It has the same audio signal amplification as its bigger brothers Phonitor x and Phonitor xe.
With the optional DA converter, it can also play from digital sources.

The Phonitor Matrix provides two of the most common Phonitor Matrix settings as switchable presets. It lets you experience music on headphones as being played back through speakers.

Thanks to VOLTAiR technology in the highest sound quality.

Everything under control

The volume is adjusted with a massive, milled aluminum, rotary knob. The Alps RK27 “Big Blue” potentiometer gives a pleasant “spoon in the honey” rotary feel.
In addition to an analog source, three additional digital sources can be connected to the Phonitor se with the optional DAC768xs.

Headphone Output with Power

The Phonitor se offers a 6.35 mm jack for connecting headphones with jack plug.

Up to 2 x 5 watts of output power is available at this socket. This allows even very power-hungry headphones such as magnetostats or electrostats to be driven effortlessly.

The Revolution: Phonitor-Matrix

The Phonitor Matrix is the revolution in the headphone amplifier.

Thanks to the Phonitor Matrix, music can be experienced on headphones as if it was played on speakers. The tiring super stereo effect is a thing of the past.

Enjoy music without listening fatigue and exactly the way it should be heard.

Unlike the bigger Phonitor models, where the “Angle” switch can be used to select the opening angle of the stereo stage, this parameter is fixed at a default value of 30° for the Phonitor se. The “Crossfeed” parameter can be set in two stages – “C1” and “C2”. “C2” provides higher crosstalk/crossfeed than “C1”.

Music is normally produced and mixed for playback on stereo speakers.

Listening on headphones is different from listening on loudspeakers. The biggest difference is the lack of crossing signals of the sound signal from the left speaker to the right ear and from the right speaker to the left ear. These crossing signals are missing in conventional headphone listening, because there are no signals crossing from one side of the headphones to the other.

This results in an unnaturally wide stereo image and the various sound sources of the audio signal are not localized as the sound engineer intended them to. This effect is often referred to as “super stereo effect”. During conventional listening on headphones, our brain can balance the false representation of the playback to a certain extent – but this is very exhausting.

The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry. The Phonitor Matrix therefore not only ensures a correct representation of the stereo image, but also a relaxed listening experience.

Source of joy

The Phonitor se is equipped with gold-plated RCA sockets for the analog input.
The optional DAC768xs adds three more digital sources: USB, COAX und OPTICAL.

PCM audio is received in S/P-DIF format, both coaxial (RCA) and optical (Toslink F06).
Both PCM audio and DSD audio can be converted via USB.

The DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if a streamer, computer or CD player is connected. No further settings on the Phonitor se are necessary.

The DAC768xs

The converter chip in the optional digital-to-analog converter is the highly acclaimed AKM AK4490 Velvet Sound™ premium DAC chip, which thanks to its architecture reproduces the finest sound details.

It converts PCM audio at 32-bit resolution and a sampling rate of up to 768 kHz, which is 16 times the resolution of a CD. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256.

Unlike the DAC768, which is built into the Director Mk2 for example or available as an option for the Phonitor xe, the DAC768xs does not offer an AES/EBU digital input. The SPL DLP120 with VOLTAiR technology was also not included in the DAC768xs. Nevertheless, it offers a great performance that is unparalleled in this league.

Sounds good

With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.

The VOLTAiR Technology

The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.

The highest possible audio quality requires the highest possible audio operating voltage.

The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.

The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.

By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.

The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.

⭐️⭐️⭐️⭐️⭐️ Perfect for My Suit-Loving 9-Year-Old 🤍👔✨
My 9-year-old is obsessed with suits, and this one was a total win! 😍 The 3-piece set (blazer, vest, and pants) makes him feel so grown-up and confident. The linen material is lightweight and breathable, which is perfect for warm weather ☀️ — and it doesn’t wrinkle easily, which I appreciate as a parent 🙌. He loves that he can wear it different ways — full suit, just vest and pants, or blazer and pants. 👌 The fit looks sharp, and the adjustable waist is super helpful. Perfect for weddings, school events, church, or any time he wants to dress to impress. 💙 Definitely a favorite in our house! 🎉

Adorable special occasion suit for boys
Size: 5, Color: Light Blue, Size: 5, Color: Light Blue
I ordered this 3-piece suit for my son and even though it’s currently a little too big for him, I couldn’t resist keeping it because it’s absolutely adorable! The quality really impressed me right out of the package. The fabric feels lightweight and breathable, which will be perfect for warmer weather, and it has a nice polished look without feeling stiff. The set comes with a blazer, vest, and pants, and each piece is very well made. I love the little details like the lapel on the jacket, the adjustable strap on the vest, and the adjustable waist on the pants, which will definitely help as he grows. It looks like a much more expensive suit than it actually is. Even though my son will have to grow into it, I’m already excited for him to wear it. I’m thinking it will be perfect for Easter next year or any special occasion. It’s such a cute outfit, and I love that the pieces can be mixed and matched for different looks. Overall, I’m really happy with this purchase and can’t wait to see him wearing it! The blue color goes well for any occasion and I may have to order my husband a suit in matching shade of blue so they can be twins. The size looks accurate for boys 5T. I took a picture to show the pants next to a pair of unwashed Oshkosh B’Gosh brand straight leg 5T boys denim jeans.
