SPL Phonitor 2 headphone amplifier, black

Milled from the solid

aluminum is the 45mm large volume knob. Its mass in combination with the motorized Alps RK27 “Big Blue” potentiometer further enhances the “spoon in honey” turning feeling.

Remote control

The volume can be adjusted with any infrared remote control, which Phonitor 2 simply learns.

Just press the IR programming button on the back and then the buttons for louder and softer.

To The Power Amp

or to the active loudspeakers it goes symmetrically via XLR sockets.

Slave Thru

The volume control can be switched off by means of a dip-switch on the bottom of the unit.

The Sources

Two balanced and one unbalanced stereo sources can be connected to Phonitor 2.

If a CD player or other HiFi equipment is connected to the RCA jacks, the consumer level can be raised from -10 dBV to 0 dBu using a dip switch on the bottom of the unit. In this way the sources are comparable in level.

Mechanical VU Meter

visualize the input levels, which can be switched in sensitivity with the VU Cal switch.

Laterality

By its very nature, hearing can be directed more to the left or more to the right. This is particularly evident when listening with headphones.

That’s why Phonitor 2 has the finely resolved Laterality control. With it the center can be set perfectly.

The Revolution

in the headphone amplifier is the Phonitor Matrix, thanks to which you can create and evaluate your production through headphones in the same way as through speakers.

To achieve this, the super stereo effect must be corrected. It makes the placement of voices and instruments in the stereo image appear to be more widely distributed and effects like reverb and delays are overdone.

The Phonitor Matrix Parameters

Crossfeed
Level and frequency corrections of the right (red) and left audio channel (green) at maximum crossfeed

Speaker Angle
Settings for the speaker placement angle to determine the interaural time difference.

Expansion Rack

The Phonitor 2 can be installed in the Expansion Rack to be screwed into a 19-inch rack.

The Expansion Rack is equipped with a switch that can passively route the stereo output signal of the Phonitor 2 to four stereo outputs.

In this combination, the Phonitor 2 is expanded by three additional stereo outputs.

This expands the  Phonitor 2 to become a full-fedge monitor controller driving full-range, midfield and nearfield stereo speakers.
