Manual

Getting started

Read the safety instructions starting on page 11.
Make sure that the mains voltage of the Phonitor 3 corresponds to the voltage of your region and that the fuse has the correct value for the selected voltage (see specifications on page 8.)
The power switch on the back of the Phonitor 3 must be in the off position.
(Off = O / On = I).
Connect the supplied power cord to the power connector of the Phonitor 3 and to a power outlet.
Be sure to connect the device to a main socket outlet with a protective grounding connection!
If the supplied power cord does not match your mains socket outlet, please contact your dealer.
The devices that are to be connected to the Phonitor 3 must be be switched off.
Connect the outputs of your analog sources to the analog inputs of the Phonitor 3.
Please use appropriate audio cables (XLR).
Audio cables not included in the scope of delivery.
Connect audio cables between the Phonitor 3 and following amplifiers or active monitors (XLR).
Audio cables not included in the scope of delivery.

Connect headphones to the headphone outputs of the Phonitor 3.
Warning: Never connect a mono jack to the stereo headphone jack and make sure that the plug is fully inserted, otherwise a short circuit might damage the amplifiers.

Power on
Switch on the power switch on the rear panel of the Phonitor 3 (On = I).
The VU meters light up.

Power off
Switch off the power switch on the rear panel of the Phonitor 3 (Off = O).
The VU meters no longer light up.

Source selection
Use the Source switch to select an analog input source.

Phonitor Matrix settings
With the Matrix switch you can activate the Phonitor Matrix – with the Center function (All) or without (Cr/A). In the Off position, the Phonitor Matrix is deactivated.
The Phonitor Matrix creates a speaker-like listening experience on headphones, by mixing the left and right signals, each delayed (interaural time difference) and attenuated (inter-aural level difference), to the corresponding opposite side.

Crossfeed
With the Crossfeed switch you can adjust the interaural level difference. The level difference is comparable to the influence of different room sizes and their reflection and absorption characteristics. The interaural level difference is frequency-corrected because the sound is reflected and absorbed by the head in a non-linear fashion.

Angle
With the Angle switch you adjust the interaural time difference which is related to the placement of the speakers. The interaural time difference is frequency-corrected because the sound is reflected and absorbed by the head in a non-linear fashion.

Center

When activated (Matrix switch = All) you control the intensity of the center signal with the Center switch. If the stereo width is narrowed through changes in Crossfeed and Angle (so as to correspond to your actual loudspeaker setup), the phantom center may likely sound too intense while mixing on headphones. You normally would counteract by lowering the center signals in the mix. However, listening to that mix on loudspeakers the phantom center appears to quiet.
Attenuating the center allows the center signal to be adjusted back to the appropriate ratio of volume in relation to the stereo signal when mixing on headphones, so that the phantom center gains the correct volume in relation to the stereo signal during speaker playback.

Mono/Stereo
By using the Stereo switch you can switch the audio signal to Stereo, Stereo with Laterality control and Mono. In Mono mode, both stereo channels are summed.
The mono signal maintains at the same level as the two channels of the stereo signal are each attenuated by 6 dB before summing.

Solo
With the Solo switch you can monitor the left or right channel of the stereo signal individually. In Off position you hear the stereo signal. Set the Solo switch in position L to hear only the left channel and in position R to hear only the right channel.
With Solo activated you hear the selected channel only on the respective side – this is called “Solo-in-Place”. However, if you like to hear the selected channel on both sides set the stereo switch to mono. This allows you to immediately detect, for example, hether the mid and high frequencies are similar.

Phase Ø
With the phase inversion switch the phase the of the left or right channel can be inverted (180°).
TIP: 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 (M/S). 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.

Laterality
Laterality refers to the deviation of sound perception to either side of the ears. With the Laterality control you can compensate perceived volume differences between channels that may be due to a hearing impairment. This control differs from conventional balance controls. If one channel is attenuated, the other one is increased at the same time. This means that, e.g. when hard left, the level of the left channel increases by 2.25 dB while the right channel is attenuated by 2.25 dB. This control has a narrower range than conventional balance controls. Its resolution is very fine, which means it can be peciseley adjusted.

Set the Stereo switch to Laterality to control the laterality.

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.

Output selection
The Output switch allows you to route the selected source signal to the desired output – headphones or speakers (XLR audio outputs on the rear panel).
In the center position (Mute), no signal reaches the outputs. The VU meters light up red.

VU Meters
The VU meters display the input levels for the selected source.
The meter indicates levels from -20 dB to +5 dB.
0 dB corresponds to +4 dBu.
The ballistics of the VU meters guarantee an optimal visual perception. The time calibration of the VU meters complies with the requirements of the BBC.
The rise time up to 0 dB is about 300 ms.

VU Cal
With the VU Cal switch you can lower the sensitivity of the VU meters by 6 dB or 12 dB. This way the display range can be adapted to higher input levels.

DIP switch
With the DIP switches on the rear of the device, the following basic settings can be chosen:
DIP switch 1: ON = Headphone output is increased by +12 dB.
DIP switch 2: ON = Preamp Out with Phonitor Matrix
The Phonitor Matrix is activated for the XLR outputs Preamp Out.
DIP switch 3: ON = Preamp Out becomes Direct Out (without volume control)
The selected input signal is fed to the XLR output without changing the volume or other parameters (except phase inversion).
DIP switch 4: ON = Direct Out with Phonitor Matrix
The Phonitor Matrix is activated for the Direct Out XLR outputs.
