8. Basic Setups
This chapter describes the most common possible setups and use cases.
8.1 Using the AUDIO 8 DJ as system’s standard audio device
Using the AUDIO 8 DJ as standard sound card of your operating system will bring brilliance
in your living room when listening to music or watching DVDs via your computer.
8.1.1 Using the AUDIO 8 DJ in Windows
Open Start > Control Panel > Sounds & Audio Devices.
Click on the Audio tab.
As Default Device for Sound Playback, choose one of the available channel pairs of
the AUDIO 8 DJ, e.g. AUDIO 8 DJ (CH. D, Out 7|8).
Make sure the volume controls of the amplier are completely turned down!
Plug a RCA cable into out 5|6 of the AUDIO 8 DJ and connect it to a free input pair
of your amplier.
Open an available music le or sound of your computer. It should get played back via
the AUDIO 8 DJ now.

8.2 Using the AUDIO 8 DJ with a CD player
Make sure the volume controls of the amplier are completely turned down!
In the settiNgs tool or on the AUDIO 8 DJ, choose Timecode CD/ Line as iNput moDe.
Connect the RCA cable of your CD player to a free input pair of the AUDIO 8 DJ, e.g.
AUDIO 8 DJ (CH. A, In 1|2).
Put a CD in your CD-Player and start playing it.
8.3 Using the AUDIO 8 DJ with a Turntable
Make sure the volume controls of the amplier are completely turned down!
In the settiNgs tool or on the AUDIO 8 DJ, choose Phono as iNput moDe.
Connect the RCA cable of your turntable to the input pair of channel A or B of the
AUDIO 8 DJ, e.g. AUDIO 8 DJ (CH. A, In 1|2).
Put a record on your turntable and start playback of your turntable.
8.4 Using a CD player and a turntable side by side
Audio signals coming from a turntable differ from those sent by a CD player in that they
have a very low level. Additionally, their frequency response is distorted according to the
RIAA equalization curve. Because of this, phono signals need to be amplied, and their
frequency response has to be corrected (de-emphasized) during playback. Of the AUDIO
8 DJ’s inputs, channels A and B can handle phono signals, while channels C and D only
offer line level compatibility. The input characteristics of channels A (In 1|2) and B (In 3|4)
can be toggled from Phono to Line in the settiNgs tool or on the AUDIO 8 DJ itself.
So if you plan to use a CD-Player and a Turntable side-by-side, you have to:
leave the turntable connected to channel A (In 1|2) with iNput moDe on Phono and

11.2 How to check if the AUDIO 8 DJ driver is installed correctly
11.2.1 How to check if the AUDIO 8 DJ driver is installed correctly in Windows
Open Start > All Programs > Native Instruments > Audio 8 DJ Driver.
There you will nd the helper applications Audio Statistics, Control Panel and the Settings
Tool. 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 dropdown list, no sample rate values to choose from) there must be something wrong with the
connection. If the AUDIO 8 DJ Driver entry in the NATIVE INSTRUMENTS folder of the
Start Menu is missing, the driver is most probably not installed at all.
If the driver is not installed, you can install it using the setup program as described
in chapter 4.1 (Installation of the AUDIO 8 DJ).
If the driver is not recognized, check your USB 2.0 connection as described in chapter
11.3 (USB Troubleshooting).
As any other USB device, the driver installs exactly for one USB port. If you connect the
AUDIO 8 DJ 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 nd
the right drivers itself.
If you didn’t install the drivers on your computer, Windows will install the wrong drivers.
If you do not know whether or not you have previously installed the drivers of the
AUDIO 8 DJ to your computer, it is advisable, to start the setup program of the AUDIO
8 DJ. If the setup program states that it will rst 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 nd the right driver when it installs the AUDIO 8
DJ on another USB port.

