The Hardware in Detail
4 The Hardware in Detail
The KOMPLETE AUDIO 6 processes both incoming audio and the audio sent to your computer
(and external equipment) in analog and digital form. It is a stand-alone device which draws
power from the USB connection of your computer. Thus, an external power supply is unnecessary. The device provides:
▪ sound conversion (from analog to digital and vice versa)
▪ playback/monitoring (from an input device or computer to headphones/speakers)
▪ recording (from analog/digital inputs into digital data)
The KOMPLETE AUDIO 6.
KOMPLETE AUDIO 6 - Manual - 16
The Hardware in Detail
4.1 Front Panel
The front panel of the KOMPLETE AUDIO 6.
(1) INPUT 1 and INPUT 2 (Line and Microphone): These inputs have a combination socket for
use with XLR or 1/4" jack connectors. When connecting an XLR connector, an XLR lock latches. You can easily release the connector by pressing the release tab.
Front Panel
The input GAIN knob lowers/raises the amount of signal going into the KOMPLETE AUDIO 6.
The LINE/INST toggle button selects either LINE mode for strong-signaled inputs (like a synthesizer or the output of an electric piano) or INST for weak-signaled inputs (such as a guitar
or a bass guitar). XLR connected gear is not affected by this button.
(2) MONITOR section: The ON switch turns direct monitoring on/off. With direct monitoring activated, the unaffected input signal will be heard with zero latency. The ON switch also doubles as a monitor selector switch. When held for one second, it cycles through three monitor
modes: monitor signal to outputs OUT 1/2; monitor signal to outputs OUT 3/4; and monitor
signal to both output pairs OUT 1/2 and OUT 3/4. The LEDs from the MONITOR section on the
device's top panel display which monitoring mode is currently active.
The MONO switch toggles the monitor output selection between a mono signal and a stereo
signal. Switching to a mono setting aids in monitoring a mono signal, such as a guitar’s mono
input.
KOMPLETE AUDIO 6 - Manual - 17
The Hardware in Detail
The VOLUME control lowers/increases the output level of the monitor signal.
(3) Headphones section: The PHONES socket is for plugging in headphones with a 1/4" TRS
jack.
The VOLUME control lowers/increases the output signal of the headphones. The toggle switch
1/2 and 3/4 allows you to determine which output is monitored by the headphones.
4.2 Rear Panel
Rear Panel
The rear panel of the KOMPLETE AUDIO 6.
(1) Phantom power button (48V): The phantom power button supplies 48V to condenser microphones, which need this DC voltage to power their active electrical circuitry. This feature eliminates the need for direct boxes or other additional hardware when using a condenser microphone.
Be aware that phantom power can cause serious damage to ribbon microphones. Check
your microphone's manual to see whether it is safe to use phantom power on it. If it
isn't, make sure to disable phantom power on the interface before connecting: Switch
the 48V phantom power button on the device's rear panel off. The 48V LED on the device's top panel stops lighting orange when phantom power is disabled.
KOMPLETE AUDIO 6 - Manual - 18
The Hardware in Detail
(2) USB port: The USB port socket connects the KOMPLETE AUDIO 6 device to your computer
laptop or workstation via USB 2.0.
(3) MIDI: The MIDI input (IN) and output (OUT) sockets connect to MIDI devices such as MIDI
controllers and hardware synths or workstations. These connections also send and receive MIDI
data to and from your computer, and can be utilized by the music software of your choice.
(4) MAIN outputs 1/2: The MAIN 1/2 outs are balanced outputs. Normally, these are coupled
to a mixer, mixing board, or active speakers via 1/4" jacks. However, you can also use RCA
(phono) cables with suitable 1/4" jack adapters.
(5) Outputs 3/4: The OUT 3/4 sockets are balanced outputs. They offer the option of additional
outputs when setting up 4-channel applications, such as surround sound. They also make assigning certain instruments to certain outputs / output pairs or monitoring with a second pair
of speakers possible. These outputs have no dedicated volume control (the output is always at
0 dB) so you will need to control the volume from within your software or the gear they are
connected to.
(6) BALANCED IN 3/4: The IN 3/4 sockets are balanced 1/4" jack sockets. They are used with
synths, tapedecks, CD players, or any other devices or instruments that don’t require phantom
powering.
Rear Panel
(7) IN and OUT 5/6: The RCA (phono) sockets 5/6 are used for digital input/output (ADAT In/
Out), and syncing to external digital clocks. Typically, DAT tapedecks or synthesizers with digital ins/outs utilize these sockets.

