INTRODUCTION
Thank you for choosing one of Asystems’ many quality
mixers� The DM481 Rack Mount Mixer – designed by the
ingenious engineers that have created a variety of mixers
fantastic in style and performance in the past – is an
ingenious device, with the ability to be stacked along side
your other rack-mountable gear – signal processors and
such – this 1 U mixer is the ideal addition to your studio
rack or permanent, live setup� With 8 input channels
(with XLR and 1/4” jacks), a prefader out and auxiliary
in, as well as tone control and muting on each, individual
channel, the DM481 will undoubtedly prove itself to have
been a valuable investment�
FEATURES

● 8 mic / line inputs, each with ultra low noise preamp
circuitry offering up to 62 dB gain (mic in)
● Eight sets of balanced Euroblock mic/line inputs and
1/4” unbalanced line inputs
● RCA Pre-fader output and AUX input for connecting
additional units to maximize the application flexibility
● Mute control on each channel
● Clip indicator on each channel

BASIC SETUP
Getting Started
1.
Ensure all power is turned off on the DM481 Personal
Mixer� To totally ensure this, the AC cable should not
be connected to the unit�
2. All level controls should be set at all the way to the
left and all channels muted to ensure no sound is
inadvertently sent through the outputs when the
device is switched on� All levels can be changed to
acceptable degrees after the device is turned on�
3. Plug all necessary instruments and equipment into the
device’s various inputs as required� This may include
line level devices, as well as microphones and/or
guitars, keyboards, etc�
4.
Plug any necessary equipment into the DM481’s
output jack and pre-fader output� These outputs can
be sent to various devices, such as amplifiers, active
speakers or monitors, signal processors, and/or
recording devices�
5. Plug the supplied AC cable into the AC inlet on the
back of the device ensuring the local voltage level is
identical to that required on your device�
6. Plug the supplied AC cable into a power outlet of a
suitable voltage�
7.
Turn the power switch on�
Channel Setup
1.
To ensure the correct audio levels of each input channel
is selected, every channel should first be muted and
all VRs turned all the way to the left (including the main
output control)�
2. Choose the channel that you wish to set the level of,
and ensure that channel has a signal sent to it similar
to the signal that will be sent when in common use�
For example, if the channel is using a microphone,
then you should speak or sing at the same level the
performer normally would during a performance� If
a guitar is plugged into that channel, then the guitar
should also be used as it normally would be�
3.
Set the level control of the selected channel to a level
that allows the clip LED to illuminate occasionally;
then turn it back slightly to ensure the LED does not
illuminate� This will allow you to make full use of the
channel’s signal�
4. This channel is now ready to be used; you can stop
making the test audio signal�
5. To activate the channel, release the mute button�
6. You should now select the next channel to set and go
back to follow steps 1 through 5�
Note: it is possible to connect two DM481’s together
through the Prefader Outputs and AUX Bus Inputs of
each, allowing a total of 16 inputs to be used, all controlled
through a single fader (or both faders, and sending the
same signal to 2 separate external devices)�
