Track One Mk3 – Manual

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.

Track One Mk3 – Manual

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.

Track One Mk3 – Manual

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.

Track One Mk3 – Manual

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.