11.2.2 How to check if the AUDIO 8 DJ driver is installed correctly in Mac OS X
In Mac OS X, look into the System Preferences for the NATIVE INSTRUMENTS USB Audio
Control Panel icon. Open this control panel to see if the device is found. If no device is
found, values will appear grayed out. If the NATIVE INSTRUMENTS USB Audio Control
Panel icon is missing here, the driver is probably not installed at all.
If the driver is not installed, you can install it using the setup program described in
chapter 4.1 (Installation of the AUDIO 8 DJ).
If the driver is not recognized, check your USB 2.0 connection as described in chapter
11.3 (USB Troubleshooting).
11.3 USB Troubleshooting
If you experience problems that may be caused by the USB connection between the AUDIO
8 DJ and your computer, check the following chapters rst; several possible sources for
USB issues are covered here.
11.3.1 USB 2.0 required
The AUDIO 8 DJ is an USB 2.0 interface and will not work at all on an USB 1.0/ 1.1
port.
In addition, although the minimum power specied for a USB 2.0 port is 500 mA, we
have seen a few cases where the USB 2.0 ports on certain computers do not fulll the
minimum requirements and therefore do not meet the ofcial USB 2.0 specication. In
this case you may see a message saying that there is not enough power available to operate your device.
In this case you might encounter crackles or it may not work at all.
►
►
Page 43
AUDIO 8 DJ – 43
11.3.2 Try another USB cable
A bad USB cable can be responsible for audio dropouts and other connectivity problems.
It is highly recommended that you try using a different cable if you are experiencing dif-
culties; make sure to use a cable bearing the ofcial USB logo.
11.3.3 Using a powered USB 2.0 hub
It is best to connect the AUDIO 8 DJ directly to a USB 2.0 port on your computer. However,
in certain situations a powered USB hub can also be a solution if you are having problems
connecting your AUDIO 8 DJ to an onboard USB port. In this case you should avoid connecting other devices to the hub if you can as they will take diminuish the total amount
of power available.
11.3.4 Recommended USB-ports (MacBook Only)
As general rule of thumb, do not use the right hand USB port on a MacBook Pro: This
port is connected to the same root hub as the trackpad. With the AUDIO 8 DJ plugged
into the right port, you can encounter audio problems like clicks or dropouts whenever the
trackpad is reactivated from standby mode.
MacBook Pro recommended USB port(s)
For the following laptops the use of USB audio devices on the right-hand USB port is not
recommended:
MacBook Pro 15” 1.67GHz Intel Core Duo and Core 2 Duo

Due to the current USB conguration of the MacBook Pro under OS X, use of USB audio
devices is supported on the left-hand USB ports only (the port or ports next to the power
adapter cable). Use of audio devices on the right-hand USB port is not advised because
it may cause audio interrupts and/ or dropped samples.
However, the use of an iLok dongle on the right-hand port has been qualied and is fully
supported.
MacBook 13.3” recommended USB port
For the following laptops the use of USB audio devices on the USB port closest to the
screen is not recommended:
MacBook 13” White 1.83 GHz Intel Core Duo and Core 2 Duo

MacBook 13” White 2.16 GHz Intel Core 2 Duo
MacBook 13” Black 2.0 GHz Intel Core Duo and Core 2 Duo
MacBook 13” Black 2.16 GHz Intel Core 2 Duo
There are 2 USB ports on the left side of the MacBook models listed above.
Due to the current USB conguration of the MacBook under OS X, the use of USB audio
devices is supported on the front USB port only (the port farthest away from the screen).
Use of audio devices on the rear USB port is not recommended, because it may cause
audio interrupts and/ or dropped samples.
However, the use of an iLok dongle on the rear port has been qualied and is fully supported.

11.3.5 Disable USB energy saving mode (Windows only)
If the AUDIO 8 DJ is causing crashes or performing badly on a Windows machine, disable
power management to the USB hubs rst; XP turns this on by default.
To disable power management for USB hubs, open the device manager (Control Panel >
System > Hardware) and right-click a USB hub to bring up its properties. On the power
management page, uncheck all boxes. Repeat for each hub and reboot.
11.3.6 Update the Driver
Click on the AUDIO 8 DJ logo in the Settings Tool to check the driver version number
and verify that you are using the latest driver.
Check the Native Instruments website regularly for updates of the AUDIO 8 DJ driver.
11.4 How to avoid Ground Loops
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 difcult to nd. 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.
The cause of the noise is usually the computer and its internal devices, or devices connected to the computer like external hard drives. (Note that even if the power supply of
your notebook computer is not connected, your setup may still be vulnerable to ground
noise from an external device with its own power supply.) The cause can also be any other
device (such as a radio or television).
The reason why this noise is present at the monitor speakers input has to do with a loop
in the setup of your electrical and audio cable connections. Most likely this loop occurs
through the ground of one or more of these cables. With this in mind, the following points
should help to eliminate the ground loop.
►
►
Page 46
AUDIO 8 DJ – 46
11.4.1 Try to eliminate the loop
As a rst step, always connect your devices to the same power outlet (e.g. with a
multi-outlet power strip).
Assuming that you have connected your audio interface, the next troubleshooting step
is to disconnect all devices that you are not currently using, but not the amplier and/
or speakers. This also applies to other peripheral devices you may have connected to
your computer (external data storage, CD burners and especially radio or television
cables). In case the ground loop disappeared, you can add the devices one after the
other to see with the connection of which device it reappears.
Another check is to see if the amplier or active monitors create the ground loop.
Monitor your audio signal from the headphones output of the AUDIO 8 DJ via a headphone. Therefore the amplier or the active monitors need to be physically disconnected from the AUDIO 8 DJ. In case the ground loop disappears, you need to lift the
ground on your amplier or the active monitors. Contact the manufacturer of your
amplier/ speakers before lifting the ground to nd out if ground lifting is supported
on your device.
On laptops, low quality power supplies often lead to ground loop noise. Run your laptop on its battery, only to see if the ground loop disappears. In case the ground loop
disappears, you need to lift the ground on your laptop. Contact the manufacturer of
your laptop before lifting the ground to nd out if ground lifting is supported on your
device.
On desktop computers, the computer monitor (screen) might cause the ground loop.
Turn your monitor off and disconnect its power supply while you hear the ground loop.
In case the ground loop disappears, you need to lift the ground on your monitor.
Contact the manufacturer of your monitor before lifting the ground to nd out if ground
lifting is supported on your device.

