Getting started
Read the safety instructions starting on page 12.
Make sure that the mains voltage of the Track One Mk3 corresponds to the voltage of your
region and that the fuse has the correct value for the selected voltage (see specications
on page 10).
The power switch on the back of the Track One Mk3 must be in the o position.
(O = O / On = I).
Connect the supplied power cord to the power connector of the Track One Mk3 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 Track One Mk3 must be be switched o.
Connect your devices with appropriate audio cables (XLR) to the inputs and outputs of the
Track One Mk3.
Audio cables not included in the scope of delivery.
Power on
Switch on the power switch on the rear panel of the Track One Mk3 (On = I).
The PWR LED and all activated switches light up.
Activating phantom power
Please always follow these instructions to active and deactivate phantom power – also
when changing microphones. The input stage of the Track One Mk3 can be damaged if
you ignore these procedures.
1. Connect the microphone to the Track One Mk3.
2. Now activate phantom power to use the microphone.
3. Aer recording rst deactivate phantom power.
4. Wait at least one minute aer deactivation of phantom power before disconnecting the
microphone! This ensures residual current will be discharged.
Power o
Switch o the power switch on the rear panel of the Track One Mk3 (O = O).
The PWR LED and all activated switches no longer light up.

Preampliers
The Track One is equipped with two preamps:
a microphone preamp with 48V phantom power and a sepa-
rate instrument preamp. Both are tuned to a sound-neutral,
open and transparent characteristic.
Line/Inst
Track One Mk3 oers the possibility to connect instrument
or line signals. The Line/Inst switch can be used to switch
between the Instr/Line input (switch is illuminated) and the
microphone input.
Instruments and sources with line level can be connected to
the rear input Instr/Line. The Instrument / Line switch is used
for level and impedance matching of instrument and line
signals.
When connecting low impedance line signals, the switch should be pressed.
When connecting high-impedance instrument signals, the switch should not be pressed.
The clip LED “CLIP” lights up as soon as an overload is detected
in the device. The indicator picks up at all relevant points of the
signal flow: behind the preamp, behind the compressor, behind
the equalizer and behind the output control.
Gain
The gain control can be used to adjust the preamplication. For
microphone signals, a preamplication of up to 63 dB can be
realized. When optionally equipped with an input transformer,
approximately +14 dB must be added to the scaled values.
The control range for line signals ranges between -12 dB and +22 dB. The control range for
instrument signals ranges between 0 dB and +35 dB.

48V
The 48V switch activates the required phantom power of
48 volts for the use of condenser microphones.
We recommend to switch o the phantom power for all other
microphone types except condenser microphones.
Tube microphones oen source their operating voltage from the associated power
supply unit and therefore usually do not need phantom power.
Ground
The Ground switch can be used to eliminate ground loops by
disconnecting the internal ground from the housing ground
when the switch is pressed.
The signal LED “SIG.” lights up as soon as an input signal
with a higher level than -30 dB is detected.
A highpass lter with 6 dB per octave reduces impact noise
below 80 Hz.
S-Reduction
The S-Reduction control adjusts the intensity of the S-sound
reduction.
In practice, S-Reduction settings between -2 dB and -8 dB
achieve the best results for most applications.
The S-Detection LED “S-DET.” lights up as soon as an S sound
is detected. It is only active when the de-esser is switched on,
but it works independently of the set reduction value.
In other words, it always indicates that the circuit is detecting
sibilants – so your focus is always directed to a possible need
to control.

The On switch activates the compressor section, consisting of
the compression control and the Make-Up Gain.
Limiter
The Limiter switch puts the compressor into limiter mode. The
threshold is still set by the compression knob.
The limiter is designed as an unobtrusive working so limiter.
Compression
The Compression control can be used to set a threshold
between 0 dB and -20 dB. The lower the threshold, the more
the compressor works.
Make-Up GAIN
The Make-Up Gain control can be used to make up for the
overall level reduction caused by compression. A value
between 0 dB and 20 dB can be set by which the level is
increased again aer compression.
Gain Reduction
The Gain Reduction display indicates the processing that is
being performed with the compressor. The level reductions
due to compression are displayed in 1.5 dB steps.

Track One Mk3 – Manual

Compressor Link
The Compressor Link feature allows to operate two Track One
compressors with one control signal to ensure coherent stereo
results.
The Master/Slave switch determines which device operates as
master and which device is being controlled as slave.
CAUTION – PLEASE NOTE: Never switch two connected units
to Master! Both units would try to control each other – in worst
cases, damaging the units can not be excluded.
Therefore, always follow this procedure when activating
Compressor Link:
1.Determine the master device (switch not pressed).
2.Determine the slave device (switch engaged).
3.NOW connect both Compressor Link sockets with a stereo
jack wiring. Always determining the device status before
connecting the Compressor Link sockets excludes a mutual
control activity.
In Compressor Link mode the master device controls the
Compression, Make-Up and Limit controls of both compres-
sors. The respective controls on the slave unit are deactivated.
The Gain Reduction metering of the master unit now is the
master display for both units.
If the two units are to be used separately again, the wiring
must be disconnected and the slave unit must be set to master
again. (not pressed).

