Channel 1 of the Audiolink Pro. You can turn on the 48V phantom power for your condenser
microphone if required.
2. Channel 1 Level LEDs: These two LEDs show signal present and clipping for Channel 1.You
should adjust the Gain control so that the signal present is as high as possible, but without the Clip
LED coming on.
3. Channel 1 MIC Gain Knob: This control regulates the level of signal for channel 1 Mic input.
4. Channel 2 XLR MIC input : This XLR balanced connector accepts a MIC level signal for
Channel 2 of the Audiolink Pro. You can turn on the 48V phantom power for your condenser
microphone if required.
5. Channel 2 Level LEDs: These two LEDs show signal present and clipping for Channel 1.You
should adjust the Gain control so that the signal present is as high as possible, but without the Clip
LED coming on.
6. Channel 2 MIC Gain Knob: This control regulates the level of signal for channel 1 Mic input.7.
Direct Monitor Output Jack: when this switch is pressed, you can hear the output sound direct
from the analog input. When you turn your software monitor on, remember to turn the direct
monitor off.
8. Headphone Output Jack: This ¼“ stereo jack plays back outputs 1 and 2 through the Left and
Right speakers of your headphones.
9. Headphone Level Knob: This controls the level of the Headphone Out
10. Power Indicator: This LED indicator lights when the Audiolink pro is receiving power from
the USB port.
Rear panel
The rear panel of the Audiolink Pro houses features providing the following functions:
1. Output 1 and 2 Jacks: This pair of balanced ¼“ jacks provide the output the signal from your
computer and should be connected to a pair of powered speakers, a mixer or a stereo amplifier.
2. Input 1 and 2 Jacks: Using this pair of balanced ¼“ jacks you can connect any LINE level
device or instrument, these also provide HI-Z inputs for electric guitars and basses!
3. Phantom Power Switch: Press this switch to the „In“ position to provide voltage to
microphones that require phantom power on XLR Mic Inputs 1 and 2.
4. Phantom Power LED:This switch lights when phantom power is switched on.
5. USB Jack: This jack connects the Audiolink pro to your computer, using a USB 1.1 (or higher)
connection.
6.Power connector: for external 9V power supply.
Connection and operating devices:
The product case is printed with all relevant information! There are two XLR Mic sockets and the
adjustment switches for the input level next to them. On the front right side you can find the
headphone out and its level control. On the opposite side there are the ¼” LINE/INSTR. inputs, and

4
the LINE outputs. Connect the LINE out sockets with a regular ¼” jack cable to an amplifier. All
outputs, the LINE out and the headphone out, all provide the same mix.
USB Connection
The Audiolink Pro communicates with your computer through a USB port. It is also powered by the
USB connection. Because of this, we recommend that you plug the Audiolink Pro into one of the
built-in USB ports on your computer, not through a keyboard connection or USB hub.
To connect your Audiolink Pro, find an unused USB port on your computer and connect it to the
Audiolink Pro jack with the included USB cable.The computers USB socket will most often be
located on a rear panel and will probably be marked with a symbol looking
something like the one pictured here. When used with Windows XP & Vista, the Audiolink Pro is
class-compliant, making driver installation optional. To start using the Audiolink Pro, you may
simply plug the unit into a USB port . However, choosing to install the driver will allow the
following functions to be added:
Windows XP and Vista – A Device Control Panel and ASIO support with low-latency drivers
Connecting the Audiolink Pro to your computer
Connecting the Audiolink to a computer is very easy! Simply connect your Audiolink Pro with the
included USB cable, to a free USB port on your computer. When the Audiolink Pro is attached the
red POWER LED lights up briefly to signal a good power supply to the Audiolink Pro. The
installation under Windows will then take place automatically, a few seconds after connecting to
your computer-system it will find a "USB Audio Codec" or "USB Audio Device", which can be
used in each application and adjusted in the system control. By using this USB connection your
digitized audio data can now be transferred to your computer!
MIC and MIC/Instrument inputs
Connect your Microphones to input 1 and/or 2, or your electric guitar etc., to the rear panel inputs!
If you use a Microphone, which needs phantom power the phantom power switch is located on the
rear panel of the Audiolink Pro. You can adjust the input levels for MIC/LINE/INSTR. channels 1
and 2 separately with the two Input level controls next to the XLR input sockets.
LINE inputs (stereo ¼” jacks)
Connect your line level device to the two ¼” sockets marked „LINE input“ on the rear panel of the
Audiolink Pro. You can connect any devices with a LINE level output, e.g. Tape deck or CD player.
LINE-outputs (stereo ¼” jacks)
Connect your amplifier to these outputs to monitor recordings or sounds from the computer.
Stereo headphone-output
Connect your headphone to this output to monitor recordings or sounds from the computer.
SOFTWARE INSTALLATION
Windows XP/VISTA
Follow these instructions to install the ASIO2ks ASIO drivers on a Windows XP/VISTA computer.
1. First connect the Audiolink Pro to your computer using the supplied USB cable, turn it on.
2. Windows will detect the new USB device and install the USB audio device automatically.
3. Insert the Software/Manual Installation CD into your CD-ROM drive. Find the asio2ks.cpl in the