11.4.2 Break the loop with a DI box (AUDIO 8 DJ only)
If you cannot x the ground noise problem by disconnecting equipment, you still have the
possibility of using a DI (direct input) box after the AUDIO 8 DJ outputs. Most of these
boxes have a ground lift switch on them. This can be used to break the ground loop and
eliminate the noise.
11.5 What is Latency?
As with any digital device (including hardware signal processors) that converts audio to data
and back again, a computer adds a certain amount of delay (“latency”) when processing
audio signals. Fortunately, with today’s computers and low-latency sound card drivers, this
delay can be so small that you cannot hear it (as example: 3 milliseconds is about the
same delay caused by moving your head one meter further away from a speaker). However,
typical computers are generally not set up for low latency; attempting to play in real time
with the AUDIO 8 DJ will probably prove unsatisfying due to the delay.
Any computer-based audio system has some delay between the audio input and output.
As a result, if you are playing a MIDI keyboard through the AUDIO 8 DJ, you may hear an
annoying delay between the time you hit a key and the time you hear the sound. It is easy
to understand that this latency has be kept to a minimum in order to make instruments
and DJ applications playable. Even the most powerful computer can only do a certain
number of calculations per second; generating and processing sounds demands a lot from
a computer. On the other hand, it is important to minimize any computer-based delays in
order to.
Fortunately, three main factors make delays virtually insignicant, assuming you have a
suitable computer setup.
Today’s multi-gigahertz computers allow for very low latencies.
The AUDIO 8 DJ includes drivers optimized for low latency.
The AUDIO 8 DJ has been optimized to work as efciently as possible.
►

Page 48
AUDIO 8 DJ – 48
11.5.1 How low can you go?
1.5 ms of latency approaches the theoretical minimum, because it will always take some
time to convert a human action into something digital and then to convert the digital action
back to analog sound. However, note that ultra-low latency settings (or higher sampling
rates) make your computer work harder, which can affect the performance. So, here are
some tips on living with latency.
11.5.2 About Samples and Buffers
Audio cannot be handled continuously by a computer, but has to wait its turn while other
operations are being carried out. As a result, sound cards create a “buffer,” which can
hold a certain number of samples, where data can be stored and released as needed to
create a smooth ow of data. An analogy would be if you had a hose that does not deliver
water continuously, but in bursts. So you use a holding tank to store the water coming in
from the hose and have a valve in the tank that releases a steady amount of water in a
smooth, continuous ow.
If the tank (buffer) is large, then you can store more water in case the hose goes dry for a
bit. But it will take longer to ll the bucket, which is equivalent to latency. A smaller tank
takes less time to ll, but the hose needs to deliver water on a pretty continuous basis.
All ASIO audio interfaces and sound cards include a Control Panel in which you can adjust
latency. This may be given as the number of samples per buffer or just milliseconds.
The AUDIO 8 DJ provides you with six predened settings (in milliseconds) to choose from
and the option to user-dene the values.