LMF
The center frequency of the half-parametric low/mid frequency
lter is set with the LMF control (low/mid frequencies). The
adjustable frequency range is between 30 Hz and 700 Hz so
that this lter covers a range of about 4.5 octaves, allowing it
to be used from the deepest bass to the lower mid range. This
together with the MHF lter ensures that the entire frequency
spectrum is covered.
The LMF lter operates to the proportional-Q-principle, in other words the bandwidth is
dependent on the selected boost or cut.
MHF
The center frequency of the semi-parametric mid/high
frequency lter is set with the MHF control. (MHF: mid/high
frequencies). The frequency range can be set between
680 Hz and 15 kHz so that this lter covers a range of
4.5 octaves and can be equally be used in the lower
mid as well as the high frequency.
The MHF lter operates to the proportional-Q-principle, in other words the bandwidth is
dependent on the selected boost or cut.
AIR
The high frequency lter in the equalizer module is described
as AIR. A coil-capacitor lter with so called bell characteristics
and a center frequency of 19 kHz comes into operation here. At
this frequency the maximum possible accentuation is +10 dB,
the maximum possible damping is -10 dB.
The -/+ control (right to the LMF control) determines the boost
or cut of the LMF lter.
The maximum values are at +/- 12 dB.
The -/+ control (right to the LMF control) determines the cut of
the MHF lter.
The maximum values are at +/- 12 dB.

Output
The outgoing signal can either be dampened to -20 dB
or further amplied by +6 dB with the Output control to
provide optimal drive to the subsequent units or the optional
AD converter. The selected output level is shown on the
PPM OUTPUT display in the display eld.
The PPM OUTPUT display shows the peak reading of the
output level. This display also serves to level the preamplier.
The balanced XLR and TRS output jacks provide the output
signal. Track One Mk3 oers two outputs connected in parallel.

Röhrenmikrofone beziehen ihre Betriebsspannung o aus dem dazugehörigen Netzteil
und brauchen daher meistens keine Phantomspeisung.
Ground
Mit dem Schalter Ground können Brummschleifen behoben
werden, indem bei gedrücktem Schalter die interne Masse
von der Gehäusemasse getrennt wird.
Die Signal-LED „SIG.“ leuchtet auf, sobald ein Eingangssignal
mit einem höherem Pegel als -30 dB anliegt.
Ein Hochpass-Filter mit 6 dB pro Oktave reduziert Trittschall
unterhalb von 80 Hz.
S-Reduction
Mit dem Regler S-Reduction wird die Intensität der
S-Laut-Reduzierung eingestellt.
In der Praxis erziehlen S-Reduction-Einstellungen zwischen
-2 dB und -8 dB bei den meisten Anwendungen die besten
Ergebnisse.
Die S-Detection-LED „S-DET.“ leuchtet auf, sobald ein S-Laut
erkannt wird. Sie ist erst bei eingeschaltetem De-Esser aktiv,
arbeitet aber unabhängig vom eingestellten Reduktionswert.
Mit anderen Worten: sie zeigt immer an, dass die Schaltung
Zischlaute erkennt – so wird Ihre Aufmerksamkeit stets auf
einen eventuellen Regelbedarf gelenkt.

Über den On-Schalter wird die Compressor-Sektion,
bestehend aus dem Compression-Regler, dem Make-Up Gain,
und dem Limiter-Schalter aktiviert.
Limiter
Der Limiter-Schalter schaltet den Kompressor in den Limiter-,
bzw. Begrenzer-Modus. Der Compression-Regler dient
weiterhin zur Kontrolle der Einsatzschwelle.
Der Limiter ist als unauällig arbeitender
So-Limiter ausgelegt.
Compression
Über den Compression-Regler kann ein Threshold zwischen
0 dB und -20 dB eingestellt werden. Je niedriger der
Threshold, desto mehr arbeitet der Kompressor.
Make-Up GAIN
Mit dem Make-Up-Gain-Regler kann die durch Kompression
hervorgerufene Gesamtpegelreduktion wieder aufgeholt
werden. Es kann ein Wert zwischen 0 dB und 20 dB eingestellt
werden, um den der Pegel nach dem komprimieren wieder
angehoben wird.
Gain Reduction
Die Gain-Reduction-Anzeige informiert über die Bearbeitung,
die mit dem Kompressor vorgenommen wird.
Die durch Kompression hervorgerufenen Pegelreduktionen
werden in 1,5-dB-Schritten dargestellt.