On the left-hand side of the Control Panel, you find two tabs: Audio Settings and Diagnostics:
Click on the tabs to open the corresponding page of the Control Panel.
►
Proceed to chapters ↑5.1.1, Audio Settings Page and ↑5.1.2, Diagnostics Page for more information on the Control Panel's pages.
5.1.1 Audio Settings Page
The Control Panel's Audio Settings page.
In the Audio Settings page, you can configure the audio latency and sample rate; monitor the
device's status; enable clock syncing to external devices; and activate direct monitoring.
The Audio Settings page consists of four sections: Audio Processing, Device Monitor, Digital
Sync Source, and Direct Monitoring. See the following subchapters for further information.
KOMPLETE AUDIO 6 - Manual - 23
Advanced Configuration
Advanced Configuration on Windows (Control Panel)
Audio Processing Section
The Audio Processing section in the Audio Settings page of the Control Panel.
The Audio Processing section sets the parameters for the analog-to-digital/digital-to-analog
conversion done by your audio interface. It has two menus:
▪ Sample Rate: Choose a sample rate that is compatible with your music application and
best suited to your computing power. A higher sample rate improves the audio quality, but
also causes higher CPU load. By default, the sample rate is set to 44100 Hz (CD quality).
The sample rate defines how many samples are played/recorded per one second of
sound. A higher sample rate results in higher audio quality; however, 44100 Hz (as
used for recording audio CDs) is a common setting and absolutely sufficient for most
tasks. If your final destination is CD, you should use this setting or a multiple of it
(88200 Hz). For a better understanding: 48000 Hz is used by DAT recorders and for
DVD (films) recording. 96000 Hz and higher rates are typical for DVD, HD DVD, and
Blue-ray Disc audio recording. You should be aware that a higher sample rate also causes higher CPU load.
If you want to use multiple software clients simultaneously with the device, keep in
mind they'll also have to share the same sample rate.
▪ Process Buffer: Lower the buffer size value for a quicker response time from your computer
to audio software and MIDI controller actions.
KOMPLETE AUDIO 6 - Manual - 24
When converting audio information to digital and vice versa, the audio driver needs to
store the data in buffer packages (audio buffers) which are then sent to and processed
by the CPU. The higher the buffer size, the longer it takes for a signal to finally arrive at
the output as audio. You might experience this as a delay between the time you hit a
key on your computer or controller and when you actually hear the sound. This delay is
called latency. A rule of thumb is: lower buffer size results in lower latency. However,
there are more factors to latency than buffer size alone (e.g., CPU speed and RAM size).
You should start off with a higher buffer size setting, and gradually decrease the value
until you find the perfect balance between playability and system performance. If you
experience crackling at the audio output, the chosen buffer size is very likely too low for
your computer’s CPU to cope with, as lower buffer size causes higher CPU load.
Device Monitor Section
The Device Monitor section in the Audio Settings page of the Control Panel.
Advanced Configuration
Advanced Configuration on Windows (Control Panel)
The Device Monitor section displays information about the audio interface's processing status
and your system's output latency. It has two displays:
▪ Processing State: The processing state monitor provides feedback on the current status of
the device. There are three possible status messages:
◦ Idle: interface is connected, but no client delivers audio data.
◦ Streaming: driver is working and processing audio data.
◦ Panic: driver stopped streaming. Too many USB I/O errors occurred in the interface
communication.
▪ Output Latency: Shows the amount of output latency in milliseconds.
KOMPLETE AUDIO 6 - Manual - 25
Advanced Configuration
Advanced Configuration on Windows (Control Panel)
Digital Sync Source Section
The Digital Sync Source section in the Audio Settings page of the Control Panel.
In the Digital Sync Source section, you can select whether the device uses its internal clock or
gets synchronized to the clock of an external device:
▪ Internal (standard setting): Leave this radio button selected if you don't want the device to
be synchronized to the clock of an external device.
▪ External S/PDIF 5|6: Select this radio button if you want the device to be synchronized to
the clock of another external device via S/PDIF. When switching to this setting, the device
automatically tries to establish synchronization to an external clock at the digital input/output 5 and 6 (see also chapter ↑4.2, Rear Panel). If the synchronization request fails, the
interface switches back to internal clock mode. If the synchronization is successful, the top
panel’s Sync LED lights (see chapter ↑4.3, Top Panel).
Direct Monitoring Section
The Direct Monitoring section in the Audio Settings page of the Control Panel.
In the Direct Monitoring section, you can set the device to bypass any signal processing and
send the signal from the input directly to the output of the device (at zero latency).
This function can be accessed from the MONITOR section on the device's front panel
too; see chapter ↑4.1, Front Panel for further information.
The Direct Monitoring section has a button and a drop-down menu:
KOMPLETE AUDIO 6 - Manual - 26
Advanced Configuration
Advanced Configuration on Windows (Control Panel)
▪ Monitor Status: Activating the direct monitoring routes the signal of the inputs 1 and 2 di-
rectly to the selected outputs (see Channel setting below) without sending them through
the computer, so you can monitor the input at zero latency.
▪ Channel: When direct monitoring is active, select to which output channels signals from in-
puts 1 and 2 will be routed.
5.1.2 Diagnostics Page
The Control Panel's Diagnostics page.
The Diagnostics page allows you to monitor performance and detect errors. The information
provided in this page is more of interest to advanced users; however, in case of problems with
the device, you should have a look at this page. The Diagnostics page consists of the four sections: Drop-Out Detection; Connection Monitor; System erformance Test; and Information. See
the following subchapters for further information on these sections.
KOMPLETE AUDIO 6 - Manual - 27
Advanced Configuration
Advanced Configuration on Windows (Control Panel)
Drop-Out Detection Section
The Drop-Out Detection section in the Diagnostics page of the Control Panel.
The Drop Out Detection section provides feedback on USB input/output and buffering errors. It
has two displays and a button:
▪ USB I/O Error: provides feedback on USB connection errors. A high USB I/O Error count
points to your system being overloaded.
▪ Buffer Underruns: Buffer underruns occur when your computer isn't able to process an au-
dio buffer in time. Reasons for underruns include too many ongoing background tasks or
high CPU usage within a music program.
▪ Reset: A click on this button resets the error count.