11.5.3 Warning: Different Types of ASIO
It is extremely important to use the ASIO driver written for the AUDIO 8 DJ. There are
also generic ASIO drivers, typically called (for Windows) ASIO DirectX Full Duplex Driver
or ASIO Multimedia Driver. If you’re not sure which one to use, try them all, and choose
the one with the lowest latency. There should be an obvious difference when you use the
correct AUDIO 8 DJ driver.
11.6 Using the AUDIO 8 DJ with a laptop
11.6.1 Check the laptop’s latency
First you should check if your computer can handle real-time audio processing without audio dropouts. Dropouts can be caused by certain components in your computer. A software
utility that can check your computer’s suitability for audio processing is available at:
www.thesycon.de/deu/latency_check.shtml
There is no software installation required, just launch the tool after downloading.
With your audio interface disconnected, the tool will report if your laptop can handle realtime audio streaming without audio dropouts.
In case your computer is unable to handle glitch free audio processing, the tool will show you
red latency bars and report this in the box on the bottom. Run it with both settings – audio
interface connected and disconnected – to nd out about your computer’s capacities.
11.6.2 Avoid Shared Memory
In general it is not recommended to use laptops with shared-memory graphic cards for
audio applications. A shared-memory graphic card accesses the same memory as the
CPU. Other graphic cards have their own, dedicated memory, so that the main memory
is reserved for other tasks (like audio processing). You will need memory and processing
power available for your audio project.

11.6.3 Avoid battery usage
It is not recommended to run the laptop on its battery, as the computer might slow the
clock rate of the CPU down.
11.6.4 Disable devices
First, disconnect additional hardware (printers, scanners etc.) that you do not need while
you are working with your audio interface. Thus, the computer does not need to handle
devices that is currently not being used..
Besides that, laptops often are equipped with built-in devices that tend to disturb audio
processing. An example is a wireless LAN card. In case you experience serious dropouts,
you might need to disable these devices while working with your audio interface.
Disable devices in Windows XP
Right-click on My Computer > Properties > Hardware > Device Manager to open the device
manager. Double-click on a device to bring up its properties dialog. On the bottom of this
pane you can disable the device via the drop-down menu. Deactivate it and hit OK. You
should see a red cross over the device, which means that it has been deactivated.
Common built-in devices are: network adapters, wireless LAN cards, Bluetooth ports, infrared ports, printer ports etc. Try to disable the network adapter and wireless LAN card
rst, as they are the most common problem causing devices in audio processing.
Make sure that you do not disable devices that are indispensable for your laptop to work
properly!
Here is a list of devices that you should not deactivate: System timer, Keyboard, System
CMOS/ real time clock, Microsoft ACPI-Compliant System, Numeric data processor,
Primary IDE Channel, Secondary IDE Channel, Graphics Controller, Ultra ATA Storage
Controllers.
Disable devices on Macintosh OS X
If you have a wireless LAN card installed and Bluetooth running, turn them off while you
are using the AUDIO 8 DJ (you can turn this off in the top OS X menu bar).

11.7 Audio pops, clicks and/ or distortion!
11.7.1 Check your system specs
If your system does not meet the requirements, you may experience pops, clicks and/ or
distortion in audio playback.
For latest system requirements, compatibility and support of the latest operating systems
please see our website at:
http://www.native-instruments.com/audio8dj
11.7.2 Raise the audio latency
Open the coNtrol pANel of the AUDIO 8 DJ (PC) or the control panel of your audio
application (Mac).
Choose a preset with higher latency or, if using user dened settings, raise the USB
and Audio latency.
Keep raising the latency until you do not encounter any more pops/ clicks and/ or
distorts.
11.7.3 Test with the built-in soundcard
Disconnect the AUDIO 8 DJ.
Connect your speaker setup to the built-in (onboard) sound card of your computer.
Play back a track in your standard playback application, e.g. iTunes or Windows Media
Player.
If playback is ne with your built-in (onboard) sound card, there may be an IRQ conict (Windows only) present on the slot or port your sound card is connected to; or
you may need to physically move your sound card to another USB port.

11.7.4 Physically re-congure the AUDIO 8 DJ
Try different USB ports
Connect the AUDIO 8 DJ to another USB port on your computer. Try all USB ports on your
computer until you nd one that works best.
Check your IRQs (Windows only)
IRQ stands for Interrupt Request. This is the way in which Windows allocates resources to
the various devices and ports in your system. If your AUDIO 8 DJ is on a port that shares
an IRQ with other devices, you may have an IRQ conict. This means your sound card is
not receiving the resources it needs to function properly. Here is how you detect an IRQ
conict.
Open Start > Run and type the word msinfo32 and press ok.
Your system information window will appear.
Click the Plus (+) sign next to hArDwAre.
Click on irQs.
Your IRQs will be displayed in the window to the right.
Your USB port will show up as USB universal host controller in the list.
If the IRQ number listed next to any of these ports is sharing with other devices in
your system, you may have an IRQ conict. In this case, physically connect the AUDIO
8 DJ to another USB port.
If this does not work, and your computer is a desktop, you may be able to change the
IRQ allocation from within the system BIOS (depending on your motherboard). However,
with most laptops it is not possible to change IRQ allocation. You may need to reinstall
your operating system for a better IRQ conguration.