5
AudioLink Pro series driver directory.
4. Copy asio2ks.cpl into your System32 folder.
5. Go to Control Panel, double-click ASIO2KS and make your settings.
8. Your Miditech Audiolink Pro is now ready to use.
Control Panel Setup
Once setup is complete, you can control most aspects of the Audiolink Pro using its control
panel.To launch the control panel in your operating system, check the following instructions:
The control panel has the following sets of controls:
Configuration:
Device: Please chose the Audiolink Pro USB audio device.
Output: the 2 channel output of Audiolink Pro.
Format: you can set your Audiolink Pro playback sampling rate from 16bit/44.1kHz~24bit/96kHz.
Input: the 2 channel input of Audiolink Pro.
Format: you can set your Audiolink Pro input sampling rate from 16bit/44.1kHz~24bit/96kHz.
Latency setting: shorter latency time will require more CPU resources, 4~11msec for an average
PC. If you hear interference noise such as a “POP…”, increase latency to higher setting such as
8~20msec.
References to the driver attitude under Windows audio sequencer programs such as Cubase,
sonar or Samplitude:

The Audiolink Pro runs under hard disk recording programs in "Full Duplex Mode" (simultaneous
admission and rendition) but usually only with ASIO Multimedia drivers, the Windows WDM
driver only permits one direction (admission or rendition) at the same time. We recommend that you
download the Audiolink Pro ASIO2ks ASIO driver from our homepage www.miditech.de, or copy
it from the installation CD-ROM. The ASIO2ks driver makes it possible to use monitoring- and full
duplex- modes. Additionally, the latency time of the audio signal will be substantially reduced.
Hard disk-recording software "Magix Samplitude SE"
The bundled software, which is shipped with the Audiolink Pro, is special software for multiple
hard disk recording, cutting and editing recorded music and speech.
Regarding the driver set-up in "Samplitude SE"
To set-up the drivers for Audiolink Pro in "Samplitude SE", click the menus "options" and "system
options" in the „audio set-up“. If you have installed the ASIO2ks driver, you can adjust this here as
a "record and play“ device - please choose the ASIO2ks driver for Audiolink Pro. Below this the
actual latency time will be displayed after selecting the driver, also, by clicking the button
„Attitudes“ you can adjust the buffer size and the latency time of the driver itself. The latency time
is system-dependent and is different in various personal computers. Choose a value as low as
possible, if you adjust too low you hear interference noises, set the buffer and latency time of the
driver just above the noise threshold.
We hope you get a lot of enjoyment from this exciting program! After installation and activation via
www.magix.de this version is fully functioning.
