Thank you very much for choosing a KSdigital monitor
For nearly 20 years, KSdigital has been designing world-class studio monitors, with the goal of repro-
ducing only the transparent, undistorted, true impulse of the music signal. KSdigital products can be
found in the control rooms of top producers, broadcast studios, and mixing / mastering facilities world-
wide. Designed to the utmost specifications of absolute sound neutrality, the monitors of the ADM Series,
C Series, and the new D-Line are uncompromising tools for judging your audio productions in the studio.
Consistency in Design
With the development of the new D-Line, KS has designed monitors that are 100% accurate to the correct
time transmission of the audio signal. When an impulse is accurately reproduced over time, this is equi-
valent to a linear frequency and phase response. This high level of accuracy in the impulse response
comes from drivers specifically developed by KSdigital, in combination with our FIRTEC ™ advanced FIR
filtering found in our own proprietary onboard DSP. The result is that KS has achieved complete sound
neutrality and accuracy in speaker reproduction.
The Coax Series - The Concept
As already established in the successful C Series, the key design feature in the D-Line is the coaxial
construction of the mid-bass driver and high-performance tweeter. This design creates the ideal point
source—without any offset in the horizontal or vertical planes, the listening position achieves the optimal
frequency and phase response. The high frequency horn directs the upper frequency energy directly to
the ear and avoids to a large extent any room reflections. In addition, the reference-quality low frequency
driver prevents any frequency or phase anomalies across the bass range, so the D-Line can reproduce
incredibly high volumes without any of the typical distortion or fatigue found in similar nearfield or mid-
field studio monitors. By using high quality materials such as carbon fiber for the low / mid drivers, a
D-Line monitor provides an exceptionally accurate reproduction of music and speech for its given size.
The powerful built-in amplifiers provide a direct conversion of the electrical signal into pure sound per-
formance. The additional bass driver, with its own dedicated amplifier in the D606 and D808 models,
transmits absolutely accurate bass signals with wavelengths between 10m and 3m (roughly 30 feet and
10 feet). In these larger monitors, the offset between the coaxial chassis and woofer is negligibly small
(only 20cm, or 8”), so even this added component supports the principle of the coax design. The additional
amplifier and extended membrane surface in the CAD-tuned 606 / 808 enclosure create an extremely
accurate, distortion-free, transient-true low bass that allows for the optimal judgement of the sub fre-
quency range of a mix. Whether used as a high quality nearfield monitor in an audio or video editing suite,
as a bridge monitor at a mixing console, or even as a main monitor, the speakers of the D-Line Coax
Series are the ideal tools of choice.
The Digital Signal Processing Aspect
The digital signal processing of the D-Line is based on three filter levels:
1. A phase and impulse EQ filter system: FIRTEC™, to correct the frequency and phase response of each
studio monitor to exacting phase linear standards
2. A ruler-flat digital crossover stage which decouples the woofer / midrange and tweeter at 1.6 kHz
3. A high-pass filter which protects the chassis of the bass / midrange from potentially damaging fre-
quencies that are too low.
This combination ensures the greatest linearity in frequency and phase response, and best supports the
concept of a true point source.
D-Line conception and performance

The Chassis
The principle design—the coaxial chassis—creates the ideal point source. It allows all frequencies to
radiate from one location, without internal phase shifts and regardless of where you are located within the
defined dispersion angle. The carbon fiber cone of the 8” mid / woofer in the D80 and D808 contributes
to this maxim. Carbon fiber is both an extremely stiff and incredibly light material—it ensures clean bass
and high impulse fidelity, without any distortion. For it’s size, the 6.5” mid / woofer of the D60 and D606
reproduces incredibly accurate and deep low frequencies. This low-frequency coated paper driver is
highly damped internally to prevent partial oscillations. The 1” high frequency compression driver ope-
rates through the “pierced heart” of the woofer directly to a stationary horn. This construction prevents
any modulation of the high frequency signal by the movement of the woofer (the Doppler effect). At the
same time, this accurately directs the sound energy toward the listening position, leading to a conside-
rable improvement of the direct sound to room reflection ratio. The mechanical structure of the 1” HF
driver is designed for high volume reproduction, which is no challenge for the D-Line—they can be run
extremely loud with extremely low distortion.
7KH$PSOLêHUV
In the D-Line, the “KSd Class A” type PWM power amplifiers are directly connected to the DSP. By this
direct coupling of the output stages of the DSP to the power amps, a separate D to A conversion is avoided.
A standard D/A converter section is not needed (as is done by other manufacturers in their DSP speakers),
as KS utilizes its own proprietary design that happens between the amp and speaker stage.
„KSd Class A“ Operation
Conventional PWM amplifier designs produce non-linearities even at their lowest volumes. This means
that in each zero crossing of the signal, the distortion increases. The technology and implementation of
the KS PWM design in the D-Line avoids this disadvantage and reverses this ratio. At zero modulation,
the output stage will work with the least distortion values and lowest THD. While this design slightly
increases the heat loss of the amplifier, it leads to a significantly better audiophile quality in the playback.
RESET:
The monitors of the D-Line have a total of five filters that are adjustable by the user. The two on the
front panel give direct access to the High and Low shelving equalizers. Three additional parametric EQs
are accessible and adjustable through the optional RC-100 Remote Control, or the optional FIR W-Lan
software. To return all filters to their linear position, one can reset the speakers to their default factory
setting. Switch the speaker off and turn all three rotary knobs on the front panel all the way to the left.
Switching the speaker on will now reset the parameters. Turning the knobs to the 12 o’clock position will
then reset the speaker to the default factory (neutral) setting.

Heat Sink:
The D-Line studio monitor has two (D60, D80) or three (D606, D808) powerful amplifiers with a
maximum output power of more than 200 Watts per amplifier. The heat sink will be warm during
operation, and must not be blocked or covered—please provide good ventilation around the speaker,
especially the back section. Depending on the operating time, the ambient temperature, and the
volume levels, the heat sink may reach up to 45 degrees Celsius (113 degrees Fahrenheit).

and is designed as a shelving filter (again, see the graphic on the back of
the speaker for reference).
3. Vol – the volume sensitivity control has a range of +/- 6dB, to adjust your
studio monitor to different input levels if needed. Turning clockwise
increases the volume.
4. LED – the blue LED indicates that your studio monitor is turned on.
5. Main switch – the On / Off switch disconnects your studio monitor fully from
