ENGLISH
B. Switching on the computer and the mixer
Boot the computer as usual. Then switch on the mixer. The computer should automatically recognize
the mixer's USB ports without having to install special drivers. If there is no automatic recognition,
check the documentation of your computer for general USB settings or refer to the technical support
of your PC.
IMPORTANT: DO NOT plug or unplug the USB port to or from the mixer during the mixer being
powered up.
C. Software settings
Once the USB ports have been recognized as external sound cards (usually named "USB Audio
Device"). they need to be set in the system settings of the operating system as the standard device
for sound recordings/playback. Example Windows XP © :

"Control Panel"

"Sound and Audio Devices"

"Audio" tab

"Sound Recording" item

Set the USB adapter here as "Standard Device" and confirm with "Apply"

Adjust the level using the "Volume" menu below
Note: settings for other Windows versions (and/languages) may be different but very similar)
OPERATION
Switching on/off
Following a proper power-up sequence protects your equipment – specifically speakers – and your ears.
Follow the below procedure:

Turn down all output volume controls of any equipment in your audio system.
 Switch on your audio sources first (Turntables, CD Players, PC's with soundcards, Tapedecks, etc.)

Switch on the audio mixer

Switch on any audio processor between the mixer and the amplifier(s) [if any].

Switch on the amplifier(s).

Turn up the audio level on your sources if such controls are provided.

Set the audio output of your mixer to a low level.

Set the audio output of any audio processor between the mixer and the amplifier(s) to a medium
level [if any such processors].

Turn up the volume controls of your amplifier(s) slowly.

Make adjustments to all volume settings as needed.
For switching off, follow the inverse sequence – always switch off your amplifier(s) first, then any processors
between mixer and amplifier(s), then the mixer, then the sources.
Some operation guidelines
Apart from using good equipment, good sound comes from using it correctly. Level setting mistakes are one
of the common reasons why even good equipment may not perform as desired. For setting levels, please be
reminded that two guidelines need to be followed:
 Avoid distortion by leaving some headroom. Never overrun any audio-equipment's inputs. Level
meters and displays allow you to make sure that signals do not enter critical levels.

Avoid unnecessary amplification by using as little attenuation as possible. For example, if you turn
down the input gain of a mixer to minimum, and then increase the main output of the mixer to
maximum to drive your amplifier properly, you will create unnecessary noise, as you first dispose of
some already existing signal level, and then later apply amplification (tainted with noise) to make it
up.
Obviously, these two requirements are marking a levelling window that the operator must match to achieve a
good sound with as little distortion and noise as possible.
DANGER: Excessive volume levels on headphones or other sound systems may cause hearing
damage. Always turn the volume control to minimum when you switch the unit on, and do not
exceed healthy listening levels.
