Great sound – for headphones
The Phonitor 2 offers connection for a standard headphone with a stereo jack plug on the front.
Thanks to the enormous output power, all headphones are driven effortlessly. Thus, it plays out the advantages of the SPL 120V technology and rewards the listener with an honest, detailed and at the same time vivid sound experience.
Great sound – also for loudspeakers
On the rear panel, the Phonitor 2 offers a stereo output which makes it a high-quality monitoring controller for any monitoring situation. Active speakers with an integrated power amplifier or passive speakers in combination with a power amplifier can be connected at this output.
Monitoring at the highest level
The signal quality of the Phonitor 2 offers the same quality as the big SPL DMC and MMC mastering consoles.
Headphones or Speakers
The OUTPUT switch – simply switch from headphone to speaker playback.
In the center position (Mute), no signal reaches the outputs. The VU meters light up red.
With a dip switch on the bottom of the device, the volume control for the rear stereo output can be switched out of the signal path.
Would you like a little bit more?
The SPL Expansion Rack is not only a 19” rack housing for the Phonitor 2, it also expands the connection possibilities.
A passive four-way switch integrated into the Expansion Rack allows the Phonitor 2 speaker output signal to be switched between up to four stereo speaker pairs.
On the input side, three stereo analog inputs are offered.
XLR inputs 1 and 2 are optimal for connecting balanced sources, such as for example a high quality DA converter or audio interface.
RCA input 3 is perfect for connecting, for example, a CD player or other similar sources with RCA outputs.
When a CD player or other hi-fi equipment is connected to the RCA jacks, the consumer level can be increased from -10 dBV to 0 dBu with a dip switch on the bottom of the device. In this way, the sources are better comparable in terms of their level.
Milled from solid
The massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the motorized Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further and provides perfect control of the monitoring level.
The volume control can be remotely controlled with any infrared remote control.
The Phonitor 2 learns to communicate with it with the simple push of a button.
“I think SPL sounds very reliable, solid and above all lifelike. You don’t need more words for top quality.”
Monitoring without any compromises
The Phonitor 2 is a full-fledged monitor controller:
- Sources: 2x XLR, 1x RCA
- Solo L/R
- Phase inversion for L and R
- Output switchable to headphones or speakers
- Phonitor Matrix with Crossfeed, Speaker Angle and Center Level (the latter can be switched off)
- Laterality control
Finding the real center
Naturally, hearing can be directed more to the left or more to the right. This becomes particularly clear when listening on headphones.
Therefore, the Phonitor 2 has the uniquely finely resolved laterality control,
which rebalances the stereo image on the monitoring side.
The Mono/Stereo switch not only selects between stereo or mono playback.
This switch also activates the laterality control.
M/S – Center or Side?
By using the mono/stereo and L/R phase inversion switch in combination, it is also possible to only monitor the center or side signal. When the switch is set to “Mono” and phase inversion is active for L (or R), only the side signal is played back. If the phase inversion is switched off, the mono signal corresponding to the “M” signal is played back. Separate monitoring of the M and S signals has become a widespread standard for many mixing and mastering engineers.
Everything at a glance
Two mechanical VU meters visualize the input levels for the left and right audio channels.
The “VU Cal” switch can be used to reduce the signal visualized on the VU meters by -6 dB or -12 dB.
Thus, the VU meters operate in the ideal display range even at very high input levels.
The Revolution: Phonitor Matrix
The Phonitor Matrix is the revolution in the headphone amplifier.
One of the unique features of SPL headphone amplifiers is the SPL Phonitor Matrix. It enables mixing and mastering engineers to create perfect mixes on headphones, which will translate perfectly to all types of stereo speaker systems.
But the Phonitor Matrix is not only designed for professional use in the studio. It also enables the hifi enthusiast to enjoy music on headphones, like if it was played back on speakers.
How is this possible?
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 stage and sound sources are not played back at their actual position in the stereo spectrum.
The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry.
The Phonitor Matrix parameters
The two main parameters of the Phonitor Matrix are Crossfeed and Angle:
Crossfeed determines the crossing signals of the channels.
Angle determines the opening angle of the stereo image.
Level and frequency corrections of the right (red) and left audio channel (green) at maximum crossfeed.
Settings for the speaker placement angle to determine the interaural time difference.
During conventional listening on headphones, our brain can compensate a certain level of false playback representation – but this is very exhausting and leads to listening fatigue.
To make the listening experience even more perfect, the level of the center of the stereo image needs to be attenuated when the Phonitor Matrix is active. This ensures that not only the position of all sound sources is correct but also their volume.
In most Phonitor devices this value is set to a fixed attenuation of -1 dB, which is the best choice for getting an authentic representation of the sound stage. Only Phonitor 2, designed for the most advanced mixing and mastering applications, allows to adjust the center level in 0.3 dB steps with the „Center” switch. (Bild: „Center“)
The SPL Phonitor Matrix corrects the false representation of the stereo sound image, which makes it much easier to find the right decisions for mixing and mastering engineers. The hifi enthusiast can experience the music, like it was originally mixed and recorded.
So nothing stands in the way of a successful and long mixing session on headphones.