System Performance Test Section
The System Performance Test section in the Diagnostics page of the Control Panel.
The System Performance Test section provides monitoring of the current DPC (Deferred Proce-
dure Call) latency value of your Windows system. A Deferred Procedure Call is a Windows
mechanism which allows high-priority tasks (such as the basic system tasks) to delay lowerpriority tasks. This specific DPC latency is not to be confused with the overall latency, explained in chapter ↑8.1, Technical Specifications, but it can add to it. The section has two displays and two buttons:
▪ Current Latency: displays the current DPC latency value.
▪ Maximum Latency: displays the highest DPC latency value monitored since the last time
you either started or restarted monitoring.
▪ Reset button: Press this button to reset the Maximum Latency value to zero.
▪ Start/Stop: Press this button to start monitoring DPC latency. Once started, the button la-
bel changes to Stop.

The Input pane of the Audio MIDI Setup utility in Mac OS X 10.6.
The Audio MIDI Setup's Input pane allows for selection of clock source settings, sample rate,
and direct monitoring. The relevant areas/elements here are the Clock source drop-down menu,
the Format: drop-down menu, and the Thru checkboxes, respectively. See the following list for
more detailed descriptions:
▪ Clock source: In the Clock source drop-down menu you can select whether the device uses
its internal clock or gets synchronized to the clock of an external device. This is relevant
when connecting to an external device via the digital In/Out 5/6 sockets (see also chapter
↑4.2, Rear Panel). The drop-down menu holds the following entries:
KOMPLETE AUDIO 6 - Manual - 31
Advanced Configuration
Advanced Configuration on Mac OS X (Audio MIDI Setup)
◦ Internal Clock (standard setting): Leave this radio button selected if you don't want
the device to be synchronized to the clock of an external device.
◦ External Clock (S/PDIF): Select this radio button if you want the device to be
synchronized to the clock of an external device via S/PDIF. When switching to this setting, the device automatically tries to establish synchronization to an external clock at
the digital inputs 5/6 (see chapter ↑4.2, Rear Panel). If the synchronization request
fails, the interface switches back to internal clock mode. If synchronization is possible, the top panel’s Sync LED lights (see chapter ↑4.3, Top Panel).
▪ Format: Choose a sample rate that is compatible with your music application and suited to
your computing power. A higher sample rate improves the audio quality, but also causes
higher CPU load. By default, the sample rate is set to 44100 Hz (CD quality).
The sample rate defines how many samples are played/recorded per one second of
sound. A higher sample rate results in higher audio quality; however, 44100 Hz (as
used for recording audio CDs) is a common setting and absolutely sufficient for most
tasks. If your final destination is CD, you should use this setting or a multiple of it
(88200 Hz). For a better understanding: 48000 Hz is used by DAT recorders and for
DVD (films) recording. 96000 Hz and higher rates are typical for DVD, HD DVD, and
Blue-ray Disc audio recording. You should be aware that a higher sample rate also causes higher CPU load.
▪ Thru: The Thru checkboxes enable direct monitoring. This sends the input signals directly
to its output at zero latency without any internal signal processing. Tick the checkbox of
