Getting started
Read the safety instructions starting on page .
Make sure that the mains voltage of the Phonitor  DAC corresponds to the voltage of your
region and that the fuse has the correct value for the selected voltage (see specications
on page .)
The power switch on the back of the Phonitor  DAC must be in the o position. (O = O /
On = I).
Connect the supplied power cord to the power connector of the Phonitor  DAC and to a
power outlet.
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  DAC must be be switched o.
Connect the outputs of your analog sources to the analog inputs of the Phonitor  DAC.
Please use appropriate audio cables (XLR).
Audio cables not included in the scope of delivery.
Connect the outputs of your digital sources (e.g. Mac or PC, CD player) to the digital inputs
of the Phonitor  DAC using appropriate digital audio cables (USB, S/PDIF coaxial, S/PDIF
optical, AES/EBU).
Digital audio cables not included in the scope of delivery.
For operation on Windows® computers, please download and install the latest driver from the spl.audio page under the “Driver”
section. Since the USB port is Apple Class 2 compliant, Macs, iPhones and iPads do not require additional drivers.
Connect audio cables between the Phonitor 3 DAC and following ampliers or active moni-
tors (XLR).
Audio cables not included in the scope of delivery.
Connect headphones to the headphone outputs of the Phonitor 3 DAC.
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 ampliers.
Power on
Switch on the power switch on the rear panel of the Phonitor  DAC (On = I).
The VU meters light up.
Power o
Switch o the power switch on the rear panel of the Phonitor  DAC (O = O).
The VU meters no longer light up.

Source selection
Use the Source switch to select an analog or digital 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 O
position, the Phonitor Matrix is deactivated.
The Phonitor Matrix creates a speaker-like listening experience on headphones, by mixing
the le and right signals, each delayed (interaural time dierence) and attenuated (inter-
aural level dierence), to the corresponding opposite side.
Crossfeed
With the Crossfeed switch you can adjust the interaural level
dierence. The level dierence is comparable to the influence
of dierent room sizes and their reflection and absorption
characteristics. The interaural level dierence is frequency-cor-
rected 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 dierence
which is related to the placement of the speakers. The inter-
aural time dierence 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 head-
phones. You normally would counteract by lowering the center
signals in the mix. However, listening to that mix on loudspea-
kers 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.
Phase Ø
With the phase inversion switch the phase the of the le 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 o, the mono signal corresponding to the “M” signal is played back.
Solo
With the Solo switch you can monitor the le or right channel
of the stereo signal individually. In O position you hear the
stereo signal. Set the Solo switch in position L to hear only the
le 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, whether the
mid and high frequencies are similar.
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 the same loudness, because both stereo channels are each
reduced by 6 dB.

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.
L/R Swap
This function inverts the stereo image. Le becomes right and
right becomes le.
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 DAC while pre-listening the
sample library.
Laterality
Laterality refers to the deviation of sound perception to either
side of the ears. With the Laterality control you can compen-
sate perceived volume dierences between channels that
may be due to a hearing impairment. This control diers 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 le, the level of the le 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 ne, which means it can be
peciseley adjusted.
Set the Stereo switch to Laterality to control the laterality.

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 chan-
ging 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.
