SPL Phonitor 3


SPL Phonitor 3

The headphone amplifier and monitoring controller with 120V technology

Phonitor 3 is the ultimate headphone amplifier and monitoring controller with 120V technology. It offers the same monitoring quality as the big SPL mastering consoles –
on loudspeakers and headphones.

The analog Phonitor Matrix allows mixing and mastering on headphones in the highest quality – with the same spatial perception of the stereo stage as on loudspeakers.

Three analog XLR stereo inputs for various sources and a wide range of monitoring options make it the perfect monitor controller for demanding producers and mixing/mastering engineers.

Phonitor 3 can be equipped with the optional Expansion Rack, which is not only a 19" rack housing, but it also expands the connection possibilities with three additional switchable stereo outputs for active loudspeakers or power amplifiers.

The ultimate headphone amplifier and monitoring controller!

Great sound – for headphones

The Phonitor 3 offers connection for a standard headphone with a stereo jack plug on the front. Thanks to the enormous output power, all kind of 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 of the device, Phonitor 3 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
Phonitor 3 offers the same key technology – SPL 120V technology – and signal 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.

Free choice
Up to three stereo sources can be connected to the Phonitor 3. The source is selected via the Source switch.

Analog inputs
Three analog stereo inputs are off ered, each with two XLR line inputs (left channel, right channel). Professional analog players with balanced outputs and line level can be connected here, for example high-quality DA converters or an audio interface.

Milled from solid
The massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further and provides perfect control of the monitoring level.

Monitoring without any compromises
The Phonitor 3 is a full-fledged monitor controller:

  • Source selection
  • Phonitor Matrix with Crossfeed, Speaker Angle and
  • Center Level (the latter can be switched off)
  • Mono/Stereo
  • Laterality control
  • Solo L/R
  • Phase inversion for L and R
  • L/R Swap
  • Output switchable to headphones or speakers
  • Mute

Mono or stereo – a matter of setting
The Mono/Stereo switch can be used to select whether the output signal of the Phonitor 3 is a regular stereo signal or whether it is summed to a mono signal.

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 3 has the uniquely fi nely resolved laterality control, which rebalances the stereo image on the monitoring side. The Mono/Stereo switch can not only be used to switch between stereo
or mono playback. This switch is also used to activate or deactivate the laterality control.

Solo L/R
Only the right or left channel of the audio signal should be played back? The Solo L/R function makes it possible. If the triple selection switch is in the “L” position, only the left channel is played back – if it is in the “R” position, only the right channel is played back. In the middle position “Off ” the Solo function is switched off . The regular stereo signal consisting of the left and right channel is thus present at the output of the Phonitor 3.

L/R Swap
A special feature is the channel swap function: L/R Swap. This function inverts the stereo image. Left becomes right and right becomes left . This is especially important and extremely time-saving, when you are monitoring samples in video dubbing that should match a scene with direction of movement. If the direction is not correct, you usually have to load the sample into the DAW to switch channels. before you can judge whether the sample matches the image. With the L/R Swap function, this is no longer necessary. You can now adjust the direction of movement on the Phonitor 3 while pre-listening the sample library.

Phase inversion for L and R
With this switch the phase of the left or right channel of the audio signal can be inverted. If the three-way selection switch is in the “L” position, the left channel is inverted – if it is in the “R” position, the right channel is inverted. In the middle position “Off ” this function is switched off . At the output of the Phonitor 3 the regular stereo signal is thus present.

M/S – Mid or Side?
By using the mono/stereo and L/R phase inversion switch in combination, it is also possible to only monitor the mid or side signal. When 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 diff erent from listening on loudspeakers. The biggest diff erence 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.