the relevant channel to activate direct monitoring. This setting is also accessible from the
hardware's front panel in the MONITOR section (see also chapter ↑4.1, Front Panel).
The channels' volume settings cannot be controlled from the Audio MIDI Setup utility;
use the relevant hardware controls (see chapter ↑4, The Hardware in Detail).

Using the Digital Input and Output
6.5 Using the Digital Input and Output
About Digital I/O and S/PDIF
The SPDIF RCA (phono) sockets 5/6 on the rear panel of the KOMPLETE AUDIO 6 are digital
connectors employing the S/PDIF (Sony/Philips Digital Interconnect Format) transfer protocol.
S/PDIF allows for carrying digital audio signals between devices without loss of quality. Typical
users of the RCA (phono) sockets 5/6 would be DAT tapedecks, synthesizers and CD players
with digital output.
In essence, Digital I/O transmits digital information in both directions (using two mono RCA
cables). The electronic data transferred is digital data and gets translated to sound waveforms
via S/PDIF. For this connection, a digital RCA cable should be used, although it is also possible to use standard RCA (phono) cables.
In order for the transfer to work, the devices need to be synchronized with each other, whereby
one of the devices acts as a master and sends a syncing signal and the other acts as a slave
and syncs to it. The KOMPLETE AUDIO 6 can be set to act as a slave, and sync to external
devices in such a setup.

6.6 Direct Monitoring
In the Monitor section of the KOMPLETE AUDIO 6 audio interface, you can set the device to
bypass any signal processing and send the audio signal from the input directly to the output of
the device at zero latency. This function is known as Direct Monitoring.
The Direct Monitoring feature only applies to inputs IN 1/2 and is not available for inputs IN 3/4 and IN 5/6.
You can activate Direct Monitoring via the ON switch in the Monitor section, which is located
on the front panel of the KOMPLETE AUDIO 6. This routes the signal of the inputs IN 1 and
IN 2 directly to the selected outputs. The ON switch also doubles as an output MONITOR se-
lector switch. When held for one second, it cycles through three monitoring modes:
▪ Monitor signal to outputs OUT 1/2
▪ Monitor signal to outputs OUT 3/4
▪ Monitor signal to both output pairs OUT 1/2 and OUT ¾

The information provided in this chapter should help you to solve most of the problems you
may encounter while you are using the KOMPLETE AUDIO 6.
7.1 Solving Hardware-related Problems
All Native Instruments products are extensively tested in real life situations during the development phase. However, if you encounter any problems with your hardware, please check the following points:
▪ Verify that you have installed the latest driver and the latest software update. Check the
Native Instruments website for further information.
▪ Make sure the KOMPLETE AUDIO 6 interface is connected to a USB 2.0 port on your com-
puter (see also ↑7.3, Troubleshooting (Windows)).
▪ Make sure the KOMPLETE AUDIO 6 is connected directly to a USB port of the computer
and not through a USB hub (see also ↑7.3, Troubleshooting (Windows)).
▪ Replace the USB cable (see also ↑7.3, Troubleshooting (Windows)).
▪ Disconnect all other USB devices from the computer (except keyboard/mouse if not built
in).
▪ Try using another USB port on your computer (see also ↑7.3, Troubleshooting (Windows)).

How to Check Whether the KOMPLETE AUDIO 6 Drivers are Installed Correctly
7.2 How to Check Whether the KOMPLETE AUDIO 6 Drivers are Installed
Correctly
Windows
Open Start > All Programs > Native Instruments > KOMPLETE AUDIO 6 Driver. There you will
find the helper application Control Panel. Make sure that the device is connected to the computer and open the Control Panel. If all the drop-down menus are grayed out (i.e., there are no
presets in the preset drop-down list and no sample rate values to choose from) there must be
something wrong with the connection. If the KOMPLETE AUDIO 6 Driver entry in the Native
Instruments folder of the Start Menu is missing, the driver is most probably not installed.
▪ If the driver is not installed, you can install it as described in chapter ↑2, Installing KOM-
PLETE AUDIO 6.
▪ If the driver is not recognized, check your USB 2.0 connection as described in chapter
↑7.3, Troubleshooting (Windows).
▪ As any other USB device, the driver installs exactly for one USB port. If you connect the
KOMPLETE AUDIO 6 to another port, a standard Windows dialog opens in which you can
install the driver to that port. If you have previously installed the driver on your computer
once, Windows will find the right drivers itself once that you start the driver installation
procedure.
▪ If you do not know whether drivers were installed correctly, it is advisable to start the setup
program of the KOMPLETE AUDIO 6 again (see chapter ↑2, Installing KOMPLETE AU-
DIO 6). If the setup program states that it will first uninstall the drivers, you already have
installed the drivers on your computer. In this case you can connect the device to any other
USB port and Windows will find the right driver when installing the KOMPLETE AUDIO 6
on another USB port.
Mac OS X
On Mac OS X, open the System Preferences; with the device connected and the driver installed, the KOMPLETE AUDIO 6 icon should be listed in the Other section.
▪ If the icon is missing here, the driver is probably not installed.

Resolving Ground Loop Issues
7.7 Resolving Ground Loop Issues
Ground loops are a common problem within any environment where multiple electrical devices
are connected to the same power circuit. In complex setups, the cause(s) of the noise can be
difficult to find. Ground loops are perceived usually as a hum or buzz in your audio signal, but
this can also transmit and amplify other sounds from the devices connected to the circuit. For
example, one very common problem is that you hear internal clicking sounds created by your
computer.

8.2 About Latency and Buffers
When converting audio information to digital and vice versa, the audio driver needs to store the
data in buffer packages (audio buffers) which are then sent to and processed by the CPU of
your computer. The larger the buffer, the more delay. You might experience this as late response between hitting a key on a controller which controls music software on your computer,

and hearing the sound at the output. Fortunately, with today’s computers and low-latency
sound card drivers, this delay is usually very low (e.g., three milliseconds is about the same
delay caused by fingers snapping one meter away from your ears). Latency must be kept at a
minimum in order to make software instruments and DJ applications playable.
How Low Can You Go?
1.5 ms of latency approaches the theoretical minimum because it will always take some time
to process information in a computer. Note that ultra-low buffer size settings (as well as higher
sample rates) make your computer work harder, which can affect the performance.
See ↑5.1.1, Audio Settings Page (Windows) and ↑5.2.1, Input Pane (Mac OS X) for instructions on how to adjust buffer sizes, sample rates for shorter latency.
For Windows users: If you cannot get rid of audio dropouts, crackles and noises by adjusting buffer size and sample rate settings, you might also check your system for DPC
latency problems (see the "System Performance Test" section of chapter ↑5.1.2, Diag-
nostics Page for mor info on DPC latency) using the DPC Latency Checker program,
which is found on the web at http://www.thesycon.de/eng/latency_check.shtml.
Appendix
8.3 Different Types of ASIO (Windows)
It is extremely important to use the dedicated ASIO driver written for the KOMPLETE AUDIO 6
and installed during software installation (chapter ↑2, Installing KOMPLETE AUDIO 6). However, ff your system also provides generic ASIO drivers, typically called ASIO DirectX Full Duplex
Driver or ASIO Multimedia Driver, and you cannot get the KOMPLETE AUDIO 6 driver to work
at low latencies, try them all and choose the one that provides the best performance.
